Zeroing
10
opposition
encountered by LEFT ventricle
Pulmonary Vascular Resistance (PVR)
Systematic Vascular Resistance (SVR)
11
If hand does not return to pinkness w/in 6 secs it is okay to insert because the ulnar artery circulation is adequate
True
False
12
Body surface Area is more precise measuremnt of efficiency of <3 pumping action(left& right ventricle pump at same time)
False
True
13
Checking equipment reproduces w/o distorted signal. Perform every 8-12hrs when system open to air (start flash flush)
Arterial BP

Maintaing Arterial BP Line Patency & Limit Thrombus Formation:
System delivering continous slow (1-3mL/hr flush
Flush bag contains fluid
Assess every 1-4hrs
Pressure bag inflated 300 mmHg

Preload Increases
25
Safety Alert: Positioning the Zero Reference Stopcock
Transducers HIGHER THAN PT produce a LOW BP
Recheck lvling of zero refernece stopcock to PA w/any change in pt position
Mark location of phelobostatic axis on pt chest w/permanent marker
Transducers LOWER THAN PT produce a HIGH BP
