Throughout the pandemic, there has been considerable discussion about the possibility of running our of ventilators. One potential solution that was brought forward was putting multiple patients on a single ventilator. This is a lot harder than merely attaching a plastic splitter on a ventilator. In this episode, we explain safety and physiological considerations. Also, we briefly discuss specific patient care issues and ventilator settings if your circumstance requires you to adopt this approach.

Splitting a Ventilator: Multipatient Ventilation for COVID?

This week we have a brief conversation about prone mechanical ventilation for ARDS. Does it provide a benefit? When should we use it, and why does it work? I hope this is helpful as prone ventilation has been reported to provide benefit to patients with ARDS secondary to Coronavirus (COVID-19) infection.

Prone Ventilation for ARDS (COVID-19)

Today we discuss the approach to oxygenating and mechanically ventilating a patient suffering from ARDS. We will cover elements relevant and essential in the management of COVID patients and all others with ARDS.

ARDS and Mechanical Ventilation / COVID-19 Care

I'm back. I plan on providing you with some useful information when caring for patients infected with COVID-19 (Coronavirus). In this episode, I will provide you an overview of the current evidence and best practices with some explanation and commentary from the recent Surviving Sepsis COVID-19 guidance.
