Killer COVID19 Masks? The Truth About Trapped Carbon Dioxide

20200622· The Truth About Trapped Carbon Dioxide. June 22, 2020. COVID19 can kill. Now, according to a misguided Internetfueled theory, masks can kill, too. All it takes is a maskwearer who inhales freshly exhaled carbon dioxide repeatedly until dizzy, unconscious or dead. That, no doubt, would be a shocking development. In the real world, the average mask user without preexisting respiratory …

HVAC Safety Tips: Don’t Let Carbon Monoxide Sneak Up On You

20200213· For one thing, low levels of the poisonous gas don’t always cause a CO sensor to go off, especially the kind that are installed in the ceiling and hardwired to your electrical system. They are often programmed only to go off if carbon monoxide levels are dangerous enough to cause death. However, according to the US Center for Disease Control (CDC), prolonged exposure to low levels of carbon ...

COVID19: How to Monitor Your Oxygen Level

COVID19 can cause an infection in your lungs, which can lower the oxygen level in your blood. When your oxygen level is low, you may feel tired or have shortness AM of breath, but you may not feel different at all. This can be dangerous. You should keep track of your oxygen level using a fingertip oxygen meter until you are feeling better. If your oxygen level drops, you should get medical ...

Identifying poorly ventilated areas and using CO2 monitors

People exhale carbon dioxide (CO2) when they breathe out. If there is a buildup of CO2 in an area it can indicate that ventilation needs improving. Although CO2 levels are not a direct measure of possible exposure to COVID19, checking levels using a monitor can help you identify poorly ventilated areas. Types of CO2 monitor to use. There are many different types of CO2 monitors available ...

Ventilation in the context of COVID19

COVID19 is thought to be primarily transmitted via large respiratory droplets, however, an increasing number of outbreak reports implicate the role of aerosols in COVID19 outbreaks. Aerosols consist of small droplets and droplet nuclei which remain in the air for longer than large droplets [5,6]. Studies indicate that SARSCoV2 particles can remain infectious on various materials , as well ...
