Radiographic examination of the esophagus is termed a barium meal or swallow blood glucose uptake by muscle forxiga 5 mg order without a prescription, or esophagram. The pharynx and esophagus may be examined together in one sitting or may be examined separately. To obtain optimal information from the examination and minimize radiation exposure, it is important to have an understanding of the indications and technique for each of these examinations. Description of Equipment Examination of the pharynx and esophagus is generally performed in a fluoroscopy suite that is equipped with a system for rapid sequence filming. Previously cineradiography was utilized, but with the advent of digital processing, this has largely become obsolete. Cineradiography has been replaced by videofluoroscopy, which is a recording of the fluoroscopic image by a videorecorder and magnetic tape, or frequently now onto digital media. Although spatial resolution is less than with cineradiography, it is generally adequate for most studies. It has the advantages of less radiation exposure, easier manipulation of the images, and the ability to record sound. More recently, rapid sequence digital radiography which is capable of rapid sequence filming of up to 6 frames per second (fps) has become available. Advantages of this system include excellent spatial resolution, easy manipulation of the images, including brightness and contrast changes, and relatively low radiation exposures. The chief disadvantages are too few frames per second for some studies and its lack of availability in many departments. This may offer the opportunity to examine deglutition with less (or no) ionizing radiation. The exciting aspect is that to track the swal- low only saline is administered rather than a contrast agent, which potentially is safer for dysphagic individuals. Further research is needed to evaluate this in a swallow-disordered population (Tanaka et al. Videofluoromanometry is gaining acceptance as a study that can provide dynamic as well as functional structural information about deglutition and provides insights as to bolus flow, pressure signatures, and pressure voids that may help target interventions (Reginelli et al. Radiation Exposure and Safety Exposure to radiation occurs with examination of both the pharynx and the esophagus. For this reason, patients should be carefully evaluated before these studies are done to determine with certainty that the examination is indicated. Younger patients are up to 10 times more susceptible to injury from radiation exposure than are older patients. It is now estimated that 1 to 2% of cancers are induced by medical radiation (Smith-Bindman et al. All clinicians ordering tests involving ionizing radiation must be cognizant of the risks and benefits of the procedure. In addition, individuals conducting the examination should have knowledge of radiation exposure and use appropriate protection from radiation, for both the patient and the individuals conducting the examination. Radiation exposure to the patient can be measured in several ways, including skin exposure, gonadal dose, and total body exposure, and expressed in different units, including grays, rads, or seiverts. The seivert is preferred, as it is a unit which has been normalized for the tissue effects of radiation. Different tissues have different levels of susceptibility to radiation, and this is normalized by the seivert measurement allowing comparison of doses independently of the site receiving the radiation. Of particular concern in examination of the pharynx and upper esophagus is radiation exposure to the thyroid. Radiation exposure of the lens of the eye is also an important issue when the head and neck are exposed to radiation. Most modern fluoroscopic machines incorporate safety features to minimize radiation such as beam coning, last frame hold, automatic kVp adjustment, grid removal, and adjustable frame rates. Operators should employ appropriate shielding, reduce screening time to the minimum needed to achieve the required information, and avoid backscatter by removing objects within the beam path. The patient should always be positioned closest to the detector, and staff should stand a minimum of 5 feet from the beam emitter whenever possible. During a normal year, we are exposed to approximately 3 mSv of background radiation. Most fluoroscopic swallowing studies are estimated to deliver doses in the range of 0. Despite care being needed to optimize fluoroscopic swallows, it is imperative to get all the information needed from the study. Therefore, reducing frame rates to minimize radiation dose may not be helpful given that important swallow information may be lost or go undetected. There must be a balance between an effective study and minimizing long-term radiation risk. There is far greater risk to health in missing aspiration or swallow impairment in this age-group, and the clinician should be aware of all factors involved. Indications History and clinical examination provide invaluable information in assessing the dysphagic patient; however, they are unable to detect silent aspiration, one of the leading causes of disability and death in patients with neurological conditions, head and neck cancer, or head and neck trauma or following surgery (Garon, Sierzant, & Ormiston, 2009; Ramsey, Smithard, & Kalra, 2003, 2005). An instrumental examination is required to fully assess the pharyngeal and esophageal phases of swallowing. This examination is indicated in patients presenting with persistent dysphagia, odynophagia, aspiration, pulmonary pathology, chronic cough, regurgitation, weight loss, or, in some cases, symptoms of reflux or esophageal pathology (chest pain or pressure), or in patients after surgery or radiotherapy to the head and neck. Because radiation exposure is involved, careful consideration must be given to performing the optimal study in the shortest possible time. Specific maneuvers or strategies can be tested during the study to enable safe treatment recommendations.

