The recovery position is a way of placing an unconscious, breathing person on their side so their airway stays open and any fluid in their mouth drains out instead of causing choking. It’s one of the most important first aid techniques to know because it can keep someone alive in the minutes before paramedics arrive. The position angles the face and head slightly downward toward the ground, letting vomit, blood, or mucus flow out of the mouth rather than back into the throat.
Why the Position Works
When someone loses consciousness and ends up flat on their back, two things can go wrong. First, the tongue relaxes and falls backward, partially or fully blocking the airway. Second, if the person vomits, which is common during unconsciousness, the fluid has nowhere to go but into the lungs. Inhaling vomit into the lungs (called aspiration) can be fatal even if the person survives whatever caused them to pass out.
Rolling the person onto their side solves both problems at once. Gravity pulls the tongue forward and to the side, away from the airway opening. Any fluid in the mouth flows downward and out. Tilting the neck slightly, moving the chin away from the chest, further opens the airway. It’s a remarkably simple maneuver that addresses the two most immediate threats to an unconscious person who is still breathing on their own.
How to Place Someone in the Recovery Position
Start by kneeling beside the person while they’re lying on their back. Take the arm closest to you and place it at a right angle to their body, with the elbow bent and the palm facing upward. Then take their far hand and press it against the cheek nearest to you, holding it there. With your other hand, pull the far knee up so the foot is flat on the ground.
Now use that bent knee as a lever. Pull it toward you so the person rolls onto their side. Their head should end up resting on the hand you placed against their cheek, which cushions it and keeps the face angled slightly downward. Adjust the top leg so both the hip and knee are bent at right angles, which stops the body from rolling forward onto the stomach. Gently tilt the head back to make sure the airway is open, and check that nothing is visibly blocking the mouth.
If you’re waiting more than 30 minutes for help to arrive, roll the person onto their opposite side to prevent circulation problems in the lower arm. Keep checking that they’re still breathing the entire time. If their breathing stops, roll them onto their back immediately and begin CPR.
When to Use It
The recovery position is for people who are unconscious (or have a significantly reduced level of consciousness) but are still breathing normally. Common situations include fainting, seizures, alcohol or drug overdoses, and diabetic emergencies. The key criteria: the person is unresponsive, they’re breathing, and they don’t need CPR or other resuscitative interventions.
If the person is not breathing or you can’t detect signs of life, do not place them in the recovery position. They need to be flat on their back so you can perform chest compressions and rescue breathing. The International Liaison Committee on Resuscitation specifically notes that if the recovery position makes it harder for you to tell whether someone is breathing, you should immediately roll them onto their back and reassess. Airway assessment always takes priority over positioning.
Special Situations
Pregnancy
For someone who is visibly pregnant, place them on their left side whenever possible. In later pregnancy, the weight of the uterus can compress a major blood vessel that returns blood to the heart when the person is on their back or right side. Rolling them to the left relieves that pressure and improves blood flow. That said, keeping the airway open is still the top priority. If you can only safely position someone on their right side, that’s far better than leaving them on their back.
Suspected Spinal Injury
If you suspect a back, neck, or head injury, moving the person carries risk. A modified technique called the HAINES position (High Arm In Endangered Spine) was developed in 1989 to reduce that risk. Instead of the standard arm placement, you stretch the person’s far arm straight above their head, then roll them onto the same side as that raised arm. This limits the side-to-side motion of the neck and head that could worsen a spinal injury. Your free hand supports the back of their head and neck during the roll.
Some experts have questioned whether the HAINES position offers a meaningful advantage over the standard recovery position, citing limited evidence. In practice, the decision comes down to weighing two risks: the danger of spinal movement versus the danger of an obstructed airway. If the person is vomiting or their breathing sounds obstructed, protecting the airway generally takes precedence.
Infants
For babies, the recovery position follows the same principle (side-lying, head angled slightly down) but the technique is simpler. Because an infant is small enough to hold, you can cradle them in your arms with their head tilted slightly downward, supporting the head and neck while keeping the airway clear. Avoid overextending an infant’s neck, as their airways are much smaller and more flexible than an adult’s.
What to Monitor While Waiting
Once someone is in the recovery position, your job isn’t finished. Stay with them and watch their breathing closely. Look for the rise and fall of the chest, listen for breath sounds, and feel for air coming from the nose or mouth. If breathing becomes irregular, very shallow, or stops entirely, roll the person onto their back and start CPR right away.
Keep the airway clear by checking the mouth periodically for fluid buildup. Note any changes in skin color, particularly bluish tinting around the lips or fingertips, which signals the person isn’t getting enough oxygen. If the person begins to regain consciousness, reassure them calmly and keep them still until help arrives.
