There may be a short pause while the device performs a pre-measurement
check. The device will then begin inflating the cuff. During this time the status
area will display Measuring Blood Pressure and the current cuff pressure will be
displayed.

If your model of BP+ supports “Measurement on Inflation”, the device will attempt
to determine the systolic, mean and diastolic pressures and pulse rate as the cuff
is inflated. If the model does not support measurement on inflation, or the device
is unable to determine the blood pressure during inflation, once the pre-set target
pressure is reached, the device will gradually deflate the cuff at a controlled rate
of approximately 3 mmHg/s. During this time, the device will attempt to
determine the systolic, mean and diastolic pressures, as well as pulse rate as the
cuff is deflated. If the initial inflation pressure is less than the systolic pressure,
the device will re-inflate the cuff to a higher pressure before the controlled
deflation. If the BP+ does not successfully measure the subject’s blood pressure,
selecting a higher or lower inflation target may help.
If your model of BP+ supports “Measurement on Inflation”, and it successfully
determines the blood pressure during inflation, the device will directly inflate the
cuff to the suprasystolic pulse wave pressure. Otherwise, once the blood
pressure and pulse rate has been determined by deflating the cuff, the device will
re-inflate the cuff to the suprasystolic pressure (approximately 30 mmHg above
the measured systolic pressure). This suprasystolic pulse wave pressure will be
maintained for around 12 seconds. During this time, the status area will display
Measuring Pulse Wave. After the pulse wave measurement is finished, the cuff
pressure will be completely released. This marks the completion of the entire
measurement cycle. The BP+ will then process the acquired data and display
the result on the screen.
