Optimizing BVS Pump Filling
When the Console is operating in normal (full-flow) mode, flow rate
should be greater than 2 L/min and typically ranges from 3 to
6 L/min.
To optimize blood flow:
1 Be sure that the patient is appropriately hydrated, with filling
pressures within normal ranges. If the patient is hypovolemic,
administer fluids according to hospital protocol.
2 Observe the filling and emptying of the upper bladder. The
bladder should just barely fill the plastic chamber during Pump
systole, and just empty during Pump diastole. If the bladder is too
full, move the Pump higher to reduce inflow pressure. If the
bladder is too empty and the patient is sufficiently hydrated,
lower the Pump to increase inflow pressure.
3 Position the top of the upper bladder 0 to 14 in. (35 cm) below
the patient's atria. Flow rate may decrease if the Pump is
positioned above or below this range.
4 After adjusting Pump height, observe bladder filling for
2 minutes (to allow the system to stabilize) before making
another adjustment.
Mounting the BVS Pump to the Accessory Mounts
Three types of accessory mounts are available to mount the BVS
Pump for transport.
• BVS
®
IV Pole Mount – attaches to a standard IV pole.
• BVS
®
Bed Mount – slips under the patient’s mattress and accepts
a BVS IV Pole Mount.
• BVS
®
Blood Pump Sling – allows the BVS Pump to be mounted
horizontally for transport.
