Requirement Demonstration 1:
+/- 5% Blood Volume Measurement Accuracy
653mL * (0.05) = 32.65��653 +/- 32.65 = 620.35, 685.45
620.35 < 634 <685.45
*653 not 652
Requirement Demonstration 2:
Alarm Activation Within < 3 Seconds
Requirement Demonstration 3:
Pause Alarm Sound Within < 3 Seconds of Button Press
