Respiratory Care is an allied health specialty concerned with the performance of diagnostic cardiopulmonary evaluation and respiratory therapy treatment applied to patients with deficiency and abnormalities of the cardiopulmonary system. It includes related education of the patient, family, and public. Cardiopulmonary evaluation includes the acquisition, analysis and interpretation of data obtained from physiologic specimens, performance of diagnostic tests, studies and research of the cardiopulmonary system, as well as neurophysiologic studies related to respiratory care. Specific testing techniques are employed in respiratory care to assist in diagnosis, monitoring treatment and research. This is understood to include measurement of ventilatory volumes, pressures, flows, blood gas analysis and other related physiologic monitoring. Respiratory therapy techniques include the application and monitoring of medical gases and related administration apparatus, environmental control systems, humidification systems, aerosols, inhaled medications, ventilatory support, bronchopulmonary drainage, pulmonary rehabilitation, cardiopulmonary resuscitation and airway management.
