Selecting The Correct Cu
Using the correct cu size is important for an accurate reading.
If the cu is not the proper size, the reading may yield an incorrect blood pressure
value.
The arm size is printed on each cu.
The index and proper t range, on the cu, tell you if you are attaching the
correct cu. (Refer to "Attaching The Arm Cu" below.)
If the index points outside of the range, contact your local dealer to purchase
a replacement cu
What is an irregular heartbeat
Sendo Economy provides a blood pressure and pulse rate measurement even
when an irregular heartbeat occurs. An irregular heartbeat is dened as a
heartbeat that varies by 25% from the average of all heartbeats during the blood
pressure measurement. It is important that you be relaxed, remain still and do not
talk during measurements.

indicator frequently.
