ABSTRACT:
A pressure monitoring enteral feeding system and method are disclosed including a housing having a pair of channels for receiving a pump tubing segment which connects an intake line and an output line of a delivery set, and for holding the pump tubing segment adjacent a motor unit. A pair of pressure sensors are disposed along the channels to monitor the pressure in the pump tubing segment so as to warn a user when an undesirable pressure has developed either upstream or downstream from the motor unit, and to adjust rate based on the upstream pressure. The housing may also include a lockable cover to securely hold the pump tubing segment in the channels and in firm contact with the pressure sensors. In accordance with one aspect of the invention, the pressure sensors are used to determine the actual output of the enteral feeding pump by monitoring strain in the delivery set. The pump can then make adjustments to the length of time the rotor turns during each cycle to ensure that partial occlusions, viscosity changes and back pressure do not interfere with proper dosing.
