Most Accurate Results

When Using the Max Pulse In Research Studies: When doing trials that require perfectly repeatable tests, you have to be very careful to follow the test instructions exactly. Follow the wait period after coffee, the no smoking before the test, and the person must have an empty stomach and the hands must be warm.

The empty stomach is important. When a person eats, the body constricts the arteries at the periphery to push blood into the body core. Then the body will tighten and loosen arteries continuously to maintain the optimum core blood levels for digestion. Tests taken while digesting will fluctuate because of this. The length of time after eating is important but different foods digest at different speeds so its also important that the person reports that they have an empty stomach.

A. Back to Back Testing: If you are testing several times, one after another, you must follow the testing instructions precisely. That means you test the subject on an empty stomach, no caffeine or nicotine for at least 2 hours, with the patient having warm hands (use hand warmer) and the patient sitting comfortably and normally (no closing eyes, no special breathing, nothing except sitting comfortably). The clip must be on the left index finger with the hand approximately at heart level. So to get a very tight and accurate result you have to follow all the instructions here – https://longlifecardio.com/max-pulse/max-pulse-test-guide/. Any violations of the rules and the tests get sloppy and they move around a bit.
B. When tests move around: Tests move around a little bit when they are not done exactly per the instructions. To understand the movement you have to have a really clear understanding of the 2 types of scoring that are going on.
4 and 6 are arterial hardening. So a person who scores 60% Type 4 and 40% Type 6 is showing arterial hardening – some heartbeats reflecting severe, some heartbeats reflecting moderate. These percentages can shift around fluctuating between 4 and 6 if the person is digesting food, or agitated or any of the other things in the setup.
3 and 5 are heart weakening. So a persons score might move between a 3 and a 5 but its the same situation, just showing at different weakness. Type 3 is barely detectable heart weakening – Type 5 is noticable heart weakening. Again this can move around some if the test is not done per instructions.
C.  Arrhythmia: Sometimes you can do a test perfectly and the test results are still not steady. The thing to check is to make sure the patient does not have an arrhythmia If a patient has an irregular heartbeat, you can get an invalid test. You can see this when you do the 3 minute HRV test – that test scores the number of ectopic (irregular) heartbeats. If you do a test and are careful to do everything right and the results are not fairly steady, then run the HRV and see how many ectopic beats there are. Those beats are going to throw everything off. People who drink a lot of coffee often have a lot of ectopic beats. Other stimulants, drugs, medications can do the same thing. You have to get the person off the stimulants before you can get a steady reading.
D.Quick Testing: Often medical practices are using the machine as a screening tool, trying to find severe problems. They should be testing on a mostly empty stomach, still no caffiene for 2 hours, no smoking directly before the test, warm hands etc but they don’t have to be so exacting. Tests will be less accurate. Once a person is detected with a severe problem – 5, 6 or 7. They should carefully re-test before referring the patient out.
