911 Attempts
The instrument can be unlocked by an authorized operator for a specified number of additional patient
tests after the maximum time between controls has been exceeded. This option is available if the 911
Attempts option is enabled (page 16).
Note: The number of 911 Attempts that can be used to override mandatory QC is specified during
setting of Supervisory Options. A dollar sign ($) will be included on the result printout of any test run
using the 911 Attempts option.
To Use 911 Attempts when QC is Timed Out:
1.
Dispense the sample into the test tube and simultaneously press the START key. A beep signals
the start of the test, and the QC Selections menu is displayed.
Note: If OID or PIN and/or PID options are enabled, other menus will be displayed prior to
the QC Selections menu.
2.
Select a patient test. The QC Overrides that remain are briefly displayed.
Note: The message indicates the number of 911 attempts that will remain for the specified
well once the test is completed. The clotting time is displayed on the screen.
3.
Once all the 911 attempts are used, the instrument disallows patient tests. To allow access to the
instrument, Quality Control must be successfully run or the supervisor must increase the
allowable number of 911 attempts.
OPERATING PRECAUTIONS
The AC/DC Power Module should be plugged into a standard AC outlet to charge the instrument when it is
not in use.
DO NOT remove the AC/DC Power Module from the instrument by pulling on the cord. It is recommended
that the AC/DC Power Module be unplugged from the AC outlet when it is not being used to charge the
instrument.
DO NOT use tubes that are past their marked expiration date or which have been improperly stored.
DO NOT force a tube into the instrument. If resistance to insertion is encountered, gently remove the tube
and examine the test well. Remove any obstruction before attempting further use of the instrument (see
Maintenance on page 38).
DO NOT use excessive force in pressing the instrument keys.
DO NOT expose the instrument to extreme temperatures (above 37 °C).
DO NOT drop the instrument.
DO NOT remove stoppers to deliver a blood sample to the tube.
The HEMOCHRON Response instrument should only be used by healthcare professionals trained and
certified in the use of the system and operated in accordance with facility policies and procedures.
All biohazard safety guidelines pertaining to the handling and disposal of human blood should be strictly
adhered to when collecting and handing blood specimens and when operating the HEMOCHRON Response
Whole Blood Coagulation System.
Used HEMOCHRON test tubes should be considered as potentially infectious. They should be handled
according to individual institutional policies concerning the disposal of potentially infectious materials.
HEMOCHRON Response test results should always be scrutinized in light of a specific patient’s condition or
anticoagulant therapy. Any test results exhibiting inconsistency with the patient’s clinical status should be
repeated or supplemented with additional diagnostic tests.
LIMITATIONS
Test results of the HEMOCHRON Response Whole Blood Coagulation System are affected by poor technique
during blood collection and sample handling. The accuracy of the test is largely dependent upon the quality
of the blood specimen. Refer to the individual assay package insert for specific limitations.
