Every RRT module, previewed free.
Each module rebuilds a high-yield RRT topic from the pathophysiology up, then tests it with questions that explain why the other three answers are traps. The opening concept is free; members unlock the rest.
Timed 185-question exam
A full 4-hour simulation in the new RTE format, pulled from all 29 modules — answer sheet, flagging, pass/fail result, and a weak-area report.
Arterial Blood Gas Interpretation
A repeatable four-step read of any ABG — acid-base status, compensation, oxygenation, and the clinical story that produced it.
Mechanical Ventilation Fundamentals
Modes, initial settings, and the pressure readings that tell you whether the problem is the circuit, the airway, or the lung.
Oxygen Delivery Devices
Low-flow versus high-flow logic, deliverable FiO2 ranges, and how to choose the device that matches the patient's inspiratory demand.
Pulmonary Function Test Interpretation
How to sort obstructive from restrictive patterns, grade severity, and read the bronchodilator and diffusion results that follow.
Airway Management: Intubation, Tracheostomy & Suctioning
Tube selection, placement confirmation, cuff management, suctioning technique, and the emergency airway decisions the exam asks about most.
Mechanical Ventilation: Monitoring, Graphics & Waveforms
Reading scalars and loops to localize a problem — resistance versus compliance, auto-PEEP, asynchrony, and leaks — before touching a setting.
Ventilator Weaning, Liberation & Extubation
Readiness criteria, the spontaneous breathing trial, the numbers that predict success, and how to recognize post-extubation failure early.
Noninvasive Ventilation, CPAP & BiPAP
Who benefits, who must be intubated instead, how to set IPAP and EPAP, and how to tell in two hours whether NIV is working.
Patient History, Chart Review & Physical Assessment
Building the clinical picture before you touch a device — history, vitals, inspection, auscultation, and the lab values that change respiratory decisions.
Pharmacology: Bronchodilators, Steroids & Adjunct Agents
Drug classes by mechanism, dosing, side effects, and the exam's favorite question: which agent for this patient, right now.
Chest Radiograph & Imaging Interpretation
A systematic read of the portable film — line and tube position, the classic pathology patterns, and what imaging can and cannot answer.
Humidity, Aerosol Therapy & Bland Aerosol
Choosing humidifiers and nebulizers, particle size and deposition, delivery technique, and the troubleshooting the exam expects.
Bronchial Hygiene, Lung Expansion & Hyperinflation Therapy
Secretion clearance and lung expansion therapies — who needs which, how to judge effectiveness, and when to stop.
Emergency Care, ACLS, Resuscitation & Transport
The therapist's role in codes: high-quality CPR metrics, airway and ventilation during arrest, capnography feedback, and safe transport.
Neonatal & Pediatric Respiratory Care
Delivery room resuscitation, surfactant, neonatal ventilation targets, and the pediatric airway differences that change every decision.
Hemodynamic Monitoring & Cardiac Assessment / ECG
Reading pressures and rhythms the way a therapist must: what the number means, what it changes, and which rhythm needs action now.
Infection Control, Sterilization & Equipment Quality Control
Isolation precautions, disinfection levels, equipment processing, and the quality control checks the exam expects you to perform and interpret.
Chronic Disease Management, Home Care & Pulmonary Rehab
Long-term oxygen criteria, home equipment selection, sleep-disordered breathing, patient education, and rehabilitation outcomes.
Equipment Assembly & Troubleshooting
The NBRC tests equipment failure constantly: what breaks, what the patient looks like when it breaks, and the fix you perform before you call anyone.
Medical Gas Supply & Cylinder Systems
Cylinder duration math, safety index systems, regulators, and bulk supply — the calculation questions you can guarantee will appear.
Sleep-Disordered Breathing & Titration
Obstructive versus central events, AHI severity, and how a CPAP or bilevel titration is actually driven overnight.
Bronchoscopy & Special Procedures
Assisting with bronchoscopy, thoracentesis, chest tubes, and arterial lines — the setup, the monitoring, and the complication you must catch.
Protocols, Documentation & Professional Ethics
Therapist-driven protocols, charting that holds up, scope of practice, and the ethics questions the NBRC scores as clinical judgment.
Capnography & Bedside Monitoring
Waveform capnography, the PaCO2–EtCO2 gradient, pulse oximetry limits, and the monitors that tell you the truth before the gas does.
Specialty Gas Therapy: Heliox, Nitric Oxide & Hyperbarics
When density, selective vasodilation, or dissolved oxygen is the therapy — indications, delivery, monitoring, and the toxic endpoints.
Tracheostomy & Long-Term Airway Care
Tube anatomy, cuff management, speaking valves, decannulation, and the emergency that kills — a dislodged fresh trach.
Laboratory Data & Microbiology Interpretation
Electrolytes, CBC, coagulation, cardiac and sputum data read the way a respiratory therapist has to read them.
Patient Transport & Disaster Response
Intrahospital and flight transport planning, gas supply math under pressure, and triage when resources run out.
Pulmonary Rehabilitation, Education & Smoking Cessation
Exercise prescription, breathing retraining, adherence teaching, and the cessation counseling the exam expects you to deliver.
