Initiation & Modes of a Ventilator | Dr. M. Rajadurai | SEMI

In this focused academic session, Dr. M. Rajadurai dives into the essential concepts behind mechanical ventilation initiation and ventilator modes explained with clarity, clinical relevance, and real-world emergency medicine context.

This lecture unpacks:
Why understanding ventilators is crucial for every emergency physician
The evolution of mechanical ventilation from negative to positive pressure systems
Core definitions: mechanical breath, variables, control types
How to choose the right ventilator mode based on patient, clinician skill, and machine capability
Confirming indications for mechanical ventilation (invasive vs non-invasive)
Step-by-step initiation: connections, circuits, self-tests, alarms
Managing oxygenation vs CO₂ issues what to tweak and why
Lung-protective strategies from the very first breath
Recognizing and resolving patient–ventilator dyssynchrony
Complete vs partial support, spontaneous vs controlled vs assist-control modes
Why no single mode is universally superior context drives decisions
Insights from ARDSNet data and reasons SAMV is not preferred in many ICUs

This talk is crafted for EM physicians, residents, and critical-care learners who want a strong foundation in ventilator logic and bedside application.