Techniques to measure palatal anatomy and competence using multiview fluoroscopy have long been available and aid in differentiating between anatomic and movement failures when valving for swallow is incompetent diabetes symptoms eye test discount forxiga 5 mg free shipping. The Linguapalatal Valve the anatomy and physiology of the oral and pharyngeal chambers are linked by the linguapalatal valve (or retro-oral portal [Bosma, 1956]), which is created by posterior tongue elevation against the bony palate or against the tensed and lowered soft palate. This valve acts alternately to contain the bolus within the oral cavity and then release it into the pharynx. The linguapalatal valve differs from other pharyngeal valves in the complexity of its role in both oral preparatory and oral transit components of deglutition, and because it is central in the relationship between the initiation of both swallow gestures and bolus transit. During swallow of liquids, especially boluses >1 mL, failure to coordinate onset of bolus transit with swallow gestures is likely to result in nasal reflux, aspiration, or regurgitation. In swallows of other consistencies, and perhaps very small liquid boluses, particularly those associated with mastication, the linguapalatal valve may open repeatedly to allow small amounts of the bolus into the pharynx before swallow gestures are initiated. Because of this normal variability, interpretation of linguapalatal valving failure can only be made if instructions are clearly understood and the patient is able (and trying) to comply. Failure of linguapalatal valving may result in absent pharyngeal transit or in discoordination of the onset of pharyngeal bolus transit with the initiation of sequential swallow gestures. If linguapalatal valving failure results in bolus entry into the pharynx prior to initiation of swallow gestures, strategies that can delay or prolong bolus flow or that employ pharyngeal anatomy and gravity to deflect the bolus from the airway are useful. Such strategies include head/neck flexion and/or rotation, upper body reclining on one side or the other (the degree depending on the impact desired), increasing bolus viscosity (the degree depending on the need), and limiting bolus size to the capacity of the valleculae and piriform sinus. Alternatively or additionally, voluntary preswallow laryngeal closure may protect the airway until pharyngeal transit is complete. Strategies believed to facilitate timely initiation of pharyngeal gestures by enhancing sensory information are widely used and involve manipulation of the characteristics of the bolus (size, temperature, texture, taste) or presenting other stimulation. Dynamic Fluoroscopic sWalloW stuDy 99 When failure of linguapalatal valving results in initiation of bolus transit after initiation of swallow gestures, the bolus will fall into the pharynx partway through the sequence of swallow gestures, or after they have been completed. Depending on the specific impairment, strategies may be aimed at slowing or deflecting the bolus or at facilitating bolus flow. Strategies to slow or deflect the bolus include limiting the amount of the bolus falling into the piriform sinuses (side-leaning and head rotation) until repeated swallow gestures can complete pharyngeal transit. Strategies to facilitate bolus flow include head/ neck extension with voluntary pre-swallow airway closure followed by flexion and head (not upper body) tilting or rotation. In the oropharynx, expansion to accommodate the bolus is achieved by forward movement of the tongue base and flexibility of the lateral walls; obliteration of the cavity is achieved by medial movements of these structures. At the same time, elevation/foreshortening of these structures helps to engulf the bolus and draw it into the esophagus (Kennedy & Kent, 1985). Failure of velopharyngeal valve timing or extent of closure results in leakage of the bolus (or of air) into the nasopharynx and diminished ability to generate oropharyngeal pressures for propelling the bolus through the oropharynx for swallow (or to divert air through the mouth for speech). Observation of velopharyngeal function during speech (plosives and fricatives) may yield insights into velopharyngeal function for swallow. Strategies to compensate for, or improve, velopharyngeal valve closure include head/neck rotation and manipulation of bolus size and/or viscosity. When compensatory strategies fail, other therapies, possibly prosthetic or behavioral, can be guided by findings of the dynamic swallow study. Failure of timing or extent of velopharyngeal valve opening results in competition between respiration