Abstract

A position levelling apparatus having an sensor (10) which is adapted to be located at a position spaced from a required position and an levelling unit (11) which is adapted to be located remote from the sensor which can receive, from the sensor, parameters relating to the required position so that changes in the location of the required position can be ascertained. Blood pressure levelling unit transducers (14) are located at predetermined location on the levelling unit and the levelling unit displays the height above or below the level of the tricuspid valve that tranducers are located. The levelling unit having means (17) whereby it can be moved up or down so that the transducers can be maintained at a height corresponding to that of the tricuspid valve whereby the readings of the transducers are not modified by any variation in vertical location between themselves and the tricuspid valve. Instead of moving the unit, it can provide an adjustment factor for the transducers or an associated monitor (12) as though the transducers were at the level of the tricuspid valve.
