Respiratory Foundations
Build the anatomy, physiology, examination, respiratory support, blood-gas, and imaging framework needed to understand pediatric respiratory disease.
Learning Path
Work through the modules in sequence or jump directly to the concept you need. The learning path progresses from structure to function, bedside assessment, respiratory support, and diagnostic interpretation.
Module 01
Build a mental map of the pediatric respiratory system from the upper airway to the alveoli, pleura, diaphragm, and pulmonary vasculature.
Core concepts
Airways · Lung lobes · Pleura · Diaphragm · Pulmonary vasculature
Module 02
Understand how air moves, how gas exchange occurs, and how airway resistance, compliance, ventilation, and perfusion shape respiratory physiology.
Core concepts
Ventilation · Compliance · Resistance · V/Q · Shunt · Dead space
Module 03
Learn to recognize respiratory distress, localize abnormal breath sounds, and identify the clinical transition from increased work of breathing to respiratory failure.
Core concepts
Work of breathing · Breath sounds · Distress · Respiratory failure
Module 04
Compare pediatric oxygen-delivery devices and respiratory-support modalities while learning what each device actually provides and when escalation is needed.
Core concepts
Nasal cannula · Masks · HFNC · CPAP · BiPAP · Mechanical ventilation
Module 05
Interpret respiratory acid-base physiology and understand what arterial, venous, and capillary blood gases can—and cannot—tell you.
Core concepts
ABG · VBG · Capillary gas · pH · CO₂ · HCO₃⁻
Module 06
Develop a systematic approach to respiratory imaging and recognize foundational lung ultrasound findings before applying them to individual diseases.
Core concepts
Chest X-ray · CT · Lung sliding · A-lines · B-lines · Consolidation
Why start here?
Stridor, wheezing, hypoxemia, hypercapnia, air trapping, and abnormal imaging are not isolated facts. Each reflects a change in respiratory anatomy or physiology. These modules provide the framework for connecting those findings to the disease modules throughout PediAtlas.
