Method Matters More Than Mode
- The mode name (APRV) is less important than the method used to set the ventilator; TCAV describes the intended method better.
- Time-targeted control of inflation and release exploits lung viscoelasticity more than pressure-focused approaches.
Use Time To Recruit And Stabilize
- TCAV uses prolonged inspiratory time to let distal airways equilibrate and recruit viscoelastic lung units.
- Expiratory time is shortened to avoid alveolar collapse and is personalized by watching the flow decay to ~75% of peak.
Practical Default Timings
- For routine (non-rescue) use they set Thigh around 4–6 seconds to avoid hypocarbia in relatively normal lungs.
- Tlow is then short (roughly 0.5–0.6s for normal lungs) and always indexed to the 75% flow decay rule.
