Cardiogenic or Hypovolemic Shock

16
Q

The “a” wave in a CVP waveform indicates __ and corresponds to what part of the ECG?

A

Rise in atrial pressure as a result of atrial contraction, corresponds with the PR interval

17
Q

The “c” wave in a CVP waveform indicates __ and corresponds to what part of the ECG?

A

Rise in atrial pressure when AV valve closes, corresponds with mid/late QRS

18
Q

The “v” wave in a CVP waveform indicates __ and corresponds to what part of the ECG?

A

Rise in atrial pressure as a result of ventricular contraction, corresponds with mid T wave

19
Q

The “x descent” in a CVP waveform indicates __ and is seen where?

A

Atrial relaxation, the downslope of the “a” wave

20
Q

The “y descent” in a CVP waveform indicates __ and is seen where?

A

Atrial emptying, the downslope of the “v” wave
