Ventilation tests, which measure the capacity of the lungs to move air in and out, include maximal voluntary ventilation (MVV), maximal air volume expelled in 12 15 seconds of forced breathing; forced expiratory volume (FEV), maximum air volume expelled in a time interval; and maximal expiratory flow rate (MEFR), maximal flow rate of a single expelled breath, expressed in litres of air per minute.
Thus, at the maximal flow rate, the pressure drop was only 0.025 torr while the temperature gradient along the catalytic unit axial section was only 0.8 °C/cm.
The 3-F inner dilators from three brands of micropuncture kits with slightly different designs were studied to identify the maximal flow rate of contrast medium infusion in hopes of identifying a safe range for the delivery of contrast media.
Using the tool, it is also shown that, the ozonation channel of Vivaqua can be used to achieve degradation of resistant microorganisms but only with its maximal flow rate and concentration of ozone injection.
When all the outlets are open, the standard flow rate deviation changes from 0.050 to 0.069 and the maximal flow rate ratio, i.e. the ratio of the highest flow rate to the lowest, changes from 1.170 to 1.252 when the averaged Re at the outlet increases from 1020 to 2247.
The test results demonstrate that the frequency-dependent pumping flow rate shows consistent trend under these various operational parameters, and a maximal flow rate of 34 μL/min is achieved at the driving frequency of 3 Hz and applied pressure of 25 kPa.
Contrast medium was administered over a minimum of 20 sec at a maximal flow rate of 3 mL/sec.
Early subjective functional results (maximal flow rate, IPSS, and post-void residual urine) appeared the same as those obtained following laser prostatectomy.
Among the three groups, there were no significant differences in maximal flow rate, lower post-void residual urine, and postoperative PSA level during the entire follow-up period (P<0.05).
