Medical Emergencies: CPR, Toxicology, and Wilderness

In this module you will be learning about states of shock and the principles of resuscitation. Unlike our common use of the word shock referring to a mental state of feeling overwhelmed or alarmed, shock is a state of crisis within the body, involving one or more of the organ systems. If left uncorrected, shock can lead to death. The other topic, resuscitation, will cover the principles of treating and reversing shock, and most importantly, the treatment of cardiac arrest. We will discuss the latest scientific research and best practices of cardiac arrest resuscitation.

In this module we are going to learn about poisonings, or toxicologic ingestions. There is a whole field of medicine dedicated to the study of how the thing we ingestion, usually accidentally or in an attempt of self-harm, impact our bodies. This field is called toxicology. A poison is any substance that impairs health or causes death. A toxin is a drug or substance that is poisonous to a human, and will cause an adverse event, maybe even death. An antidote is a substance that will neutralize the effect of the poison or toxin. With an understanding of the basic terminology, we can further explore the most common poisons you will encounter in the field, how they affect the body, and how we treat these patients.

In this module you will learn how environmental emergencies are caused when the body’s physiological functions are disrupted by the patient’s natural surroundings. Many of the body’s functions only function properly at a normal temperature, so a change in the body’s temperature can cause them to fail. Some examples of environmental emergencies include cold or hot temperature changes, illness and injuries caused by other animals, high altitude illnesses and injuries or illness related to water such as drowning.
