We all know the gold standard for confirmation of a CVP catheter is a chest x-ray. However, if that is not immediately available, has anyone heard of:
Confirmation via ECG?
Confirmation via doppler while injecting 10mL air?
I found some info discussing the use of premature beats on the ECG monitor to confirm CVP catheter placement. Didn't read too much about it but it seems study results varied, and the sensitivity of such a method would be low. It is however, possible it seems.
I could not find ANYTHING about confirmation via doppler while injecting air. Anyone know about this?
