c)   Tighten the free end of the cuff and close the cuff 

with the closer.

d)   There must be no free space between the arm and 

the cuff as this would influence the result. Clothing 
must not restrict the arm. Any piece of clothing which 
does (e.g. a pullover) must be taken off.

e)   Secure the cuff with the closer in such a way that it lies 

comfortably and is not too tight. Lay the arm on the table 
(palm upwards) so that the cuff is at the same height as 
the heart. Make sure that the tube is not kinked.

f)   Remain seated quietly for 2 minutes before you begin 

the measurement.

Comment:

If it is not possible to fit the cuff to the left arm, it can also be 
placed on the right one. However all measurements should be 
made using the same arm.

4.4. Measuring procedure
4.4.1. Put the chest piece under the cuff 

The chest piece shall not be placed ON or INTO the cuff, it shall be 
placed either under the cuff, or 1 - 2 cm below it. The chest piece 
is then placed correctly , when the Korrot koff’s sound appears 
strongest (‘loudest’). Make sure the chest piece is in contact with 
skin and above the brachial artery. Wear the binaural (ear pieces) 
properly to check the Korotkoff’s sound during measurement.
Before using the stethoscope, be sure there is no crack on the 
diaphragm, ear pieces, and tubing. Any improper setup or damage 
of the stethoscope will cause distorted sound or poor sound 
transmission to make inaccurate reading.
