Question

Which of the following is not a global criteria for extubation?

1) Normothermia
2) Head lift for more than 5 seconds
3) Hgb 7
4) pH 7.48

Answer 1

A blood pH of 7.48, indicating a state of alkalosis, is not a criterion that would prevent extubation. Extubation readiness includes normothermia, sufficient muscle strength, and acceptable hemoglobin levels.

Step-by-step explanation:

When considering global criteria for extubation, various physiological parameters must be evaluated to ensure that a patient is ready to be removed from mechanical ventilation safely. Among the criteria listed, normothermia, ability to perform a head lift for more than 5 seconds, and an acceptable range of hemoglobin levels (Hgb 7) are typically considered. However, a blood pH of 7.48 does not preclude extubation; it indicates a state of alkalosis rather than acidosis and can still be compatible with successful extubation if other clinical signs support the patient's readiness.
