Anaphylaxis at the pool: a lifeguard’s quick, practical guide

Let’s start with the simple truth: anaphylaxis is a severe, potentially life-threatening allergic reaction that can move fast. On a crowded pool deck, where things happen in a heartbeat, recognizing and acting on a true anaphylactic reaction can be the difference between a close call and a tragedy. This isn’t about panic; it’s about clarity, calm action, and teamwork.

What is anaphylaxis, really?

Think of anaphylaxis as the body’s alarm system gone into overdrive. A normal allergic reaction might give you a few hives or a runny nose. Anaphylaxis, by contrast, can involve the throat swelling, trouble breathing, a sudden drop in blood pressure, and skin changes like widespread hives. It can come on within minutes of exposure to the trigger and can deteriorate quickly if not treated. The stakes are high, which is why lifeguards train to treat it as an emergency from the first sign.

Here’s the thing about the cues: some people may start with itching or a few hives, while others feel dizzy, have abdominal distress, or hear a whistling breath. That range means you listen carefully, not dismiss anything as “not serious.” If breathing is affected, if the throat or tongue swells, or if the pulse drops and someone looks faint, that’s a red flag. When you’re on pool duty, you’re not just watching water—you're watching signs that someone’s body is fighting a threat to its airway and circulation.

Spotting the signs quickly

Let’s map it out in plain terms, so you can act without hesitation:

• Breathing changes: wheezing, tight feeling in the chest, shortness of breath, noisy breathing.

• Airway swelling: the tongue or throat feels thick, speech becomes slurred or muffled.

• Skin signals: widespread hives, widespread redness, or swelling beyond a local spot.

• Circulation issues: dizziness, light-headedness, sudden pale or clammy skin, a weak or fast pulse.

• Gut symptoms: nausea, vomiting, or diarrhea, especially with other symptoms.

• General sense: anxiety, a sense of impending doom, confusion, or unusual fatigue.

Important: a mild allergic reaction may cause some itching or swelling at a spot, but anaphylaxis usually involves multiple body systems and rapid changes. If you’re unsure, err on the side of caution. When a reaction starts to hit the airway or the heart, seconds count.

Immediate actions you should take

Let me explain the flow that lifeguards rely on when anaphylaxis is suspected. It’s a short, repeatable sequence you can run through almost by habit:

• Call for help right away. Notify EMS without delay. Put the call on speaker if you’re coordinating a team response and the person needs monitoring while help arrives.

• Check airways, breathing, and circulation. If the person is conscious and able to speak, keep them calm but monitor every breath. If they become unresponsive, begin CPR and be ready to use an AED if you’re trained to do so.

• Administer epinephrine if it’s available and you’re trained to use it. For many lifeguard teams, epinephrine auto-injectors are part of the kit. Use the device as directed on the label, usually into the outer thigh, and do not delay transport for medication to take effect. After injecting, call for advanced help immediately.

• Position and comfort. If there’s no suspicion of spinal injury, have the person lie flat with legs elevated slightly unless this worsens breathing. Loosen tight clothing, keep them warm, and avoid giving food or drink.

• Monitor and reassess. Watch for changes in breathing, color, or responsiveness. If symptoms worsen or don’t improve within a few minutes, a second dose of epinephrine may be indicated, and EMS should continue the assessment.

• Prepare for the next steps. When EMS arrives, hand over what you observed: timing of symptoms, what you saw, medications given, and how the person responded.

The role of epinephrine: why timing matters

Epinephrine is a critical, time-sensitive intervention. It counteracts the reaction by opening the airway, tightening blood vessels to raise the blood pressure, and reducing swelling. The takeaway is simple: if you suspect anaphylaxis, don’t wait for all the symptoms to line up perfectly before acting. Treat quickly, then let the medical team take over. If you’re at a facility and trained to give a second dose, that option is there, but follow your team’s guidelines and local protocols.

