Implication

Pulsatility index may indicate peripheral resistance in animal models; leaves open translation to human echocardiography.

Structured PICO

P
Population
3 anesthetized pigs
I
Intervention
Combined 3.5-MHz real-time and 2-MHz pulsed-Doppler ultrasound recording of blood flow velocity waveforms in the abdominal aorta
C
Comparator
Electromagnetic flowmeter measurement of volume blood flow, mean arterial pressure, and calculated total peripheral resistance
O
Outcome
Correlation between Doppler-derived waveform parameters (pulsatility index, systolic to diastolic ratio, minimum diastolic velocity) and total peripheral resistancesurrogate

In an animal model, the pulsatility index derived from Doppler ultrasound is a good linear indicator of changes in peripheral vascular resistance.
