5 Questions
What is a feature of the pharyngeal wall mentioned?
Fatty infiltration
What challenge is associated with ventilation using a face mask?
Difficulty in ventilation
What is the effect on O₂ consumption and CO₂ production?
Increased O₂ consumption, increased CO₂ production
What condition might be present with renal compensation and altered CO₂ sensitivity?
Chronic hypercarbia
What is a characteristic change in pharyngeal wall compliance?
Increased compliance
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 CO₂ sensitivity
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.
