Are you ready to learn about Airway Management? If so, you’ve come to the right place, because that is what this study guide is all about.
As a Respiratory Therapist, making sure a patient is ventilating properly is one of our most important duties. And in order to receive adequate ventilation, the patient must have a patent airway.
That is why this section is so important for Respiratory Therapy Students. It’s critical that you know how to manage the patient’s airway properly — not only for your classes in school but also the board exams as well.
And, not to mention, you’ll need to especially understand this information in the real world once you become a Respiratory Care Practitioner and start seeing patients on your own. So if you’re ready to get started, let’s go ahead and dive right in.
One more note: This information correlates well with Egan’s Chapter 36 from the 11th Edition. So you can use this study guide to help prepare for your exams.

So there you have it! That wraps up our study guide on Airway Management. I hope that this information and these practice questions were helpful to you.
As I said before, this information is extremely important no matter where you are along your journey to becoming a Respiratory Therapist. Still in school, preparing for boards — it doesn’t matter. You need to have a full understanding of airway management.
Hopefully this guide can help you along the way. Thank you so much for reading and as always, breathe easy my friend.
