Abstract
A method for determining respiration rate in a patient can include various parts. The respiration rate can be determined by measuring the heart's S2 split. The S2 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.
