ALPK2 Mercurial Sphygmomanometer consists of an inflatable cuff, a measuring unit (mercury manometer), and a mechanism for inflation manually operated bulb and valve. It is usually used in conjunction with a stethoscope. This blood pressure monitor is enclosed in an aluminum die cast body.
Connect one tube from the bladder to air release valve and bulb. Connect the other bladder tube to the manometer.
Wrap cuff around upper left arm and adhere Velcro together. Be sure to position arrow on cuff over the brachial artery.
Place chest piece of stethoscope (not included) under the edge of the cuff where arrow is pointing.
While holding bulb, turn know on air release valve clockwise and pump bulb until point rises to approximately 40 points above the subjects average systolic pressure. Deflate cuff slowly (about 2 to 4 points per second) by turning the knob counter-clockwise.
At the point where the first beat is heard, record the reading from the mercury gauge. This is the systolic pressure.
Continue deflating the cuff while listening to the pulse beat. When the pulse beat is no longer heard record the reading from the mercury gauge. This is the diastolic pressure.
