TABLE 4.

Filter criteria. Blood pressures refer to those taken in the brachial artery, and the reflection coefficient was calculated at the aorto-iliac bifurcation using Eq. 4 (Willemet et al., 2015b).

Criterion	Range	Group
Stroke Volume	60–100 ml	Controls
	<60 ml	Patients
Cardiac Output	4–8 L/min	Controls
Diastolic Blood Pressure	≥40 mmHg	All
Systolic Blood Pressure	≤200 mmHg	All
Pulse Pressure, P pulse	25 mmHg ≤ Ppulse ≤ 100 mmHg	All
Reflection Coefficient, R a	−0.3 ≤ R a ≤ 0.3	All
