Why the study?
Is the phlebostatic axis a valid external reference point for intracardiac pressure measurements in supine and lateral positions?
Is the phlebostatic axis a valid external reference point for intracardiac pressure measurements in supine and lateral positions?
The phlebostatic axis is a valid reference point for intracardiac pressure measurements in the supine position, but not in lateral positions, indicating pressure measurements in lateral positions may be inaccurate.
No takes yet. Share an insight, caveat, or question.
Caution advised for lateral-position intracardiac pressures; leaves open prospective validation of alternative references.
Kee et al. (1993) studied this question.
