ICU Learning

Sami Safadi, M.D.

The goal of building this site is to provide high-quality learning modules to help learners understand pertinent physiological processes in critically-ill patients.

Please use a modern browser such as Google Chrome, Mozilla Firefox, Apple Safari, or Microsoft Edge. The modules work on mobile devices as well, however, some modules don't show very nicely on smaller screens.

Mechanical Ventilation


Positive-pressure mechanical ventilation is a life-saving intervention commonly performed in the intensive care units for patients with respiratory failure. Proficiency in setting up, and monitoring the ventilator is an essential skill in modern intensive care practice.

The modules provided simulate interactions between a patient and a ventilator. The modules can be accessed in a web browser, or by downloading the app (see the link buttons below) Different modes of mechanical ventilation are presented. Clinical scenarios can be simulated by changing the properties of the lungs, and the parameters of the ventilator.

To use the mechanical ventilation simulation modules, we require you to have an account with us. If you choose to create an account, you must provide a minimum amount of personal information (your name and either an email address or a phone number) associated with that account.

By registering with this website, or using the app you are provided free access to the ventilator simulaton modules. You also agree to allow use of your deidentified usage data of this website in manuscripts related to use of web-based learning in medical education. Please refer to the Terms and Conditions and Privacy Policy for details.

Video Tutorials

I started creating a series of videos to teach the basics of mechanical ventilation. You can access the videos on youtube by clicking THIS LINK.

Resucitation Ultrasound


resUs is an educational app developed for physicians using resuscitation point-of-care ultrasound to take care of critically-ill patients. It provides hemodynamic calculators and high-quality educational content (cardiac, vascular, visceral ultrasound) in one place.