and deglutition, particularly during mastication. This can slow meals and decrease the comfort and ease of eating or Compensations of Pharyngeal Chambers and Valves the pharynx switches from respiratory to deglutitive physiology by altering the shape of its chamber and the configuration of its valves. Most of the time, the pharynx is an airway: the linguapalatal valve may be open or closed, the velopharyngeal valve is open, the laryngeal valve is open, and the pharyngoesophageal valve is closed. Failure of any of these valves and/or failure to maintain pharyngeal patency for breathing can, at least, disturb respiration and negatively impact deglutition. During normal swallow, the switch from respiratory to deglutitive valving begins immediately, or even before, the bolus is delivered to the oropharynx (see Chapter 1). During pharyngeal transit the pharyngeal airspace first expands and then is obliterated 100 Dysphagia assessment anD treatment planning: a team approach drinking. Strategies to compensate for an impaired velopharyngeal airway include increasing the time allowed for respiration between swallows. Techniques that accomplish this objective include limiting the size and viscosity of the bolus, the rate of bolus presentation, and the total number of boluses given. Dysphagia due ever, even subtle laryngeal airway obstruction, like other conditions that result in air hunger, can result in intolerance for the obligatory respiratory pause during swallow. Such impairment may affect subtle relationships between deglutition and respiration (Hiss, Strauss, Treole, Stuart, & Boutilier, 2003). Inadequate opening limits the amount of food or liquid entering the esophagus per swallow. Strategies include repeated swallows per bolus on a single respiration, increased and prolonged maximum hyoidlaryngeal elevation and closure, head/neck rotation, flexion or extension, or upper body reclining. Compensatory strategies are aimed at maximizing the effects of gravity on the to either structural or sensory-motor laryngeal valve dysfunction may compromise the last line of defense against aspiration. Failure of timing or extent of supraglottic and glottic laryngeal valve closure results in leakage into the trachea. Strategies available to compensate for ineffective laryngeal closure will depend on the etiology, that is, impaired sensation, reduced movement, altered structure. These strategies generally aim to deflect bolus flow around the larynx and/or to optimize laryngeal elevation and closure.

The epiglottis blood sugar diary order discount forxiga, whether it retroverts or not, is an important obstruction to bolus flow, that is, it diverts the bolus to the lateral pharyngeal gutters, away from the larynx. Absence of epiglottic retroversion for swallow of a very small bolus may not be abnormal. Because head/neck position affects chamber size and shape, neck extension may decrease this distance as well; and n inadequate flexibility of the epiglottis. Speech and feeding or dietary histories, as noted previously, should be consistent with linguapalatal and velopharyngeal findings. Developmental and/ or neurological diagnoses and histories of head/neck (including spinal) abnormalities, surgical intervention, or trauma should reveal consistencies 7. Dss: a systematic approach to analysis anD interpretation 115 with fluoroscopic observations that will, again, guide decisions regarding prognosis and intervention. If consistencies are not identified, further investigation should be considered, including more thorough speech and swallow evaluation and referral to an appropriate physician specialist. Hypopharynx: Hyopharyngeal Chamber, Laryngeal Valves, and Pharyngoesophageal Valve the presence of the bolus in the hypopharynx is associated with increased aspiration risk. Hypopharynx: Timing Transit Duration Analysis: Transit time must be measured to identify abnormality. As in the oropharynx, hypopharyngeal time can be prolonged by failure of gestures that propel the bolus and anatomic or movement abnormalities that impede bolus flow. Interpretation: Prolonged hypopharyngeal transit may be due to: n Failure to coordinate position of the bolus with onset of hypopharyngeal elevating and medializing (engulfing) gestures. When bolus entry to the hypopharynx is uncontrolled, the bolus may enter the hypopharynx prior to initiation of hypopharyngeal swallow gestures. Such a lag between ges- tures and bolus position is likely if the epiglottis is all or partially absent but is also the result of poor bolus containment in the oropharynx. Poor obliteration of the hypopharyngeal space is associated with reduced ability to