Targeting Schemes

A Targeting Scheme is "A model of the relationship between operator inputs and ventilator outputs to achieve a specific ventilatory pattern, usually in the form of a feedback control system" [1]. The targeting scheme describes the main functionality of a ventilator mode and helps one differentiate modes of mechanical ventilation. 

This is not only helpful when classifying a mode for academic purposes, but the knowledge of a targeting scheme is beneficial when selecting a ventilator mode to best match its capabilities to the clinical goals of mechanical ventilation. 

There are seven different targeting schemes:

1. Set-point
2. Dual
3. Servo
4. Bio-variable
5. Adaptive
6. Optimal
7. Intelligent

In my next video series I will be over-viewing each targeting scheme (except Bio-variable) starting with the most basic 'Set-Point' then progressing based on engineering hierarchy & complexity. 

Below are my first two videos:

1. Introduction to targeting Schemes
2. Set-Point Control
