I was a little worried there would be considerable set up, but once I put the batteries in the device, it immediately started doing its job. The batteries, btw, are supplied by the manufacturer.
Pulse oximeter, when compared to those conventional pulse rate checking devices, is so much more active and detect any irregularities in one is pulse rates within no time. they can keep these at home or office, even healthcare consultants are now buying that device to track pulse rates. On top of it, the device is pocket friendly too.
I looked at 'them all.' As a retired healthcare worker I couldn't ask for a more smooth and attractive yet multifunctional design assist. This was a gift to a family of 5 including 2 yo twins and a 5 yo. With the rail on, the 3 siblings were able to have their first bath all together without danger of falling during "wild wiggling water babies. You would NEVER look at this rail and think oh they use a "medical device...." It even matches the shower curtain!
