So, let’s make it simple and go back to our DRScABCDE.
The first consideration is whether it’s safe for you to approach. Always remember how important it is to keep yourself safe. You’re no use to anyone if you’re injured or worse.
If it is safe, check for response using AVPU. Are they alert, responding to voice or physical stimulus? In this case, the casualty is unresponsive - so we need some help. If you haven’t done so already, It’s also time to let the bridge know that there is an incident taking place.
In this case there is no catastrophic haemorrhage, and it doesn’t appear that our casualty has fallen from a height. They are lying on their side and position wise, they look a bit like they lay down for a snooze! They’re pretty much in the recovery position already. But how do we know whether the unconsciousness is due to a medical issue or trauma? We don’t.
Lucky for us, and the casualty, it doesn’t matter because what we do next is exactly the same. We open the airway and check for breathing (for up to 10 seconds). Our casualty is breathing quite quickly at 24 respirations per minute but they’re maintaining their own airway.
