These give the Parkinsonâs patient a typical mask-like face. There is an interesting reciprocal relationship between Parkinsonâs and Alzheimerâs disease, as follows: Late in Parkinsonâs disease symptoms of dementia develop in perhaps fifteen percent of such patients.
The pulmonary artery vent is a plastic sump catheter that is introduced into the main pulmonary artery through a purse-string suture and connected via a roller pump to the venous reservoir of the heart-lung perfusion machine.Placement and removal require only a few minutes.ata relating to the hemodynamic efficaciousness and mechanism of action of a pulmonary artery catheter or vent used for left ventricular venting during cardiac operations are presented.
How does the structure of arteries and veins relate to their functions? Arteries - transports oxygenated blood from the heart (except in pulmonary artery which contains deoxygenated blood). Arteries have: -thick muscular wall. -much elastic tissue. -small lumen relative to diameter. -not permeable. -valves in pulmonary artery and Aorta only. -blood under high pressure (10-16kPa)
