Reduced blood volume leads to collapsing vessels, reduced pressure, and subsequently reduced perfusion pressure. The cardiovascular system combats low blood volume by constricting blood vessels until the body reaches a blood pressure that restores proper perfusion pressure.
Confirmatory Tests vary, and may be wrong from time to time. As time passes, the test is not as reliable as stated. If the so called "blood" is on a leather surface, blood isn't too prone to sticking to leather, so it may (or may not) be blood.
They should volunteer for meds sorry if i’m wrong
The action the nurse should take after deflating the balloon tip following pressure measurement is to deflate the balloon as soon as the PAWP is measured.
<h3>
What is pulmonary artery wedge pressure (PAWP)?</h3>
The pulmonary wedge pressure(PAWP) also called pulmonary arterial wedge pressure, pulmonary capillary wedge pressure, pulmonary artery occlusion pressure, or cross-sectional pressure, is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.
Although the balloon must be inflated to measure the PAWP, it is deflated as soon as the PAWP is obtained to allow blood to continue to flow through the pulmonary artery.
