Question

Respiratory criteria for extubation - adequate ventilation - PaCO2

Option 1: Elevated PaCO2 levels
Option 2: Normal PaCO2 levels
Option 3: Increased respiratory rate
Option 4: Decreased tidal volume

Answer 1

Respiratory criteria for extubation involves assessing the level of carbon dioxide (PaCO2) to determine adequate ventilation. Elevated PaCO2 levels suggest inadequate ventilation, while normal levels indicate sufficient ventilation.

Step-by-step explanation:

In respiratory criteria for extubation, adequate ventilation is important. One of the factors that needs to be considered is the level of carbon dioxide (PaCO2) in the blood. Elevated PaCO2 levels indicate inadequate ventilation, while normal PaCO2 levels indicate sufficient ventilation.

Option 1: Elevated PaCO2 levels - This would be a criterion for not extubating as it suggests insufficient ventilation.

Option 2: Normal PaCO2 levels - This would be a criterion for extubation as it indicates adequate ventilation.

Option 3: Increased respiratory rate - This may be indicative of increased effort to maintain ventilation, but it does not necessarily guarantee adequate ventilation.

Option 4: Decreased tidal volume - This would be a criterion for not extubating as it suggests inadequate ventilation.
