In COPD, rescue inhalers can be _______, _______, or __________ combo
SABAs, SAMAs, or SABA/SAMA
Why should supplemental oxygen be used with caution in patients with COPD?
While humans usually have a hypercapnic respiratory drive, chronic hypercapnia in COPDers desensitizes the body and they switch to a hypoxic respiratory drive. Therefore, too much oxygen can depress respiratory drive in COPD patients
