First Aid · Water Emergencies
Drowning recognition, the rescuer's first rule, CPR after submersion, secondary drowning awareness in the hours that follow — and the recovery position for an unconscious person who is breathing.
Drowning recognition
The popular image of a drowning person — arms waving, shouting for help, making a dramatic scene — is almost entirely a fiction created by television and film. Real drowning is the opposite. An actively drowning person is typically vertical in the water, arms pressing down on the surface, head barely above the waterline, mouth alternating between air and water, completely unable to wave, shout, or signal in any way.
Their entire body is focused instinctively on one thing: keeping the airway at the water surface for one more breath. There is nothing left over for calling out, waving at shore, or splashing. They may look, to a casual observer, like someone just floating quietly — or simply watching the action at a distance. This is why drowning happens in plain sight, in populated areas, with observers nearby.
Knowing what to actually look for is one of the most specific and actionable pieces of information in this entire guide.
What an actively drowning person looks like
Head low in the water
Mouth at or below the waterline, tilted back trying to breathe
Body vertical, no forward movement
Not swimming — legs not kicking, not moving toward shore or toward anything
Arms pressing down on the water
An instinctive attempt to stay at the surface — not waving, but pushing down
Glassy, unfocused eyes
Or eyes closed, or a blank stare at the shore or sky without movement toward it
Hair over the face
Not pushed back — no available movement for grooming reflexes
Not responding to calls
If you shout to someone and they don't respond or react — treat it as drowning until confirmed otherwise
The simple test: If a person in the water is in the position described above and doesn't respond to a shout, they need help. Act before you're certain.
High-risk factors
Cold water shock
When the body is suddenly immersed in cold water (below 60°F / 15°C), the shock response triggers an involuntary gasp that can inhale water, followed by hyperventilation, rapid heart rate, and within minutes, cold incapacitation — the muscles lose coordinated function.
A strong swimmer who unexpectedly falls into cold water can be incapacitated within 3–5 minutes and lose the ability to swim or tread water regardless of fitness level. This is why capsizing accidents in cold water kill people who could have easily swum to shore in warm water.
If you fall into cold water: don't fight the gasp reflex. Float on your back. If near a boat, don't attempt to swim to shore — concentrate on staying at the surface and getting out of the water first.
Children and drowning
Drowning is a leading cause of accidental death in children under 5. Most child drownings happen in home swimming pools — not lakes or beaches — and most happen during non-swim times when the child is not expected to be near the water.
Physical barriers (pool fencing with self-latching gates), constant adult supervision within arm's reach, and swim lessons beginning around age 1 are the most effective preventions. A child can drown silently in the time it takes to answer a phone call.
Rescue priorities
The universal order of rescue prioritizes keeping the rescuer out of the water. A drowning person in active panic will push down on anything within reach — including a rescuer — in an attempt to stay at the surface. Multiple drowning deaths involve a well-meaning bystander who jumped in and was pulled under by the person they were trying to save.
This is not a failure of courage. It is physics. An untrained rescuer who enters the water near an actively drowning person becomes a drowning victim.
First
From solid ground, extend anything the person can grab — your hand, a towel, a belt, a rope, a fishing pole, a paddle, a tree branch, a piece of clothing. Brace yourself firmly before extending. Be ready for their weight.
Second
Throw anything that floats — a life ring, a pool noodle, a cooler, a sealed water bottle, a bag, a life jacket. Throw it beyond the person and drag it toward them, or throw it near them so they can reach it. Shout instructions: "Grab it — I'll pull you in."
Third
If shallow enough to wade safely, enter the water while holding onto a fixed object — a rope, a ladder, a post, another person onshore bracing you — and extend something to the victim. Or use a boat, kayak, paddleboard, or any floating craft to approach without direct body contact.
Last
If all other options have been exhausted and immediate entry is the only option: keep something between you and the victim — a flotation device, a paddle, a rope — so they cannot grab onto you directly. Approach from behind when possible. Trained lifesavers learn specific holds to prevent being pushed under. Without training, minimizing direct contact is the priority.
Call 911 in every case
Call 911 the moment you recognize a drowning situation — or shout to a bystander to call while you begin rescue. Do not delay calling to attempt rescue, and do not skip calling because the person appears to be recovering after rescue. Every submersion event warrants emergency services evaluation.
