Mankind lives, works, and plays within an extensive range of high- and low-pressure environments. It is important to understand how altitude affects atmospheric pressure and subsequent alveolar oxygen availability. In addition to pressure-related cha

Cardiopulmonary resuscitation: effect of CPAP on gas exchange during chest compressions

Autor: Z G, Hevesi, D N, Thrush, J B, Downs, R A, Smith

Publikováno v: Anesthesiology. 90(4)

Conventional cardiopulmonary resuscitation (CPR) includes 80-100/min precordial compressions with intermittent positive pressure ventilation (IPPV) after every fifth compression. To prevent gastric insufflation, chest compressions are held during IPP

Intermittent CPAP: a new mode of ventilation during general anesthesia

Autor: E, Bratzke, J B, Downs, R A, Smith

Publikováno v: Anesthesiology. 89(2)

Airway pressure-release ventilation provides ventilation comparable to controlled mechanical ventilation (CMV), but with lower peak airway pressures and less dead-space ventilation. To obtain these advantages for patients administered general anesthe

Effect of endogenous and inhaled nitric oxide on the ventilation-perfusion relationships in oleic-acid lung injury

Autor: J B Downs, Christian Putensen, Jukka Räsänen

Publikováno v: American journal of respiratory and critical care medicine. 150(2)

Previous investigations have shown that the ventilation-perfusion (VA/Q) mismatch caused by acute lung injury can be alleviated either by inducing vasodilation in ventilated lung units with inhaled nitric oxide (NO) or by inhibiting the synthesis of

Direct or modified Seldinger guide wire-directed technique for arterial catheter insertion

Autor: D, Mangar, D N, Thrush, G R, Connell, J B, Downs

Publikováno v: Anesthesia and analgesia. 76(4)

Percutaneous radial artery cannulation is widely used for direct continuous arterial blood pressure measurement and sampling of arterial blood. We compared the success rate of arterial catheter placement in patients undergoing aortocoronary bypass op

Monitoring Cardiopulmonary Function with Dual Oximetry

Autor: J. B. Downs

Publikováno v: Anesthesia and the Lung 1992 ISBN: 9789401052085

“Assessment” of oxygenation may entail measurement and calculation of a variety of physiologic variables. However, the oxygen tension of arterial blood (P a02) is by far the most common measurement utilized in determining the of “adequacy” of

New Modes of Ventilatory Support

Autor: J. B. Downs

Publikováno v: Anesthesia and the Lung 1992 ISBN: 9789401052085

Since the advent of intermittent positive pressure ventilation (IPPV), positive end-expiratory pressure (PEEP), intermittent mandatory ventilation (IMV), continuous positive airway press ure (CPAP), mandatory minute ventilation (MMV), and high freque
