Note: Your three PDFs are fully image-scanned (no embedded text), so I could not extract their exact slides digitally. The explanation above covers all standard content these topics include at the level these lectures are typically taught. If any specific slide or topic from your PDFs is not covered, just ask and I'll explain it in detail!
| Your PDF | What I Covered |
|---|---|
| Modes of Mechanical Ventilation | VC-AC, PC-AC, SIMV, PSV, CPAP, PRVC - triggers/targets/cycles, when to use each |
| Ventilator Waveforms | Pressure-time, Flow-time, Volume-time waveforms; P-V loops; auto-PEEP, dyssynchrony, resistance vs compliance changes |
| Discontinuation of MV | Readiness criteria, RSBI, SBT protocol, extubation decision, cuff-leak test, post-extubation care, failure causes |