Dispatchers can guide you through post-rescue care, including CPR, while help is on the way.
If no flotation is available
Improvise. A sealed cooler, a ball, a rolled-up jacket in a waterproof stuff sack, an empty plastic container, an inflated air mattress — anything buoyant can be a throw rescue device. The goal is giving the victim something to hold onto that doesn't require you to be in arm's reach.
If at a pool or near water regularly, know where the life ring or reaching pole is before you ever need it. The three seconds you save locating it matter.
After submersion
Once the person is safely out of the water, the priority sequence is the same as any emergency: call for help, check responsiveness and breathing, and begin CPR if needed. Rescue from the water is the extraction phase — the first aid begins on land.
Do not assume a person who was submerged is "fine" because they are conscious. Even a brief submersion can cause significant respiratory compromise that develops over the following hours. Every person pulled from the water warrants medical evaluation.
Call 911 if you haven't already
Call immediately. Every submersion event is a 911 situation regardless of initial apparent condition.
Check for responsiveness and breathing
Tap the shoulders and shout. Look, listen, and feel for normal breathing. This takes 5–10 seconds.
If not breathing: begin CPR
Drowning is a respiratory emergency before it is a cardiac one. Full CPR — including rescue breaths if you are trained and willing — is appropriate for drowning victims. Begin immediately and continue until help arrives or the person begins breathing. Rescue breaths provide the most value in drowning CPR; if you cannot or will not give rescue breaths, compression-only CPR is still far better than nothing.
If breathing: recovery position and monitoring
Place the person in the recovery position (see below) to keep the airway clear and allow any water to drain. Cover them to prevent hypothermia — a significant risk after cold-water submersion. Monitor breathing continuously until help arrives.
Treat for hypothermia
Remove wet clothing if possible. Wrap in dry blankets, sleeping bags, or dry clothing. Warm the core first. Keep the person still and horizontal. Full hypothermia guidance is on the Head, Dental & Environmental page.
Cold water drowning
Cold water provides some neuroprotective effect by slowing metabolic processes. There are documented cases of full recovery after cold-water submersions lasting 20–40 minutes — especially in children, whose bodies cool faster and whose brains tolerate cold better. Do not assume a cold-water drowning victim is beyond help based on submersion time.
Begin CPR and continue. Let emergency medical personnel make the determination. "Not dead until warm and dead" is a well-established principle in emergency medicine for hypothermic cardiac arrest.
Don't delay CPR to drain water
Older guidance sometimes recommended tilting or compressing the chest to drain water from the lungs before beginning CPR. Current guidance from the American Red Cross, American Heart Association, and Wilderness Medical Society is clear: do not delay CPR to attempt to drain water. The water in the lungs does not prevent CPR from being effective, and the delay costs critical time.
If the person vomits during CPR — which is common — turn them briefly to clear the mouth, then continue compressions.
Spinal injury concern
Spinal injury should be suspected in diving accidents, surfing impacts, and any high-energy submersion event. For recreational swimming drowning not involving a dive or impact, spinal injury is less likely — and delaying CPR to manage a possible spinal injury in a person who isn't breathing is not appropriate.
If spinal injury is suspected and the person is breathing: minimize neck movement during extraction and positioning. If the person is not breathing and needs CPR: begin CPR, minimizing but not prioritizing spinal precautions over airway and circulation.
Secondary drowning
Secondary drowning — more accurately called submersion injury or delayed drowning — occurs when water that entered the lungs during a submersion event causes respiratory complications hours after the person appears to have recovered. The person is pulled from the water, coughs a bit, says they're okay, and seems to be fine. Then, 1 to 24 hours later, they develop symptoms that indicate the lungs are in distress.
This is not common in every swimming incident — it follows significant submersion events where the person genuinely took in water. But because the initial presentation is deceptively normal, families and caregivers often miss the warning window. This is particularly important for children, whose smaller lung volume means the same amount of water creates proportionally greater compromise.
