Possibilities of assessing the functional reserves in the oxygen transport system (OTS) were studied in cardiosurgical patients by spiro-ergometrically determining the maximal oxygen consumption (VO2 max) and decompensated metabolic acidotic threshold (DMAT). Seventy seven patients (53 males and 24 females) with various cardiac diseases were examined. A low incidence of an oxygen consumption "plateau" was found, which limited the determination of VO2 max in the cardiosurgical setting. DMAT occurred at a level of 76.0 +/- 11.6% of VO2 max and closely correlated (r = 0.86; p less than 0.05). It was concluded that it was advisable to additionally study the prospects for applying DMAT to the assessment of OTS functional reserves in cardiosurgical patients.
通过螺旋测力计法测定最大耗氧量（VO2 max）和失代偿性代谢性酸中毒阈值（DMAT），研究了心脏外科手术患者评估氧运输系统（OTS）功能储备的可能性。对77例患有各种心脏病的患者（53例男性和24例女性）进行了检查。发现耗氧量“平台期”的发生率较低，这限制了在心脏外科手术环境中对VO2 max的测定。DMAT出现在VO2 max的76.0 +/- 11.6%水平，且相关性密切（r = 0.86；p < 0.05）。得出结论，建议进一步研究将DMAT应用于评估心脏外科手术患者OTS功能储备的前景。
