Minimum Pressure Measurement Range 20 mmHg. Feel the pulse of the artery with your finger tips and inflate the cuff after closing the air flow value on the bulb. Keep listening to the beat. When you can no longer here the beat, raise the pressure by additional 22-30 mm.Maximum Pressure Measurement Range 300 mmHg. Deflate the cuff slowly so that the pressure drops while 2-4 mm/sec. The moment you hear the sound of the pulse beat note the reading of the gauge. This is your systolic blood pressure.
