User reviews

Extremely helpful and educational

I recently downloaded this app as a medical student applying to anesthesiology residency in his year to familiarize myself with the ventilator as I go through clinical rotations. And I have to say this is one of the most comprehensive sources I’ve found about ventilators. And it’s not just about 1 type of ventilator. There is so much information about the different kinds of elevators and discussion of the physiology. Can’t recommend enough to those in anesthesiology, critical care, and high acuity settings. Dr. Rishi Kumar is clearly an amazing educator! He has several other apps he developed as well that are worth checking out!
