Echocardiographic determination of mean pulmonary artery pressure
The American Journal of Cardiology, 2003We performed a simultaneous Doppler and invasive study to validate the role of Doppler-derived peak pulmonary regurgitant velocity as a reliable noninvasive measure of pulmonary artery mean pressure. Assessment of right atrial pressure, as shown in this study, enhances the use of this Doppler parameter as a correlate of pulmonary artery mean pressure.

New Formula for Predicting Mean Pulmonary Artery Pressure Using Systolic Pulmonary Artery Pressure
Chest, 2004Mean pulmonary artery pressure (MPAP) and systolic pulmonary artery pressure (SPAP) are used interchangeably to define pulmonary hypertension (PH). We tested the hypothesis that the measurement of MPAP and SPAP is redundant in resting humans over a wide pressure range.Prospective, observational study.Catheterization laboratory in a university hospital ...

Mean arterial pressure and average blood pressure
Proceedings of the 1988 Fourteenth Annual Northeast Bioengineering Conference, 2003Mean arterial pressure (MAP) and average blood pressure (ABP) are compared. MAP is normally computed as some weighted mean of systolic and diastolic pressures. Average blood pressure is defined here as the area under the pressure pulse contour divided by the duration of the heart cycle.

Let us consider the cardiovascular system as a simple hydraulic circuit, where there is a pump (heart) with a rhythmic activity (systole → diastole → systole …) that pushes a liquid (blood) into a tube (aorta), which divides over and over again (peripheral arteries → arterioles → capillaries) to be able to reach the farthest extremes (tissues).

Mean Arterial Pressure: Therapeutic Goals and Pharmacologic Support
Critical Care Clinics, 2010The Surviving Sepsis Campaign targets central venous pressure, mean arterial pressure, and central venous oxygen saturation as guides for resuscitation. Fluid resuscitation and the use of vasopressors are paramount to the success of the campaign's end points. Although the achievement of supranormal physiologic parameters has been associated with higher

Indirect mean arterial pressure in the anesthetized dog
American Journal of Physiology-Heart and Circulatory Physiology, 1980Using the oscillometric method, indirect mean arterial pressure was measured in 14 pentobarbital-anesthetized dogs (8-24 kg) with mean arterial pressure ranging from 23 to 160 mmHg. The effect of cuff size, in relation to forelimb circumference was investigated.

Noninvasive automatic determination of mean arterial pressure
Medical and Biological Engineering and Computing, 1979A new instrument for the indirect noninvasive measurement of mean arterial pressure (m.a.p.) has been constructed and evaluated in man. The instrument does not require an external microphone or transducer and determines m.a.p. rather than systolic and diastolic pressure. Instead, the method employs the point of maximal oscillations as an indicator of m.

Abstract P86: Predicting Mean Pulmonary Arterial Pressure Using Systemic Arterial Pressure (SPAP)
Circulation: Cardiovascular Quality and Outcomes, 2011Background: The assessment of pulmonary pressure is elementary in the management of patients with pulmonary hypertension. Presently, pulmonary artery systolic pressure (PASP) can be reliably estimated using non-invasive means, but mean pulmonary pressure (MPAP) cannot be derived. The aim of this study was to derive a formula to
