[Maximal oxygen consumption and decompensated metabolic acidosis threshold in the assessment of functional reserves of oxygen transport in cardiosurgical patients].
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.
