JVP-ASK ME
|
*Manometer of right atrial pressure.
* Function at waveform points: ASK ME: • Atrial filling • Systole • Klosed tricuspid • Maximal atrial filling • Emptying of atrium * S1 occurs with 'a' and 'c' wave, S2 occur with 'v' wave. |
|
|
Distinguishing JVP from carotid
|
* Fills from above.
* Complex, double pulsation for each arterial pulse [if pt has normal sinus rhythm]. * Usually visible, but not palpable. * Changes with posture [decreases as sit up more vertical]. * Moves on inspiration [decreases in healthy]. * Hepatojugular reflux. |

|
Causes of elevated JVP
|
Too much fluid:
* Fluid overload [esp. IV infusion] It's clogging up before gets to heart: * SVC obstruction Can't beat it out of the heart fast enough: * RVF * Bradycardia * Constrictive pericarditis * Pericardial effusion * Tricuspid stenosis or regurgitation Other: * Hyperdynamic circulation |
