Abstract:
The coronavirus COVID-19 pandemic has highlighted the widespread necessity for
adequate personal protective equipment for healthcare providers, including during the
aerosol-generating procedure of tracheal intubation. Apart from the personal protection
equipment several other techniques and equipment have been reported to restrict the
exposure of healthcare workers to aerosols This work is devoted to the determination the
minimum ventilation requirements to reduce the transmission of the pathogen and the
realization of a variable speed ventilation box for procedures with a high risk of SARSCoV-
2 infection. This will ensure the patients isolation and accessibility of monitoring,
ventilation, treatment devices and convenience to perform the curative procedures on a
patient with COVID-19, reducing the risks of pathogens transmission from patients to
medical workers during aerosol-generating procedures, but also preventing patients
overinfection by re-inhalation of the agent. The protection box can be used by hospitals
that do not have rooms with specific conditions for performing aerosol-generating
procedures (rooms with possibility to generate negative pressure, rooms with a ventilation
rate of 160 l / s / patient or at least 12 environmental air changes per hour), and the
existing ventilation system does not provide the minimum requirements necessary to
prevent the infection among the medical staff.
