Functional residual capacity (FRC) was measured in 12 postoperative patients and in one preoperative patient before and after they received intermittent positive pressure breathing (IPPB) with room air for ten minutes at a peak delivered pressure of 15 cm H2O. Ten patients had a normal or low pretreatment FRC. After cessation of IPPB, the mean FRC decreased further. Arterial oxygen tensions, measured in 11 of the 13 patients, decreased in all 11 from a pretreatment mean of 67.8 +/- 4.3 mm Hg to an immediate posttreatment mean of 57.7 +/- 4.2 mm Hg. In five patients repeated arterial blood gases were measured. At 30 minutes, their arterial oxygen tensions had returned to the pre-IPPB values. This study demonstrates that the routine use of IPPB in postoperative patients accentuates preexisting hypoxia and, therefore, must be used with caution.
