Of the mechanical parameters, both compliance and resistance during exercise showed a significant relation to WC (p<0.001), as indicated by a multiple orthogonal regression analysis. The Pa02 at rest showed no significant correlation to WC, and Pa02 at work only a weak correlation (Table 2). birth control yasmin
Relation Between Arterial Blood Gases and Other Physiologic Parameters
The PaOz at rest in the sitting position showed weak significant correlations to, eg, FEV, (r = 0.43, p<0.001) and VC (r = 0.36, p<0.01). Somewhat stronger correlations were seen between Pa02 at maximal work and, eg, FEV, (Table 2). A multiple orthogonal regression analysis between Pa02 at maximal work (dependent variable) and CdynL and RfL, also at maximal work, (independent variables) revealed a significant correlation only to CdynL. No patient had, as single abnormality in the resting and exercise findings, an abnormally reduced Pa02 at maximal exercise.
Relation Between Mechanical Parameters at Exercise and Physiologic Findings at Rest
The CdynL at maximal work correlated significantly to CstL (r = 0.63, p<0.001) and to CdynL at rest (r = 0.57, p<0.001). Some correlation was also seen between dynamic and static resting measurements (r = 0.64, p<0.001).
