This study aimed to determine whether wearing N95 masks for 4 h significantly affected physiological indicators in obese operating room staff compared to surgical masks (SMs). In this randomized crossover trial, the physiological impacts of wearing SMs and N95 masks for 4 h was analysed among 20 obese operating room staff. The data were connected to a nasal sampling tube using the Capnostream 20p monitor. The primary outcome was the change in venous carbon dioxide partial pressure (PvCO) levels at 4-hour intervention. Secondary outcomes included venous oxygen pressure (PvO), bicarbonate (HCO), pH levels, end-tidal carbon dioxide partial pressure (PetCO), peripheral oxygen saturation (SpO), respiratory rate (RR), pulse rate (PR) and blood pressure after mask intervention. Dyspnoea, palpitations, headache were assessed with the visual analogue scale (VAS) score. N95 masks had a statistically significant rather than clinically significant impact on PvCO (mean [95% CI], 1.4 [0.8, 1.9], P < 0.001) and RR (0.6 [0.1, 1.1)], P = 0.023) changes compared with SM. The three subjective VAS scores of the N95 group showed significantly increased than SM group after 2 h. In conclusion, obese operating room staff continuously wearing SM or N95 masks 4 h showed almost no difference in physiological impacts. Trial registration NCT05950256, 18/07/2023.

Background: The global COVID-19 pandemic has necessitated the widespread use of N95 masks, yet their impact on children with chronic conditions like type 1 diabetes (T1DM) remains underexplored.
Objective: This study investigates the effects of N95 mask usage on clinical outcomes in children with T1DM.
Methods: This study enrolled 34 children aged 10-18 with T1DM.
The role of masks and respirators in preventing respiratory infections in healthcare and community settings.

The covid-19 pandemic saw frequent changes and conflicts in mask policies and politicization of masks. On reviewing the evidence, including studies published after the pandemic, the data suggest respirators are more effective than masks in healthcare, but must be continuously worn to be protective. Healthcare and aged care settings amplify outbreaks, so protection of patients and staff is paramount.

Historically, the use of a face mask has been associated with personal protection during epidemics. However, the type of mask used and the way it is used can affect the level of protection it provides. To analyze the practices of using face masks in the population in the Northeast of Brazil, a cross-sectional study was carried out, from December 2021 to February 2022, through interviews with 308 people at bus stops (simple random sample).

Experts suggest wearing a face mask during a radiation emergency if it is impossible to get inside immediately and high-level protective respirators are unavailable. This study quantitatively investigated seven face mask materials' ability to block radioactive alpha and beta radiation. Rayon fiber, pure cotton, paper fiber, polyester fiber, nonwoven fiber, advanced nonwoven fiber, and N95 were examined.
