Episode notes
ABG Machine Understanding
- Understand how ABG values are obtained, not just interpreted.
- Study the Clark electrode diagram, as labeling may be required in exams.
Troubleshooting Arterial Lines
- Troubleshoot arterial line issues like dampened traces.
- Consider factors such as tubing length and air bubbles.
Mastering the Wheatstone Bridge
- Understand the Wheatstone bridge concept for arterial blood pressure measurement.
- Practice drawing and explaining its components for exams.
