CVP tracing

- a wave is first upstroke following p wave on ECG
- a wave: atrium contraction
- c wave: closure of TV
- v wave: filling of atrium with closed TV
- CVP is assessed at base of c wave
- If c wave is not seen, then mean of peak and trough of a wave is used
- in spontaneously breathing patient: read from peak (lowest intrathoracic pressure point = highest level)
- vented patient: read from trough (highest intrathoracic pressure) Not sure if this logic is correct 1
