Provide emergency care, including artificial ventilation, external cardiac massage, and assist staff with cardiopulmonary resuscitation. Collect and analyze arterial blood gases and recognize normal, abnormal and critical values and provide appropriate corrective intervention. Follow physician orders for treatment and evaluate requirements for treatment, such as treatment type, mode and duration of therapy, universal precautions, and medication dosage. Monitor patient’s response to therapy by evaluation of vital signs, arterial blood gases, auscultation of breath sounds, pulse oximetry and end-tidal CO2 measurement. Consult with physicians, nurses and other health care professionals for changes in patient’s status and work as part of the team to manage the patient’s plan of care.
