Development of Vital Signal Monitoring System Based on Accelerometer / 中国医疗器械杂志

OBJECTIVE@#Reduce the number of false alarms and measurement time caused by movement interference by the sync waveform of the movement.@*METHODS@#Vital signal monitoring system based on motion sensor was developed, which collected and processed the vital signals continuously, optimized the features and results of vital signals and transmitted the vital signal results and alarms to the interface.@*RESULTS@#The system was tested in many departments, such as digestive department, cardiology department, internal medicine department, hepatobiliary surgery department and emergency department, and the total collection time was 1 940 h. The number of false electrocardiograph (ECG) alarms decreased by 82.8%, and the proportion of correct alarms increased by 28%. The average measurement time of non-invasive blood pressure (NIBP) decreased by 16.1 s. The total number of false respiratory rate measurement decreased by 71.9%.@*CONCLUSIONS@#False alarms and measurement failures can be avoided by the vital signal monitoring system based on accelerometer to reduce the alarm fatigue in clinic.

Effects of rehabilitation exercises on quality of life of patients undergoing revascularization for coronary heart disease / 中华健康管理学杂志

ObjectiveTo investigate the effects of treadmill testing guided-rehabilitation exercises upon quality of life (QOL) of patients who underwent revascularization for coronary heart disease (CHD).Methods All the participants received routine therapy and rehabilitation for 6 weeks.A 36-item short-form (SF-36) was used to assess QOL of the patients.Results Injured functioning of patients who received revascularization for CHD were physiological function ( 37.86 ),social function ( 43.67 ),vitality (45.58),physical performance ( 65.45 ),mental health ( 68.73 ),role emotion ( 71.30 ),physical pain ( 79.52 ),and general health ( 86.75 ).After intervention,physiology function ( 37.86 ± 8.49 vs 62.13 ± 10.53 ),social function (43.67 ±26.23 vs 56.98 ± 18.89),vitality (45.58 ±27.01 vs 77.42 ±23.48),and physical pain (79.52 ±9.05 vs 87.32 ± 13.14) were significantly improved.Conclusion Rehabilitation exercises and behavioral psychological treatment may be beneficial to improve QOL of patients undergoing revascularization for CHD.
