Aortic heart disease is a condition affecting the aortic valve, one of four valves in the heart. Most aortic valve problems are related to stenosis, when the valve becomes rigid an unable to open properly, or regurgitation, when the valve leaflets

Flow Resistance of Exhalation Valves and Positive End

We studied the flow-impeding characteristics of the exhalation valves and PEEP attachments commonly used in mechanical ventilation. To characterize these devices, the pressure difference across each mechanism was measured at a series of constant flows (5 to 160 L/min), and resistance-related energy dissipation was measured using mechanical models of passive and active exhalation.

Results. The mean R filter for the 29.4 PR was significantly lower than the other 2 PRs (p < 0.000), but there were no significant differences in mean R filter between the PRs with 58.8 and 88.2 Pa filter resistance (p > 0.05). The mean R filter was greater for oral versus nasal breathing and for exercise compared to sedentary activity (p < 0.001).
