Role-based decisions
Open the app Practical cath-lab education
Clinical judgment is built one decision at a time.
Short, realistic cases that help cath-lab professionals connect anatomy, hemodynamics, equipment and workflow—from every role in the room.
Same patient Four perspectives Real decisions
Learn the whole case. Not isolated facts.
Understand every role. Not just your assignment.
Read the rationale. Know why the answer matters.
One patient. Four perspectives.
See how every role moves the case forward.
Complete one role, return for another perspective, or advance to the next scenario. Each choice reveals a different part of the same clinical story.

Hemodynamics · 2 questions
01During right-heart catheterization, the PA pressure is 58/28 mmHg and the PCWP is 24 mmHg. Which finding best explains the pulmonary hypertension?Reveal
Best answer
Elevated left-sided filling pressure causing post-capillary pulmonary hypertension.The elevated wedge pressure points to backward transmission of pressure from the left atrium rather than an isolated pulmonary vascular problem.
02The arterial waveform suddenly appears dampened, but the patient is stable. What should the monitor professional check first?Reveal
Best answer
Inspect the pressure system for a closed stopcock, kink, air bubble or catheter damping.Confirm the accuracy of the measurement before treating the displayed number as a true hemodynamic change.
Why I’m building CathLogic360
Clinical education should make complex work feel easier.
After more than a decade in critical-care nursing, I know that confidence does not come from memorizing lists. It grows when you can connect the numbers, equipment, team and patient in front of you.
CathLogic360 is my effort to make that kind of learning practical, approachable and available in small daily pieces—especially for people who are new to the cath lab and want to understand the reasoning behind each decision.
