LifeSource manual ? HOW UA-774 Works, Before YOU Start, Selecting the Correct Cuff Size

?HOW UA-774 WORKS

LifeSource™ Blood Pressure Monitors are easy to use, accurate and digitally display full measurement readouts. Our technology is based on the “oscillometric method” — a noninvasive blood pressure determination. The term “oscillation” refers to any 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 page E-11 for using the Monitor with AC Adapter) and attach the cuff to the monitor before using it. 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 forward.	-	+	-	+

2. Put in top row of batteries first. Place the OPEN

batteries in compartment with positive

(+) and negative (–) terminals matching

those indicated in the compartment. Be sure batteries make contact with compartment terminals.

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

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#
5.1” - 7.9” (13-20cm)	Small Cuff	UA-279
7.5” - 12.2” (19-31cm)	Medium Cuff	UA-280
7.5” - 14.2” (19-36cm)	Medium EasyCuff™	UA-380
11.8” - 17.7” (30-45cm)	Large Cuff	UA-281

To attach cuff, insert air connector at end of cuff tube into the air socket on the left side of the monitor.

Cuff Size Indicator On The Cuff

Our cuff has an indicator which tells you whether you are using the correct cuff size or not. Place the cuff on your arm (see Page E-7 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 size. 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 at an additional cost.
