Breathing apparatus with ventilation strategy tool

Abstract

A system includes a breathing apparatus, a display unit and a processing unit that is operatively connected to the display unit. The processing unit is configured to provide a graphical visualization on the display unit. The graphical visualization in turn includes a combination of a target indication for at least one ventilation related parameter of a ventilation strategy for a patient ventilated by the apparatus, and a reciprocating animation of the at least one ventilation related parameter relative the target indication. The target indication is for instance based on input of a user, such as an operator of the breathing apparatus. Alternatively, or in addition, it may be a default value stored on a memory unit being operatively connected to the processing unit. Alternatively, or in addition, the target indication is based on a measurement value of said patient's physiology or anatomy. In this manner, the system informs clinicians in a clear and easily understandable way how a current patient ventilation is related to a chosen ventilation strategy.
