Non-invasive continuous-wave Doppler system for measuring blood flow, stroke volume and cardiac output.

USCOM 1A uses transcutaneous continuous-wave Doppler to measure blood flow through the aortic or pulmonary valve. The 2.2 MHz divergent beam transducer supports signal acquisition, while the touchscreen displays live data, stored data and hemodynamic trends.
The system displays 24 hemodynamic parameters. Seven values—CVP, systolic blood pressure, diastolic blood pressure, SpO2, Hb, height and weight—are entered by the user; DO2 and SVS parameters require the OXYCOM option.
