Q and A:



This presentation focuses on the fundamentals of mechanical ventilation and practical ventilator management in emergency and critical care settings. The session explored the physiology of breathing, the differences between normal ventilation and positive pressure ventilation, and the core principles of oxygenation and ventilation.



Key topics included:



* Respiratory physiology and gas exchange

* Ventilator modes and how breaths are triggered and delivered

* Resistance and compliance

* Volume vs pressure controlled ventilation

* Lung protective ventilation strategies

* The role of tidal volume, respiratory rate, FiO₂ and PEEP

* Shunt physiology and oxygenation

* Practical approaches to ventilator setup and troubleshooting



The session aims to simplify ventilator management into understandable physiological concepts, helping clinicians build confidence in approaching critically ill ventilated patients in the emergency and retrieval environment.
