METHOD AND SYSTEM TO MEASURE ECG AND RESPIRATION
First Claim
1. A patient monitoring system comprising:
- a plurality of electrocardiogram (ECG) lead channels to communicate with a plurality of ECG electrodes attached to a patient;
an ECG respiration component to produce a first respiration signal based on variations detected in the ECG lead channels;
a pressure measurement channel to communicate with a pressure sensor attached to the patient;
a pressure respiration component to produce a second respiration signal based on pressure variations detected in the pressure measurement channel;
respiration decision logic to produce a respiration rate from at least one of the first respiration signal and the second respiration signal based on respective signal qualities; and
a display device to provide indicia of the respiration rate.

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.
