OBJECTIVE To assess the safety and efficacy of a recruitment maneuver, the Open Lung Tool, in pediatric patients with acute lung injury and acute respiratory distress syndrome. DESIGN Prospective cohort study using a repeated-measures design. SETTING Pediatric intensive care unit at an urban tertiary children's hospital. PATIENTS Twenty-one ventilated pediatric patients with acute lung in...

This paper presents the development of optimal takeoff maneuvers for an AC75 foiling sailboat competing in oldest and most prestigious competition world, America’s Cup. The many challenges to developing these due its nonlinear, high-dimensional, highly unstable dynamics. During maneuver, boat starts water with low speed (displacement mode) increases until it reaches steady-state (the hull stays...

UNLABELLED Benign Paroxysmal Positional Vertigo (BPPV) is a frequent cause of dizziness and despite of the excellent results with its treatment, there is some controversy about management. AIM To assess the efficacy of Epley Maneuver with and without post-maneuver restrictions. STUDY DESIGN Prospective randomized. MATERIAL AND METHOD Fifty patients presenting BPPV of the posterior semicir...

BACKGROUND A noninvasive system for determining left ventricular (LV) filling pressure may help to improve personalized fluid removal goals in hemodialysis patients. We previously showed that the change in photoplethysmography (PPG) pulse amplitude measured by finger PPG during a Valsalva maneuver correlates with invasively measured left ventricular end-diastolic pressure (LVEDP). This key PPG ...

Conventional magnetic attitude control methodologies require several orbital periods to accomplish the required attitude maneuvers due to the existence of an uncontrollable axis, namely the local Earth’s magnetic field vector. Since in some attitude maneuver missions the elapsed time is of critical importance, those time-consuming controllers are not satisfactory and we need a much faster contr...

We sought to determine whether apnea-induced cardiovascular responses resulted in a biologically significant temporary O(2) conservation during exercise. Nine healthy men performing steady-state leg exercise carried out repeated apnea (A) and rebreathing (R) maneuvers starting with residual volume +3.5 liters of air. Heart rate (HR), mean arterial pressure (MAP), and arterial O(2) saturation (S...

BACKGROUND The duration of postinspiratory pause prior to forced expiration may significantly influence the peak expiratory flow (PEF) measured during maximal forceful expirations. In comparison with maneuvers without a postinspiratory pause, maneuvers with 4 to 6-s pause at total lung capacity (TLC) result in decreased PEF values. The extent to which brief pauses (< 2 s) similarly affect PEF v...

Background: With improved perioperative care and improvement in surgical techniques have led to excellent outcomes following major liver resections. Inflow occlusion is selectively used these days. However, at our center, we routinely use Pringle‘s Maneuver during This study done analyze the outcome of resections with routine Pringle’s Maneuver. Method: Retrospective review medical records pati...
