Progression/Outcome

Twitter: CV kills via cardiac failure, not pulmonary

Seattle has ventilators but is out of ICU beds. Due to a lack of machines, Seattle is restricting ECMO machines to people <40 yo and < 25 BMI. Most people are dying of heart, not lung, issues

Twitter: Seattle ICU Dr describes conditions in Seattle hospital

Entire ICU taken up by CV patients, CDC is weakening quarantine on medics, they are out of masks in part because people are stealing from them
