Infection Control, Standard Precautions, and Patient Safety

Why Infection Control Matters for EKG Technicians

As an EKG technician, you touch patients repeatedly throughout the day—placing electrodes on bare skin, handling lead wires, and moving from room to room. Each contact is an opportunity to transfer microorganisms between patients, between patient and technician, or between equipment and patient. Healthcare-associated infections (HAIs) cause serious harm and are largely preventable. Your first duty to every patient is to arrive at the bedside as safe as possible.

Standard Precautions: The Foundation

Standard precautions apply to every patient, every time, regardless of diagnosis or appearance. They are based on the principle that blood, all body fluids, non-intact skin, and mucous membranes may contain infectious agents. The core elements relevant to EKG practice are:

• Hand hygiene — the single most effective measure to prevent HAIs
• Personal protective equipment (PPE) — gloves at minimum for all patient contact; add gown, mask, or eye protection when splash or spray is possible
• Safe handling of equipment — clean and disinfect reusable lead wires between patients according to facility policy
• Respiratory hygiene/cough etiquette — offer a mask to coughing patients
• Safe injection practices — not directly in scope for EKG techs, but awareness matters

The WHO Five-Moment Hand-Hygiene Protocol

The World Health Organization identifies five moments when hand hygiene is required:

1. Before touching a patient

2. Before a clean or aseptic procedure (e.g., placing electrodes on abraded skin)

3. After body-fluid exposure risk

4. After touching a patient

5. After touching patient surroundings

For an EKG procedure, you will typically perform hand hygiene at moments 1 and 4 at minimum. Use alcohol-based hand rub (ABHR) when hands are not visibly soiled; use soap and water when hands are visibly dirty or after caring for a patient with Clostridioides difficile (C. diff), because alcohol does not reliably eliminate C. diff spores.

Correct technique with ABHR: Apply the product to the palm of one hand, rub hands together covering all surfaces—palms, backs, between fingers, thumbs, fingertips, and wrists—until dry (at least 20–30 seconds). With soap and water, lather for at least 20 seconds, rinse, and dry with a single-use towel; use the towel to turn off the faucet.

Transmission-Based Precautions

When standard precautions alone are not sufficient, the CDC describes three categories of transmission-based precautions:

| Category | Pathogen Examples | Key PPE Added | Room Requirement |

|---|---|---|---|

| Contact | MRSA, VRE, C. diff, scabies | Gloves + gown on room entry | Private room preferred |

| Droplet | Influenza, pertussis, mumps | Surgical mask within about 3 feet of patient | Private room preferred |

| Airborne | Tuberculosis, measles, varicella | Fit-tested N95 respirator | Negative-pressure room required |

A patient may be on more than one precaution type simultaneously.

Donning and Doffing PPE Correctly

Putting PPE on (donning) and taking it off (doffing) in the right sequence prevents self-contamination. A single error—such as touching your face before removing gloves—can transfer pathogens directly to mucous membranes.

Donning sequence (contact precautions): gown → mask or respirator → eye protection if needed → gloves last.

Doffing sequence (contact precautions): gloves first → eye protection → gown → mask or respirator last. Remove each item away from your body and dispose of it in the appropriate waste container before leaving the patient area. Perform hand hygiene immediately after removing each piece of PPE and again after all PPE is removed.

Critical rule: Never touch your face, eyes, or neck with contaminated gloves. Never remove your gown before your gloves—doing so drags contaminated glove material across your arms and hands.

Electrode-Site Skin Preparation and Waste Disposal

Proper skin preparation for a 12-lead EKG involves light abrasion with a prep pad or dry gauze and, if needed, clipping excess hair. This can create micro-abrasions, so always wear gloves. Used prep pads, electrode tabs, and gauze are contaminated and must be disposed of in accordance with facility policy—typically in a regular waste container unless visibly bloody, in which case they are treated as regulated medical waste.

Reusable lead wires should be wiped down with a hospital-approved disinfectant wipe after each patient. Never share electrodes between patients.

Patient Safety During the EKG Procedure

• Confirm patient identity using two identifiers before touching the patient.
• Explain the procedure before applying electrodes to gain cooperation and reduce anxiety.
• Ensure call-light access and bed rails are in the safe position throughout.
• Observe the patient for distress during and after the procedure; report any complaints of chest pain, shortness of breath, or skin reactions immediately.
• Document the time of the tracing and any patient condition that might affect the recording.

Scope of Practice

Your role is to acquire a high-quality EKG tracing safely. You do not interpret findings, adjust medications, or diagnose. If you observe an alarming rhythm or a patient in distress, stop, ensure patient safety, and notify the nurse or provider immediately.
