Methods and systems for monitoring respiration

摘要

A method for determining respiration rate in a patient can include various parts. The respiration rate can be determined by measuring the heart's S 2 split. The S 2 split can be identified by observing the timing of the heart sounds. Other respiration related information, such as respiration phase and the occurrence of apnea, can be identified as well. A respiration monitor of this type may be useful for monitoring sub-acute patients, and outpatients. A sensor for the respiration monitor and an electrode for an ECG monitor may be combined into a single probe.
