Characterisation of the normal right ventricular pressure-volume relation by biplane angiography and simultaneous micromanometer pressure measurements.
The static gage pressure was measured at a location one duct diameter upstream of the test section by means of pressure taps configured as a piezometric ring and connected to a micromanometer using pressure tubing.
The flow dynamic pressure was measured with a Betz type 2500 micromanometer Acin, Van-Essen, associated with Pitot-Prandtl, with a resolution of 0.1 Pa and accuracy of the read-out of +/- 0.04%.
Radial artery waveforms were recorded from the wrist of the dominant arm with a high-fidelity micromanometer (SPC-301; Millar Instruments).
(17) To measure AIx, an ascending aortic pressure waveform was derived from the radial artery waveforms recorded at the wrist using applanation tonometry with a high-fidelity micromanometer. The aortic augmentation pressure (AP) was calculated as the difference between the first and second systolic peaks of the ascending aortic waveform, and AIx was expressed as a percentage of the central pulse pressure (the difference between the central systolic and diastolic pressures).
A 1.4-F high-fidelity micromanometer catheter (Millar Instruments, Houston, TX) was inserted into the LV through carotid artery under continuous hemodynamic monitoring to measure LV pressure, volume, and heart rate.
We used a high-fidelity SPC-301 micromanometer (Millar Instruments, Houston, TX) interfaced with a computer running SphygmoCor software, version 8.2 (AtCor Medical, West Ryde, New South Wales, Australia).
To measure the augmentation index (AIx), an ascending aortic pressure waveform was derived from the radial artery waveforms recorded at the wrist using applanation tonometry with a high-fidelity micromanometer. The aortic augmentation pressure was calculated as the difference between the first and second systolic peaks of the ascending aortic waveform, and AIx was expressed as a percentage of the central pulse pressure (the difference between the central systolic and diastolic pressures).
Digital micromanometer with a pressure scanner (make: Furness Controls, UK) is used to measure pressure, velocity when connected to a measuring instrument like pitot-static tube and wall-static pressure taps.
The Autonomous Micromanometer can be removed from the core unit and is capable of: Simultaneous display of airflow and temperature; Automatic airflow direction (extraction or air blast); Automatic averaging or point by point averaging; Hold function; and Data processing on computer with USB port.
