Bronchial blood supply evaluation

Oximetry

Mixed venous blood gases

Pulmonary blood supply evaluation

Answer and Explanation

The Correct Answer is B

A.   Bronchial blood supply evaluation is not a direct method of monitoring oxygenation status.
B.   Oximetry measures oxygen saturation (SaO2) continuously and non-invasively, providing real-time information about oxygen levels in the blood, which is essential for monitoring a patient with COPD.

C.   Mixed venous blood gases provide information about oxygen extraction by tissues but are not commonly used for continuous monitoring of oxygenation status.
D.   Pulmonary blood supply evaluation may involve various imaging techniques or invasive procedures but is not used for continuous monitoring of oxygenation status.
