RT Hub is the pocket toolkit for respiratory therapists — a fast ABG interpreter, 9 clinical calculators, vent troubleshooting guides, and TMC/CSE exam prep in one place.
RT Hub was built during 12-hour shifts. Every tool exists because I needed it at 3 AM and didn't want to open five different tabs to get an answer.
Enter pH, PaCO₂, HCO₃, PaO₂, FiO₂. Get acid-base classification, compensation status, and A-a gradient in seconds — with the reasoning shown.
Pick an alarm — High Peak, Low Volume, Auto-PEEP, Loss of Wave — get a guided step-by-step plan. Rooted in AARC guidelines.
Tidal volume, A-a gradient, P/F ratio, MAP, dead space, RSBI, IBW, ETT depth, SaO₂ estimator. Always free.
Original, RRT-authored practice items across all TMC content areas. Weakness detection, spaced review, mock exams. Not affiliated with NBRC.
See where you're strong and where you're weak. Daily streak, topic mastery, study time — all in one dashboard.
Peds/NICU vent settings, ARDS management, code drug doses, wean protocols. Fast lookup during a shift.
Type in the values. Get the primary disturbance, compensation status, A-a gradient, and reasoning — before you finish typing the note.
When the alarm goes off, tap the alarm type. RT Hub walks you through the guided checklist — DOPE for peds, patient-vs-vent for adults — one step at a time.
Study by topic, run a diagnostic, take a mock exam, or drill your weakest areas. Every question is original and written by a working RRT.
Every calculator, every alarm flowchart, every practice question — written by a licensed respiratory therapist working in acute care. If it's in RT Hub, it's because I use it.
