Recognizing a heart attack on the pool deck: a lifeguard’s practical guide

Let me explain something that matters when you’re on duty. A pool isn’t just a place for splashes and sun. It’s a busy stage where symptoms can appear suddenly, and a fast, calm response can make all the difference. For lifeguards, knowing which signs point to a heart problem—and which don’t—helps you act confidently when seconds count.

Shortness of breath: the telltale clue you can’t ignore

When a heart isn’t pumping well, blood doesn’t flow as smoothly as it should. Fluid can back up into the lungs, making it hard to breathe. That trouble with breathing is what many people notice first in a heart attack. You might see someone standing still and gasping, or they could feel like they’re running out of air even with only light activity. And yes—the feeling can arrive during a jog between lanes, or it can pop up when the person is resting in the shade after a long swim.

Shortness of breath isn’t the only symptom you’ll see, but it’s the one that people often recognize as “something is seriously wrong” rather than just fatigue. You might also notice the person feels anxious or as if a heavy weight is pressing on their chest—though the chest sensation isn’t always dramatic. The key is timing: if breathing becomes noticeably labored, that’s worth fast attention, especially in a lifeguard setting where people push their bodies to the limit.

Why the other options aren’t the classic signs (and why that matters)

Let’s run through the other choices you might hear about in a quiz, just to keep you grounded in real-life scenes.

• Excessive sweating: Sure, a person can sweat a lot during activity or stress. It isn’t unique to a heart attack. Athletes sweat after a tough set of laps, and heat can cause the same clue to pop up. That’s why sweating alone isn’t enough to trigger a life-saving response. It’s the combination with breathing trouble that should raise the alarm.

• Sharp stomach pain: Digestive issues can mimic a lot of things, including abdominal cramps or gallbladder trouble. When a heart attack occurs, some people feel pain or discomfort that can radiate to the stomach, but it’s not the classic, most reliable signal on its own. If stomach pain comes with shortness of breath, that’s a call to act quickly—but don’t assume it’s only a stomach issue.

• Numbness in limbs: Nerve or circulation problems can cause tingling or numbness, but this isn’t the hallmark of a heart attack the way chest discomfort or shortness of breath is. It can point to other conditions, so it’s important to assess the full picture rather than latch onto one symptom.

In short, shortness of breath stands out as the symptom most strongly linked to a heart attack in a swimming environment. It’s not the only thing you’ll see, but it’s the sign that should trigger a rapid, organized response.

What a strong, effective response looks like on the deck

If you notice someone struggling to breathe, you’re already in a life-saving role. Here’s a practical sequence you can rely on:

• Assess the scene and the person: Ensure the area around the swimmer is safe. Check if they’re conscious, responsive, and able to speak even if it’s in short phrases.

• Call for help immediately: In most places, you should activate EMS right away. If there are others around, designate a runner to go grab a phone and alert the rest of your team while you stay with the swimmer.

• Check breathing and pulse: If the person is not breathing or is barely breathing, begin CPR right away if you’re trained. If they’re breathing but not clearly doing well, you still need rapid professional support and ongoing monitoring.

• Use an AED as soon as it’s available: If CPR is needed or if the person’s condition worsens, bring in the automated external defibrillator. Turn it on and follow the voice prompts. Don’t delay strong action while waiting for it.

• Keep the person calm and comfortable: Loosen tight clothing, sit them up if they can, or help them into a resting position that’s easy to maintain. Reassure them with simple, calm words.

• Monitor continuously: Watch for changes in breathing, level of consciousness, or responsiveness. If symptoms worsen, adjust your plan and keep EMS updated.

• Don’t give food or drink: No matter how much they complain of hunger or thirst, hold off unless medical personnel tell you otherwise.

• Aftercare handoff: When EMS arrives, give a quick, clear summary: what you observed, when it started, what actions you took, and what the swimmer’s vital signs look like now.

In the pool, timing and clarity are the two currencies that matter. Saying, “He’s short of breath and not recovering fully,” in a concise manner helps the team coordinate a fast, smooth response. And remember, as a lifeguard you’re not alone—your coverage crew and the medical team rely on your precise observations.

A quick readiness check for every shift

Staying prepared makes the moments that matter feel less chaotic. Here are a few practical reminders that fit naturally into a lifeguard’s routine:

• Training matters: Regular cardio-respiratory drills, CPR with AED, and spot checks on your equipment keep you sharp. Review the signs of heart trouble with your team so you’re all speaking the same language on a busy day.

• Equipment readiness: An accessible AED, functioning rescue equipment, and clearly marked emergency exits aren’t luxuries; they’re essentials. A quick pre-shift check can save minutes when a real call comes in.

• Clear, decisive communication: When you call EMS or coordinate with teammates, use precise phrases. Time is a resource, so skip filler words and deliver the facts—what you saw, what you suspect, and what you’re doing right now.

• Stay physically and mentally fit: A pool deck is demanding. Good stamina helps you stay calm and act quickly when you need to.

• Know your local protocols: Different communities have different rules about who should respond first and how to communicate with emergency services. A quick refresher keeps you compliant and confident.

Real-world nuance: when symptoms are not textbook

Not every heart problem looks the same, and that’s part of the challenge. Some people experience mild shortness of breath with only slight chest tightness, while others feel pressure instead of pain. A few may show fatigue, dizziness, or nausea before they justify a response as urgent. That variability is why lifeguard vigilance matters. If something still doesn’t feel right—if breathing is laborious, if someone looks pale or overwhelmed, or if you notice a sudden change in their color or pace—you treat it as a potential cardiac event. Time, in these cases, is a life ally.

A friendly analogy to keep in mind

Think of a heart attack like a blocked lane on a busy highway. When one lane is blocked, traffic backs up, drivers get anxious, and chaos can spread. In the body, this is the heart not pumping smoothly, causing congestion in the lungs and a cascade of symptoms. Your job is the highway crew: you spot the blockage, direct the responders, and keep everything moving as safely as possible until the specialists arrive. It’s a teamwork job, and every second counts.

Why this matters for you as a lifeguard

The pool is a place of trust. Swimmers, families, and joggers rely on you to keep them safe. Recognizing the most common heart-attack symptom—shortness of breath—and understanding how to act can protect lives. It’s not about memorizing a quiz answer; it’s about applying calm, practical steps when stress is high. The better you are at reading the signals, the faster you can bring help to the person who needs it.

Closing thoughts: act early, act clearly

Shortness of breath isn’t merely “one sign among many.” In the right context, it’s a red flag you don’t want to ignore. And while other symptoms exist, they don’t carry the same weight in the moment of a cardiac event. On a busy pool deck, your training—your clear assessment, your decisive calls, and your coordinated action—makes the difference between a scary moment and a life saved.

If you ever find yourself pausing to ask, “What should I do first?” remember this simple rule of thumb: when breathing becomes a struggle, treat it as urgent. Call for help, get the AED, begin a steady course of care, and stay with the person until help arrives. That sequence keeps the focus where it belongs—on safeguarding lives and keeping swimmers safe.

After all, whether you’re on a quiet afternoon shift or a crowded weekend, you’re part of a system that looks out for others when they need it most. And that’s something worth being prepared for, every single day.
