AVPU Scale and Alert & Oriented x4
A four-step check of level of consciousness, and the four orientation questions you ask once a patient is alert.
Practice testThe scale
Work down the letters and stop at the first one that fits.
Alert
Eyes open, responding to their environment without you having to do anything. Alert is where you stop using AVPU and start asking the orientation questions, because an alert patient can still be completely disoriented.
New ConfusionACVPU
Awake and talking, but newly confused, disoriented or agitated compared with their own baseline. This letter is the addition that makes AVPU into ACVPU.
Voice
No response until you speak to them. Any reply counts: opening their eyes, a groan, moving. They needed a stimulus, so they are not Alert.
Pain
No response to voice, but responds to a central painful stimulus such as a trapezius pinch. Withdrawal, groaning or eye opening all count. Roughly the level where airway protection becomes a live concern.
Unresponsive
No response to voice or pain. Assume no protective airway reflexes and manage the airway first.
The C is the modern update. The National Early Warning Score 2 replaced plain AVPU with ACVPU because new confusion is an early sign of sepsis, metabolic derangement and intracranial pathology, and the old scale filed those patients under Alert and missed them. The word that matters is new: a patient with long-standing dementia sitting at their usual baseline is not scored C, which is why you ask family or staff what normal looks like for this person.
Alert and Oriented x4
Alert means the patient is responding on their own; it does not mean they are oriented. These four questions establish that.
1. Person
“Can you tell me your name?”
2. Place
“Do you know where you are right now?”
3. Time
“Do you know what day it is? The month? The year? The season?”
4. Event
“Do you know what happened? What brought us here today?”
Score it as the number they get right: a patient who knows who and where they are but not the date or what happened is A&Ox2. Name which two, because “x2” on its own does not say which two. Orientation tends to erode in a predictable order, time first and person last, so a patient who does not know their own name is deeply impaired.
How this feeds the Glasgow Coma Scale
AVPU is the screen and the GCS is the score. AVPU fits in the primary survey and tells you in seconds whether you have a problem; the GCS is the reproducible number that gets trended and handed over. As a rough orientation only, an alert patient tends to sit near 15, voice-responsive around 12 or 13, pain-responsive around 8, and unresponsive at 3.
Do not convert one into the other
Those numbers are a feel for severity, not a conversion table. Published agreement between AVPU and GCS is loose, and a converted score in a chart looks like a measured one to whoever reads it next. Document the scale you actually used, and if the GCS is what your service records, take the GCS.
