When an employee collapses and no one nearby has been trained, the first minutes tend to disappear into confusion, hesitation, and waiting. That gap matters because a person in sudden cardiac arrest has only minutes before brain injury becomes likely, and an ambulance rarely arrives inside that window. Untrained employees in a medical emergency are not usually careless. They are unsure what to do, afraid of making things worse, and assume someone else is better qualified.

This article covers what typically goes wrong, the myths that keep people from acting, what employers are exposed to, and how a practical training plan closes the gap. The central point is simple: the people who are present when an emergency starts are the ones who determine what happens next.

Why Cardiac Arrest and Other Emergencies Cannot Wait for EMS

Sudden cardiac arrest is an electrical malfunction that makes the heart quiver or stop, ending blood flow to the brain and other organs. It is not the same as a heart attack, which is a blockage that reduces blood flow to the heart muscle. A heart attack victim is usually awake and in pain. A person in cardiac arrest is unresponsive and not breathing normally, and without help they will die.

Survival depends on how quickly CPR and defibrillation begin. The American Heart Association (AHA) publishes annual statistics in its Heart Disease and Stroke Statistics update, and the pattern is consistent across years: most out-of-hospital cardiac arrest victims do not survive, and bystander CPR is associated with substantially better odds than no bystander action. Check the AHA's most recent update for the current figures before you quote them in your own safety materials.

Response time is the other variable. EMS arrival varies by location, and rural and suburban workplaces across the Midwest can wait longer than offices in a dense urban core. Your local dispatch center or county EMS agency can tell you typical response times for your address, and that number is worth knowing. Every minute before the ambulance arrives is a minute your own staff must cover.

Cardiac arrest is not the only emergency that follows this pattern:

  • Severe bleeding can cause shock within minutes unless someone applies direct pressure or a tourniquet.
  • Choking blocks the airway and calls for abdominal thrusts or back blows right away.
  • Anaphylaxis can close the airway and drop blood pressure, and it needs epinephrine and a 911 call.
  • Seizures require protecting the person from injury and timing the event.
  • Diabetic lows can lead to unconsciousness if sugar is not given in time.

In each case, a basic response in the first few minutes changes the outcome.

What Untrained Employees Typically Do Wrong

The most common failure is no action at all. People freeze, or they assume someone else has already called 911. This is the bystander effect: the more people who witness an emergency, the less responsible each individual feels, so everyone waits for someone else to act. A crowded break room can be worse than an empty one.

When someone does call, the call often loses time. Dispatchers need an exact location, and untrained callers frequently omit the building entrance, floor, or suite number, or they cannot explain how to reach the person inside a large facility. Crews then lose minutes searching. Nobody sent to the loading dock to meet them makes it worse.

Well-meant actions can also cause harm or waste time:

  • Moving the person when it is not necessary, which can worsen a spinal injury and delays care.
  • Offering food or drink to someone who is confused, drowsy, or seizing, which risks choking. (A conscious, cooperative person with a diabetic low is a different case, and trained staff know the distinction.)
  • Compressions that are too shallow or too slow, which do not circulate enough blood to matter. Untrained rescuers often press lightly because they fear hurting the person.
  • Stopping compressions too often to check for signs of life.

Then there is the defibrillator. Many employees do not know their workplace has an automated external defibrillator (AED), where it is kept, or that it is designed for lay users. An AED analyzes the heart rhythm and gives voice instructions, and it will deliver a shock only if one is needed. A device mounted on a wall that nobody uses delivers no benefit at all.

Myths That Keep Employees From Acting

Hesitation is often rooted in beliefs that are wrong. Correcting them is part of any good training program.

"I could hurt someone with CPR."

Compressions can break ribs, and trained instructors say so plainly. But a person in cardiac arrest is already dying, and a rib injury is survivable. The greater harm is doing nothing.

"Only healthcare workers can use an AED."

This is false. AEDs are built for untrained bystanders, with spoken prompts and pictures guiding each step. The device will not shock a person who does not need it.

"I will be sued if I help."

Fear of lawsuits is common, but Good Samaritan laws exist in every state to protect people who give emergency aid in good faith. The details vary, including who is covered and what conduct is excluded, and some states address AED use separately. This is not legal advice. Read the statute for your own state, or ask your attorney, and share the plain-language summary with staff.

"Mouth-to-mouth is required."

For an adult who collapses outside a hospital, the AHA recommends Hands-Only CPR: call 911, then push hard and fast in the center of the chest. This lowers the barrier for people who are uncomfortable giving breaths. There are caveats. Children, infants, and drowning victims usually need rescue breaths because their arrests more often stem from a lack of oxygen, and a trained rescuer should give breaths when able. Standard CPR with breaths is still taught in certification classes for that reason.