propel the bolus so that bolus flow is dependent on gravity, increasing time for transfer. Unilaterally or bilaterally, poor or absent pharyngeal wall movement might be consistent with neurological diagnoses, or with a history of, for example, treatment for head/neck cancer. More time is required for transit if space at any level is inadequate for bolus size and the bolus must flow around an obstruction. Interpretation: Interpretation of timing abnormalities in the hypopharynx is dependent on recognizing the consequences of abnormalities in the oral and oropharyngeal chambers for swallow demands on the hypopharynx. For example, poor control of oral residue or early loss of bolus material requires that the hypopharynx and larynx adopt defensive postures and be habitually wary of bolus material even after or between swallows. During fluoroscopic observation of swallow, timing relationships between events can be insightful and predictive. When the piriform sinus spaces are reduced in size due to changes in the hypopharyngeal wall, the bolus material may be funneled directly into the larynx. Analysis: Because some residue is normal, especially in elderly patients, determination of abnormally incomplete clearing is greatly facilitated by measurement. Because of gravity effects, site of incomplete clearing may be best identified at the point of maximum pharyngeal constriction. Additionally, overlap between the piriform sinuses and the larynx in the lateral view, occasionally a source of confusion, can be more clearly understood by comparison to the A/P view. Hypopharyngeal clearing abnormalities can be due to: n Inadequate bilateral or unilateral ryngeal clearing failures, including timing failures, can be associated with greater risk than clearing problems in the oral and oropharyngeal chambers. As noted, voluntary and passive (suctioning) expulsion of residue is easier when residue is in the latter. Fortunately, the lateral gutters (around the epiglottis) and the piriform sinuses divert and store residue if they are intact. When these spaces are missing because of changes in the pharyngeal walls or due to obstruction from foreign pharyngeal wall tone or descending sequential medialization of these walls. Pulsion diverticulae (small pockets developing in hollow organs or weakened spaces due to pressure), for example, may contribute to residue, but their contribution to dysphagia may or may not be significant. Dss: a systematic approach to analysis anD interpretation n Obstruction at any level, due to 117 thickening of structures (laryngeal cartilages, pharyngeal walls, impingement by spinal abnormalities or appliances on the spine). Secondary effects such as proximal dilation and backflow into the oro- or nasopharynx or mouth will suggest the degree of obstruction. Although safety may preclude it, obstruction can only be completely assessed by swallow of a large bolus. Interpretation: Suspected abnormalities leading to incomplete hypopharyngeal clearing must be correlated with neurological, surgical (including head/ neck and spine), and trauma histories. The epiglottic, previously, the epiglottis with its surrounding pharyngeal walls diverts, controls, and at times prevents transfer of the bolus into the hypopharynx. Compared with other valves involved in swallow, this valve differs markedly in complexity and behavioral capabilities. Competence of the laryngeal valve for swallow requires, in addition to range, agility, and coordination of movement, intact sensation and ability to respond to stimulation protectively, even proactively to anticipate a threatening situation. Laryngeal closure adequate to withstand bolus pressures during swallow depends on sensory as well as motor competence. Laryngeal reopening and maintenance of a sufficient laryngeal airway is required for oral nutrition/hydration. Analysis: Supraglottic penetration (contrast material that stays above the glottis) is judged to be abnormal when it is frequent and/or is not ejected during the swallow. Aspiration during fluoroscopy is defined as contrast material that passes into and through the glottis. By far the most helpful construct for describing aspiration timing is that developed by Logemann (1983, p. In our experience, however, rather than referencing aspiration timing relative to "the swallow" or triggering of the swallow reflex, we have found it more useful to specify aspiration timing relative to achievement of laryngeal closure, as observed fluoroscopically (in lateral view, laryngeal closure is inferred from contact laryngeal, and pharyngoesophageal valves divert the bolus away from the airway and draw it into the esophagus.

