Aplicação de Dois Métodos de Calibração da Plestimografia Respiratória por Indutância em Duas Posturas Diferentes

摘要

The purpose of this study was to assess two methods of calibration of Respiratory Inductive Plethysmography (RIP), isovolume (ISOCAL) and qualitative diagnostic calibration (QDC), in two-body positions (sitting and standing). Twenty-three normal subjects (15 females, 8 males) aged 25,4 ± 3,9 (mean ± standard deviation) years were monitored. The results indicated that the calibration factor (K) is significantly different between both calibration methods. The K mean values, and standard deviation, corresponding to ISOCAL and QDC were 2,6 ± 0,8 and 0,7 ± 0,2 for standing position, and 2,0 ± 0,8 and 0,6 ± 0,2 for sitting position, respectively. We obtained K values in ISOCAL calibration compatible to physiological understanding of the body positions applied.
