Background: Supraventricular tachycardia (SVT) is a relatively common dysrhythmia among the general population and a common dysrhythmia presenting to the emergency department. Generally speaking, it is assumed the provider should attempt a vagal maneuver as first-line treatment for SVT, and the most common vagal maneuver used is the Valsalva. Current resources describing the method to perform the Valsalva are vague, and it seems that the exact procedure may vary across clinicians. Even though the Valsalva maneuver is accepted as first-line treatment, there may not be complete compliance with this maneuver and many emergency departments rely relatively heavily on adenosine as absolute treatment for SVT. Currently accepted methods for performing the Valsalva typically describe the patient in a sitting or semi-recumbent position prior to
Clinically, the Valsalva maneuver is considered as main cause of defecation syncope and surgery Hepatic hemodynamics during Valsalva maneuver performed in a patient with functional suprahepatic inferior vana cava (IVC) obstruction during the Valsalva maneuver [12]. Collapsed IVC showed during the maneuver in normal healthy subjects using ultrasonography study, but IVC howed angular appearance and not collapsed during the maneuver in the venography study [10,11]. The change of IVC during the maneuver is ambiguous and hemodynamic contribution of hepatic vein and portal vein during the maneuver has not been studied in normal healthy subjects. Duplex Doppler ultrasonography of the liver provides important information about liver condition [11,13]. Hepatic vein flow depends on hepatic parenchymal compliance, thoracoabdominal pressure, and right atrial pressure. It is known that hepatic vein Doppler waveform is triphasic pattern which is composed of two anterograde flow peaks toward the heart and one ...
Anticoagulants are the treatment of choice for pulmonary embolism. When these fail or are contraindicated, vena cava filters are effective devices for preventing clots from the legs from migrating to the lung. Many uncertainties exist when a filter is inserted, especially during physiological activity such as normal breathing and the Valsalva maneuver. These activities are often connected with filter migration and vena cava damage due to the various related vein geometrical configurations. In this work, we analyzed the response of the vena cava during normal breathing and Valsalva maneuver, for a healthy vena cava and after insertion of a commercial Günther-Tulip® filter. Validated computational fluid dynamics (CFD) and patient specific data are used for analyzing blood flow inside the vena cava during these maneuvers. While during normal breathing, the vena cava flow can be considered almost stationary with a very low pressure gradient, during Valsalva the extravascular pressure compresses ...
The Valsalva maneuver (VM) produces large and abrupt changes in mean arterial pressure (MAP) that challenge cerebral blood flow and oxygenation. We examined the effect of VM intensity on middle cerebral artery blood velocity (MCAv) and cortical oxygenation responses during (phase I, II, III) and following (phase IV) a VM. Healthy participants (n=20 mean ± SD: 27±7 y) completed 30 and 90% of their maximal VM mouth pressure for 10 s (order randomised) whilst standing. Beat-to-beat MCAv, cerebral oxygenation (NIRS) and MAP across the different phases of the VM are reported as the difference from standing baseline. There were significant interaction (phase * intensity) effects for MCAv, total oxygenation index (TOI) and MAP (all P
The second stage of labor is divided into two parts for describing its physiology. In the initial phase, also called the pelvic phase, rotation, alignment, and descent of the presentation part occurs. Ferguson reflex occurs in the late or active phase and the mother pushes spontaneously (5, 28, 29). Lack of attention to the natural physiology of the second stage leads to maternal fatigue and increases labor disorders (29, 30). Moreover, maternal fatigue affects maternal perceived pain severity and decreases maternal satisfaction. Reduction in maternal satisfaction affects the subsequent choice of delivery method (31, 32). Maternal fatigue in the second stage of labor may continue in postpartum hours or days and interfere with breastfeeding and the mother-infant relationship (31, 33).. This study showed that spontaneous pushing in the lateral position, compared with the Valsalva maneuver, reduced pain severity in the second stage of labor and fatigue level, but did not shorten the duration of the ...