This is a balloon-tipped catheter introduced through a vein juvenile diabetes diet recommendations buy forxiga australia, such as the jugular, subclavian or femoral, to allow blood returning to the right heart pushing the balloon to where measurement is desired. In evaluating accuracy of fluid-filled blood pressure measurement systems, techniques used in engineering is often employed. The performance of a needle-pressure transducer system can be evaluated through basic mechanical and electrical modeling. The simplest representation of the system is an undamped spring-mass system of natural frequency: fn 1 2 r 2 dp l dV (8. This provides the required fluid coupling that is necessary when the needle is inserted into an artery which is filled with blood. Blood pressure pulsation is transmitted via fluid coupling resulting in the movement of the pressure transducer diaphragm (stainless steel). Compliance which is defined as volume displacement per unit distending pressure, is the inverse of stiffness: C dV dp (8. The consequence of this in the accuracy of blood pressure recording is explained below. As we have seen in earlier chapters that blood pressure waveform is periodic and can be represented by a Fourier series as the sum of a mean pressure and a number of sine waves of fundamental frequency f (heart rate/sec) and harmonics, nf (n = 1,2. For a distortion-free blood pressure measurement system, or one with a flat frequency response, it is necessary that the amplitude ratio Pmn/Pon =1. For the pressure measurement system to record the arterial blood pressure waveform faithfully, it must have sufficient dynamic frequency response (Li et al. This often results in changing the needle size or length of the needle, especially when an additional pressure transducer of different compliance specification is unavailable. The above second-order representation can be applied to evaluate dynamic frequency response of the system. Either a sinusoidal pressure generator or a step-response "pop-test" are common methods to evaluate dynamic frequency response of the catheter system. Commonly, a step increase in pressure is applied against the catheter-transducer system and the balloon which is connected to the same chamber as the catheter is inflated. The pressure in the chamber thus falls to atmospheric pressure, completing the step decrease in pressure. If the catheter system had a perfect dynamic response, then its response would follow exactly the step Hemodynamic Measurements: Invasive and Noninvasive Monitoring 209 decline in pressure. However, clinically and experimentally used cathetertransducer combinations are usually underdamped, resulting in oscillations in amplitudes. C = compliance combination of the catheter and the manometer or pressure transducer (C=Cc+Ct; Cc=compliance of the catheter and Ct= compliance of the transducer). The damped natural resonance frequency, fd is obtained as the inverse of the period of oscillation: fd 1 T (8. This can be obtained from the interval of the peak-to-peak or trough-to-trough oscillations. Most catheter-manometer systems exhibit underdamped responses, where the damping factors are low, typically of 0. The useful frequency range can be estimated by multiplying the resonant frequency by the damping factor. In other words, the measured Hemodynamic Measurements: Invasive and Noninvasive Monitoring 211 pressure is within 5% of the actual pressure. Thus, higher resonant frequencies and greater damping factors (up to critical damping) offer better dynamic frequency response. The step response or pop-test has its advantages of simplicity and rapid tracking of system response. One can apply either a positive step (step increment in pressure) or a negative step (step decrement in pressure). An ideal blood pressure measurement system would follow the step decrease in pressure exactly, with no overshoot or undershoot or time delay. The single resonance peak occurs as the underdamped catheter-manometer system was approximated by the second order system. Hysteresis refers to the differences in outputs with increasing and decreasing blood pressure within the blood pressure range of interest. Blood pressure waveforms that are closer to sinusoidal waveforms require less harmonic components to resynthesize the original waveform and thus place less stringent demand on the frequency response. For instance, the femoral artery can be recorded with a lower dynamic frequency response than either central aortic pressure of left ventricular pressure. This is because the femoral arterial pressure is generally smoother and with rounded dicrotic notch. Blood pressure waveforms that are closer to rectangular waveform require much higher frequency response to resynthesize the waveforms accurately. This is because rectangular and square waves contain an infinite number of sinusoidal or cosinusoidal components. Normal left ventricular pressure, for instance contains much higher frequency components than the femoral arterial pressure. When the blood pressure waveform is recorded with a low resonant frequency and low damping ratio fluid-filled blood pressure measurement system, erroneous phase shifts and large oscillations can be observed. Overestimation of systolic pressure and underestimation of diastolic pressure can be observed.

