Simplifying Mechanical Ventilation – Part 2: Goals of Mechanical Ventilation & Factors Controlling Oxygenation and Ventilation
In part 1, we discussed that the ventilator can deliver 3 types of breaths: controlled, assisted or spontaneous breaths. These breaths can be delivered either by a set pressure or a set tidal volume. Then we closed with a discussion of the common ventilator modes, which is simply just combining all these types of breaths together.
There are many aspects to consider in post-intubation management such as hemodynamic variations, analgesia & sedation, confirmation of the correct position of your endotracheal tube, and setting up the ventilator based on your patients physiology. Too often physicians pay little or no attention to how our amazing respiratory therapists set up the ventilator. Respiratory therapists have expertise in setting up, weaning and trouble-shooting the ventilator, but clinicians need to communicate important clinical physiologic information and their goals for their patient on mechanical ventilation. If you don’t feel comfortable setting up the ventilator at this point you at the very least need to communicate with your respiratory therapist when the ventilator is being set up. Read more →
