Abstract Background Pressure Garment Treatment (PGT) is currently recognized as an effective method to prevent scar formation or treat scar hyperplasia. Research on PGT remains controversial. These controversies indicate that PGT lacks reliable evidence of evidence-based medicine. Different studies on PGT need to be conducted under the same ‘gold standard’ so that different studies can be compared. We consider this ‘gold standard’ to be that the pressure remains stable within a confidence interval during treatment. Methods We calibrated and verified the reference value of the sensor using a cuff of sphygmanometer.A pressure adjustable pressure system was obtained by installing a soft tissue expander on the pressure garment.Local pressure was adjusted by charging and releasing air.Subsequently, the flexible pressure sensor was placed on the upper arm of the healthy volunteers. We validated the compression system on healthy volunteers' forearms and AO standard prostheses (forearms). Results Reference value of the sensor was calibrated on No.1 volunteer. Measuring repeated on No.2 and No. 3. The measurement was very reproducible. The test results in the experimental group showed that the local pressure gradually increased with the increase of the inflation of the airbag. However, the pressure at the opposite position of the forearm changed little. Conclusions Real-time pressure monitoring and pressure adjustment enable the pressure to be maintained at a certain value. Our study provides a new idea for the production of elastic clothing with the function of pressure measurement and pressure regulation, which may promote the accuracy and reliability of PGT.

The purpose of this study was to evaluate outdoor PM2.5 infiltration into multifamily homes according to the building characteristics using regression models. Field test results from 23 multifamily homes were analyzed to investigate the infiltration factor and building characteristics including floor area, volume, outer surface area, building age, and airtightness. Correlation and regression analysis were then conducted to identify the building factor that is most strongly associated with the infiltration of outdoor PM2.5. The field tests revealed that the average PM2.5 infiltration factor was 0.71 (±0.19). The correlation analysis of the building characteristics and PM2.5 infiltration factor revealed that building airtightness metrics (ACH50, ELA/FA, and NL) had a statistically significant (p < 0.05) positive correlation (r = 0.70, 0.69, and 0.68, respectively) with the infiltration factor. Following the correlation analysis, a regression model for predicting PM2.5 infiltration based on the ACH50 airtightness index was proposed. The study confirmed that the outdoor-origin PM2.5 concentration in highly leaky units could be up to 1.59 times higher than that in airtight units.
