متن کاملDiminished Forearm Arteriolar Dilator Capacity
The mechanism of the increased stiffness of peripheral vessels in patients with congestive heart failure (CHF) is unknown. It was considered that an increased sodium (Na+) content of peripheral vessels, shown in experimental CHF, might lead to diminished arteriolar dilator capacity. Thus, Na+ retention was induced in six normal volunteers by the daily oral administration of 0.2 mg of fludrocort...
متن کاملThe Cardio-Pneumatic Movements
When the heart begins to contract, blood will be flowing into the chest as before, but the systolic pulse will not have reached the vessels at their outlets from the chest. The total result will therefore be that at this instant more blood will be within the chest than was the case before the commencement of systole, and in consequence of this air will leave the chest. As soon, however, as the ...
متن کاملThe pneumatic practice pad
The Pneumatic Practice Pad is a commercially available 10” practice pad that has been modified to allow for tension changes in a matter of seconds using a small electric air pump. In this paper, we examine the rebound characteristics of the Pneumatic Practice Pad at various pressure presets and compare them to a sample of acoustic drums. We also review subjective feedback from participants in a...
متن کاملVessel dilator cricothyrotomy for transtracheal jet ventilation.
Needle cricothyrotomy is a safe, relatively easy procedure and has been described to enable pulmonary ventilation for patients in both elective and emergency situations. Conventional IV cannulae are short, thin-walled, and easily kinked and, therefore, do not provide a secure system to jet oxygen into the trachea. The vessel dilators of most 7-9 French introducer kits are firm, pliable, resist ...
