You place someone in the recovery position when they are unconscious but still breathing. This is the single most important criterion: the person is unresponsive (won’t wake up when you talk to them or tap their shoulders) yet you can see, hear, or feel normal breaths. If they are not breathing, you skip the recovery position entirely and begin CPR. If they are conscious, they can manage their own airway and don’t need to be repositioned.
Why the Position Matters
When a person is unconscious and lying flat on their back, two things can go wrong quickly. The tongue can fall backward and block the airway, and any fluid in the mouth, whether vomit, blood, or mucus, has nowhere to drain. Both problems can turn a breathing person into a non-breathing person in minutes.
Rolling someone onto their side with their head angled slightly downward solves both issues at once. Gravity pulls the tongue forward and away from the airway, and fluids drain out of the mouth instead of pooling at the back of the throat. Studies confirm that this side-lying position reduces airway obstruction and breathing disturbances compared to lying face-up, in both adults and children.
Common Situations That Call for It
The recovery position applies in a wide range of real-world emergencies, as long as the person is unconscious and breathing:
- Fainting or collapse where the person doesn’t regain consciousness within a minute or two
- Alcohol or drug overdose when the person is unresponsive but still breathing (vomiting is especially likely here, making airway drainage critical)
- Seizures, once the seizure has stopped and the person remains unconscious
- Head injuries that render someone unresponsive
- Diabetic emergencies or severe illness causing loss of consciousness
The underlying cause doesn’t change the decision. If they’re unconscious and breathing, the recovery position is appropriate.
When Not to Use It
There are two clear exceptions. First, if the person is not breathing or you can’t detect normal breaths, they need CPR, not the recovery position. Roll them onto their back on a firm surface and begin chest compressions.
Second, if you suspect a spinal injury, such as after a fall from height, a car crash, or a diving accident, do not move the person. Rolling them can shift damaged vertebrae and cause permanent paralysis. Keep them still and wait for emergency services. The only exception is if they begin vomiting or choking on blood and their airway is in immediate danger. In that case, the Mayo Clinic advises using at least two people to roll the person as a unit, keeping the head, neck, and back aligned the entire time.
How to Place Someone in the Position
Kneel beside the person while they’re lying on their back. Extend the arm closest to you straight out at a right angle from their body, palm facing up. Take their far arm and fold it across their chest so the back of that hand rests against the cheek nearest you. Hold it there.
With your free hand, bend their far knee up so their foot is flat on the ground. Now pull that bent knee toward you, rolling them smoothly onto their side. The hand tucked under their cheek supports the head, and the arm you extended on the ground prevents them from rolling all the way face-down. Adjust their top leg so the knee is at a right angle to stabilize the position.
Finally, gently tilt their head back slightly and lift the chin to keep the airway open. Make sure their face is angled downward toward the ground so fluids can drain freely from the mouth. Check inside the mouth briefly to confirm nothing is visibly blocking the airway.
Modifications for Babies and Pregnant Women
For babies under one year, the standard adult technique doesn’t work. Instead, hold the baby face-down along your forearm, supporting the head with your hand, so gravity keeps the airway clear. Alternatively, lay the infant on their side with their head angled so the mouth faces downward, and use a small rolled blanket behind their back to stop them from rolling over. Children over one year can be placed in the same recovery position as adults.
For pregnant women, always roll them onto their left side. In late pregnancy, the weight of the uterus can compress a major vein that returns blood to the heart when the person lies flat or on their right side. The left-side position keeps blood flowing normally for both the mother and the baby.
What to Do While You Wait
Placing someone in the recovery position is not a one-and-done action. You need to stay with them and monitor their breathing continuously. Check regularly that their chest is still rising and falling, and that you can hear or feel air moving. If they stop breathing at any point, roll them onto their back immediately and start CPR.
If you’re waiting a long time for emergency services, switch the person to their opposite side after about 30 minutes. Staying on one side for too long can restrict blood flow to the lower arm and put sustained pressure on one side of the body. When you switch sides, keep their head supported and their airway open throughout the move.
Call emergency services as soon as you recognize the person is unconscious. If you’re alone, place the person in the recovery position first to protect their airway, then make the call. Having them in a stable side-lying position buys you time to get help without their condition silently worsening.
