The pandemic of COVID-19 is omnipresent. Today is the 28 th March 2020. You are having your night shift at the intermediate care department of infectious diseases in the regional hospital. Today you are writing the 2nd admission report of a patient with a confirmed COVID-19 infection. Suddenly, you hear a saturation alarm from the next patient box. How do you act?

A history and more detailed information about the patient can be found at the bottom of the algorithm in the "examination".
Help
I activate the local CPR protocol in the COVID-19 positive patient. Early call for the resuscitation team is included in this protocol.
I put on the protective gown, gloves, eye protection and surgical face mask and as quickly as possible check the cardiac arrest and begin the CPR, if indicated.
I check the plan of treatment. In case of no withdrawal of the care, I activate the local CPR protocol in the COVID-19 positive patient. Early call for the resuscitation team is included in this protocol.
I check the plan of treatment and call for the resuscitation team. I do not approach the patient before their arrival.
