Hospitals are excellent places to obtain part-time and summer employment. They have a continuing need for helpers in many departments. Even though the work may not be directly related to respiratory therapy, you will gain knowledge of the operation of a hospital and may be in a position to get acquainted with respiratory therapists and observe them as they carry out their duties. If part-time or temporary work is not available, you may wish to volunteer your services.
Ask you career services office or health teacher to help set up interviews with or lectures by respiratory therapy practitioners from a local hospital.
Respiratory therapists 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. Therapists 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.
In evaluating patients, therapists test the capacity of the lungs and analyze the oxygen and carbon dioxide concentration and potential of hydrogen (pH), a measure of the acidity or alkalinity level of the blood. To measure lung capacity, therapists have patients breathe into an instrument that measures the volume and flow of air during inhalation and exhalation. By comparing the reading with the norm for the patient's age, height, weight, and gender, respiratory therapists can determine whether lung deficiencies exist. To analyze oxygen, carbon dioxide, and pH levels, therapists draw an arterial blood sample, place it in a blood gas analyzer, and relay the results to a physician.
Respiratory therapists watch equipment gauges and maintain prescribed volumes of oxygen or other inhalants. Besides monitoring the equipment to be sure it is operating properly, they observe the patient's physiological response to the therapy and consult with physicians in case of any adverse reactions. They also record pertinent identification and therapy information on each patient's chart and keep records of the cost of materials and the charges to the patients.
Therapists instruct patients and their families on how to use respiratory equipment at home, and they may demonstrate respiratory therapy procedures to trainees and other health care personnel. Their responsibilities include inspecting and testing equipment. If it is faulty, they either make minor repairs themselves or order major repairs.
Respiratory therapists work closely with and supervise respiratory technicians, and assistants. They also teach new staff and bear primary responsibility for the care given in their areas. At times the respiratory therapist may need to work independently and make clinical judgments on the type of care to be given to a patient.