Persistent foramen ovale (PFO) is considered a cause of cryptogenic stroke and a risk factor for neurological events in young patients. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (TEE). The goal of this study was to evaluate the feasibility of transcranial color Doppler (TCD) and its diagnostic sensitivity compared with TEE. We investigated 420 patients admitted to our department with cryptogenic stroke, transient ischemic attacks or other neurological symptoms. All patients underwent TCD and TEE evaluation. TCD and TEE examinations were performed according to a standardized procedure: air-mixed saline was injected into the right antecubital vein three times, while the Doppler signal was recorded during the Valsalva maneuver. During TCD the passage of contrast into the right-middle cerebral artery was recorded 25 seconds following the Valsalva maneuver. We detected a right-to-left shunt in 220 patients (52.3%) and no-shunts in 159 patients (37.9%)
PURPOSE: To evaluate whether there is any difference in thickness of the distal esophageal wall in various examination conditions including at rest, during Valsalva maneuver and after drinking cold water and to search the optimal condition for transabdominal US examination in diagnosis of esophageal varix. MATERIALS and METHODS: Transabdominal ultrasonography was prospectively performed in forty one patients with esophageal varix confirmed by endoscopy and underlying liver. The thickness of the anterior distal esophageal wall was measured three times consecutively and calculated the mean thickness at rest, during Valsalva maneuver and following drinking cold water. At the same time, the normal control group consisted of forty four normal patients, and the mean thickness was calculated in the same method to established the normal value. Data obtained by both measures were compared and analyzed by ANOVA and Tuckey multiple comparison. RESULTS: The mean thickness of the distal esophageal wall in ...

To dissociate the effects of an elevated blood pressure on the cardiovascular regulatory functions from those of aging in the hypertensive elderly individual, resting hemodynamic measurements and circulatory autonomic functions in 30 elderly (mean age, 66 years) hypertensive (World Health Organization stages I and II) patients were compared with those in 30 healthy elderly (mean age, 65 years) normotensive volunteers. The elderly hypertensive group showed a significantly lower cardiac index and higher total peripheral resistance. beta-Receptor sensitivity, as determined by chronotropic dose of infused isoproterenol, and baroreceptor reflex sensitivity index, derived from phase II, but not phase IV, of Valsalvas maneuver, were only slightly but significantly reduced in the hypertensive group. The variability of heart rate at rest as an index of parasympathetic control of heart was similar between these two groups. Plasma norepinephrine level was significantly inversely related to resting mean ...
ER is most often an incidental ECG finding that may be present intermittently.12 Given the relatively high prevalence of the ER pattern in the general population (5 to 13 percent) in comparison to the incidence of idiopathic VF (approximately 10 cases per 100,000 population), the ER pattern is nearly always a benign incidental ECG finding. There are no specific signs or symptoms attributed to the ER pattern, which is identified through the use of a standard ECG. In the absence of syncope or sudden cardiac arrest, no additional testing is required in persons with the ER pattern. Asking patients to perform the Valsalva manoeuvre may unmask or accentuate the ER pattern. While performing this manoeuvre has been shown to aid in the identification of the ER pattern in high-risk familial ER, the report of this has not been validated and its applicability to broad populations of asymptomatic persons has not been evaluated.13. The diagnosis of ER syndrome is most commonly considered in a survivor of ...

Strenuous exercise can lead to exercise-induced headaches. While this is normally not cause for concern, an exercise session thats a little too strenuous can cause a potentially life-threatening condition. The haemorrhaging takes place between the brain and the membrane that protects and covers the brain. Exercise headaches typically last 24 hours, but some last days. If you get a headache during or after exercise, and it doesnt go away on its own, its time to see the doctor. In fact, if you ever get a headache during or after exercise, see the doctor just to rule this out. Sometimes, certain breathing techniques, like the valsalva manoeuvre, cause excessive pressure to build up and can make you light-headed. Other times, it can cause a headache that starts in the base of the skull, radiating upward. You want to make sure that the headaches are not serious and that its safe for you to continue your workouts. ...
For the past two weeks I have been talking about breathing, concentrating on unusual situations, like conscious hyperventilation and the Valsalva Maneuver. I should probably have started out by talking about something that is a bit more universally applicable.. Lets talk about this: no breathing equals no oxygen equals total exhaustion.. Its storytime: a few months ago I was talking with a very frustrated and discouraged grappler. For the sake of this story, lets call the grappler Fred. Anyway, Fred was a fit guy who did lots of cardiovascular conditioning to help him with his endurance, but had an unusual problem with his grappling. In his own words:. "The situation seems to occur when I train against new people who are very aggressive, usually wrestlers. I try to relax, but it doesnt seem to be working. I still seem to tense up and gas out. But when I fight guys who are so much better than me I can train for a long time and even roll for 30-40 minutes at a time with minimal ...

