Impact of the modification of a cleaning and disinfection method of mechanical ventilators of COVID-19 patients and ventilator-associated pneumonia: one year of experience

The control of health care-associated infections (HAI) in COVID-19 patients is one of the main challenges of current critical medicine, since its control directly impacts the recovery of the patient1. HAI are adverse events, and to our knowledge, no health institution in the whole world is free of them, and in the current SARS-CoV-2 pandemic they are of greater attention2. The most frequent HAI in the adult intensive care unit (AICU) is the ventilator-associated pneumonia (VAP) caused by bacteria from the ESKAPE group, where mechanical ventilators play an important role3,4.
