Study Notes
Fatty Infiltration of Pharyngeal Wall
- Fatty infiltration of the pharyngeal wall leads to increased pharyngeal wall compliance
- This results in difficulty in ventilating by face mask
- Metabolic changes occur, including:
- Increased oxygen consumption (↑ O₂)
- Increased carbon dioxide production (↑ CO₂)
- Chronic hypercarbia may occur, leading to:
- Renal compensation
- Altered COâ‚‚ sensitivity

Description
This quiz covers the effects of fatty infiltration of the pharyngeal wall on ventilation, including increased pharyngeal wall compliance and metabolic changes. It also explores the consequences of chronic hypercarbia.
