I have a Microlife upper arm and a Microlife wrist monitor. Why do I get different results?
• Both devices have a comparable accuracy and follow the same principle. However, as each human has individual blood vessel and tissue constitution, one of the two different positions may have advantages for some individuals. • It is very important that the cuff be positioned at heart level during measurement. This is more difficult at the wrist and may lead to wrong results. 10 cm higher than heart means an under estimation by 8 mmHg while 10 cm below heard level means that the reading will be 8 mmHg too high! • It is possible that the signals of some individuals are very weak at the wrist due to their artery wall constitution. These people may get frequent error messages. • Arteries at the wrist are positioned very near to the surface, so the body signals are less covered by tissue than at the upper arm, this may lead to better readings at wrist than upper arm. • People with obese arms may face problems with upper arm cuffs, but get better results at the wrist. • Measurements at wris
