Emergency Medical Response
You Are the Emergency Medical Responder
You arrive at the scene of a motor-vehicle collision, a fender bender, in which a woman who was driving her husband to the hospital because he was complaining of chest pain, rammed into the car in front of her. A police unit is on the scene assisting the husband, who collapsed and apparently is unconscious. Your partner proceeds to help the police officer with the unconscious patient. You notice that the woman is clutching one of her arms.

Emergency Medical Response
Activity
You arrive at the home of a patient who is lying on the ground. A 6-foot ladder is nearby and hedge trimmers are on the ground next to the patient. The patient’s leg is twisted and he is moaning in pain. The patient is alert and responsive. He tells you that he was on the ladder trimming the hedges and his foot slipped. “I fell to the ground and I think I may have broken my leg. It hurts really badly and I can’t move it.” His wife confirms the events.

Emergency Medical Response
Blood Pressure Measurement
Equipment• Sphygmomanometer• Stethoscope
Measured in millimeters of mercury• Systolic: force exerted against arteries when
heart is contracting• Diastolic: force exerted against arteries when
heart is between contractions

Emergency Medical Response
Ongoing Assessment
Every 5 minutes if patient unstable; every 15 minutes if patient is stable
Reassessment of―• Primary assessment• Vital signs• Chief complaint• Interventions or care provided

Emergency Medical Response
Pulse Oximetry
Measurement of oxygen saturation percentage; usually obtained with vital signs
Normally 96 to 100 percent SpO2
Reading below 94 possibly indicates hypoxia
![Page 18: Emergency Medical Response You Are the Emergency Medical Responder You arrive at the scene of a motor-vehicle collision, a fender bender, in which a woman.](https://reader036.fdocuments.in/reader036/viewer/2022062804/5697bf7d1a28abf838c849ad/html5/thumbnails/18.jpg)
Emergency Medical Response
Indications for Pulse Oximetry
Situations where patient’s oxygenation is a concern All patients with neurologic, respiratory or
cardiovascular complaints All patients with abnormal vital signs All patients receiving respiratory depressants Critical trauma patients

Emergency Medical Response
Factors Reducing Pulse Oximetry Reliability
Hypoperfusion, poor perfusion Cardiac arrest Excessive motion of the patient during a reading Fingernail polish Carbon monoxide poisoning Hypothermia or other cold-related illness Cigarette smoking Edema Time lag in detection of respiratory insufficiency
