#ARDS is an important priority in our ICUs at the moment. Our @CMAJ review looks at diagnosis, and provides a guideline-based approach to management, along with a discussion on #COVID19 ARDS.
A great primer for those new to ARDS!

Admission respiratory status predicts mortality in COVID-19 – hypoxemic patients (oxygen saturation less than 92%) had a 1.8- to 4.0-fold increased mortality risk; those with respiratory rates over 22 breaths per minute were at 1.9- to 3.2-fold elevated mortality risk.

2 signs easily measured at home can indicate increased Covid mortality risk—respiration rate & blood-oxygen saturation. Both are distinctly predictive of higher mortality. Anyone receiving a positive Covid test can easily monitor for these signs at home https://t.co/8n7oc0d4E4 pic.twitter.com/02ysVaElsL
