-                   No highly elaborate care.

-                  No constant monitoring or support of vital functions required.

○                 Exception:

▪                  Oxygenotherapy < 10 L/min to reach a minimal SaO2 > 90%

Mainly were hospitalised in this category patients with pre-existing conditions, that could predispose to an imminent worsening, e.g.,

-                   Moderate infect burden;

-                   Central PE;

-                   Age > 60 years;

Intermediate

Care

Unit

Severe Ill

o                   SaO2 < 90% under oxygenotherapy < 10 L/min.

o                   Tachypnoea > 30/min,

-                   Equipment-based monitoring required,

-                   Organ support but no organ replacement [14,15],
