Pulse oximetry and end tidal carbon dioxide monitoring

摘要

Advanced, noninvasive, patient-side monitors are providing clinicians with more ways to follow physiologic variables when managing complex cases. Pulse oximeters and capnographs provide information on two separate aspects of the respiratory system, gas exchange and ventilation. With newer and less expensive electronics, these monitors are becoming increasingly popular with veterinarians who are eager to provide the best care for their patients and clients. Clinicians preparing to use the machines should have a complete understanding of the mechanics and physiology behind the monitors and a thorough understanding of their limitations.
