Rossmax Fingertip Pulse Oximeter with ACT

Accurate to a Point but expensive – This is the third Oximeter I have reviewed but it was not cheap. I wanted to find out what the ACT does, and does it work, and I wanted Bluetooth. The unit comes in a large box with batteries and a lanyard. I tested this against an OMRON HEM 7600T blood pressure monitor and a Creative medical PC-60F oximeter. The first thing you notice about the unit is it has a skirt; the idea is to stop stray light entering the unit. it also has a stop/start button, some of the others don't you just stick your finger in it. It also has a soft rubbery feeling to the inside; most others are just hard plastic. When I checked my pulse, I thought there was something wrong, it took about 30 seconds to settle on a measurement my Sp02 level was ok, but my pulse came in at around 42-45 beats. I then checked this against the other machines, and they all agreed with about 2-3 BPM and the SpO2 level was with 1-2 units of each other. I could not see why my pulse was low this morning, I had gone out, walked a bit, drove my car, had some coffee, had no chest pain, was not dizzy, so I printed out the info after taking it a number of times and I will show my doctor next visit. The ACT started out giving me a 2 then it went up to a 3 and then a 4, after retesting a number of times the reading was either 3 or 4 so I guess my artery condition is between the 2. But what I believe is happening is this, it takes a measurement by somehow bouncing light off your artery, but it's hit and miss, Then, it applies some algorithm in a data base, which takes into account your SpO2 level and your pulse, then it spits out a result. The reason I say this is because I saw a variation depending on my pulse reading, this morning it was a 2 I went out, did shopping, took it again, and it was 4. But not so good. I reckon if it had been 5 or 6 I would have passed this info on to my doctor, but I am not sure what you can do when your arteries have hardened and this device, when it comes to the ACT is not that accurate. . The unit is a worthwhile addition to home health care and having an app where you can print out results is a bonus, but paying extra for the ACT is a big no from me.

It's not cheap, but you get what you pay for.
