American Diagnostic Corporation (ADC) Diagnostix 932 - Manual (Page 3)

Your DIAGNOSTIX™ 932 consists of a main unit with 5mm calibrated unbreakable plastic cartridgetube, inflation
system (which includes the ADCUFF™ nylon cuff with Size Guide™ marking system, latex-free inflation bladder,
bulb, and ADFLOW™ valve), luer connector, and operating instructions. Unit is preassembled and ready for use.
Connecting the Inflation System to Manometer:
Remove red safety cap which seals the reservoir containing mercury. Attach the free end of reservoir tube securely
to air inlet. Save red safety cap for later use. When transporting mercury instrument we recommend placing the red
safety cap on reservoir.
Please Note: It is normal for negligible amounts of residual mercury droplets to accumulate around the air
inlet beneath the red safety cap during transportation.
Operating Instructions
Your DIAGNOSTIX™ 932 Desktop Mercury Sphygmomanometer incorporates a special safety feature that locks the mer-
cury within the reservoir during storage, transport, or maintenance.
To Operate the 932: To release the mercury from the reservoir, turn the lever to the “ON” position. Mercury will flow
up into the plastic cartridge tube and rest at the ”0” mark. If the mercury doesn’t rise within the tube tilt the entire unit
45° forward. If mercury fails to rise, or doesn’t reach the ”0” level, have unit serviced.
To Lock Mercury Within the Reservoir: Tilt the entire unit back 45° towards the reservoir to permit mercury to flow out of cartridge
tube and into reservoir. When cartridge tube is completely emptied of ALL mercury (and while it is still tilted 45°), move locking lever to the
right. Mercury should be locked within the reservoir during maintenance or transport.
PLEASE NOTE: MERCURY SHOULD BE SECURED WITHIN THE RESERVOIR DURING TRANSPORT, OR WHEN SERVICING
THE CARTRIDGE TUBE, DIAPHRAGMS, OR FILTERS. NEVER DISASSEMBLE UNIT UNLESS MERCURY IS FIRST LOCKED
WITHIN RESERVOIR.
Measurement Procedure
1. Patient Position
The patient should sit or lie comfortably. The arm should be fully supported on a flat surface at heart level. (If the arm’s position varies, or is
not level with the heart, measurement values obtained will not be consistent with the patient’s true blood pressure.) Observer should view
manometer in a direct line and at eye level to avoid “parallax error”.
2. Apply the Cuff
ADCUFF ™ nylon cuffs, with proprietary Size Guide ™ marking system, are specially de-
signed to promote the precise, accurate determination of blood pressure. Index and range
markings ensure use of the correct cuff size. The artery mark indicates proper cuff positioning.
Place the cuff over the bare upper arm with “artery” mark positioned directly over the
brachial artery. The bottom edge of the cuff should be positioned approximately one inch
above the antecubital fold. Wrap the end of the cuff, not containing the bladder, around
arm snugly and smoothly and engage adhesive strips. To verify a correct fit, check that
the INDEX line falls between the two RANGE lines.
3. Inflate the Cuff
Close the ADFLOW™ valve by turning thumbscrew clockwise. Palpate the radial artery while inflating the cuff. Be sure to inflate cuff
quickly by squeezing bulb rapidly. Inflate cuff 20-30mmHg above the point at which the radial pulse disappears.
4. Position the Stethoscope
Position the chestpiece in the antecubital space below the cuff, distal to the brachium. Do not place chestpiece underneath the cuff, as this
impedes accurate measurement. Use the bell side of a combination stethoscope for clearest detection of the low pitched Korotkoff (pulse)
sounds.
5. Deflate the Cuff
Open the valve to deflate the cuff gradually at the AHA recommended rate of 2-3mmHg per second.
6. Measurement
Record the onset of Korotkoff sounds (Phase 1) as the systolic pressure and the disappearance of these sounds (Phase 5) diastolic pressure.
(Some healthcare professionals prefer recording diastolic 1 and diastolic 2. Diastolic 1 occurs at phase 4).
After measurement is completed, open valve fully to release any remaining air in the cuff. Remove cuff.
Care and Maintenance
Warning: Before transporting this instrument, mercury must be stored in the tank and the reservoir lock MUST be switched to the off
position to prevent mercury spills.