Each is an important functional complement that the circulatory system cannot be effectively described by its individual parts alone. By virtue of the distributing vascular trees, oxygen, humoral agents, and nutrients are transported to the vital parts of the body and the waste products are removed. The left ventricle pumps blood into the aorta through the aortic valve, perfuse the systemic arterial system and the right ventricle pumps blood into the main pulmonary trunk, perfuse the pulmonary arterial tree. The shape of the left ventricle is in-between conical and semiellipsoidal with its narrow end forming the apex of the heart. These shapes, as well as cylinder and sphere, have been used in ventricular modeling and in image processing. The left ventricular wall is about three times as thick as the right ventricle, thus is able to develop a much higher pressure. The thick interventricular septum, separating the left and 15 16 Dynamics of the Vascular System (2nd Edition) right ventricles, is more closely associated with the pumping action of the left ventricle. This so-called "myocardium" can be further divided transmurally into the inner endocardium and the outer epicardium. Vascular Biology, Structure and Function 17 There are four heart valves involved in the filling and pumping action of the heart. The mitral valve, with just two leaflets, situates between the left atrium and the left ventricle. The right ventricle and the low-pressure pulmonary arterial system on the other hand, are separated by the pulmonary valve. The aortic valve separates the left ventricle from the ascending aorta leading to the high pressure systemic arterial system. Notice the largest pressure drop occurs in the arterioles and the largest amount of blood volume reside in the veins which serve as reservoir. There are considerable similarities among the corresponding anatomical sites of the mammalian arterial circulation (Li, 1996). The aortic arch junction is formed by the ascending aorta, the brachiocephalic artery, the left subclavian artery, and the descending thoracic aorta. There are numerous branches come off the descending aorta at right angles, renal arteries which perfuse the kidneys are such examples. The distal end of the descending aorta is the abdominal aorta which forms the Vascular Biology, Structure and Function 19 aorto-iliac junction with left and right iliac arteries and its continuation. The femoral artery, a well-known peripheral artery, because of its accessibility, continues from the iliac artery. These are the arteries perfusing the upper thighs with the tibial arteries peruse the lower legs and leading to the ankle arteries. The aorta has, comparatively speaking, the greatest geometric taper, with its diameter decreasing with increasing distance away from the ventricle. The common carotid arteries are the longest, relatively uniform vessels, with the least geometrical tapering. It is worth noting here that in humans, both brachial and radial arteries are the most common sites for noninvasive blood pressure monitoring, with radial in particular as wearable sensor site. Veins, unlike arteries are generally thin-walled and have low distending pressures. The superior vena cava feeds into the right atrium and the main pulmonary vein leads into the left atrium with oxygen enriched blood. Veins have a greater total number than arteries and thus the venous system has a much larger cross-sectional area. Under normal physiological conditions, the venous system contains about 75% of the total blood volume in the systemic circulation with the systemic arterial system constitutes some 15%. The pulmonary circulation contains about one quarter the blood volume of the systemic circulation. However, the low operating 20 Dynamics of the Vascular System (2nd Edition) pressure and collapsibility allows veins to increase their volume by several times under a small increase of distending pressure. These valves permit unidirectional flow, thus preventing retrograde blood flow to tissues due to high hydrostatic pressures.
