Cath Lab Nurse Career Guide: Skills, Salary & How to Get In (2026)

What Is a Cath Lab Nurse?

Cath lab (cardiac catheterization laboratory) nurses are specialty RNs who work in the interventional cardiology and electrophysiology procedural suite. They assist cardiologists during diagnostic and therapeutic cardiac catheterizations, percutaneous coronary interventions (PCIs / stent placements), electrophysiology studies, device implantations (pacemakers, defibrillators), and structural heart procedures (TAVR, MitraClip).

The cath lab role combines ICU-level hemodynamic monitoring with OR-level procedural support in a fast-paced, technology-intensive environment. It is one of the more specialized and better-compensated nursing roles available, and demand consistently exceeds supply in most US markets.

Cath Lab Nurse Job Duties

• Preprocedural assessment and patient education
• Conscious sedation administration and monitoring (many labs require ACLS; some require sedation credentialing)
• Hemodynamic monitoring — arterial lines, PA catheters, IABP, and Impella support
• Medication management — heparin, contrast, nitroglycerin, vasopressors, antiarrhythmics
• Scrub/circulate role during procedures (varies by lab; some facilities use cath lab techs for scrub)
• Radiation safety and protection (lead aprons, dosimetry badge, thyroid shield required)
• Post-procedure groin/radial access site management and patient monitoring
• Emergency response — a STEMI activation converts the cath lab to a high-acuity emergent setting within minutes

Cath Lab Nurse Salary (2026)

• National median: $82,000–$105,000/year
• High-cost markets (CA, NY, WA): $110,000–$145,000/year
• Florida: $80,000–$108,000/year
• Travel cath lab contracts: $2,400–$3,600/week all-in (specialty premium over standard RN travel)

Call pay (STEMI activations require on-call coverage at most facilities) adds significant income — typically $3–$8/hour for call time and a callback premium on top of base rate when called in.

Certifications for Cath Lab Nurses

• RCIS (Registered Cardiovascular Invasive Specialist) — offered by CCI; considered the gold-standard cath lab credential. Requires 2,000 hours of cath lab experience or completion of CAAHEP-accredited program. Not RN-exclusive — techs and nurses both pursue RCIS.
• CCRN — many cath lab nurses hold CCRN from prior ICU experience; considered a strong foundation credential
• ACLS — required at virtually all cath labs; STEMI activations can deteriorate rapidly
• CAVS or CEPS — structural heart (valve) and electrophysiology specialty credentials offered by CCI; valuable for hybrid OR/EP lab nurses

How to Break Into Cath Lab Nursing

Cath labs almost never hire nurses directly from medical-surgical units. The typical pathways:

1. ICU → Cath Lab — the most common transition; ICU experience builds the hemodynamic knowledge, vasopressor familiarity, and critical thinking cath labs need. 2–3 years of ICU experience is the minimum competitive baseline.
2. ED → Cath Lab — emergency nurses with STEMI experience and cardiac focus transfer well; EKG interpretation and rapid assessment translate directly
3. Step-Down / Telemetry → Cath Lab — less common but possible with strong cardiac monitoring experience (telemetry, PCU) and demonstrated interest (RCIS studying, cardiology CE)
4. Cath Lab Tech → Cath Lab RN — individuals who worked as cath lab techs before or during nursing school have a significant advantage; tech experience directly demonstrates procedural familiarity

What Cath Lab Hiring Managers Want to See

• 2+ years of ICU, ED, or cardiac step-down experience
• Current ACLS (required before starting)
• EKG interpretation proficiency — be able to discuss the basics in the interview
• Evidence of cardiac interest — cath lab CE, ACLS instructor, cardiology certifications, or RCIS studying
• Willingness to take call (nights and weekends) — STEMI call is a standard job requirement
• High-fidelity critical thinking under pressure — discuss your worst ICU or ER case in the interview

A Typical Cath Lab Shift

Most cath labs run scheduled procedures 7am–5pm with rotating after-hours STEMI call. A routine day might include 6–10 elective diagnostic caths and PCIs. During a STEMI activation, the entire team mobilizes within 20–30 minutes to get the patient to balloon inflation. The role is procedure-heavy, less "floor nursing," and very technology-focused — nurses who love gadgets, EKG rhythm interpretation, and controlled intensity usually thrive.
