Human Physiology Laboratory: Cardiovascular

PhysioFlow^TM

captures continuous non-invasive measurements of several hemodynamic parameters both at rest and during exercise. Measurements may include cardiac output/ index, heart rate, stroke volume, contractility index, early diastolic filling ratio (indicator of preload), ejection fraction and end diastolic volume (estimates), blood pressure profile (SAP, DAP, MAP), systemic vascular resistance/index and left cardiac work index.

EKG

The Marquette MAC 5000 ECG system used to monitor patients' heart rhythm, and to evaluate the effects of exercise another variables on heart function.

Ultrasound

The MicroMaxx Ultrasound System is capable of obtaining images of cardiac and vascular structures as well as measurements of blood flow in blood vessels and in the heart. It is used in the HPL to assess cardiovascular changes in response to exercise or stressors.

Monitoring equipment

Several small medical devices are used to monitor subjects during both exercise and research procedures for safety purposes. These include Polar heart rate monitors, blood pressure monitoring devices, Pulse Oximeter and Pulse CO-Oximeter.
