UNLABELLED The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. AIM To compare the degree of pharyngeal obstruction in the retropalatal and r...

Selective inflow occlusion (SIO) maneuver preserved inflow of nontumorous liver and was supposed to protect liver function. This study aims to evaluate whether SIO maneuver is superior to Pringle maneuver in patients undergoing partial hepatectomy with large hepatocellular carcinomas (HCCs). Between January 2008 and May 2012, 656 patients underwent large HCC resections and were divided into 2 g...

INTRODUCTION Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular dysfunction. OBJECTIVE To assess whether the performance of the Dix-Hallpike maneuver after the Epley positioning maneuver has prognostic value in the evolution of unilateral ductolithiasis of posterior semicircular canal. METHODS A prospective cohort study in monitored patients at oto...

In this report, a brief history of the Valsalva (Valsalva-Weber) maneuver is outlined, followed by an explanation on the use of this approach for the evaluation of cardiac autonomic function based on underlying heart rate changes. The most important methodological and interpretative aspects of the Valsalva-Weber maneuver are critically updated, and some guidelines are established for simple app...

In this paper we describe the control logic that enabled a small-scale unmanned helicopter to execute a completely automatic aerobatic maneuver. The logic consists of steady-state trim trajectory controllers, used prior to, and upon the exit from the maneuver; and a maneuver logic inspired by human pilot strategies. Extensive flight tests with this control logic demonstrated smooth entry into t...

Introduction: Heimlich maneuver is one of the first-aid maneuvers administered when the upper airway obstruction symptoms develop. Case Report: A 33-year-old female patient presented with sternum fracture due to the Heimlich maneuver. Conclusion: Sternal fracture can be developed after the Heimlich maneuver. In addition, the importance of bedside ultrasonography in the detection of fractures in...

Abstract Maneuver detection and estimation is deemed crucial for maintaining catalogs of Resident Space Objects (RSOs) as it helps to avoid sets duplicated objects track correlation issues. In fact, maneuvers, along with launches break-up events, are the main source potential new object detections during RSOs cataloging activities. For continuous reliable provision Situational Awareness (SSA) T...

PURPOSE The aim of our study was to assess the hemodynamic change of liver during the Valsalva maneuver using Doppler ultrasonography. METHODS Thirty healthy men volunteers were enrolled (mean age, 25.5±3.64 years). The diameter, minimal and maximal velocities, and volume flow of intrahepatic inferior vena cava (IVC), middle hepatic vein (MHV), and right main portal vein (RMPV) was measured d...

OBJECTIVE A Valsalva maneuver is used clinically and on imaging in order to determine female pelvic organ prolapse. We have examined the potential confounding effect of levator co-activation at the time of a Valsalva maneuver and the impact of repetition with biofeedback instruction. METHODS Fifty nulliparous women at 36-38 weeks' gestation received 3D/4D translabial ultrasound investigation ...

BACKGROUND After radiotherapy to the head and neck, many patients experience swallowing difficulties. Preliminary work indicates that these patients benefit from the super-supraglottic swallow maneuver. METHODS Lateral videofluoroscopic studies examined oropharyngeal swallowing in 9 patients who suffered from dysphagia after radiation to the head and neck. Each patient completed two swallows ...
