driving pressure

1. In respiratory physiology, the difference between the inspiratory pressure and the expiratory pressure.
2. In cardiovascular physiology, the difference between the arterial pressure at the source of blood flow, and the pressure at the target tissue.

Limiting the driving pressure to 1 inch WC allowed a viable cell recovery of >80%, whereas 5 inch WC driving pressure reduced viable recovery to below 50%, and 10 inch WC pressure effectively prohibited any viable cell capture (Fig.
To quantify proliferability, 10 GFP-expressing C8161 cells were spiked into 1 mL of peripheral blood and passed through a 5-[micro]m gap width FMSA at 5 inch WC driving pressure.
For laminar flow the resistance is very low and it is evident that a relatively small driving pressure is able to produce a significant resultant flow rate.
Turbulent flow results in a relatively larger airway resistance when compared with laminar flow and a much larger driving pressure is required to produce the same flow rate.
The collective impedance is an impediment to flow and if impedance increases a higher driving pressure may be required to negate its dampening effects.
and driving pressures from 40 to 90 cm H2O may need to be employed to achieve CO2 clearance.
Banks worldwide are currently facing driving pressures to reduce costs, increase the straight through processing (STP) rate of payment transactions, and improve customer service while also meeting regulatory compliance mandates.
After several decades of steadily mounting evidence, we have become quite aware that high airway pressures coupled with high airway driving pressures (end-inspiratory minus end expiratory static airway pressure) may inflict ventilator induced lung injury (VILI).
BOSTON -- Enterprises ranked financial results and improved operational efficiencies as among the strongest driving pressures behind their decisions to automate access to information, says Aberdeen Report.
