The Predictive Value of Infant-Specific Preoperative Pulmonary Function Tests in Postoperative Pulmonary Complications in Infants with Congenital Heart Diseases

Table 3

Relationship between preoperative pulmonary function tests (with normal range) and postoperative pulmonary complications.

Groups	PPC	Non-PPC	OR (95% CI)	value	PPV	NPV
Respiratory rate	19 (17)	103 (41)	12.9 (2.8, 58.6)	<0.01	89.5%	60.2%
TPTEF/TE	19 (16)	103 (32)	11.8 (3.2, 43.5)	<0.01	84.2%	68.9%
VPEF/VE	19 (16)	103 (35)	10.4 (2.8, 38.0)	<0.01	84.2%	66.0%
Lung compliance	19 (15)	103 (27)	10.6 (3.2, 34.6)	<0.01	79.0%	73.8%

Fisher’s exact test for all comparisons. Numbers in brackets represent abnormal cases. PPC: preoperative pulmonary function; PPV: positive predictive value; NPV: negative predictive value.
