Discover the benefits of Clarity Medtech HFCWO PneuVest Series technology
Severe lung congestion causing respiratory failure is likely to be one of the major causes of death in COVID-19 patients. It is important to remove mucus before beginning ventilation treatment. The PneuVest series high frequency chest wall oscillation (HFCWO) airway clearance system can improve the COVID recovery rate and reduce the mortality rate.

Why muscus removal matters
Severe lung congestion causing respiratory failure is likely to be one of the major causes of death in COVID-19 patients. It is important to remove mucus before beginning ventilation treatment. The PneuVest series high frequency chest wall oscillation (HFCWO) airway clearance system can improve the COVID recovery rate and reduce the mortality rate.
Â
Autopsies prove that severe mucus blockage in the lungs causing respiratory failure is likely to be one of the major causes of death in COVID-19 patients.
A leading forensic scientist urged “effective removal of mucus before use of ventilators…Ventilation is useless if mucus is not removed in advance” when treating COVID-19 patients.
The latest version of Guidelines for Diagnosis and Treatment of COVID-19 issued by the Chinese National Health Commission emphasises the importance of mucus removal.The latest version of Guidelines for Rehabilitation of COVID-19 Patients issued by the Chinese Medical Association Respiratory Committee recommended HFCWO specifically.
