Assessment of Chest Drains

exp date isn't null, but text field is


Chest tubes and drain systems can be confusing. This ICU #OnePager shows you how they work and demonstrates a 5-step tool for assessing positioning, drainage, tidaling, air leak, and suction. Also demonstrates how to build a three bottle drainage system in case you find yourself managing pnuemothoraces on a desert island (or an airplane).
