Has the time come again for Negative-pressure ventilation, to assist COVIT19 patients in a more humane way during a lung failure.

Please read the attached article and form your opinion, thank you.

Negative-pressure ventilation: is there still a role?

Negative pressure may make the virus concentrate on the top floor, unless all rooms are ducted. But i agree with the idea, this would undoubtably help nhs workers.

Something like this?

Well, if we have some, it's worth thinking about

Thank you for your contributions.

We all have had an experience of a heavy cold, with blocked nose, high temperature and a chesty cough.  All flue like symtoms which are similar in COVIT19, only much more enhanced.

Two types of Ventilators are available, the current " Positive Pressure" ventilator and the  most forgotten "Negative pressure" regulator, which came to fame shortly after WWII during  the Polio outbrake. While most of us are familiar with the" Positive pressure ventilator", some physicians have called for a Positive pressure ventilator for a number of reasons. Be it the low cost, or the quick application in the field, any medically trained person can install this equipment from any 12 volt car battery.

Positive Pressure Ventilator:
Technology: High Tec, requires highly trained medical staff for set-up and super vision
Physiological experience : is often accompanied by physical sensations such as heart palpitations, fear, chest pain, or headache, overpressure sensation during cough.
Other experiences:  Limited movement possibility

Negative Pressure Ventilator: (Concept idea)
Technology: Low Tec, may installed by any medically trained person
Physilogical experience: not yet investigated
Other experiences: Greater comfort during the treatment,ability to freely move and to carry out all body functions, eat and drink whilst being disconnected from the support system for 30 minutes or more.

I invisage many compact future application for Negative Pressure Ventilators, outside the field of medicine.

Sorry, gor the wrong end of the stick, didnt read the linked paper, thought you where going on about something like this, but a bit more vigorous

Thank you for your kind link.

As it so happens, your link of spam.co.uk on negative pressure ventilation was so brilliantly timed, as future building regulations will probably have to take into account air-born viral infections of private and commercial dwellings. This would require the installation of inlet and outlet air filters, which meet the minimum requirements of the current N95 air-filter standard.

This rings a few bells from my COSHH training many years ago.  Thanks again.

Im pretty sure that the hospital ventilation is not adequate for viruses, the regulations concerning air change per hour/day for moisture  and  health levels in your average build are not adequate for a hospital with wards full of virus patients. Problem there is the heat exchange of air, most hospitals i should doublt a great deal have heat recovery and the cost of changing all of air each minute would very  very  expensive.
