Abstract

Pernapasan merupakan salah satu tanda vital yang harus dipantau pada seorang pasien selain denyut nadi, detak jantung, suhu tubuh, dan tekanan darah, karena dapat mengindikasikan adanya suatu kelainan pada tubuh pasien. Dalam penelitian ini telah dilakukan rancang bangun sistem monitoring pernapasan berbasis serat optik berstruktur singlemode-multimodesinglemode (SMS) dengan jenis serat optik multimode coreless step index sepanjang 22,30 mm. Proses monitoring pernapasan terkait dengan fenomena perubahan suhu, tekanan, dan kelembaban pada udara pernapasan, dimana perubahan tersebut akan menyebabkan perubahan indeks bias kulit multimode coreless sehingga menyebabkan perubahan penjalaran cahaya yang terpandu didalam serat optik berstruktur SMS. Dari hasil eksperimen ditunjukkan sensor SMS mampu memantau pernapasan biasa, pernapasan cepat, dan pernapasan disertai batuk. Adapun kelembaban merupakan faktor dominan yang mempengaruhi kinerja sensor, dengan sensitivitas sensor sebesar 0,044 dBm/%. ========== Respiration is one of the vital signs that have to be monitored in medical patients alongsides with pulse rate, heart rate, blood pressure, and temperature as it may indicate the presence of a anomaly on the patient's body. In this research, a respiratory monitoring system has been done using singlemodemultimode-singlemode (SMS) fiber optic sensor structure with multimode coreless step index optical fiber by length of 22.30 mm. The respiration monitoring system is based on the phenomenon of temperature, pressure, and humidity changes in the breathing air, where such changes will lead to changes in the refractive index of multimode coreless cladding and then causing changes in the propagation of the light guided in the optical fiber structured SMS. The experiment results showed that SMS sensor can be used for monitoring normal breathing, fast breathing, and cough. Furthermore humidity is the dominant factor that affecting the performance of the sensor with 0.044dBm/% sensitivity.
