Study Notes
Heat Transfer
- Heat is transferred from a warm hand to 70°F (21°C) water via conduction.
Decompression Sickness
- Most prominent symptom: Abdominal or joint pain.
Water-Related Incidents
- Assume possible spinal injury in unwitnessed water-related incidents.
Lyme Disease vs. Rocky Mountain Spotted Fever
- Rocky Mountain spotted fever can cause paralysis and cardiorespiratory collapse, unlike Lyme disease.
Hypothermia
- Occurs when the core body temperature falls below 95°F (35°C).
Frostbite Treatment
- During transport of a frostbitten patient, protect the affected part from further injury.
Drowning Definition
- Accurately defined as death from suffocation after submersion in water.
Scuba Diving Injuries
- Serious injuries from scuba diving are primarily caused by too rapid of an ascent.
Resuscitation in Cold Conditions
- For an unresponsive patient exposed to cold, assess for a carotid pulse for up to 60 seconds.
Lightning Burns
- Burns associated with lightning strikes are typically superficial.
Heat-Related Illness
- In a heat-exposed, confused diabetic patient with weak pulse and low blood pressure, load him into the ambulance and begin rapid cooling interventions.
Pit Viper Envenomation
- An early sign includes local swelling and ecchymosis.
Hyperthermia
- Defined as the body being exposed to more heat than it can lose.
Diving Emergencies
- In a diver with cyanosis and pink froth after rapid ascent, position supine with head elevated, suction, and hyperventilate.
