Effectiveness of CPAP by mask for pulmonary edema associated with hypercarbia

Intensive Care Med. 1983;9(1):17-9. doi: 10.1007/BF01693700.


We describe continuous positive airway pressure (CPAP) by mask to reduce hypercarbia in two patients who had pulmonary edema due to congestive heart failure. In such patients, beside reducing venous return and filling pressures, CPAP improves compliance and decreases the work of breathing, thereby improving effective ventilation. Hence, CPAP may be useful to combat not only hypoxemia but also hypercarbia that is associated with pulmonary edema.
