title: [Relations between stress intensity, sex and ergometric procedures in healthy probands and patients with obstructive respiratory diseases].
abstract: In 223 healthy people and patients with obstructive lung diseases we examined the degree of cardiopulmonary exhaustion during two ergometric stress tests (Ergooxytensiometrie [EOT] and submaximal Ergostasetest [ET]). Main purpose of the study was to look for differences between sexes in the degree of exhaustion in relation to the type of stress test, thus clarifying the need of a special EOT-modification for women. Measured parameters were arterial oxygen pressure (pO2a), arterial carbon dioxide pressure (pCO2a), base excess (BE), heart rate, noninvasive blood pressure, Wmax and in ET additionally oxygen intake (VO2max) and oxygen pulse. In EOT men and women showed similar results regarding pressure frequence product in health people as well as in patients. Heart rate in EOT was also similar for men and women clearly below maximal range, amounting around 70% of age related maximal value. For pO2a as main indicator of pulmonary gas exchange we found no differences in healthy people as well as in patients with obstructive lung disease between both ergometric methods, but generally some what higher values in women without clinical importance. A sex related modification of the EOT for the evidence of hypoxemia is not necessary.
