Drowning Response 2026: The Evidence-Based Protocol (Updated for WMS 2024 / ILCOR Utstein Terminology)

If you still use the phrase "near drowning," you are working from a vocabulary that was retired by the international resuscitation community more than 20 years ago — and rewritten again in 2024. This guide rebuilds your mental model from the current primary sources: the 2024 Wilderness Medical Society Clinical Practice Guidelines for the Treatment and Prevention of Drowning, the Joint Trauma System Drowning Management CPG (March 2025), the 2024 ILCOR Utstein update, and the 2024 AHA/AAP focused update on resuscitation following drowning. Read it once. Then update your training, your kit, and your scripts.

Why is "near drowning" no longer a valid term in 2026?

The 2003 World Congress on Drowning produced the unified ILCOR/Utstein definition that drives every modern guideline: drowning is "the process of experiencing respiratory impairment from submersion/immersion in liquid." The outcome is then classified as nonfatal or fatal — and nothing else. The 2024 WMS update reaffirmed this and named the specific modifiers that must not be used: near, wet, dry, active, passive, saltwater, freshwater, or secondary (Davis et al., WMS 2024).

Why does this matter for first responders, parents, and dispatchers? Because every retired modifier carried a treatment implication that does not exist in the evidence. There is no "saltwater versus freshwater" management split — the initial care is identical regardless of water type, salinity, or temperature (JTS Drowning Management CPG, 2025). There is no clinical entity called "dry drowning" or "secondary drowning" that should make a parent watch a coughing child for 48 hours; the legitimate concern is delayed pulmonary edema in a symptomatic patient, which presents within hours, not days (StatPearls: Drowning Clinical Management).

If your service still has standard operating procedures, training materials, or QA scripts that use any of the retired terms, fix them. The hardest correction in our own catalogue — and the reason this article exists — was retiring "near drowning" from the language we used in earlier marine guides. Vocabulary signals which evidence you actually read.

What is the "5 rescue breaths" rule and why isn't drowning CPR the same as cardiac CPR?

The mechanism is not subtle. In primary cardiac arrest the heart fails first and the brain still has oxygenated blood for several minutes; circulation is the priority. In drowning the lungs fail first; the patient becomes hypoxic, then bradycardic, then pulseless. Compressions on an unventilated drowning patient circulate deoxygenated blood. The 5-breath "recruitment" sequence opens collapsed alveoli, re-oxygenates the blood, and very often restores spontaneous circulation without compressions at all — a drowning patient who only has respiratory arrest "usually responds after a few rescue breaths" (JTS, 2025).

Two operational details follow from this:

• Do not perform the Heimlich maneuver on a drowning patient. The 2024 WMS guidelines grade this 1B against — it delays ventilation and provokes vomiting (Davis et al., 2024). Up to 65% of drowning victims who require rescue breathing vomit; 88% of those receiving chest compressions vomit. Plan for it. Roll the patient, finger-sweep visible debris, continue.
• Do not waste time trying to "drain water" from the lungs. There is no benefit and serial delays the only thing that matters: oxygen delivery (Center for Wilderness Safety). Foam at the mouth is from the lungs, not the stomach; ventilate through it.

If you carry pocket masks or BVMs in your maritime trauma kit or CPR and AED collection, they earn their place in a drowning response in a way they do not in routine cardiac arrest. Train mouth-to-mask and BVM technique with the same rigor you train compression depth.

How long can someone be submerged and still be revived?

The numbers come from large case series synthesized in both the JTS CPG and the WMS guidelines. They are the same numbers paramedics carry on laminated cards:

Cold water complicates this — favorably. The diving reflex, peripheral vasoconstriction, and the metabolic suppression of profound hypothermia have produced documented survivals from submersion times that would otherwise be terminal. The lowest core temperature ever documented in a neurologically intact survivor was 13.7 °C / 56.6 °F (JTS, 2025). That number is the reason "warm and dead" is a real rule: a drowned patient pulled from cold water is not declared dead until they are warmed.

When should you use an AED on a drowning victim — and is it safe in a wet environment?

The 2024 Wilderness Medical Society guidelines give one of their highest-evidence recommendations on this point: "incorporation of an AED in the initial minutes of drowning resuscitation should not interfere with oxygenation and ventilation. If available, an AED should be used during resuscitation of a drowning patient, and its use is not contraindicated in a wet environment" (Davis et al., 2024). The JTS CPG echoes this and adds the corollary: "Attempts to attach an AED should not be made if it delays or interferes with compressions and ventilation."

Practical steps:

1. Get the patient onto a dry, stable surface (deck, dock, hard ground).
2. Dry the chest with a towel or any absorbent cloth before placing pads.
3. Move them out of standing water and away from metallic surfaces in contact with running water.
4. Apply pads, follow AED prompts. Modern AEDs (including the units in our AED collection) are rated to operate in damp environments, but pads will not adhere or conduct correctly to a wet chest.
5. Resume the 30:2 cycle (or continuous compressions with timed ventilations if an advanced airway is in place) between shocks.

If the rescue is on a boat, the deck does not need to be bone-dry — the patient and the pad site do.

How do you safely escape a submerged vehicle?

Submerged-vehicle drownings are a distinct and survivable scenario if responders and victims know the sequence. The Canadian research that drives the modern protocols (Giesbrecht et al., cited in the 2024 WMS update) is unambiguous: doors will not open against water pressure once a few inches of water enter the cabin, and electric window motors typically continue to function for the first 30 to 90 seconds. The window — not the door — is the exit.

The corollary in coastal and maritime first aid kits is a dedicated, accessible window breaker and belt cutter. Our maritime watertight trauma kits include vehicle-egress hardware alongside hemorrhage control and airway tools because most marine medical emergencies in inland waterways are vehicle-precipitated, not boating-precipitated.

When is it appropriate to stop resuscitating a drowning patient?

The cessation thresholds in the 2024 WMS guidelines and the 2025 JTS CPG are aligned and worth memorizing because they are constantly violated in both directions — teams stop too early on cold-water victims and stop too late on warm-water arrests with terminal submersion times.

The hypothermia rule has practical teeth: a drowned child pulled from a March lake is presumed resuscitatable until rewarmed. Field teams that "call it" because the patient is cold and unresponsive are misapplying a guideline that explicitly carves out the cold-water scenario.

What happens after the patient regains a pulse — and what should the receiving hospital be ready for?

The 2024 WMS guidelines and 2025 JTS CPG converge on a small set of post-resuscitation principles. Provide supplemental oxygen at 15 L/min by non-rebreather, target SpO2 ≥ 92–96%, and place the pulse oximeter on the ear lobe or forehead because peripheral hypoperfusion makes finger probes unreliable. Avoid supraglottic airways in obtunded patients; pulmonary edema and high airway pressures defeat the seal — use BVM with good chest rise or proceed to early intubation if expertise is available (JTS, 2025).

Disposition by Szpilman grade (a clinical staging system many EDs use) is straightforward: Grade 1 or 2 patients may be observed for 4 to 6 hours and discharged with return precautions if stable. Grades 3 through 5 are admitted, often with non-invasive positive-pressure ventilation or full mechanical ventilation. Grade 6 is cardiac arrest on arrival, with the worst prognosis.

Cervical-spine immobilization is the most over-applied intervention in drowning. Routine immobilization is not indicated unless the mechanism (diving, surfing, boat accident, fall from height) suggests a cervical injury. The WMS guidelines and AHA explicitly state that spinal precautions must not delay resuscitation (Davis et al., 2024). Use a jaw thrust if you suspect injury and continue with airway and breathing.
