--- "Unsuccessful treatment of VAP is associated with greater mortality. The relatively long length of stay among patients with COVID-19 is primarily due to prolonged respiratory failure, placing them at higher risk of VAP."

Yep, COVID-19 patients can have vary long respiratory failure episodes due to viral pneumonia. The longer you are on the vent the higher the chance of complications, same as any other condition that requires a ventilator. Note that only 190 of 585 patients in this study had COVID-19...the majority of them had some other condition requiring a ventilator to keep O2 levels up and got bad outcomes with “VAP” too.
