Wireless tele-auscultation for phonocardiograph signal recording through Zigbee networks
Conference Publication ResearchOnline@JCUAbstract
Some factors that arise from difficulties in identifying in detail the cardiac signal can lead to heart disease diagnosis process becomes biased. For example, diagnosis process is strongly influenced by the subjectivity of the doctor, this is primarily due to exposure of patient chest area during the process of measurement. One solution to cope with this problem can be done by allocating doctors and patients in separate rooms. Hence, this was the main motivation of our work. In this paper, we examine the use of a wireless tele-auscultation system for transmitting and recording phonocardiograph signal. The data is transmitted through the Zigbee-like (called the Xbee) networks in local area networks. Based on the study, it is shown that the Type A loss can be omitted without affecting the validity of the received signal as long as time length of measurement is longer than the transmission delay. In terms of the Type B loss, it can be argued that the transmission process is considered as valid, i.e. even though there are loss packets, the number of the loss packets is not significant. In addition to that, it can be observed that variation of the sampling period and the serial interface data rate do not contribute well to the improvement of the throughput the streaming heart sound signal transmission. The throughput of the system is probably influenced by the surrounding environment and hardware or memory capability of the Xbee.
