Infant 0998-00-0003-32
A cuff that is too small for the limb will result in erroneously high readings. The correct
size of the pressure cuff for a given patient has, among other considerations, a direct
bearing on the accuracy of the obtained NIBP measurements. Base your selection of the
cuff size on the limb circumference of the patient. The table above indicates the available
Datascope cuffs for use with the Accutorr Plus. The design dimensions of the cuffs and
their intended uses are based on recommendations of the American Heart Association.
NOTE: The cuffs that are used with the Accutorr Plus use special snap on connectors.
Adapter hoses are available to connect older style cuff connectors. See Optional Accessories,
Section 5.2 in the Operating Instructions for a detailed list of cuffs and adapter hoses.
WARNING: Use only Datascope cuffs. Use of other than Datascope cuffs may result in
erroneous measurements.
The pressure on the limb may not fall to zero between measurements if the cuff is
wrapped too tightly. Therefore, assure that the cuff is properly applied.
The skin is sometimes fragile (i.e., on pediatrics, geriatrics, etc.). In these cases, a longer
timer interval should be considered to decrease the number of cuff inflations over a period
of time. NOTE: In extreme cases, a thin layer of soft roll or webril cotton padding
may be applied to the limb in order to cushion the skin when the cuff is inflated. This
measure may affect NIBP performance and should be used with caution.
* When using the thigh cuff, this product may not comply with product specifications listed in chapter 3.
** The limb circumferences of the color coded cuffs adhere to the AHA guidelines for size. They also incorporate
index and range lines to assist in cuff selection. The cuff bladder and hose contain Natural Latex rubber.
The bladder has a dacron cover.

2. Attach the cuff hose to the NIBP cuff connector (18). To do this, hold the hose behind
the knurled pressure fitting (female). Push onto the male connector until a click is
heard. To remove, hold the knurled female fitting and pull firmly to release.
3. Apply the cuff to the patient. To reduce errors, the cuff should fit snugly, but with
enough room for two fingers to be placed between the cuff and the patient’s arm (on
adults), and with little or no air present within the cuff. Cuff should fit loosely on
neonates. Apply the cuff so that the center of the inflation bag (bladder) is over the
brachial artery. Be sure that the INDEX line on the cuff falls between the two
RANGE lines. If not, a larger or smaller cuff is required. Be sure the cuff lies directly
against the patient’s skin. For best results, the cuff should be placed on the arm at
heart level and no clothing should come between the patient and the cuff. NOTE:
Avoid compression or restriction of the pressure hose.
NOTE: The NIBP cuff should not be placed on a limb that is being utilized for any
other medical procedure. For example, an I.V. catheter.
4. If required, select the patient size with the PATIENT SETUP key (37). On initial power
up, the configurable default setting is used. Otherwise, the last selected patient size is
used. Initial default cuff inflation pressures depend on the Patient Size setting. See
section 1.3.2.2 for details on changing the initial cuff inflation pressure.
5. Press the START NIBP key (38) to begin an NIBP measurement. A beep is sounded
after a completed measurement.
NOTE: Inflate the cuff only after proper application to the patient’s limb. Cuff
damage can result if the cuff is left unwrapped and then inflated.
The cuff begins to inflate to the selected cuff pressure. After reaching the
selected pressure, the cuff begins to slowly deflate and the Accutorr Plus collects
oscillometric pulsations.
If the initial cuff inflation is found to be inadequate, the unit retries with a higher
inflation pressure (+50 mmHg in the adult mode; +50 in the pediatric mode; +40
mmHg in the neonate mode). A triple beep tone is generated. NOTE: Any time there
is an unsuccessful NIBP measurement, a triple beep tone is generated and the Diastolic,
Systolic, NIBP HR, MAP and Timer/Temp LED’s will be replaced with dashes.
Have the patient remain still to avoid unnecessary motion artifact. After the cuff
pressure drops below the diastolic pressure, the results of the measurement are
displayed and the cuff is vented to atmosphere.
If an error code displays in the Systolic Display or a status code in the Room/Bed
Display, refer to Section 1.3.16, Status and Error Codes, for its explanation. A
successful measurement clears a status code. To clear a status code, press the
ROOM/BED NUMBER key (24).
6. When required, press the DEFLATE key (36) to interrupt a measurement. The cuff will
deflate.
NOTE: Once the initial measurement is taken for a room/bed, the Accutorr Plus will
continue to use the selected patient size.
NOTE: Check the patient’s limb for any indications of circulation impairment.
