Smart InvBP and flushing
Flushing is performed to keep the lines open. It prevents blood from clotting and occluding the
lines and measurements. Infusion that is used for flushing goes through the dome into the
patient’s artery.
Two types of flushing are used simultaneously: flushing with continuous infusion and manual
flushing. Flushing with continuous infusion uses a higher pressure than the patient’s blood
pressure and contains Heparin to prevent blood from clotting. Manual flushing is always used
after having taken a blood sample, and every now and then to ensure that the lines remain
open.
The monitor detects the pressure used for infusion to flush the invasive blood pressure line.
There is a 40 second time-out for performing the flushing. The digits change to dashes, ---/--- ,
and there are no alarms. After 40 seconds, or when flushing is completed and patient’s pulse
detected, the pressure digits are displayed and alarms become active. If pressure values are
outside the alarm limits, an alarm is given.
The monitor functions the same way when blood samples are taken.
