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 →

Mechanical Ventilation is a modality commonly used in the critically ill, but many providers, may not have a strong understanding of the basics. Emergency Medicine and Critical Care Physicians need to have a firm grasp of the basic concepts of mechanical ventilation because without it, we can do serious harm to our patients. Airway management is not complete once the endotracheal tube is placed through the cords, and the proper selection of both the ventilator mode and initial settings is essential to ensure your patient has the best possible outcomes. You should not simply rely on the respiratory therapist to know your patients physiology. Clear communication with your therapist about the patient’s physiology and initial ventilator setting is crucial. Read more →
