Echocardiographic determination of mean pulmonary artery pressure

The American Journal of Cardiology, 2003
We 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.

Noninvasive automatic determination of mean arterial pressure

Medical and Biological Engineering and Computing, 1979
A 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.

Radial Mean Arterial Pressure Reliably Reflects Femoral Mean Arterial Pressure in Uncomplicated Pediatric Cardiac Surgery

Journal of Cardiothoracic and Vascular Anesthesia, 2014
To see if radial mean arterial pressure reliably reflects femoral mean arterial pressure in uncomplicated pediatric cardiac surgery.An ethics committee-approved prospective interventional study.Operating room of a tertiary care hospital.Forty-five children aged 3 months to 4 years who underwent pediatric cardiac surgery with hypothermic cardiopulmonary

Mean arterial pressure and mean perfusion pressure deficit in septic acute kidney injury

Journal of Critical Care, 2015
Changes in mean perfusion pressure (MPP) from premorbid resting values may contribute to the progression of septic acute kidney injury (AKI).In patients with septic shock, we aimed to investigate the association of changes from premorbid values with AKI severity and progression.We obtained premorbid resting mean arterial pressure (MAP), central venous ...

Mean Arterial Pressure

2012
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 is all you need in a machine learning model for mean arterial pressure prediction

European Journal of Anaesthesiology
BACKGROUND Anaesthesiology and intensive care use monitoring to identify patients in danger of deterioration. Traditionally, trends and early warning scores allow clinicians to predict deterioration with moderate reliability. Reduced mean arterial blood pressure has been associated with complications, and models

Mean arterial pressure and average blood pressure

Proceedings of the 1988 Fourteenth Annual Northeast Bioengineering Conference, 2003
Mean 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.

The Effects of Air Bubble on Damping of Arterial Pressure Waves during Monitoring of Mean Arterial Pressure Waves during Monitoring of Mean Arterial Pressure

Korean Journal of Anesthesiology, 1982
By virtue of the development of monitoring system and increasing tendency of critically iN patients, We have performed canautation of radial artery after Allen`s test for the continuous monitoring of arterial pressure. It is very important to measure blood pressure accurated, as it gives as many information in the poor risk patients.

A Simple Device for the Direct Measurement of Mean Arterial Pressure and for Calibration of Arterial Pressure Monitors

Journal of Medical Engineering & Technology, 1986
A simple, inexpensive mechanical device is described for the direct continuous measurement of mean arterial pressure. It can be assembled in minutes using a few dollars worth of sterile components commonly available in an intensive care unit. Mean arterial pressure determined in patients with this device differs by 1.6 mmHg +/- 1.1 SD from mean ...

Changes in mean blood pressure caused by damping of the arterial pressure waveform

Early Human Development, 1994
'Damping' of an intra-arterial pressure waveform theoretically affects systolic and diastolic blood pressure whilst mean blood pressure (mbp) continues to be reliable. We assessed changes in mbp associated with 79 episodes of damping in 30 infants. The average mbp in the hour just before damping occurred was compared with that in the first hour of ...
