Question

Normal guidelines for infant ventilation is to keep the PaCO2 below _____ torr and the PaO2 above ______ torr.

a) PaCO2 below 40 torr, PaO2 above 60 torr
b) PaCO2 below 45 torr, PaO2 above 70 torr
c) PaCO2 below 50 torr, PaO2 above 80 torr [b - PaCO2 below 45 torr, PaO2 above 70 torr]
d) PaCO2 below 35 torr, PaO2 above 50 torr

Answer 1

The normal guidelines for infant ventilation are to keep PaCO2 below 45 torr and PaO2 above 70 torr. Hence the correct answer is option B

Step-by-step explanation:

The normal guidelines for infant ventilation aim to maintain certain values for PaCO2 (partial pressure of carbon dioxide) and PaO2 (partial pressure of oxygen) in the blood. According to the options provided, the correct guideline is to keep PaCO2 below 45 torr and PaO2 above 70 torr. This means that the carbon dioxide levels should be below 45 torr, while the oxygen levels should be above 70 torr in order to ensure proper ventilation in infants.

Hence the correct answer is option B