When rapid ambient pressure increase occurs as in diving or aircraft descent, this pressure tends to hold the Eustachian tubes closed, preventing pressure equalization across the ear drum, with painful results.[4][5][6] To avoid this painful situation, divers, caisson workers and aircrew attempt to open the Eustachian tubes by swallowing, which tends to open the tubes, allowing the ear to equalize itself. If this fails, then the Valsalva maneuver may be used. This maneuver, when used as a tool to equalize middle ear pressure, carries with it the risk of auditory damage from over pressurization of the middle ear.[1][5][7][8] It is safer, if time permits, to attempt to open the Eustachian tubes by swallowing a few times, or yawning, or by using the Valsalva technique of breathing a very small amount of air gently into nostrils held closed by the fingers as soon as mild pressure is felt, before it increases to the point that its release would be painful. The effectiveness of the "yawning" method ...

The diagnosis of brain death (BD) is based on clinical criteria including deep coma, brain stem areflexia and apnoea. Depending on different local guidelines, confirmatory technical tests are sometimes mandatory.1 Since the 1990s, transcranial Doppler sonography (TCD) has found its place in these circumstances and fulfils most of the criteria of an ideal test in confirming BD. To confirm intracranial circulatory arrest (CA) with Doppler sonography, typical flow patterns must be recorded in bilateral intracranial and extracranial brain-supplying arteries.2 A completely absent intracranial flow signal is not a reliable sign to determine CA because this can be due to transmission problems. Inadequate ultrasound penetration of the temporal bone is a major drawback of this technique, making definitive assessment of intracranial flow patterns impossible. Stabilised microbubble ultrasonic contrast agents (UCA) are routinely used in neurological clinical routine when intracranial insonation is ...

In this study, the vagal efferent arc was demonstrated to be unaffected by hypertension, with no difference in RR interval variation with respiration between the three groups. Furthermore, the Valsalva ratio was also similar between the three groups. Study of the baroreceptor-cardiac reflex, however, identified a consistent reduction in BRS with hypertension, irrespective of the method used for study (phase 4 of the Valsalva maneuver, phenylephrine pressor or SNP depressor method; Tables 2 and 3⇑⇑). BRS in the CH and ISH groups was significantly lower than in the NT group, but there were no differences between the two hypertensive groups. This observation is also borne out by the multiple regression analysis, which identified SBP as the single predictor of BRS, independent of age and DBP.. The present study is in agreement with that of Sumimoto et al,18 who found reduced BRS in elderly subjects (assessed only by the pressor method) categorized as having either diastolic hypertension ...
TY - JOUR. T1 - Sinus valsalva aneurizma ruptúra és reruptúra.. AU - Szuromi, Péter. AU - Hejjel, László. AU - Tóth, Levente. AU - Ajtay, Zénó. AU - Papp, L.. PY - 2006/4. Y1 - 2006/4. N2 - Aneurysm of the sinus of Valsalva (SVA) is a rare condition of the aorta. It progrediates slowly and can be hidden for a long time, but during its development it may cause various symptoms due to compression. Rupture of the aneurysm can result in acute heart failure necessitating an urgent operative treatment. We operated on a patient with symptoms of acute heart failure, grade III-IV tricuspid insufficiency, loud systolo-diastolic murmur and an extremely high calculated right ventricular pressure. The echocardiography discovered the rupture of the non-coronary sinus of Valsalva shunting to the right ventricle. During the operation we removed the aneurysm sac, and closed the hole directly with running sutures. The involved non-coronary cusp ruptured in the early postoperative course, so an acute ...

