The recovery position is used to keep an unconscious person’s airway open while they’re breathing on their own. By rolling someone onto their side with their head angled slightly downward, gravity prevents the tongue from falling back into the throat and allows fluids like vomit, blood, or mucus to drain out of the mouth instead of pooling in the airway. It is one of the most important and simplest first aid techniques you can learn.
When to Use the Recovery Position
The recovery position is appropriate when someone is unconscious (or has an altered mental state) but is still breathing normally. This covers a wide range of emergencies: someone who has fainted, a person who is heavily intoxicated, someone recovering from a seizure, or anyone found unresponsive but with signs of life such as breathing, coughing, or movement.
If the person is not breathing or shows no signs of circulation, the recovery position is not enough. That situation calls for CPR. The recovery position is specifically for people whose heart and lungs are still working but who cannot protect their own airway because they’re not conscious enough to cough, swallow, or turn their head.
How It Protects the Airway
When a person lies flat on their back while unconscious, two things can go wrong. First, the tongue relaxes and slides backward, partially or fully blocking the opening to the windpipe. Second, if the person vomits, the fluid has nowhere to go but down into the lungs, which can cause choking or a dangerous lung infection called aspiration pneumonia.
The recovery position solves both problems at once. With the person on their side and their face angled toward the ground, the tongue falls forward rather than backward, keeping the airway clear. The neck is extended slightly, moving the chin away from the chest, which opens the airway further. Any fluid in the mouth drains out by gravity rather than flowing toward the lungs. It’s a simple change in body position that can genuinely save a life in the minutes before emergency help arrives.
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 up. Then take their far hand and press the back of it against the cheek nearest to you, holding it in place. With your other hand, pull up their far knee so the foot is flat on the ground. Use that bent knee as a lever to roll them toward you onto their side.
Once they’re on their side, adjust the top leg so the hip and knee are both bent at right angles, which keeps the body stable and prevents them from rolling onto their face. Tilt their head back gently to keep the airway open, and position their face slightly downward so fluids can drain. Their hand should remain under their cheek to help support the head in this position.
After placing someone in the recovery position, stay with them. Check that they’re still breathing regularly. If you’re waiting more than 30 minutes for help, roll them onto their opposite side to prevent prolonged pressure on one set of limbs and joints. Clinical guidance for patients in side-lying positions generally recommends repositioning every two to four hours to avoid pressure-related injury to the skin and underlying tissue.
When to Modify or Avoid It
If you suspect a spinal injury, such as after a fall, car accident, or any trauma to the head or neck, do not roll the person unless absolutely necessary. Moving someone with a spinal injury can cause permanent paralysis or make existing damage worse. If a person with a suspected spinal injury is vomiting or choking and you must move them, you need at least one other person to help. One person stabilizes the head and neck while the other rolls the body, keeping the head, neck, and back aligned as a single unit throughout the movement.
For pregnant women, the recovery position should be modified so they lie on their left side specifically. When a pregnant person lies on their right side, the weight of the uterus can compress a major vein called the vena cava, which carries blood back to the heart. This compression can trigger a dangerous drop in blood pressure and reduce blood flow to both the mother and the baby. Positioning on the left side avoids this.
Common Situations Where It’s Used
You’re most likely to need the recovery position in everyday scenarios that don’t seem dramatic until they become dangerous. A person who has had too much alcohol and passes out is at serious risk of choking on their own vomit during the night. Placing them in the recovery position before you leave the room could prevent a fatal outcome.
After a seizure, most people enter a period of deep unconsciousness that can last several minutes. During this time, they may drool heavily or vomit. Rolling them onto their side once the seizure movements have stopped is standard first aid. The same applies to someone who faints and doesn’t regain consciousness right away, or a person found unresponsive from a drug overdose or diabetic emergency.
The 2025 American Heart Association guidelines also reference the recovery position for specific clinical situations like gas embolism, recommending it for anyone with altered mental status as consistent with standard first aid principles. The core logic is always the same: if someone is alive but not awake enough to protect their own airway, get them on their side.
What Not to Do
Don’t place someone in the recovery position if they’re not breathing. That person needs CPR, and performing chest compressions requires them to be flat on their back on a firm surface. The recovery position is not a substitute for CPR.
Don’t prop a pillow under an unconscious person’s head thinking it will help. Flexing the neck forward can actually narrow the airway. You want the head tilted slightly back with the chin lifted away from the chest. Don’t leave the person unattended, even if they seem stable. Unconscious people can stop breathing without warning, and you need to be there to notice and respond if that happens.
