Warnin s and Precautions
Warnin - A warning statement in this manual identifies a condition or practice which, if
not corrected or discontinued immediately could lead to patient injury, illness, or death.
Caution - Do not allow a blood pressure cuff to remain on patient for more than 10 minutes
when inflated above 10 mmHg. This may cause patient distress, disturb blood circulation,
and contribute to the injury of peripheral nerves.
Warnin - If luer lock connectors are used in the construction of tubing, there is a possi-
bility that they might be inadvertently connected to intravascular fluid systems, allowing
air to be pumped into a blood vessel.
Warnin - Safety and effectiveness with neonate cuff sizes 1 through 5 is not established.
Warnin - Do not twist connectors when joining the blood pressure cuff to the tubing -
this may cause the connector to stick and make changing BP cuffs difficult.
Warnin - When using with an infant or child cuff, extra care must be taken to prevent
over-inflation. With smaller cuffs (infant or child) the cuff can inflate to over 300mmHg
with just two full compressions of the bulb. To prevent discomfort or injury to the patient
and damage to the instrument, bulb should only be partially squeezed, so that each
“stroke” inflates the cuff in 40mmHg to 60mmHg increments until inflated to the desired
level.
Warnin - This product may contain a chemical known to the state of California to cause
cancer, birth defects, or other reproductive harm.
Caution - Federal law restricts this device to sale by or on the order of a physician or li-
censed healthcare practitioner.

Your DIAGNOSTIX™ 972 consists of main unit with 5mm calibrated unbreakable
plastic cartridge tube, inflation system (which includes the ADCUFF™nylon cuff
with Size Guide™marking system, latex-free inflation bladder, bulb, and the AD-
F OW™ valve), 8 ft. length of coiled tubing, luer connectors, assembly tools, and
operating instructions.
To assemble inflation system to main unit, connect free end of coiled tubing to
air inlet nipple at rear of mercury column above integral cuff storage compart-
ment. Insert male luer adaptor on opposite end of coiled tubing into female luer
connector on bladder. Store folded inflation system in cuff storage compartment
behind mercury column of main unit.
For assembly of the mobile stand, consult booklet entitled “DiagnostixTM 972 As-
sembly Instructions.”
Operatin Instructions
Your DIAGNOSTIX™972 Mobile Mercury Sphygmomanometer incorporates a
special safety feature that locks the mercury within the reservoir during mainte-
nance.
To Operate the DIAGNOSTIX™972: To release the mercury from the reservoir,
move the locking lever (located in front of unit below mercury column), left to
the position marked “ON.” 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 top
of the unit towards you. If the mercury fails to rise, or doesn’t reach the “0” level
have the unit serviced.
To Lock Mercury within the Reservoir: Tilt the top of the unit away from you to
permit mercury to flow out of cartridge tube and into reservoir. When cartridge
tube is completely emptied of A mercury (and while it is still tilted), move lock-
ing lever right to the “OFF” position.
P EASE NOTE: MERCURY SHOU D BE SECURED WITHIN THE RESERVOIR
DURING TRANSPORT, OR WHEN SERVICING THE CARTRIDGE TUBE, DI-
APHRAGMS, OR FI TERS. NEVER DISASSEMB E UNIT UN ESS MERCURY IS
FIRST OCKED WITHIN RESERVOIR. CONSU T SEPARATE INSTRUCTIONS FOR
ASSEMB Y OF MAIN UNIT (ENC OSED).

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 spe-
cially designed to promote the precise,
accurate determination of blood pres-
sure. 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 blad-
der, 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 ADF OW™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 dis-
appearance of these sounds (Phase 5) diastolic pressure. (Some healthcare profes-
sionals prefer recording diastolic 1 and diastolic 2. Diastolic one occurs at phase 4).
After measurement is completed, open valve fully to release any remaining air in the
cuff. Remove cuff.
Care and Maintenance
Stora e - After measurement, wrap cuff around bulb and store behind main unit in
the integral cuff basket.
Manometer - Periodically replace the filter plug and diaphragm, and clean the inside
of the plastic cartridge tube using alcohol and a lint free pipe brush. Units should be
cleaned and serviced periodically depending on frequency of use, or whenever inside
of cartridge tube appears dirty. Proper servicing of your mercury unit according to a
strict maintenance schedule will assure maximum measurement accuracy and extend
the life of your instrument.
For directions on disassembling the unit refer to the enclosed schematic diagram and
accompanying instructions.
PLEASE NOTE: Mercury is toxic. Secure mercury within the reservoir before servicing
unit. Always wear protective clothing (gloves and goggles) when cleaning the unit.
Clean any spilled mercury promptly using approved mercury containment kits. Con-
sult the enclosed manual entitled “
Just in Case ” for procedures on dealing with a
mercury spill.
