HEART RATE AND RESPIRATORY MONITOR

摘要

Apparatus for detection of pulse repetition rate and oxygenation of blood flow, comprising a solid state probe having a narrow bandwidth light source housed to direct light upon a patient's finger and a photodetector housed for receiving reflected light from such finger, the output of the detector being connected to electronic circuitry for detecting pulse repetition rate of blood flow and for detecting signal level representative of the degree of oxygenation of the patient's blood. The use of a low power narrow bandwidth light source with a red emission characteristic permits precise detection of the degree of oxygenation of the blood.
