The maximal pressure that can be generated during an inspiratory effort against an occluded airway serves as an index of respiratory muscle strength. We devised a method that permits accurate measurement of MIP, with near maximal values, and does not require patient cooperation. Twenty-two critically ill intubated patients performed MIP maneuvers before and after coaching. For the initial 11 pa...

The impact of Lecompte’s maneuver on superior vena cava (SVC) has never been mentioned before. We think that in certain anatomical subsets, Lecompte’s maneuver can result in superior vena cava narrowing. We present a case report of patient with Tetralogy of Fallot with absent pulmonary valve with retro-aortic innominate vein who developed SVC thrombosis after Lecompte’s maneuver.

The objective of this paper is to derive a rapid turn-around maneuver for micro aerial vehicles flying in densely cluttered environments, in the form of variable altitude turns optimized for spatial constraints. The design results in a motion primitive which can be implemented on miniature aircraft at large. The primitive is tested on an MAV equipped with just yaw control and no roll control. T...

Current techniques to estimate nitric oxide (NO) production and elimination in the lungs are inherently nonspecific or are cumbersome to perform (multiple-breathing maneuvers). We present a new technique capable of estimating key flow-independent parameters characteristic of NO exchange in the lungs: 1) the steady-state alveolar concentration (C(alv,ss)), 2) the maximum flux of NO from the airw...

INTRODUCTION Atelectasis is a common finding in acute lung injury, leading to increased shunt and hypoxemia. Current treatment strategies aim to recruit alveoli for gas exchange. Improvement in oxygenation is commonly used to detect recruitment, although the assumption that gas exchange parameters adequately represent the mechanical process of alveolar opening has not been proven so far. The ai...

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...
