Patients with chronic obstructive pulmonary disease (COPD), who usually have chronic hypercarbia (high CO2) and mild to moderate hypoxemia, may benefit from this device.
* Administration of high oxygen concentrations to patients with COPD may produce respiratory depression because the increase in PaO2 eliminates the stimulant effect of hypoxemia on the respiratory centers.
* Never withhold oxygen from patients who have respiratory distress and severe hypoxemia simply because you suspect a hypoxic ventilatory drive.
Unrecognized and uncorrected intubation of a bronchus can result in hypoxemia due to underinflation of the uninvolved lung or overinflation of the ventilated lung.
