Flashcards in Hemodynamic Monitoring Deck (20)
Normal PA pressures are (mmHg)
Right atrial pressure
Pulmonary artery pressure reflects
Right and left side heart pressures
PA wedge pressure reflects
Preload of the left atrium
Normal range for cardiac output is
Normal range for PAWP is
Normal range for CVP is
Cardiac output is determined by
Heart Rate * Stroke Volume
Afterload of the left side of the heart
Pulmonary vascular resistance measures
Afterload of the right side of the heart
The dichrotic notch indicates
Closure of a valve (aortic or pulmonic)
A decrease in CVP may indicate
Decreased venous return
An increase in CVP may indicate
Right side heart failure
A decrease in SVR may indicate
Distributive Shock (neurogenic, anaphylactic, septic)
An increase in SVR may indicate
Cardiogenic or Hypovolemic Shock
The "a" wave in a CVP waveform indicates __ and corresponds to what part of the ECG?
Rise in atrial pressure as a result of atrial contraction, corresponds with the PR interval
The "c" wave in a CVP waveform indicates __ and corresponds to what part of the ECG?
Rise in atrial pressure when AV valve closes, corresponds with mid/late QRS
The "v" wave in a CVP waveform indicates __ and corresponds to what part of the ECG?
Rise in atrial pressure as a result of ventricular contraction, corresponds with mid T wave
The "x descent" in a CVP waveform indicates __ and is seen where?
Atrial relaxation, the downslope of the "a" wave
