Understanding Occlusion Pressure (P0.1 or P100)

Welcome to Respiratory HQ, where RT students and professionals come to level up their skills and crush the NBRC credentialing exams!

In this short video, Tonya Myers-Piehl breaks down the essential concept of occlusion pressure, also known as P0.1 or P100—a key parameter used to assess ventilatory drive in mechanically ventilated patients.

💡 What You’ll Learn:

What is occlusion pressure?

How it relates to ventilator drive and patient effort

Normal occlusion pressure values (1–4 cmH₂O)

What it means when values are too high (e.g., metabolic acidosis, increased CO₂)

What it means when values are too low (e.g., oversedation, suppressed respiratory drive)

How occlusion pressure applies to weaning and ventilator liberation

🔥 Perfect for:

NBRC TMC Exam prep

NBRC Clinical Simulation Exam (CSE) prep

RT students mastering mechanical ventilation concepts

Respiratory therapists seeking real-world ventilator troubleshooting tips

Tonya explains it clearly, keeps it real, and makes sure you’re ready to recognize what matters—especially when you’re asked about weaning readiness or sedation management on your board exams.
