Evaluating Neurovascular Function in the Backcountry

By Todd Mullenix February 6, 2024

Wilderness Medicine

When it comes to emergency medicine — whether in an urban setting or the backcountry — swift and accurate assessments play a pivotal role in determining the severity and progression of an injury and deciding the best course of action. 

The decisions you make regarding treatment, evacuation, and transportation in cases of non-obvious threats to life and limb can determine not only whether someone lives or dies, but also their quality of life should they survive the emergency. After all, quality of life is a huge part of being alive. And a beating heart with minimal brain activity doesn’t always meet a person’s definition of “living.”

The National Center for Outdoor and Adventure Education (NCOAE) is a leading provider of wilderness medicine education and certification, and in this post, we’re taking the time to introduce you to the process of evaluating neurovascular function to determine the extent and progression of an injury. By doing so, you can make well-informed treatment, evacuation, and transportation decisions when responding to a medical emergency, no matter the origins of the incident.

Understanding What a Neurovascular Assessment Entails

A neurovascular assessment is a collection of tests used by medical clinicians, including emergency medical personnel such as Wilderness First Responders and Wilderness EMTs, to determine whether someone is suffering nerve damage or impaired blood flow. Neuro refers to anything related to the body’s nervous system, and vascular refers to anything related to the body’s blood vessels. Neurovascular function encompasses the interplay between the brain, spinal cord, peripheral nerves, and blood vessels that supply oxygen and other vital nutrients to organs, limbs, and tissues. Any disruption of this intricate balance can lead to severe consequences ranging from impaired cognition to more severe conditions such as stroke or the loss of a limb.

Neurovascular status can be determined by simple tests of the following three functions: (more…)

What Is Wilderness Medicine?

By Todd Mullenix January 15, 2024

Wilderness Medicine

When the average person encounters the term “wilderness medicine,” they typically assume it is referring to the practice of medicine in a remote or harsh environment with little to no access to medical equipment or supplies. 

They may imagine a scenario of providing CPR to someone who suffered cardiac arrest during a whitewater rafting adventure or creating a splint out of a branch and a few strands of twine to help a hiker with a sprained ankle become ambulatory. 

While these notions of wilderness medicine aren’t far off the mark, they are limited. In other words, close but no cigar. It’s all the above and more, which makes it a challenge to come up with a clear and comprehensive definition. 

Teaching Wilderness Medicine at NCOAE

Here at The National Center for Outdoor Adventure and Education (NCOAE), our wilderness medicine courses begin with a discussion of what wilderness medicine is, as well as what each student hopes to learn from the course. Often, these discussions elicit points of discussion that require an even broader definition of the term.

While there’s no universally agreed upon definition of wilderness medicine, certain components set it apart from non-wilderness medicine. For the purpose of this blog post, let’s begin with the following definition:

Wilderness Medicine is provision of medical care when environmental conditions play a stronger role in decision making and interventions than the established systems of care

Wilderness Medicine encompasses not only the treatment of injuries and illnesses in these settings but also includes preventive measures, survival skills, and the management of environmental hazards such as extreme weather, hazardous terrain, and wildlife encounters.

Wilderness medicine skills and techniques can be applied in a variety of setting, including but not limited to: (more…)

SOAP Notes Keep Wilderness Medicine Clean

By Todd Mullenix October 19, 2023

Wilderness Medicine

In the context of wilderness medicine, soap and SOAP are both indispensable. An explanation is in order. We’re all familiar with lower-case soap. This noun refers to a substance that’s added to water to remove dirt, grease, grime, and germs from various surfaces, including skin, hair, clothing, pots and pans, and so on.

Soap In The Wilderness

Traditional soap works in two ways — as a surfactant to break water tension, improving water’s ability to penetrate surfaces, and as a molecule that has a love-hate relationship with water. Soap molecules have two ends, one that’s hydrophilic (loves water) and the other that’s hydrophobic (hates water). The hydrophilic end binds to water, while the hydrophobic end binds to anything other than water — dirt, grease, grime, germs. Imagine soap molecules as tiny carabiners that shackle dirt molecules to water molecules to enable the water molecules to usher them away.

In backcountry and wilderness settings, soap plays a vital role in preventing infection and transmission of disease. In fact, scrubbing vigorously with soap and water may be among the most important risk-management technique you practice during your time in the wilderness.

SOAP (Subjective, Objective, Assessment, Plan)

Now let’s move on to the other SOAP — all uppercase — which is an acronym for Subjective, Objective, Assessment, and Plan. As an outdoor educator, field instructor, or wilderness guide, this note-taking procedure is nearly as important as scrubbing your hands regularly with soap and water. This is especially true when you’re dealing with a client injury or illness in a remote setting

SOAP Notes, which I’ll be covering in this post, separate important information from the chaos and fog of emotion in order to provide clean, uncluttered details for making informed medical decisions and emergency response plans. 

With SOAP Notes in hand, field instructors and outdoor educators trained in wilderness medicine, as well as backcountry guides, are better prepared to respond to a medical emergency. They do this by:

  • Following an organized, methodical process
  • Tracking changes in a patient’s health status
  • Keeping a record of assessments, anticipated problems, and any interventions already provided
  • Communicating with emergency responders
  • Ensuring a seamless transfer of patient care to next-level healthcare providers
  • Documenting cases and care for improving organizational outcomes

Here at The National Center of Outdoor Adventure and Education (NCOAE), we developed the SOAP Note form shown below.

What Outdoor Industry Pros Recommend You Keep in Your First-Aid Kit

By Kate Javes February 6, 2023

Wilderness Medicine

Having a first aid kit handy is always a good idea, but what should it contain? The answer to this question really depends on what you plan to be doing. There are different considerations for a kit that you carry in your car versus one that you grab up for a mountain bike ride or take with you on an overnight or multi-day backcountry expedition. 

Of course, you could purchase pre-stocked first-aid kits for a variety of purposes. Retailers and companies like REI, Adventure Medical Kits, and even Amazon and Target all sell first aid kits that may be right for your purposes. These can be convenient, and many are vacuum sealed to save space. However, they can be expensive and may contain less useful items for your purposes.

Putting together your own first aid kit lets you decide how many and what kinds of things you want. It also gets you thinking about what you’ll have on hand should a backcountry emergency occur. 

Pro Tip: Make sure your backcountry first aid kit is waterproofed and check it regularly to make sure things haven’t been damaged or have expired. 

Here are some things to consider when creating your own backcountry first aid kit:
