PIC Cardio Simple Blood Pressure Monitor

To check the blood pressure manually, sit in a relaxed position with the arm at rest on a table.
Secure the cuff on the bicep and squeeze the balloon to increase the pressure.
Watch the aneroid monitor and increase the pressure to about 30 mm Hg over the normal blood pressure, or to 180 mm Hg if this is not known.
When the cuff is inflated, place the stethoscope just inside the elbow crease under the cuff.
Slowly deflate the balloon and listen through the stethoscope.
When the first beats hit, note the number on the aneroid monitor.
This is the systolic pressure.
Continue listening until the steady heartbeat sound stops and record the number from the aneroid monitor again.
This is the diastolic pressure.
These two numbers are the blood pressure reading.
