pump monitor.

2) Check the needle position and access patency.
3) Ensure that the transducer protector is dry and the monitor line is
open. Replace transducer protector, if necessary.
4) Check to see if blood flow rate is too high, especially with a pre-
pump monitor.
Note: Pre-pump arterial monitoring is very sensitive to
access problems (e.g., access spasms, needle tip
occlusions from patient movement). A slower blood pump
rate will bring the pre-pump arterial pressure up. Assess
whether the patient's access is capable of delivering the
prescribed blood flow.
5) Press the RESET key to reset the alarm. If applicable, press the
RESET key again and hold for two seconds to select new alarm
limits. It may be necessary to start the blood pump at a slower
speed and gradually work up to the prescribed rate. If unable to
reset alarm, return blood to the patient if possible. Do not return
clotted blood to the patient.
