How to calibrate omega 1445 bp monitor

My first question is how do you know it's not accurate? I would tee in a digital manometer (measure in mmHg), wrap the cuff around a glass bottle and let the cuff inflate. When it fully inflates the cuff...look at the readings between the monitor and your manometer. If they are within a few digits of one another, I would leave it alone.

Inaccuracies with patient nibp readings are usually related to improper cuff placement on the patient. There's usually a mark on the cuff to indicate where the cuff should be placed in relation to the brachial artery. I believe this unit utilizes oscillatory technology to determine readings and an improperly placed cuff can create inaccurate readings.
