The purpose of this study is to compare thermographic estimates of respiratory rate to manual counting (visual inspection) and thoracic impedance-based methods. Thermographic methods rely on detection of temperature changes in the nose and mouth that occur as room temperature air passes through the nose and mouth during ventilation, and may offer a non-invasive means of measuring respiratory rate without requiring any patient contact.

Using a FLIR camera, a thermographic recording will be taken of the patient while breathing. Simultaneously, the research investigator will record the thoracic impedance-based respiratory rate as well as manually count respirations in one minute.