One patient presented with symptoms of increasing nasal blockage and sinus pressure on a background of extensive nasal polyposis. He was subsequently found to have a history of repeated Valsalvas manoeuvre, the cessation of which resulted in a rapid decrease in the amount of extra-osseous gas on imaging. The second patient presented following a minor head trauma with dysarthria from a hypoglossal nerve palsy and neck pain, with extensive intra- and extra-cranial gas including within the spinal canal (pneumorrhachis ...
Are you aware of how important deep breathing exercises can be to your health? Deep breathing can lower your blood pressure, relieve stress, and help clear your mind. It may be the simplest form of exercise available, and one of the most beneficial. Oxygen plays a critical part to every bodily function we have. Perhaps the three most important things we can do for our body are drink plenty of fresh clean water, eat a healthy natural low fat diet, and do deep breathing exercises to increase our ability to oxygenate our blood. These three things make sure our body is fully nourished, and able to produce plentiful energy for all of lifes challenges. Deep breathing to improve your health should be done with purpose and a plan. The first thing is to make sure you are sitting or standing in a position which allows your diaphragm to move freely and without restriction. Wear comfortable clothes which do not restrict your free movement. Many people breathe from their chest and not deeply from their ...
The Zavanelli maneuver is an obstetric maneuver that involves pushing back the delivered fetal head into the birth canal in anticipation of performing a cesarean section in cases of shoulder dystocia. The Zavanelli maneuver is performed only after other maneuvers have failed, as it is associated with high risk to both the mother and the fetus. A review published in 1985 found that 84 of 92 cases of Zavanelli maneuver were successful in replacing the head of the fetus back into the uterus. Risks of the maneuver to the mother include soft tissue damage and sepsis. The Zavanelli maneuver is not performed very often in the United States.

In about one third of all patients with cerebral ischemia, no definite cause can be identified (cryptogenic stroke). In many patients with initially suspected cryptogenic stroke, however, a cardiogenic etiology can eventually be determined. Hence, the aim of this study was to describe the prevalence of abnormal echocardiographic findings in a large number of these patients. Patients with cryptogenic cerebral ischemia (ischemic stroke, IS, and transient ischemic attack, TIA) were included. The initial work-up included a neurological examination, EEG, cCT, cMRT, 12-lead ECG, Holter-ECG, Doppler ultrasound of the extracranial arteries, and transthoracic echocardiography. A multiplane transeophageal echocardiography (TEE, including i.v. contrast medium application [Echovist], Valsalva maneuver) was performed in all patients 702 consecutive patients (380 male, 383 IS, 319 TIA, age 18-90 years) were included. In 52.6% of all patients, TEE examination revealed relevant findings. Overall, the most common

By Winni Jeong. Researchers in Germany viewed a live birth with an MRI machine for the first time in order to study how the fetus and the mothers pelvis interact during birth. As New Scientist reported, the birth took place in 2010, but the video was only released recently. It is the first time such a video has been released to the general public. The study, published in the June 2012 issue of the American Journal of Obstetrics & Gynecology, says that the video shows "the active second stage of labor, when the mother starts performing expulsive efforts with the valsalva maneuver." The researchers stopped the MRI machine before the second stage in order to prevent possible damage to the babys ears from noise of the machine.. MRI, or magnetic resonance imaging, uses radio waves and powerful magnetic fields to create images of structures within the body. This in turn allowed scientists to clearly see the way that fetus and pelvis interact during birth. This scientific advancement could lead to ...

Research Design and Methods A battery of cardiovascular reflex tests was performed in 130 newly diagnosed IDDM patients aged 12-40 yr at mean blood glucose levels of 7.2 mM after insulin had been administered for 3-39 days. Age-dependent lower limits of normal of these tests were defined at the 2.3 percentile in 120 nondiabetic subjects. Tests of heart-rate variation (HRV) included the coefficient of variation (C.V.) and the low-frequency (LF), midfrequency (MF), and high-frequency (HF) bands of spectral analysis at rest, HRV during deep breathing (C.V., expiratory-inspiratory ratio, and mean circular resultant), Valsalva ratio, and maximum/minimum 30:15 ratio. In addition, spectral analysis on standing, the change in systolic blood pressure to standing, and diastolic blood pressure response to sustained handgrip were determined in 50 patients.. ...
B.Fleck raised the question of allowing future science driven spacecraft maneuvers, now that SOHO appears to be more robust than ever since launch. SWAN, SUMER and MDI voiced some interest in performing maneuvers. It was pointed out, however, that during a maneuver some of the extra safety nets currently provided (e.g. star swapping, fallback into Coarse Roll Pointing mode) would not be effective during maneuvers, since roll control would already have been transferred to the Coarse Roll Sensor. It was nevertheless concluded that one would again consider strong scientific cases for spacecraft maneuvers against the risk posed by temporary loss of some of the extra safety features. Although proposals will be accepted and evaluated, they are not encouraged. ...
