Paper Abstract

Near infrared spectroscopy (NIRS) was used to measure oxygen consumption (VO2) in the human forearm with two different methods.VO2 was measured in ten patients, first by inducing a forearm venous occlusion and then an ischemia. The mean value of VO2 was 3.3 ± 1.1 μMO2 × 100 g-1×min-1 during venous occlusion and 2.9±0.9 μMO2 × 100 g-1×min-1 during ischemia. The difference between the two means was 0.4 μMO2 × 100 g-1×min-1. A good agreement between the two methods was demonstrated. The results showed that NIRS is a useful tool for the measurement of VO2. The venous occlusion method was the method of choice because it could be easily repeated at the bedside without causing any discomfort to the patient.
