    Author(s): Sharafaldeen Bin Nafisah*, Abdulqader Susi, Ebrahim Alsaif, Mazen Alqasmi and Bandr Mzahim

    Background: The use of N95 masks by Healthcare Providers (HCPs) has increased throughout the COVID-19 pandemic. Thus, the question arises as to whether wearing this type of mask influences the concentration of carbon dioxide (CO2) and oxygen (O2) in the blood. Methods: We analyzed CO2 and O2 concentrations, measured in millimeter mercury. Our inclusion criteria were as follows: wearing N95 mask continuously for four hours, and working in an acute care setting that mandates continuous physical activity. Excluded were those who interrupted the four hours and those who voluntarily quit the study. We measured the partial pressure of CO2 and O2 from venous blood samples taken before and after wearing the N95 mask. Results: The total number of participants i.. Read More»
