pressure (NIBP) measurement methods, such as doppler ultrasound (DOP) and pulse oximeter plethysmography (POP), may be used as alternatives to IBP measurement. Systolic arterial blood pressure (SAP) measurements from the forelimb and hindlimb using DOP in

hemodynamics of the vasculature supplying patients’ femoral heads. 11 Various techniques have been used in human medicine to assess the morphology and hemodynamics of the femoral head vasculature, and of these, Doppler ultrasonography is a noninvasive

Pulsed Doppler echocardiography is used to noninvasively assess ventricular diastolic dysfunction. However, PD-derived variables including TMF velocity, deceleration time, and IRT can be affected by several factors, such as heart rate and loading

-mode ultrasonography is commonly used in small animal practice and generates a grayscale image based on the amplitude and depth of returning echoes. 10 Doppler ultrasonography identifies an apparent shift in the sound frequency of a moving target within an imaged area

depends on the clinical class of the disease (ie, ISACHC classification 14 ). We also undertook to determine the correlation between pulmonary arterial pressure and certain Doppler echocardiographic indices that reflect the severity of valvular disease (eg

purpose of this study was to determine reference values for echocardiographic M-mode and Doppler measurements in clinically healthy rabbits that were lightly anesthetized with ketamine and medetomidine. Materials and Methods The study was performed

Doppler echocardiography is used to noninvasively assess ventricular diastolic dysfunction. Previously, we reported that PD-derived tricuspid flow profiles reflect inotropic agent–induced diastolic function in dogs. 1 Dobutamine evokes an

Tissue Doppler imaging is increasingly used in veterinary cardiology to evaluate LV function. Tissue Doppler imaging allows quantification of systolic and diastolic myocardial velocities on the basis of the Doppler principle. Conventional color
