A meta‐analysis of the accuracy and precision of the ultrasonic cardiac output monitor (USCOM)
Tóm tắt
The ultrasonic cardiac output monitor is a non‐invasive, continuous‐wave Doppler monitor that can be used to measure cardiac output. Its accuracy and precision in peri‐operative and critical care has been assessed with varied results. We conducted a meta‐analysis to calculate a pooled mean bias, precision and percentage error for this device. Six studies were suitable for inclusion into a pooled parametric analysis consisting of 320 measurements. The mean weighted bias was −0.39 l.min−1(95% CI −0.25 to −0.53 l.min−1), precision 1.27 l.min−1and percentage error 42.7% (95% CI 38.5−46.9%). The ultrasonic cardiac output monitor achieved similar agreement with bolus thermodilution to that of other minimally invasive methods of peri‐operative cardiac output monitoring, and may have a useful role in cardiac output monitoring.
