LifeSource manual ? HOW UA-787 Works, Before YOU Start, Selecting the Correct Cuff Size

?HOW UA-787 WORKS

LifeSourceTM blood pressure monitors are easy to use, accurate and digitally display full measurement readouts. Our technology is based on the “oscillometric method”—a non-invasive blood pressure determination. The term “oscillation” refers to the measure of vibrations caused by the arterial pulse. Our monitor examines the pulsatile pressure generated by the arterial wall as it expands and contracts against the cuff with each heartbeat.

The cuff is inflated until the artery is fully blocked. The inflation speed is maximized and the pressure level is optimized by the device. The monitor takes measurements while the cuff is both inflating and deflating. This results in a faster measurement providing greater comfort to the user.

BEFORE YOU START

You must install 4 type “AA” (1.5 volt) batteries, or use the AC adapter (see Pg. E-10 for Using the Monitor with AC Adapter), and attach the cuff to the monitor before using. To install batteries (or replace them if the “Low Battery” symbol appears on display), proceed as follows:

1.Remove battery compartment cover by gently pushing down on arrow and sliding cover down.

2. Put in top row of batteries first. Place

terminals.

3.Replace cover by sliding it into the compartment and gently pressing down.

SELECTING THE CORRECT CUFF SIZE

Using the correct cuff size is important for an accurate reading. A cuff that is too large will produce a reading that is lower than the correct blood pressure; a cuff that is too small will produce a reading that is higher than the correct blood pressure. With your arm hanging at the side of your body, measure the circumference of your upper arm at the midpoint between the shoulder and elbow.

ARM SIZE	RECOMMENDED	REPLACEMENT
	CUFF SIZE	CUFF MODEL#
7.5” - 14.2” (19-36cm)	EasyCuff ™ Feature**	UA-380
5.1” - 7.9” (13-20cm)	Small Cuff	UA-279
7.5” - 12.2” (19-31cm)	Medium Cuff	UA-280
11.8” - 17.7” (30-45cm)	Large Cuff	UA-281

**The EasyCuff feature is a semi-hard shell cuff which provides easy placement on your upper arm. The UA-787 comes with the EasyCuff feature. If arm circum- ference is greater than 14.2”(36 cm) or smaller than 7.5”(19 cm), you will need to purchase the proper size cuff to ensure correct measurement. If this is the case, please call A&D Medical at 1-888-726-9966 (in Canada - 1-800-463-5414).

Cuff Size Indicator On The Cuff

Our cuff has an indicator which tells you whether you are using the correct cuff or not. Place the cuff on your arm (see Pg. E-6 to learn how to put the cuff on correctly) and if the Index Mark ▲ points within the Proper Fit Range, you are using the correct cuff. If the Index points outside of the Proper Fit Range, contact A&D Medical at 1-888-726-9966 (in Canada - 1-800-463-5414) for a cuff replacement.
