Abstract
Embodiments of the present invention provide for maintaining a level set of a pulmonary artery catheterization apparatus that includes a pulmonary artery pressure sensor in communication with a pulmonary artery catherization manifold affixed to a pulmonary artery catheter. The method includes calibrating leveling of the pulmonary artery pressure sensor (at the level of the right atrium) with the pulmonary artery catheterization manifold by recording a vertical level of a leveling base positioned at a common level to the manifold, relative to a vertical level of a leveling sensor positioned at a common level to the pulmonary artery pressure sensor. The method further includes monitoring a difference between the recorded vertical level of the leveling base relative to the vertical level of the leveling sensor. Finally, the method includes generating an alert in a user interface element of the leveling sensor in response to the monitored difference exceeding a threshold value.
