Radial artery waveforms were recorded from the wrist of the dominant arm with a high-fidelity micromanometer
(SPC-301; Millar Instruments).
Pressure sensors were calibrated with a Druck DPI605 and a micromanometer
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
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 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.
The piezometer rings were connected to a micromanometer
by means of the aforementioned tubing in order to measure the pressure drop across the test section.
At each station, pressure readings of five-hole probe and wall static pressure are recorded from digital micromanometer
connected via the 20 channel scanning box.
As individual bubbles formed and were released, the maximum pressure (assumed equal to the ambient pressure at the tip opening) was measured using a micromanometer
(Furness Controls FCO14), and repeated at 5 mm intervals up the column.
The heart was exposed via median sternotomy and a 3-French combined micromanometer
pressure and dual-field conductance catheter (SPR-855, Millar Instruments, Texas, U.
used for pressure control was designed specifically for CVD gas use.
For example, Photo 2 shows a duct leakage test-out value that is below the range of the micromanometer
used to monitor the progress of duct sealing during installation.
The pressure was monitored by a differential pressure micromanometer
based on the pressure drop in the system with an accuracy of 0.
