If you’ve been following along with our MARCH series, you know we’ve already covered the "M" (Massive Hemorrhage) and the "A" (Airway). By this point in a trauma scenario, you’ve stopped the bright red, spurting blood with a tourniquet or wound packing, and you’ve made sure the patient has a clear path for air to travel from their mouth to their lungs.

But here is the reality: a clear airway doesn’t matter if the "bellows" (the lungs) aren’t working.

You’re walking through a crowded parking lot in Nassau County or navigating the hustle of a subway platform in the city. Your phone vibrates in your pocket. Do you look down? Most people do. They dive into the digital screen, effectively putting on a pair of blinders while the world moves around them.

For the "Concerned Citizen," this isn't just a bad habit, it’s a tactical error.

Let’s be real for a second: a gunfight is just a medical emergency with a loud noise at the beginning.

Most people spend thousands of dollars on the latest sub-compact pistol, red dot sights, and custom holsters, but they carry exactly zero medical gear. Or worse, they carry a kit filled with "stuff" they saw in a YouTube video that has no business being used in a life-or-death situation.

In our last post, we kicked off the MARCH series by tackling the "M", Massive Hemorrhage. We talked about how uncontrolled bleeding is the leading cause of preventable death on the battlefield and in the civilian world alike. You’ve learned how to high-and-tight that tourniquet and pack a wound like a pro. But once the bleeding is under control, your job isn't done.
