The physician performs the procedure, but the case doesn't happen safely without a coordinated technologist team. Most new techs learn all three seats, and being strong in every one is what makes you valuable.
Scrub
Sterile, at the table with the physician. You manage the catheters, wires, balloons, and stents — passing the right device at the right moment. The best scrub techs anticipate the next step and have the device ready before it's asked for. It demands sterile discipline, manual precision, and total attention to the case.
Circulate
Running the room. Medications, supplies, documentation, and patient safety all flow through the circulator. You're the link between the sterile field and everything outside it — getting what the table needs fast, charting the case, and keeping an eye on the patient as a whole.
Monitor
Operating the hemodynamic recording system and reading the pressure waveforms in real time. You call out rhythm changes and pressure findings, and you're often the first to notice when something shifts. This is where rhythm interpretation and hemodynamics knowledge earns its keep.
A case, start to finish
A patient comes in for a diagnostic angiogram that may become an intervention. The team preps and drapes; the circulator confirms the patient, meds, and consent. The physician gains access; the scrub tech hands up the wire and catheter and manages the table. The monitor tech watches the pressures as the catheter advances, flags the waveform transitions, and records the run. If a blockage needs treating, the scrub tech readies the balloon and stent while the monitor tech watches the rhythm and the circulator manages meds and timing. Everyone's role interlocks — that's the job.
The part that surprises people
It's genuinely a team sport, not a support role for the physician. On a good team, the techs are reading the case as it unfolds and staying a step ahead — and when a STEMI rolls in at 3 a.m., that coordination is the difference.
The skills that matter most
- Rhythm and hemodynamics — you have to read them live, especially in the monitor seat.
- Sterile technique — non-negotiable at the table.
- Anticipation — watching the case, not just your tray.
- Closed-loop communication — reading numbers back, confirming doses, no ambiguity.
- Calm under pressure — a steady tech makes the whole room safer.
The monitor seat starts with rhythms.
