Occurrence of ARF, was identified when PaO2 was < 60 mmHg with FiO2 = 0.21. Outcome failure was defined as needs of invasive mechanical ventilation (IMV) and/or death. We also evaluated the relationship between duration of ARF and P/F and STP/F. Recovery from ARF occurred before ...
During 60 sec apnoea in air f card fell to 46% of control. It was concluded that in response to the present levels of hypercapnia and hypoxia, t increases less in spontaneously breathing pigeons and chickens than it does in ducks. The primary effect of hypercapnic hypoxia on heart rate of...

Clinical Problem 5-5.For each of the four conditions below, give the expected changes (increased, decreased, or normal) for PaO2, SaO2and CaO2. Assume the subject is breathing ambient air, that each situation occurred acutely (in less than 24 hours), and that there is no other abnormal ...
and unfortunately, we have not been able to compensate for respiratory fluctuations. We do believe, however, that our data do not deviate much from the true result, as the pressure swings are less important at rest compared with during exercise where they are augmented by dynamic hyperinflation....
Our aims in this study were to report changes in the ratio of alveolar dead space to tidal volume (VDalv/VT) in the prone position (PP) and to test whether changes in partial pressure of arterial CO2 (PaCO2) may be more relevant than changes in the ratio of partial pressure of arterial...

Computed P/F ratio less than 297.6 had 89.7% sensitivity and 82% specificity for the diagnosis of P/F ratio less than 300. Conclusion PtcCO2 has a significant influence on the prediction of P/F ratio from S/F ratio. Prospective studies with more patients are needed to validate these ...
