Objective:To compare the impact of manual right arm blood pressure measurement with computer-controlled blood pressure meter (CCBPM) on the detection rate of hypertension among elderly individuals.Method:This was a cross-sectional study. Elderly residents undergoing routine health check-up in a village in Jiangxi Province from April to June 2024 were enrolled. Manual blood pressure measurements were performed on the right arm using an electronic sphygmomanometer, while standardized dual-arm synchronized blood pressure assessments were conducted using the CCBPM. Blood pressure data were recorded from three sources: manual measurement on the right arm; the first CCBPM measurement on the arm with higher systolic blood pressure (CCBPM single); and the mean blood pressure of the arm with higher systolic blood pressure from two (if the difference between the first two measurements was less than 5 mmHg, 1 mmHg=0.133 kPa) or three (if the difference exceeded 5 mmHg) CCBPM measurements (CCBPM mean). Hypertension detection rates from these three datasets were compared. Subgroup analysis was performed according to age (60-74 years old as the elderly group,≥75 years old as the senior group) and gender. Intra-group correlation coefficient ( ICC) was analyzed to evaluate the consistency of blood pressure data of different blood pressure measurement methods, and Kappa value was analyzed to evaluate the consistency of hypertension classification determined by different blood pressure measurement methods. Results:A total of 1 498 participants were enrolled, aged (71.30±6.83) years old, including 678 males (45.26%). The blood pressure and heart rate measured by the artificial right arm blood pressure measurement were higher than those measured by CCBPM single (blood pressure: (140.09±17.19)/(82.40±10.93) mmHg vs. (135.31±18.98)/(81.23±10.51) mmHg; heart rate: (75.76±11.72) beats/min vs.(72.94±11.21) beats/min) and CCBPM mean (blood pressure: (140.09±17.19)/(82.40±10.93) mmHg vs. (134.64±18.39)/(80.28±9.78) mmHg; heart rate: (75.76±11.72) beats/min vs. (72.87±10.70) beats/min, all P<0.05). The detection rate of hypertension determined by CCBPM mean was significantly lower than that of artificial right arm (40.25% (603/1 498) vs.54.34% (814/1 498)) and CCBPM single (40.25% (603/1 498) vs. 44.79% (671/1 498), all P<0.05). Subgroup analysis showed that that the detection rate of hypertension determined by CCBPM mean was lower than that measured by artificial right arm regardless of gender and age (all P<0.05). The consistency of blood pressure data between artificial right arm and the CCBPM mean was moderate (systolic blood pressure: ICC=0.70; diastolic blood pressure: ICC=0.62), with less consistent classification ( Kappa=0.37). The consistency of blood pressure data between CCBPM single and CCBPM mean is extremely high (systolic blood pressure: ICC=0.94; diastolic blood pressure: ICC=0.91), with highly consistent classification ( Kappa=0.74). Conclusions:Artificial right arm blood pressure measurement in physical examinations may overestimate the hypertension detection rate, and the standardized dual-arm synchronized blood pressure measurement using CCBPM can reduce irregular blood pressure measurement.

Objective:To investigate the correlation between age and tongue pressure in healthy individuals using a newly-developed tongue pressure measuring device.Methods:A total of 154 healthy volunteers aged 20 to 97 years, without noticeable swallowing difficulties, were selected and divided into seven age groups: 20-29 years ( n=24), 30-39 years ( n=22), 40-49 years ( n=20), 50-59 years ( n=24), 60-69 years ( n=22), 70-79 years ( n=22), and 80 years or more ( n=20). Their maximum, minimum, average and initial pressures, work done, and coefficients of variation were measured using the newly designed tongue pressure measuring device in its intermittent and continuous measurement modes. The tongue pressures were correlated with age and gender. Results:The pressure data obtained using the new device were completely consistent with those from a manometer ( R=1). In the intermittent measurement mode, the readings showed that the maximum, minimum and average tongue pressures decreased significantly with age. In the continuous measurement mode, the initial tongue pressure, average pressure and work done also decreased significantly with age, while the coefficient of variation generally increased with age. There was a negative correlation between age and average tongue pressure ( R2=0.4). The relationship could be expressed as y=-0.8595x+ 103.3 (where x is age, and y is tongue pressure). However, no significant correlation was found between gender and tongue pressure. Conclusions:Tongue pressure and its stability are negatively correlated with age in healthy individuals without swallowing dysfunction, showing no significant correlation with gender.

Patients in the intensive care unit (ICU) often need to have various catheters placed on their bodies due to their severe condition. In order to prevent the occurrence of unplanned extubation, patients' hands should be restrained appropriately. The current restraint gloves used in clinical practice have problems such as improper restraint, easy falling off of oxygen saturation monitoring probes, and pressure injury of hands. Therefore, department of critical care medicine, Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine designed a wrist restraint glove suitable for restless patients, and obtained the national utility model patent (ZL 2020 2 1612453.7). The device is composed of restraint gloves and restraint rings, which can not only restrain patients, but also continuously monitor the changes of blood oxygen saturation in patients with restfulness. This device is convenient to use, low cost, comfortable to wear, and can prevent the occurrence of device-related pressure injuries, which is suitable for clinical application.
