reversed with higher flows of supplemental 02' Potential respiratory

depression should never contraindicate oxygen therapy in severe

hypoxemia, however. If hypoventilation is a major problem, other

support measures, including mechanical ventilation, can be used.1

Significant supplemental 0, requirements usually indicate a

respiratOry compromise, which in turn may indicate the need to

modify or defer physical therapy intervention.


Observe the patient for clinical signs of hypoxemia: shorrness of

breath, use of accessory muscles of breathing, confusion, pallor, or

cyanosis.
