account for the changes that occur throughout a case. The indirect method
looks at physiological parameters such as blood pressure and heart rate data
and uses an algorithm to predict LOP. The direct method entails sticking a
sensor right at the cuff to see if there's occlusion. If it's not occluded, the
technology increases the pressure. Once the pressure is high enough, the sen-
sor can tell that it's
occluded and there's no
need to look at the other
physiological measures.
The end goal is the same
for both: maintain LOP
throughout the proce-
dure to ensure the safest
care possible for
patients.

No two people are the same. Treating
every patient with precise, personalized
care is the inspiration behind our
market-leading Tourniquet
System design. That's why the
Zimmer Tourniquet Systems
don't just stop blood flow. Our
tourniquet systems can deliver
Personalized Pressure – the minimum
amount of tourniquet pressure for each
individual patient.
