Effect and management of corona in different phenotypes.

L-Phenotype	H-Phenotype
Low elastance (HLC)	High elastance (LLC)
Low ventilation perfusion ratio	High shunt from right to left
The low weight of lung	The high weight of lung
Low recruitability	High recruitability
PaO2/FiO2 = 95 mmHg	PaO2/FiO2 = 84 mmHg
Non-intubated patients	Severe ARDS treated patients
-HFNC, CPAP, NIV	-PEEP is higher,
Intubated patients:	-Prone position lying
-Volumes greater than 6 mg/kg (up to 8−9 mg/kg) can be ventilated for hypercapnic patients	-Extracorporeal support
-PEEP reduced 8−10 cm H2O
-Prone positioning only as a rescue maneuver