Symptoms to watch for — 1 to 24 hours after a significant submersion
Persistent or worsening cough
Chest pain or chest tightness
Shortness of breath or labored breathing
Unusual tiredness or lethargy beyond what exertion would explain
Behavior changes — irritability, confusion, unusual drowsiness
Vomiting after the event
If any of these symptoms develop: Go to an emergency room the same day — not urgent care, not a "wait and see." Submersion injury can progress to pulmonary edema and respiratory failure. It is treatable when caught early and dangerous when missed.
The guideline: Anyone who had a significant submersion event — not a brief head dip, but actual water inhalation, coughing on the way out of the water, or loss of consciousness in the water — should be monitored closely for 24 hours and evaluated at an emergency department the same day if any respiratory symptoms appear.
What causes it
When water enters the lungs, it disrupts the surfactant — the coating that keeps the tiny air sacs (alveoli) open. Without surfactant functioning properly, those sacs begin to collapse, fluid accumulates, and the lungs become progressively less able to transfer oxygen to the blood. This process can take hours to manifest.
Saltwater submersion carries a higher risk of secondary drowning than freshwater — saltwater draws additional fluid into the lung tissue from the bloodstream. But both warrant monitoring after significant inhalation.
How common is it?
Secondary drowning is uncommon — it represents a small percentage of submersion events. But its relative rarity is exactly why it gets missed: parents and caregivers see a child who seems fine and assume the danger has passed.
The conservative approach — monitoring for 24 hours and seeking care if any respiratory symptoms develop — costs very little and prevents the handful of cases that become serious.
The recovery position
The recovery position is used for a person who is unconscious but breathing normally. It places them on their side in a stable position that keeps the airway open, prevents the tongue from falling back and blocking the throat, and allows any fluid — vomit, water, blood — to drain from the mouth rather than be aspirated into the lungs.
It is a bridge position: used while waiting for emergency help, maintaining the person safely in an unconscious state they can do nothing about themselves. The person cannot protect their own airway. You are providing that protection by positioning them correctly.
The recovery position should not be used if CPR is needed — an unconscious person who is not breathing needs CPR, not positioning. It should not be used if spinal injury is suspected unless the airway cannot be managed in any other way. Life comes first, then spinal alignment.
Position yourself on the side you intend to roll them toward. Make sure the person is on their back on a flat surface if possible.
Place the arm nearest to you at a right angle to the body, elbow bent, palm facing upward. This arm acts as a stabilizer and prevents the person from rolling onto their face.
Take their far arm, bring it across their chest, and hold the back of their hand against their near cheek — palm outward. Keep holding it there with your hand. This hand will cushion the head when they roll.
With your free hand, reach across and pull up the far knee until the foot is flat on the floor. Keep the foot on the floor — this is the kickstand that will hold the roll.
Keeping their hand against their cheek, pull gently on the raised knee to roll the person onto their side toward you. Their raised knee should contact the ground and act as a stable kickstand. Guide the head with your upper hand so it rests on their own hand — cushioned and slightly tilted back.
Adjust the upper hip and knee so they are at roughly 90-degree angles — this creates the stable "kickstand" position that keeps them on their side without you holding them there. Tilt the head back gently to open the airway and ensure the mouth is slightly open and pointing downward so fluid can drain.
Stay with the person. Watch for any change in breathing — the rate, depth, or character. Be ready to begin CPR immediately if breathing stops. The recovery position is not a "set and leave" — it is an active monitoring position while you wait for help.
When to use it
Person is unconscious and breathing normally
After successful CPR when breathing has been restored and the person is unconscious
Drowning victim who is breathing after rescue
Alcohol or drug intoxication — unconscious but breathing and at risk of vomiting
Post-seizure recovery when person is unconscious but breathing
When NOT to use it
Person needs CPR — if not breathing, CPR takes priority over positioning
Suspected spinal injury — unless the airway cannot be managed in any other way, avoid moving a person with possible spinal injury
Person is conscious — let them find their own comfortable position
Late pregnancy — roll onto the left side specifically, not either side, to avoid compressing the vena cava
Changing sides
If the person will remain in the recovery position for more than 30 minutes, roll them to the opposite side to prevent the development of pressure on the lower arm and hip. Same technique in reverse. Monitor breathing through the position change and ensure the airway remains open afterward.
