Method and system to measure ECG and respiration

摘要

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.

主权项

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.
