At Home

Infants who have experienced an episode of prolonged sleep apnea associated with cyanosis, pallor, and limpness requiring vigorous stimulation or mouth-to-mouth resuscitation to restore breathing, are at risk of experiencing a recurrence that may result in death1.2. The American Academy of Pediatrics has recommended that such infants be treated by 24-hour surveillance either in the home or in the hospital. Electronic monitoring devices "may be useful adjuncts" to such surveillance.3 Since 1973, we have monitored 270 infants at home with apnea or cardiac monitors. A major problem with monitoring infants at home has been false alarms, such as alarms for apnea when the infant is breathing, on heart rate or apnea alarms due to a loose electrode.

Background. We determined the extent to which heart rate variability (HRV) responses to daily physical activity differ between subjects with and without chronic neck pain.Method. Twenty-nine subjects (13 women) with chronic neck pain and 27 age- and gender-matched healthy controls participated. Physical activity (accelerometry), HRV (heart rate monitor), and spatial location (Global Positioning System (GPS)) were recorded for 74 hours. GPS data were combined with a diary to identify periods of work and of leisure at home and elsewhere. Time- and frequency-domain HRV indices were calculated and stratified by period and activity type (lying/sitting, standing, or walking). ANCOVAs with multiple adjustments were used to disclose possible group differences in HRV.Results. The pain group showed a reduced HRV response to physical activity compared with controls (p=.001), according to the sympathetic-baroreceptor HRV index (LF/HF, ratio between low- and high-frequency power), even after adjustment for leisure time physical activity, work stress, sleep quality, mental health, and aerobic capacity (p=.02). The parasympathetic response to physical activity did not differ between groups.Conclusions. Relying on long-term monitoring of physical behavior and heart rate variability, we found an aberrant sympathetic-baroreceptor response to daily physical activity among subjects with chronic neck pain.

Heart rate is an important idicator of human physiology,it has great significance for human health in the long-term monitoring process.This research is based on Photo Plethysmo Graphy (PPG) principle.First,get some video via webcam,and then extract the signal of Face PPG.We proposed an improved ICA agortihm,because of the heart rate signal is a non-stationary and nonlinear signal,then,HHT-domain analysis of Face PPG signal.Finally,we succeeed in measuring of the heart-rate.The experimental results show that,using the improved ICA algortihm ,it is not only reduce the iteration ,but also has better measurement.

The principle of the static charge-sensitive-bed (SCSB) method is described. The method is simple and inexpensive. From the SCSB recording the ballistocardiogram (BCG) and respiratory movement can be simultaneously recorded by selective filtering of the original signal. The SCSB recording thus enables continuous long-term monitoring of the BCG, heart rate, respiratory rate, respiratory amplitude, and body movements. There are no electrodes or cables connected to the subject. The SCSB-BCG signal was studied by comparing the SCSB method with the conventional ultralow-frequency (ULF) acceleration BCG. The wave forms at rest and the amplitude responses to physical exercise were studied by both methods. Multiple recordings of the BCG, heart rate, respiratory movement, respiratory rate, and body movements after exercise and during sleep using the SCSB method are presented. The SCSB method opens new approaches to long-term studies of the regulation of myocardial performance, heart rate, and respiration. Applications of the SCSB method for clinical sleep studies, patient monitoring and cardiovascular screening examinations are discussed.

Test Result

For the issues of expensive price, cumbersome operations and bad portability, we designed a wireless, wearable and multi-parameter exercise physiological monitoring system with low mental loads. This system could perform the real-time, continuous and long-term monitoring for the parameters of ECG, respiration, body temperature and body movement of the person under monitoring in the motion state to realize wireless transmission of data. The test result showed that the operation of system is stable, safe and reliable to monitor the physiological status of the testee on a precise, real-time and ongoing basis.
