Consultant Respiratory Physician Dr Ashish said: "When you use CPAP early in the admission it stops the patient getting worse, therefore avoiding invasive ventilation techniques. As CPAP is readily available and can be used in a ward setting, we have demonstrated that, when used early, it can be very effective way of treating severe COVID-19 pneumonia. ...snip... The researchers also found that the early use of CPAP potentially reduces lung damage during the worst of the COVID-19 infection and allows the patient to recover from the inflammatory effects. However, when used later, CPCP does not prevent lung damage thus leading to additional inflammation and a reduction in survival chances.
