Summary : Smart mobile systems like micro-systems, smart textiles and implants and sensor-controlled medical devices, together with related networks and cloud services, are important enablers for telemedicine and pervasive health to become the next generation of health services. Social media and gamification have added further to pHealth as an ecosystem. This book presents the proceedings of pHealth 2019, the 16th in a series of international conferences on personalized health, held in Genoa, Italy, from 10 – 12 June 2019. The book includes 1 keynote, 2 of 4 invited talks, 36 oral presentations and 7 poster presentations from a total of 141 international authors. All submissions were critically reviewed by at least two independent experts and a member of the Scientific Program Committee. This process resulted in a full paper rejection rate of more than 30%. Besides wearable or implantable micro and nano technologies for personalized medicine, this volume addresses topics such as legal, ethical, social, and organizational requirements and impacts as well as necessary basic research for enabling future proof care paradigms. Such participatory, predictive, personalized, preventive, and effective care settings combine medical services and public health, prevention, social and elderly care, but also wellness and personal fitness. The multilateral benefits of pHealth technologies for all stakeholder communities offer enormous potential for the improvement of both care quality and industrial competitiveness, and also for the management of health care costs. Hence, the book will be of interest to all those involved in the provision of healthcare.

Summary : Purpose: The photoplethysmogram (PPG) recorded using finger pulse oximeter estimates the oxygen saturation. During out-of-hospital cardiac arrest (OHCA) the PPG waveform shows amplitude changes with chest compressions (CC. The aim of this study was to analyze the feasibility of using the finger PPG to provide feedback on CC rate during OHCA.Materials and methods: Records of 46 patients were included, comprising the PPG and compression depth signals extracted from Zoll E-Series defibrillator files. They were acquired by the DFW Center for Resuscitation Research (UTSW, Dallas) and the Emergency Medical Services agencies from the Resuscitation Outcomes Consortiumu2019s Portland site (OHSU). An automatic algorithm analyzed the PPG every 5s and detected useful PPG, presence of CCs and CC-rate. The compression depth signal (acquired by the CPR-pad-z) was used as the reference signal to simultaneously compute the rate and check for presence of CCs. The percentage of useful PPG, and sensitivity (SE)/positive predictive value (PPV) for detecting CCs were computed. The CC-rate error was assessed as mean(standard deviation) and 95% level of agreement (LOA, Bland-Altman). A feedback system on the CC-rate was implemented for the intervals where PPG was available, and evaluated in terms of SE, PPV and specificity (SP) to trigger alarms for CC-rates out of the range 90-120 CC/min.Results: A total of 420 min (9.1u00b17.6 min per episode) were processed. A total of 4971 segments were analyzed, 4319 including CCs with rate 116 (15) CC/min. The PPG signal was not available 17% of the time. The SE/PPV to detect CCs were 86.2/95.4%, and the CC-rate error 2.4 (6.3) CC/min (see figure). The SE/SP/PPV for the feedback system to trigger alarms were 83.6/92.4/85.3% respectively. Conclusions: When available, the finger PPG signal reliably gives feedback on CC rate.

Summary : Actively monitoring the heart rate and respiration rate is very essential as there exists a high correlation between these parameters and different cardiovascular events. Photoplethysmography (PPG) based heart rate monitoring is commonly employed in the smart watches and most of the industry products perform heart rate estimation only. However, it is difficult to keep accurate track of the heart rate or respiration rate by just using the PPG signal as it highly vulnerable to motion artifacts. This research presents a custom design for wearable wristband using PPG sensor which provides a single platform for heart rate, respiration rate along with activity monitoring and audio data recording. The research aims to solve the problems such as ambient light and variation in intensity of reflected light caused due to the hand as well as sensor motion by using multiple LEDs for measurement. Using adaptive filtering technique for motion artifact removal combined with peak verification step, the heart and respiration rate can be estimated within accepted error range even during different moderate physical activities.
