Converts pressure signal to an electronic signal?
Transducer
20
Y downslope reflects?
Ventricular relaxation
21
Central venous insertion site?
Subclavian or internal jugular vein
22
___________ may also lead to a higher pulse pressure because a slow heart rate allows the blood volume more time for diastolic runoff and causes a lower diastolic pressure.
