When compared to that with intermittent positivepressure ventilation, ventilation using external high frequency oscillation increased pulmonary blood flow by 116 + 61.5% (p=0.013).
The duration of the sampling period was chosen to equal one ventilator cycle to "average" the effects of positivepressure ventilation.
Since the prevailing wind is also from the south-west, this approach avoids the potential problem of positivepressure on exhaust air vents.
In one patient, complete atelectasis of both upper lobes occurred just after dilation and could be managed by manual positivepressure ventilation.
Heavy-ion-induced hydrodynamic motion in lead targets the simulation, an expansion wave with negative pressures propagates through the target behind the positivepressure pulse.
In particular, one man's work3 anticipated intermittent positivepressure ventilation, cardiac and respiratory pacemakers and variations upon the theme of circulatory assist devices.
Six patients were on a positivepressure ventilation at the time of surgery because of congestive heart failure and respiratory infections due to syncytial virus.
In this circumstance, he documented restoration of blood flow to the lungs and, when combined with oxygenation (from positivepressure ventilation), he generated brief signs of reanimation.
In one patient, however, extreme anteflexion of the probe caused transient airway obstruction both during intermittent positivepressure ventilation, and during ventilation by means of the oscillator.
Hydropneumopericardium is a very rare condition which may occur after trauma, pericarditis caused by gas-forming organisms, fistulas, or medical procedures such as positivepressure ventilation or endoscopy.
It would apply positivepressure to try to achieve a freer, more democratic and sounder world.
