Method for determining haemodynamic parameters

Abstract From the Canadian patent

Disclosed herein are methods of determining haemodynamic parameters from patient pressure signals. In selected embodiments the determination is carried out only on the basis of suitable signals so that reliable , recognition of , heartbeats can occur. The methods comprise: receiving patient pressure signals, selecting a patient pressure signal as a reference dividing the , patient , pressure signals and the reference into segments examining the patient , pressure signal segments and the reference segments for artefacts determining a start and end of a heart beat on one patient pressure signal and using non-discarded segments for calculating haemodynamic parameters.
