Abstract
A method for monitoring the respiration rate of a patient includes attaching a plurality of electrocardiogram (ECG) electrodes and a pressure sensor to a patient, producing a first respiration signal based on variations detected in signals provided by the ECG electrodes attached to the patient, and producing a second respiration signal based on pressure variations detected in the pressure sensor secured to the patient. The method also includes selecting at least one of the first respiration signal and the second respiration signal based on respective signal qualities and producing a respiration rate from the selected signal. The method also includes providing indicia of the respiration rate. The method may also include displaying ECG signals with the indicia of the respiration rate.

26. 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 detect pressure variations in a 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. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A computer readable storage medium having stored thereon executable instructions that, when executed by a processor of an electronic device, cause the electronic device to:
-
communicate with a plurality of ECG lead channels to produce a first respiration signal based on variations detected in the ECG lead channels; detect pressure variations in a pressure measurement channel and produce a second respiration signal based on the pressure variations; and compare respective signal qualities of the first and second respiration signals and select at least one of the first and second respiration signals based on the respective signal qualities to produce a respiration rate; and indicate the respiration rate to a user. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46)
