ICU Ventilation for COVID-19:
Assuming the virus is a low risk from an aerosolization point of view is it worth investigating the use of HEPA filters to purify the air in the room where we accommodate the COVID-19 patients? The same question can be asked with regards to the use of UV.
Is it not better to try and reduce the virus within the room, rather than filtering the air through a HEPA filter.
- The existing HVAC places our ICU is under positive pressure. For risk management when housing COVID patients, we wish to convert it to negative pressure. Any advice/ pointers?
- Please provide advice on recirculating air in an ICU, under COVID-19?
"It became clear to me that the spread of COVId-19 is directly connected to the spread of the active virus. Having been Hospital engineer at a 1200 bed local hospital, I am acutely aware that virus longevity depends on, i.a.:
- actual time that virus is inside its transmission-carrier fluid,
- actual temperature during its transmission, and
- concentration of virus in carrying fluid (as fluid may evaporate).
Could you consider providing a guideline on these time/temperature characteristics of the virus?
Only thereafter could architects, engineers etc. identify effective risk-reducing protocols. This could lead to more financially-justifiable 'anti-Corona' measures
Discussion
These questions are mostly unanswerable at the moment but I can . SARS-COV-2 is understood to
