Goal of Oxygenation and Ventilation

This lecture aims to provide a comprehensive understanding of the physiological principles, clinical objectives, and strategies for optimizing oxygenation and ventilation in critically ill patients. Participants will explore key concepts, including oxygen delivery, gas exchange, and respiratory mechanics, with a focus on evidence-based approaches to managing hypoxemia and respiratory failure.

Learning Objectives:

• Define the fundamental goals of oxygenation and ventilation in clinical practice.
• Differentiate between oxygenation and ventilation and their physiological implications.
• Identify common causes and consequences of impaired oxygenation and ventilation.
• Review key parameters used to assess oxygenation (PaO₂, SpO₂) and ventilation (PaCO₂, EtCO₂).
• Discuss strategies for optimizing oxygen delivery and improving gas exchange, including mechanical ventilation techniques, PEEP optimization, and FiO₂ titration.
• Address challenges in managing hypoxemia, hypercapnia, and ventilator-induced lung injury (VILI).
• Explore case-based applications to reinforce clinical decision-making in respiratory management.

This lecture is designed for healthcare professionals, including anesthesiologists, intensivists, and respiratory therapists, who seek to enhance their expertise in respiratory support and mechanical ventilation.