Tricks of the trade on pool decks

A few practical points to keep everyone safer around water:

• Have a clear, rehearsed response plan. Your team should know who calls for EMS, who administers any necessary medications, and who keeps the patient safe and comfortable.

• Keep emergency meds accessible and labeled. If an auto-injector is part of the kit, check expiration dates and accessibility as part of routine checks.

• Maintain visibility and a calm presence. Clear communication helps a frightened swimmer or spectator stay calm, which in turn keeps breathing easier for the patient.

• Don’t overlook triggers. Food on a snack table, a bee that buzzes near a deck chair, or latex-free gloves that someone reacts to—these little details matter. The more you know about potential triggers in your venue, the quicker you’ll react.

• Create inclusive, visible alerts. Signage and staff explaining: “If you or your child has known severe allergies, tell us right away so we can help you prepare.” Accessibility of help is part of safety.

What to watch for beyond the obvious

Sometimes anaphylaxis can show up in surprising ways. A person might look anxious or pale, feel nauseous, or have a sudden drop in energy, and you’ll be thinking through the checklist. Don’t ignore those signals, especially if they’re paired with trouble breathing, throat tightness, or swelling. It’s not a crime to ask a few quick questions: “Do you have an allergy? Are you carrying an auto-injector? Is this your first reaction?” These questions aren’t intrusive—they’re essential for quick, accurate triage.

Training habits that pay off

If you’re on the pool deck often, you’ll appreciate a steady cadence of readiness. Here are some simple, effective habits:

• Regular drills that simulate tracing a reaction from first sign to EMS arrival.

• Quick-reference cards or posters by the lifeguard station that list symptoms and steps.

• Team roles that stay consistent so someone knows exactly what to do without waiting for direction.

• Debriefs after any incident to capture what went well and where to tighten the response.

• Cross-training with local EMS or medical staff to stay current on best practices and local regulations.

A relatable scenario to keep it real

Imagine it’s a busy Saturday afternoon. A family near the main pool closes in, the kids splashing and the screen door rattling with the day’s noise. A swimmer suddenly clutches their chest, starts wheezing, and tells someone they’re allergic to something they just ate at the snack stand. Within moments, the throat tightens a bit, and you notice rapid breathing. You don’t pause. You call for help, quickly check their breathing, and administer an epinephrine auto-injector if your team protocol allows it. You monitor their complexion, greet EMS with a succinct report, and keep them flat and comfortable until the paramedics arrive. The whole deck stays focused, the scene stays calm, and everyone knows their role. When help arrives, you hand over your notes: what happened, what you did, and how the person responded.

This is the rhythm you want on a crowded day: be observant, be ready, and act decisively. It’s not about a dramatic show of heroics; it’s about clear thinking under pressure, teamwork, and the readiness to protect lives when the clock is ticking.

A quick takeaway to keep in your back pocket

• Anaphylaxis is a severe, rapid allergic reaction that can threaten life if not treated quickly.

• Recognize multi-system signs early: breathing changes, airway swelling, skin reactions, dizziness, or abdominal distress.

• Act fast: call EMS, assess airway and breathing, administer epinephrine if available and you’re trained, position the person, and monitor.

• Have a plan, have meds accessible, and practice the teamwork that makes a real difference.

• Understand common triggers in aquatic settings and how to minimize exposure and risk.

Stay curious, stay prepared

On a pool deck, you’ll meet all kinds of people, with all kinds of stories behind every reaction. The better you are at reading the signs and acting confidently, the more you’ll help keep everyone safe. If you’re ever unsure, it’s okay to pause and verify with a teammate or supervisor—safety isn’t about bravado; it’s about doing the right thing, right now.

By keeping these principles in mind, you’ll move through shifts with a steady rhythm, ready to respond when seconds count. And that readiness—that calm, practiced competence—itself becomes part of the safety net the pool relies on. If you’re on duty and see warning signs, you’ll know what to do, you’ll do it, and you’ll help protect a life that could depend on your quick actions.
