Systolic blood pressure was obtained by non-invasive method using the Doppler flowmeter and the oscillometric method. 48 animals were excluded due to the high variability of values, with systolic blood pressure greater than 160 mm.Hg, as well as uncooperative and/or aggressive patients. There was...

Oscillotonometry: A simple non‐invasive method of differentiating proximal arterial obstruction from distal microangiopathy in the vascular assessment of ... .Doppler pressure measurement is of assistance but there is a significant subgroup who have proximal obstruction despite the findings of a high ...
Purpose The optimal method for blood pressure (BP) measurement among pts implanted with HeartMate 3 (HM3), a centrifugal pump that features an artificial pulse, is presently unknown. We aimed to: 1) assess success rate and validity of Doppler opening BP (DOBP) and automated BP (ABP) monito...
The sensitivity of the model in predicting the change in external pressure from the change in zero flow pressure was 94%. This indicates that estimation of zero flow pressure by this method is a sensitive way of monitoring trends in changes in downstream pressure. 展开 ...

Doppler ultrasonography- application of the Doppler effect in ultrasound to detect movement of scatterers (usually red blood cells) by the analysis of the change in frequency of the returning echoes. Doppler ultrasound flowmeter Doppler ultrasound segmental blood pressure testing ...
Indirectly, it can also measure the CBF and the intracranial pressure. This review describes briefly the method of using the equipment and the various indices that can be measured. The applications of TCD are varied. The review also gives an account of the various clinical situations where TCD ...
摘要: This paper reports a novel method for representing the spectrum of pulsed Doppler ultrasound blood flow signals. It is an alternative to the time-frequency estimation method, that maintains the information contained in the time signal using a minimum computational cost solution....
