CONTEC ABPM50 Handheld 24hours Ambulatory Blood Stress Monitor with PC Software program for Steady Monitoring NIBP USB Port with Three Cuffs

I wish the manufacturer would contact me, and updated review
I need a 24hr blood pressure monitor, because I have supine high blood pressure. I bought this device, despite the reviews that said the instructions were difficult.I should have hit “pause” on that thought.The instructions are not difficult, they are obtuse, badly translated, and downright comical. “This cuff is consumable” is just a sample.There is no way to turn on the ambulatory function, and see that it is working. I waited 30 minutes for a measurement that never came.If I could get this to work, I will change my review. I set a message to the manufacturer, and this is day 3 of no response.Anyone else have suggestions?Update!!I finally got it to work, and I’m wearing it now. I have a full night’s list of readings, and will have a full day by tonight. The secret is that there are TWO ABP menu items, and y ou must choose the right one, and then highlight it (make it turn red), and then choose “begin”.And, as I realized during the night, the Awake feature is not the time you wake up, but the time the monitor starts checking, so use awake and sleep as the start and stop features.I have changed my star rating to 5.

A great device and software for a self-learner; really TERRIBLE instructions.
The device provides quite accurate and reproducible data, but the instructions are woeful. The package is not ready for prime time. It badly needs full instructions written by a native English speaker; readily accessible software (presently only found by devious search paths); and BP cuffs with D-loops that allow self-application (surely anyone using the device would want the ability to take the cuff off and put it back on alone, at least to allow for a shower). First, some basics. ABPM should really stand for “Automatic” blood pressure monitor, not “Ambulatory”. None of these devices, by this maker or any other, can measure the BP while you are ambulating. In fact, once the cuff inflation begins, you must stop moving the arm and allow it to hang motionless until the cuff deflates. Otherwise, the measurement will fail and an annoying alarm will begin. Also, be aware that BP is always varying, and sometimes greatly, depending on your mental and physical activities. The purpose of these devices it to look for trends: what happens during sleep, or exercise, or as a medication takes effect, etc. Used this way, the results can be very valuable. The first accompanying figure shows ten readings taken roughly 2 minutes apart on both arms at the same time — one using this device, and one using another maker’s cuff and device. This device inflates to above the systolic pressure, then measures during deflation; the other measures during inflation, and stops when the systolic signal disappears. Therefore, one method may be less “real” than the other (of course, both are approximations to the pressure actually existing in the artery). As the figure show, though, both are very consistent. The diastolic values are practically the same, and so are the pulse rates (not shown). The Contec device consistently reads the systolic pressure roughly 10mmHg lower than the other device. This is not necessarily wrong or bad; remember, it is trends that are important; and the error could be in the other device, too. [It was previously confirmed that the pressures in both arms were the same, so these comparisons reflect the device measurements and not the subject’s abnormalities]. The software is quite good, especially the reports for printing. There is considerable scope for editing data, setting limits and times, and programming the machine. The second figure shows 32 hours of data, just one page of the standard 5-page printed report. (Unfortunately the “night-time” shading is too dark and cannot be modified). The 3rd figure shows the same data in histogram format. Some brief comments: I have worn the device continuously for up to 32 hours, and several 24-hour sessions, and it performs as desired — no better nor worse than other similar machines. I did purchase a separate BP cuff to allow self-application, and some new fitting for hoses to match (all available on Amazon), so I could shorten the very long hose supplied. Two AA batteries lasted for 4 or 5 days of recording. Note that the minimum interval between measurements is 15 minutes — not 5 minutes, as suggested in the descriptions supplied — but 15 minutes is as often as most would want anyway. The software works fine with Windows 10, but cannot be reduced to less than full screen when in use (annoying, but not a serious problem as it does its work very quickly and then can be closed). All in all: the builders made a good device, but the marketers have a lot of work to do to make it user-friendly.

Measure all the time
When I measure most of the time even without removing a sleeve I do 3x times and all 3 times it shows random numbers lol I’m not sure if it’s a good brand

Does not work
Today is the first day I opened the product at first it was working and all of the sudden it just went all black change batteries and it does not turn on.

There is no CD &Batteries are POOR as a result I am unable to start the machine yet.There is no process in Amazon to contact the seller for resolving my issue.

I love the machine but there was no software to connect it to my computer to do printouts. Finally found download site contecmed.com and file is PM10. Figured this out after downloading two files that have nothing to do with monitor. Would have given 5 stars but for trouble with software. Company needs to hire good English translator to write instructions and description of software.
