Anaesthesia Coffee Break Lung compliance and the simple steps to optimise it for your patient
Jan 10, 2021
Explore the fascinating world of lung compliance and its impact on patient ventilation. Discover the distinctions between static and dynamic compliance, and learn the importance of measuring techniques. The hosts break down factors influencing lung compliance, like surfactant and chest wall conditions. Get practical tips for ventilating patients with low compliance and dynamic issues. They also discuss strategies for managing airflow during laparoscopic surgery. Tune in for a blend of theory and application in the realm of anaesthesia!

Vary Study Methods To Strengthen Memory
- Lahiru recommends studying the same topic in many formats, locations, and depths to build robust memory.
- He learned by cycling between short summaries, detailed texts, note-taking, teaching, and audio recordings.
Define And Measure Compliance Precisely
- Define compliance, measure it, and separate static from dynamic compliance when answering questions or managing ventilation.
- Use the pressure–volume slope and consider plateau vs peak pressure to interpret static and dynamic values.
Machine Readouts Show Total Respiratory Compliance
- The measured value on an anaesthetic machine is total respiratory compliance (lung plus chest wall), not lung-only compliance.
- This explains why tidal volumes require higher pressures than lung-only compliance estimates predict.
