Clinical trials: Stroke Volume Index
Hemorrhage
Comparison of Compensatory Reserve Index to Intravascular Volume Change and Stroke Volume
This study is designed to validate implementation of the CRI algorithm in the CypherOx CRI system. Healthy human subjects will undergo progressive reduction in central blood volume to the point of hemodynamic instability (defined…
