1. A patient monitoring system comprising:

  • an ECG respiration component configured to communicate with a plurality of ECG lead channels to produce a first respiration signal based on variations detected in the ECG lead channels;

    a pressure respiration component configured to be connected to a pressure sensor via a pressure measurement channel, the pressure respiration component configured to detect pressure variations in the pressure measurement channel and to produce a second respiration signal based on the pressure variations;

    respiration decision logic configured to compare respective signal qualities of the first and second respiration signals and to select at least one of the first and second respiration signals based on the respective signal qualities to produce a respiration rate; and

    a display device to provide indicia of the respiration rate.
