What RT Hub is
RT Hub is an educational reference and exam preparation tool built for licensed respiratory therapists, students, and other healthcare learners. It provides:
- Original practice questions aligned to NBRC TMC content areas
- Clinical calculators (tidal volume, A-a gradient, P/F ratio, MAP, dead space, RSBI, IBW, ETT depth, SaO₂ estimator)
- An arterial blood gas (ABG) interpreter
- Ventilator alarm troubleshooting flowcharts
- Reference cards for peds/NICU vent settings, ARDS management, code drug doses, and wean protocols
What RT Hub is not
- Not a medical device. RT Hub is not registered with the U.S. Food and Drug Administration (FDA) as a medical device and is not intended to diagnose, treat, cure, mitigate, or prevent any disease.
- Not a substitute for clinical judgment. Every clinical decision remains the responsibility of the licensed practitioner. Do not use RT Hub outputs as the sole basis for any patient care decision.
- Not a substitute for medical advice. If you are experiencing a medical emergency, call 911 or your local emergency number immediately. Do not rely on this app for emergency care.
- Not a substitute for institutional protocols. Always follow your hospital's or employer's approved clinical protocols, policies, and standing orders. Where RT Hub content conflicts with your institution's protocols, follow your institution's protocols.
- Not affiliated with the NBRC. The National Board for Respiratory Care (NBRC) is a registered trademark of the National Board for Respiratory Care. RT Hub is an independent study aid and is not endorsed, sponsored by, or affiliated with the NBRC. All practice items are original content authored by RYCO AI LLC and are not derived from actual NBRC examinations.
Clinical calculators and ABG interpretation
Calculator outputs and ABG interpretations are provided for educational reference only. Calculated values (e.g., IBW-based tidal volume ranges, A-a gradient, expected compensation) are based on standard published formulas and may not account for every clinical variable relevant to a specific patient. Always verify calculations against the primary source, your institution's protocols, and the specific clinical context of the patient.
Practice content accuracy
RT Hub practice items are written by a licensed respiratory therapist (RRT, RPFT) and reviewed against standard reference materials (Egan's Fundamentals of Respiratory Care, Kacmarek, and AARC Clinical Practice Guidelines). Despite this review process, errors are possible. Practice content is intended to support learning, not to be treated as authoritative reference material for patient care. If you find an error, please report it to stefan@rycoai.com.

RT Hub is not intended for direct use by patients, family members, or the general public to make decisions about their own care or the care of others. If you are a patient or a family member and have questions about respiratory care, consult a licensed medical professional.
