were derived from a sample of 20 R-waves at 0 and ÿ60mmHg levels of LBNP during the last minute of each stage. Results: The use of LBNP resulted in a significant reduction in central blood volume as indicated by decreases in SV from 125 G 9 to 43 G 6 ml (p\.001) and SBP from 129 G 3 to 111 G 6 mmHg (p=.005) and elevation in HR from 57 G 3 to 89 G 5 (p\.001). Despite significant reduction in central blood volume, R-wave amplitude at -60 mmHg LBNP (0.95G0.15) did not differ (P = 0.26) from baseline (0.94 G 0.15). Conclusion: Significant reduction of central blood volume by LBNP in humans is not associated with variations in R-wave amplitude. Our data do not support the use of the R-wave amplitude as an early predictor of hypovolemia.
