A specific type of nasal oxygen therapy for Covid patients does not cause a higher risk of virus infection for health care workers. In an article in Respiratory Care, researchers from the group of Daniel Bonn (UvA-IoP) and from the Amsterdam UMC conclude that this therapy does not increase the risk of aerosol formation. The result may help in lessening the pressure on ICUs.

According to the researchers, which include UvA physicists Daniell Bonn and Stefan Kooij, the result takes away the worries about the use of high flow nasal oxygen (HFNO). This is a special technique used to administer a high flow of heated and moistened oxygen to the (Covid) patient through a nasal cannula.
Hand-Held Particle Detector Measures Aerosol Concentrations in Public Spaces
Written by AZoSensorsDec 23 2020
Because of the role they play in coronavirus transmission, understanding aerosol concentrations and persistence in public spaces can help determine infection risks. However, measuring these concentrations is difficult, requiring specialized personnel and equipment.
That is, until now.
Researchers from the Cardiology Centers of the Netherlands and the University of Amsterdam demonstrate that a commercial hand-held particle counter can be used for this purpose and help determine the impacts of risk-reducing measures, like ventilation improvements.
They describe the quick and easy, portable process in the journal
Physics of Fluids, from AIP Publishing.
