Lower-Body Limb Occlusion Pressure – LOP Device (V1.1)

🖇 This is a follow-up to the recent Post (August 24, 2022) presenting the LOP Device (V1.1).

📺 This time around we look at how to measure lower-body Limb Occlusion Pressure (LOP) with the Leg Cuff V3.1, as it can be a bit tricky compared to upper-body assessments.

🚫 If you have no interest in the product or have already been through the guide at fitcuffs.com/lop the content below might not be for you. But if you´re struggling with Leg LOP’s check at least section 7!?

1. Make sure the cuff is completely deflated.

2. Wear the Leg Cuff tight before inflation and please remember not to sit on it.

3. Position yourself or your client as displayed, resting the foot on the floor with a straight or slight bend knee.

4. Sit still – even the slightest movement or subtle muscle contraction/twitch can interfere with the calculation and make it impossible for the device to detect LOP.

5. Inflate to about 280 mmHg before you let the LOP Device deflate.

6. Before the cuff has been deflated below 230 mmHg, adjust the valve on the pressure gauge to slightly increase the rate of deflation. Only the very peak of the green pulse waves is accepted outside the app display.

🔄 7. An alternative method is displayed in the video. As you can also adjust the pressure gauge just a tiny bit, but before inflating the cuff, again for accelerating the rate at which air is released.

💡 A correct deflation rate is characterized by only the very peak of the pulse waves being out of bounds. As a rule of thumb aim for a deflation time of 20-50 seconds from 250 mmHg to 110 mmHg. But when the device has deflated below 230 mmHg, please remember not to adjust any further as this will interfere with the measurement.

⚠️ Disclaimer: When assessing conventional blood pressure (BP), you should always use a calibrated cuff in terms of size. The ideal cuff should have a bladder length that is 80% of the arm circumference, a width that is at least 40% of the arm circumference, and a length-to-width ratio of 2:1. That is why you cannot use Fit Cuffs product selection to measure BP.
