To the untrained eye, AVPU might look like just another jumble of letters that medics throw around, but for the initiated, it's the “101” of quickly assessing someone's responsiveness. If you've ever watched an episode of ER (the TV show, not the actual emergency room), you might've seen doctors and nurses shouting "AVPU! Initiate level 3 trauma protocol!" across crowded rooms.
Okay, I may have added the dramatic shout, but you get the gist.
Why should EMT students pay special attention to these four letters and what life-saving knowledge do they hold? Let's break it down, shall we?
A - Alert
When we ask if someone is “A” in the AVPU scale, we're not inquiring if they're wide awake and greeting the day with open arms. We're typically checking if the person is alert and oriented to person, place, time, and events.
What it looks like: A person who is alert will respond coherently when spoken to, knows where they are, the current time, and what happened.
How to check: Basically, ask some casual questions: “Can you tell me your name? Where are we right now? What's the date?” Not exactly a pop quiz, but we're not asking for a thesis either.
V - Verbal
Things start to get a bit hairy when we move down the scale to “V.” This is when a person might be groggy, disoriented, or just isn’t making a whole lot of sense when spoken to.
What it looks like: You may need to repeat your questions, and the answers might not be very relevant or coherent. It's like conversing with your uncle after Thanksgiving dinner, but make it a little less about alien conspiracies.
How to check: Don’t get too creative here; just ask some direct, but simple, questions.
P - Painful
Reaching the "P" stage is when things get real. If someone is only responding to painful stimuli, that's a significant red flag.
What it looks like: Responding only to pain means the individual is unresponsive to vocal or verbal stimuli but will react to pain – or even the mention of a high school P.E. class. (not really)
How to check: A sternal rub (yes, it's still a thing) but you only need to do it once, or a light pinch on the shoulder should yield some type of response.
U - Unresponsive
Finally, we come to “U,” a place where we fear to tread, but find ourselves all too often in the profession. If a person is unresponsive, especially after applying painful stimuli, it's a serious situation.
What it looks like: Unresponsive individuals are, as the name suggests, not responding to pain or any other form of stimulus. Bilateral pupils not responding to light would be of particular concern.
How to check: The good old tap-and-shout, followed by a sharp “Hey! Are you okay?” If there's no response, following it up with one sternal rub may stir a sleeping response.
Summing Up
In the realm of first response, delving into the world of AVPU can be a little bit like navigating your way around a minefield; it’s tense, and you don’t want to make any missteps. Yet, understanding these four letters gives us essential insight into a patient's condition and a quick tool to communicate how we’re being “responded” to.
So, EMT students, first responders, and every healthcare professional in between, remember to check for A, V, P, and U in quick succession during any patient encounter. It might just save a life, or at the very least, earn you some points in the dramatic storytelling department.
Diving into the world of emergency response can be exhilarating, daunting, and everything in between. But remember, you're never alone in this journey.
