The recovery position is a way of placing an unconscious but breathing person on their side so their airway stays clear and any fluid drains from their mouth rather than pooling in their throat. It’s one of the most important first aid techniques to learn because it can prevent someone from choking on vomit or saliva while they’re unresponsive. The position is stable enough that you can leave someone briefly to call for help without worrying they’ll roll face-down.
When to Use the Recovery Position
The recovery position is for someone who is unconscious (or has a significantly reduced level of alertness) but is still breathing normally. That distinction matters. If the person is not breathing or is only gasping irregularly, they need CPR, not the recovery position. So the first thing you always do is check: Are they responsive? Are they breathing? If they’re unresponsive and breathing, the recovery position is the right call.
Common situations where you’d use it include someone who has fainted and hasn’t woken up, a person who’s had a seizure and is now unconscious, someone who’s heavily intoxicated and unresponsive, or a person found unconscious for an unknown reason. International resuscitation guidelines from 2025 recommend the recovery position for anyone with a decreased level of responsiveness who doesn’t need immediate resuscitative interventions like CPR.
Why It Works
When a person loses consciousness, the muscles in their throat relax. If they’re lying flat on their back, the tongue can fall backward and partially block the airway. Rolling them onto their side uses gravity to keep the tongue from obstructing the throat. Just as importantly, if the person vomits, the fluid drains out of their mouth instead of flowing back into their windpipe. This is the same principle behind postural drainage, where gravity helps clear fluids from the airways.
Aspiration, where vomit or saliva enters the lungs, is a serious risk for anyone lying on their back while unconscious. It can cause pneumonia or, in severe cases, suffocation. The recovery position largely eliminates that risk by keeping the head angled downward relative to the throat so fluids flow out naturally.
How to Place an Adult in the Recovery Position
Start with the person lying flat on their back. Kneel beside them and take the arm closest to you and extend it out at a right angle from their body, palm facing up. This arm will act as a brace to prevent them from rolling too far once you turn them.
Next, take their far arm and fold it across their chest so the back of that hand rests against the cheek closest to you. Hold it there. With your other hand, bend the person’s far knee up to a right angle. Now pull that bent knee toward you. The person will roll smoothly onto their side, with their own hand cushioning their head and their extended arm stopping the roll.
Once they’re on their side, adjust the top leg so the knee stays bent at a right angle to keep them stable. Then gently tilt their head back slightly and lift the chin to open the airway. Take a quick look inside the mouth to make sure nothing is blocking the throat. The whole process takes about 15 to 20 seconds once you’ve practiced it.
Monitoring After Placement
Placing someone in the recovery position isn’t a “set and forget” action. International guidelines stress that you should keep checking for signs of airway blockage, abnormal breathing, or further loss of responsiveness. If at any point you can’t tell whether the person is still breathing normally because of their position, roll them onto their back immediately and reassess. If they stop breathing, you’ll need to begin CPR.
If the person needs to stay in the recovery position for more than 30 minutes, consider rolling them onto the opposite side to relieve pressure on the lower arm and reduce the risk of nerve compression or restricted blood flow to that limb.
When Not to Use It
If you suspect a spinal or neck injury, do not move the person unless you absolutely have to. Moving someone with a spinal injury can cause permanent damage. Keep them still and avoid moving their head or neck. If they start vomiting and you must roll them to protect their airway, recruit at least one other person and roll them as a unit, keeping the head, neck, and back perfectly aligned.
Signs of a possible spinal injury include the person having fallen from a height, been in a car accident, or sustained a blow to the head or back. If any of these apply, the safest approach is to keep them on their back, support their head in a neutral position, and wait for emergency services.
Anyone found face-down, in a hunched position, or with their neck bent sharply forward should be carefully repositioned onto their back first and reassessed. These positions are associated with positional asphyxia, where the body’s own posture restricts breathing.
Recovery Position for Pregnant Women
Pregnant women in the third trimester should be placed on their left side specifically. In late pregnancy, the weight of the uterus can compress a major vein called the inferior vena cava when a woman lies flat on her back. This reduces blood flow returning to the heart and can cause a rapid drop in blood pressure, dizziness, nausea, and a fast heart rate. Rolling her onto her left side shifts the uterus off that vein and restores normal circulation. This has been standard medical practice since the 1950s.
Recovery Position for Babies
Infants under one year old are too small for the standard side-lying technique. Instead, cradle the baby in your arms with their head tilted slightly downward. This keeps the airway open and allows any fluid to drain from the mouth rather than back into the throat. Hold them securely, call emergency services, and keep watching their level of responsiveness while you wait for help.
Practicing Before You Need It
The recovery position is simple in concept but unfamiliar in practice. The movements, bending the far knee, folding the hand against the cheek, pulling the knee to roll them, feel awkward the first time. Practice on a willing friend or family member a few times so the steps become automatic. In a real emergency, adrenaline makes fine motor tasks harder, and having muscle memory for the sequence can make the difference between acting quickly and freezing up.
One useful detail people often overlook: the extended arm on the ground isn’t just resting there. It’s the mechanical stop that prevents the person from rolling all the way onto their face. If you skip that step and go straight to rolling, you may overshoot and end up with the person face-down, which is exactly the position you’re trying to avoid.
