This study was conducted to examine the effects of different masks used by pregnant women on vital signs and non stress test (NST) during the COVID-19. This study was conducted as a single-blind randomized controlled trial. Healthy pregnant women aged 19 years and older, who were followed up on an outpatient basis, and who were in the 37-40th week of pregnancy, were included in the study. The study consisted of a single surgical mask group (n=30), double surgical mask group (n=30), and N95 mask group (n=31). Masks were given to the resting pregnant women 30 minutes before the NST, and they were provided to wear masks. After 30 minutes, the vital signs of the pregnant women were measured just before and after the NST, and the images of the NST traces were taken.
