Table 3 Targets, sensors and actuating variables in mechanical ventilation
From: SOLVe: a closed-loop system focused on protective mechanical ventilation
Target | Measurement | Controller | Actuation |
|---|---|---|---|
Oxygenation | SpO\(_2\) | SpO\(_2\) controller | FIO\(_2\), PEEP |
Ventilation | PETCO\(_2\) | PETCO\(_2\) controller | V\(_\text {T,pbw}\), \(f_\text {R}\) |
Protective volume and pressure | V\(_\text {T,pbw}\), p\(_\text {aw}\), PEEP | Pressure-regulated volume control | \(\Delta P\), V\(_\text {T,pbw}\) |
Best PEEP | \(\dot{V}_\text {aw}\), p\(_\text {aw}\), \(\hat{C}_\text {rs}\) | Automatic PEEP titration | PEEP |
