| Abstract: | According to the estimates of life expectancy at birth provided by the World Health Organization (WHO) and The Census and Statistics Department Hong Kong (C&SD), the average life expectancy in Hong Kong and the rest of the world in 2021 will be 73 [1] years for females and 87.3 years for males. These figures are based on the population of Hong Kong in 2021. These statistics are from the World Health Organization as well as the Census and Statistics Department of Hong Kong, in that order. If these forecasts are accurate, the median age of a woman will have reached 93.1 years by the year 2066, while the median age of a man would have been 87.1 years at that time. [2] Vital signs are one of the most essential numbers that health care professionals use to examine and evaluate a patient's current health state. These signals include a patient's breathing rate – Respiratory Rate (RR), Blood Pressure (BP), Body Temperature (BT), and Pulse – Heart Rate (HR). This advance in preventative medical treatment is designed to accommodate a rise in the number of years, on average, that a person lives (HCP). Fiber optic sensors are one of the non-intrusive sensor technologies that can meet the requirements listed above. These characteristics make fiber optic sensors one of the senior technologies that can meet these requirements. As a result, it is now considered one of the most advanced devices that may assist HCP in collecting vital signs on a predetermined schedule or in real-time. This paper provides an explanation of the working principle as well as the classification of optical fiber sensors that measure vital indicators such as a person's heartbeat. In particular, the study concentrates on the process of counting heartbeats. Following the collection of the sign from the fiber sensor, the algorithm for heartbeat detection in ballistocardiogram (BCG) is applied to the raw data to transform it into a vital sign. This occurs after the sign has been acquired. The raw data is made up of the pulse signal that is sent over the fiber. Following the completion of the analysis, the patient may be informed of the results abregardinghe the myocardial contractility. The report, the carers, and the HCP will all make it simpler to avoid the anxiety that is associated with missing the important window of chance to save a life. Early intervention preventative activities are those that can be carried out immediately if it is recognized at an earlier stage. It will be much simpler to avoid the agony that comes with missing the brief but essential chance to save a life. |
