Respiratory Therapists and Technicians
Respiratory therapists and technicians treat patients with various cardiorespiratory problems. They may provide care that affords temporary relief from chronic illnesses such as asthma or emphysema, or they may administer life-support treatment to victims of heart failure, stroke, drowning, or shock. These specialists often mean the difference between life and death in cases involving acute respiratory conditions, as may result from head injuries or drug poisoning. Adults who stop breathing for longer than three to five minutes rarely survive without serious brain damage, and an absence of respiratory activity for more than nine minutes almost always results in death. Respiratory therapists carry out their duties under a physician's direction and supervision. Technicians typically work under the supervision of a respiratory therapist and physician, following specific instructions. Therapists and technicians set up and operate special devices to treat patients who need temporary or emergency relief from breathing difficulties. The equipment may include respirators, positive-pressure breathing machines, or environmental control systems. Aerosol inhalants are administered to confine medication to the lungs. Respiratory therapists often treat patients who have undergone surgery because anesthesia depresses normal respiration, thus the patients need some support to restore their full breathing capability and to prevent respiratory illnesses.
