This episode talks about what it means to be low or high flow and how to ensure that a system is in fact, high flow. This includes calculating air entrainment ratios, total flow, and finding minimal flow to ensure you meet the patient's inspiratory demand. I also talk about when to use a high flow system over a low flow one. Find the Ultimate Oxygen Therapy Study Package on www.myvresp.com.
