Brian, a 58-year-old patient, is noted to have a decreased lung compliance during his pulmonary function tests. What does this suggest about the physiology of his respiration?
Diffusion of gases will be enhanced
Pulmonary blood supply is compromised
Ventilation is likely efficient
Work of breathing will be increased
The Correct Answer is D
A. Decreased lung compliance doesn't directly enhance gas diffusion; it may impair it due to decreased lung expansion.
B. Decreased lung compliance doesn't necessarily indicate compromised pulmonary blood supply; it's more related to the lung's ability to expand and contract.
C. Decreased lung compliance suggests that ventilation may be impaired because the lungs are less able to expand and contract effectively.
D. Decreased lung compliance means the lungs are stiffer, requiring more effort to breathe, thus increasing the work of breathing.

Correct Answer is B
Explanation
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.
