Abstract
To Comparatively Evaluate Oxygen Saturation Level Among Dental Health Professionals Using 3 Different Types of Masks -N95, KN95 And Surgical Three-Layered Mask
Highlights
Settings and Design: Double blinded Randomized Clinical Trial Methods & Materials: Total 90 Dental health professionals were randomly assigned into three groups; Group A-N 95 mask (3M), Group B-KN 95 mask (3M) and Group C- Surgical three-layered mask (3 ply Surgical mask)
If we look at the individual groups it shows statistically significant difference in Group B (KN95) mask at pre and post 1 hour interval (P
The present study shows that oxygen saturation level in dental health professional wearing N-95 mask before was mean range of 10.86 and after one hour was 12.14 that did not elicit a statistically significant difference (P value-0.84).(Table-2)
Summary
Each system and structure in the body requires oxygen for living. Cells begin to malfunction, eventually die leading to organ failure [1]. Standard oxygen saturation values are between 95 and 100 percent. Oxygen saturation levels below 90 percent are considered abnormally low and can be a clinical emergency [2]. The device used to measure the Oxygen saturation level is called as ‘Pulse Oximeter’. This device can be attached to a finger, a wrist, a foot, or any other area where the device can detect blood supply [3-5]
