Passive Leg Raise Technique

The passive leg raising (PLR) test measures the haemodynamic effects of a leg elevation up to 45°. This represents a

"self-volume challenge" and it is hypothesized that the changes in aortic blood flow induced by PLR can predict fluid

responsiveness in ventilated patients. This might be useful when the respiratory variation of arterial pulse pressure cannot

be used for that purpose (e.g. with arrhythmias and spontaneous breathing activity).

Numerous studies have concluded the benefit of the PLR as a method of determining fluid status, such as the 2011 article

by Marik, Monnet and Teboul (ref. 6 listed over). The NICOM features a step by step in-built PLR protocol which makes it

easy to gain a simple and fast indication of the patient’s fluid responsiveness.

Enhanced Recovery & Fluid Optimisation

The CHEETAH NICOM provides a swift (within two minutes) and simple collation of haemodynamic and cardiac output

measurements in any clinical area in the hospital. Pre-op monitoring removes the guesswork from managing the fluid

status of patients post-operatively, enhancing patient comfort and decreasing recovery times. Discharge from hospital

may be possible days earlier, saving huge sums from already stretched hospital budgets and allowing more patients to be

seen.

Passive Leg Raising

“Evidence now seems clear that clinical management and out-

comes can be improved by guided volume optimisation. My

pragmatic goal is to achieve this using a truly non-invasive

technique that minimises observer bias.

My experience with Bioreactance technology has demonstrated

to me its advantage over Doppler methods that do not facilitate

the straightforward continuation of measurement after surgery

in the recovery room and beyond.”
