We use our non-invasive jugular venous pressure (JVP) assessment to measure right atrial pressure (RAP). Generally, a normal RAP is < 6 mmHg (via cath) or < 8 cm H2O (via exam).
Methods for assessment:
- Seated at 90˚ (Source)
- JVP elevated if can be seen above the clavicle
- ± abdominojugular reflux testing
- Clavicles are ≈ 12-16 cm above the mid-RA
- Seated at 30-45˚
- JVP elevated if > 8 cm
- Add or remove pillows PRN to relax SCM
- Add 5 cm from the sternal angle (angle of Louis)
- Turns out that the actual distance from the sternal angle to the level of the mid-right atrium varies considerably b/w pts and based on pt position.
- Anthem Sign (Source) - hand veins
Differentiating aortic vs. venous pulsations
Look at the IJ from a tangential perspective, i.e. not perpendicularly.
