Normal adult P/F ratio (On RA)

400 or greater
CPAP

continuous positive airway pressure. Pt determines volume and rate, but
cont. pressure keeps airways open.
SIMV
,Give this one a try later!
Synchronized intermittent mechanical ventilation. Theres a set VT and rate,
but all spontaneous breaths above the rate are at the pt's own VT.
How does PEEP affect surface tension and intrapulmonary shunt?
Give this one a try later!
It decreases surface tension and intrapulmonary shunt.

VILI
Give this one a try later!
Ventilator-Induced Lung Injury. Alveolar over-distention due to high peak
inflation volume (volutrauma) produces acute lung injury
P/F ratio
Give this one a try later!
P = PaO2
F = FiO2
P divided by F is the P/F ratio. It determines then ratio between oxygen
delivery and the actual arterial concentration of oxygen.