The Employer Side: Obligations, Liability, and Real Costs

Federal workplace rules address this directly, though not as broadly as many employers assume. As of 2026, OSHA's first aid standard, 29 CFR 1910.151(b), says that when there is no infirmary, clinic, or hospital in near proximity to the workplace, a person or persons must be adequately trained to render first aid. The standard does not spell out CPR for every workplace, and OSHA has interpreted "near proximity" in terms of how quickly care can be reached, which it has tied to a few minutes for life-threatening injuries. Review the current text and OSHA's interpretation letters, and confirm how they apply to your site.

Some sectors have firmer requirements. Childcare licensing rules in many states require staff to hold current pediatric CPR and first aid certification, and healthcare employers typically require BLS. Your state licensing agency and your own accreditation standards define what is mandatory for you.

The costs of being unprepared are harder to price. They include:

  • Lost productivity after an incident, sometimes across an entire shift or site.
  • Workers' compensation exposure when an injury is made worse by a slow or incorrect response.
  • The effect on coworkers who watched a colleague die and wonder whether they could have helped.

Cost figures vary widely by industry and incident, so rely on named sources, such as the Bureau of Labor Statistics or the National Safety Council, rather than rules of thumb.

One practical step: ask your insurance carrier. Many carriers offer safety guidance, loss-control consultations, or training recommendations, and some factor safety programs into underwriting. A short conversation with your broker costs nothing.

Building a Prepared Workplace: Training, AEDs, and Emergency Plans

Preparedness has four parts, and none of them is complicated.

Match training to the role

General staff usually need a CPR/AED and First Aid course. Healthcare providers need BLS, which covers team-based resuscitation and advanced airway basics. Childcare workers need pediatric content, and anyone near first-responder work, such as security or facilities staff, may need additional coverage. One course will not fit everyone.

Cover every shift and location

A single trained person is a single point of failure. Vacations, nights, weekends, and remote sites all leave gaps. Aim for several trained employees on every shift at every location. Certifications generally need renewal every two years, though providers vary, so keep a simple tracker of expiration dates and schedule renewals before they lapse.

Place and maintain AEDs

An AED should be reachable within a few minutes of any point in the building, which in a large facility means more than one device. Mount them in visible, unlocked locations with clear signage, and check batteries and pads on a set schedule. Pads and batteries expire, and a dead device is worse than no device because people assume it works. Check your state's AED requirements for registration and medical oversight rules.

Write a short emergency action plan

Assign roles in advance: who calls 911, who meets EMS at the entrance, who retrieves the AED, who clears the area. Put the exact address and entrance instructions on a card by every phone. Then run a drill, because a plan that has never been practiced tends to fall apart under stress.

Midwest CPR Center can deliver on-site group classes and blended options that combine online learning with hands-on skills sessions, which helps when schedules are tight.

What Trained Employees Do Differently: A Walkthrough

Suppose a coworker slumps in the break room and slides off a chair. A trained employee follows a sequence that has become automatic:

  1. Check the scene and the person. Tap the shoulders, shout, and look for normal breathing for no more than ten seconds.
  2. Send people with specific tasks. Point at one person: "Call 911 and give the street address and entrance." Point at another: "Get the AED."
  3. Start compressions. Place the heel of one hand on the center of the chest, the other hand on top, and push straight down.
  4. Turn on the AED when it arrives. Expose the chest, apply the pads as pictured, let the device analyze, and clear the person before a shock is delivered.
  5. Resume compressions immediately after the shock, continuing until EMS takes over or the person responds.

The specifics are what classes drill. As of 2026, AHA guidelines call for compressions at a rate of 100 to 120 per minute and a depth of at least 2 inches (about 5 cm) for adults, with full chest recoil between pushes. Confirm the latest guideline update with the AHA, since your instructor will teach from the current version. Students also practice hand placement and AED pad positions, which differ for adults, children, and infants.

The real difference is confidence. Pressing on a manikin with a feedback device shows you, in real time, whether your depth and rate are correct. Reading a pamphlet or watching a video cannot do that, and muscle memory is what carries people through the first frightening seconds.

From Hesitation to Action: Review Your Coverage This Month

A workplace medical emergency exposes whatever preparation was or was not done beforehand. Training turns hesitation into action, and a few steps are enough to start: count how many trained people are on each shift, find your AEDs and check their pads, and write down who does what when someone collapses.

Don't wait until an emergency happens. Equip yourself and your team with life-saving skills today. Schedule your CPR certification class now and gain the confidence to respond when every second counts.
