alveolar pressure

Alveolar pressure remains at 0, plus or minus 2 cm H2O throughout the lung.

Blood vessels are completely collapsed by alveolar pressure and blood does not flow through these regions.

The alveolar pressure is estimated by measuring the pressure in the airways while holding one's breath.

Pressure from the arterial side builds up until it exceeds alveolar pressure and flow resumes.

Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs.

In normal health pulmonary arterial pressure exceeds alveolar pressure in all parts of the lung.

Plateau pressure is monitored as a surrogate for end-inspiratory alveolar pressure, and may help to minimize lung injury.

High PEEP necessarily increases mean airway pressure and alveolar pressure.

This accumulation of air increases alveolar pressure at the end of expiration, which is referred to as auto-PEEP.

Alveolar pressure (P) is the pressure in centimeters of water pressure (cmH2O) held within the alveoli of the lungs during inspiration.

This combination of small tidal volumes delivered for very short periods of time creates the lowest possible distal airway and alveolar pressures produced by a mechanical ventilator.

It is quite likely that there is a portion of the lung toward the top in an upright subject in which the pressure in the pulmonary arteries is less than alveolar pressure."

Under physiological conditions the transpulmonary pressure is always positive; intrapleural pressure is always negative and relatively large, while alveolar pressure moves from slightly positive to slightly negative as a person breathes.

If giving pure oxygen at 100% for five-ten minutes doesn't raise the arterial pressure of O2 more than it does the alveolar pressure of O2 then the defect in the lung is because of a pulmonary shunt.

Other achievements include the first description of persistent fetal circulation syndrome, the development of continuous positive alveolar pressure (CPAP) as a treatment for premature infants, the creation of the Apgar score and the performance of the world's first pediatric heart transplant.
