ABSTRAKPada studi ini dilakukan rancang bangun sistem perekam detak jantung portabel berbasis pulse heart rate sensor. Studi ini bertujuan untuk mengetahui keakuratan pulse heart rate sensor dalam mendeteksi detak jantung pada jari tangan, dimana tahap selanjutnya sistem ini akan digunakan untuk merekam detak jantung pasien seharian dalam kondisi beraktivitas. Sistem ini dirancang menggunakan modul pulse heart rate sensor yang dihubungkan dengan mikrokontroller Arduino Nano. Data detak jantung direkam pada modul SD Card. Hasil pengukuran sistem ini dibandingkan dengan hasil pengukuran alat Oxymeter. Pengujian dilakukan dengan mengukur detak jantung bagian jari tengah dengan alat Oxymeter dan bagian jari telunjuk dengan sistem ini. Pengujian dilakukan masing-masing satu kali pada 2 jari tangan kanan dan tangan kiri dari 30 orang naracoba dengan rentang usia 18-23 tahun. Hasil pengujian menunjukkan rata-rata error akurasi sistem ini adalah 2 bpm terhadap Oxymeter dengan selisih terbesar 5 bpm. Kata kunci: detak jantung, jari tangan, Oxymeter, SD Card, sensor pulse heartrate. ABSTRACTIn this study, we implemented a portable pulse heart rate sensor based heart beat recording system. The goal of this study is to evaluate an accuracy of the sensor for detecting the heart beat on both a right finger and a left finger in order to implement an ambulatory heart beat recording system. The pulse heart rate sensor was connected to an Arduino Nano contoller module to calculate the heart beat. The heart beat was then recorded in a SD Card module. The system’s results were compared to an oxymeter. Thirty healthy young adult volunteers were involved in this study by measuring the heart beat on a middle finger with Oxymeter and on an index finger with our system. The measurement was tested on both hands’s fingers. The results showed that an accuracy of the system is 2 bpm relative to the Oxymeter’s with the biggest difference of 5 bpm.Keywords: fingers, heart rate, Oxymeter, pulse heart rate sensor, SD Card

The purpose of this study was to assess the effectiveness of nasopalatine nerve block for anesthesia of maxillary central incisors after failure of the anterior superior alveolar nerve (ASAN) block technique. Secondarily, the possible innervation of the maxillary central incisors by the nasopalatine nerve was also investigated. Twenty-seven healthy, young adult volunteers (age: 17-26 years; gender: 9 males and 18 females) were enrolled in this study. All participants were undergraduate dental students of the University of Vale do Rio Verde de Três Corações. The volunteers had the anterior superior alveolar nerves anesthetized and a thermal sensitivity test (cold) was performed on the maxillary central incisors. The volunteers that responded positively to cold stimulus received a nasopalatine nerve block and the thermal sensitivity test was repeated. All participants were anesthetized by a single operator. Three patients presented sensitivity after both types of bilateral blocks and were excluded from the percentage calculations. In the remaining 24 patients, 16 had their maxillary central incisors anesthetized by the anterior superior alveolar block and 8 remained with sensitivity after the ASAN block. All these 8 patients had their maxillary central incisors successfully anesthetized by the nasopalatine block. In this study, 33.3% of the subjects had the innervation of one or both maxillary central incisors derived from the nasopalatine nerve, whilst most subjects (66.7%) had such teeth innervated by the anterior superior alveolar nerve. The nasopalatine nerve block was effective in anesthetizing the maxillary central incisors when the anterior superior alveolar nerve block failed.

In recent times most of the automotive vehicle accidents are increased day by day in India. Recent causes of the accident shows that more than 20% of accidents are caused due to health issues which occur to drivers while driving the vehicle. In the proposed project we had been monitoring the status of health condition of the driver by using sensors such as pulse rate sensor and temperature sensor. The heart beat rate falls below the lower limit and above the higher limit to the driver. The driver can be prevented from driving the vehicle when he is in extreme emotion such as heart attack, arrhythmias, heart stiffening or weakening, cardiomyopathy, stress, anxiety, depression etc. The speed of the vehicle is measured by speed sensor in the vehicle. The ultrasonic sensor which is used to sense the object placed in the front of the vehicle. The result is to create a system capable of contributing to the reduction of collisions. The driver who suddenly suffers from health issue especially heart attack while driving the vehicle cannot handle the vehicle because during heartache the movement of hands is difficult to control the vehicle which leads to accidents. The heart rate sensor placed in seatbelt of the driver and heat sensor in the driver seat. The sensors collect the data and send it to the control unit which interprets the data with the standard value and if some values are unusual may be in heart rate, blood pressure. The control unit sends out a warning signal to the driver and if the driver doesn’t show any reaction within the set time the braking system is actuated.
