Setting an adequate flow rate that meets a patient's peak inspiratory flow (PIF) is thus crucially important to achieve such effects. HFNC flow rate is typically set at 1 L/min/kg +1 as suggested by the manufacturer and increased to 2 L/min/kg according to the degree of respiratory distress. However, whether this empirical flow setting actually meets a patient's PIF has not yet been investigated. In this study, we implemented our previously described respiratory mechanics monitoring system (MAES) with a new spirometry function (NSS) that allows for a simultaneous visualization of the flow tracings of HFNC and the patient's spontaneous breathing. We tested the ability of NSS-MAES to determine the adequacy of empirically set flow rates of 1 L/min/kg +1 or 2 L/min/kg on 9 infants with respiratory distress receiving HFNC. HFNC flow rate was considered adequate if its tracing was just above the patient's respiratory flow. In patients in whom 1 L/kg/min +1 was inadequate, we used NSS-MAES to identify the adequate flow by raising the HFNC flow until it reached the patient's PIF (HFNC_NSS-MAES). We also investigated which flow rate was associated with the maximal decrease of respiratory effort, namely, Pressure Time Product (PTP) and Work of Breathing (WOB). We found that 1 L/min/kg +1, but not 2 L/min/kg was often unable to meet the patient's PIF. In these cases HFNC_NSS-MAES values were around 1.6 L/min/kg. Conversely, HFNC at 2 L/min/kg always exceeded the patient's PIF. All breathing effort indexes tested improved after HFNC treatment with the maximal unloading seen at 2 L/min/kg for PTP and at HFNC_NSS-MAES.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115443231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Important in the etiology of CD is the stiffening of the large arteries (arteriosclerosis) and plaque formation (atherosclerosis) in the common carotid artery (CCA). Increasing evidence shows that both arteriosclerosis and atherosclerosis can be detected by assessing pulse wave velocity (PWV) in the CCA, and several techniques focus on the detection of PWV in this structure. In previous studies, laser Doppler vibrometry (LDV) was proposed as an approach to detect arterial stiffness. In the present work, a compact four-channel LDV system is introduced for PWV detection. Four phantom arteries were assessed mimicking real life cardiovascular pathologies. Due to the high sensitivity and the increased spatial and temporal resolution of the LDV system, PWV could be assessed, and even local changes in phantom architecture could be detected. The system could potentially be used to detect arteriosclerosis and arterial plaque during cardiovascular screening.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125158938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For our heuristic approach, we used skeletal data to detect falls based on a set of instructions and signal filtering methods. For the machine learning approach, we implemented a dataset utilizing the Adaptive Boosting Trigger (AdaBoostTrigger) algorithm via video tagging to enable fall detection. For each approach, each subject on average has performed six true positive and six false positive fall incidents in two different conditions: one with objects partially blocking the sensor's view and one with partial obstructed field of view. The accuracy of each approach has been compared against one another in different conditions. The result showed an average of 95.42 % accuracy in the heuristic approach and 88.33 % in machine learning technique. We conclude that heuristic approach performs more accurately for fall detection when there is a limited number of training dataset available. Nevertheless, as the gesture detection's complexity increases, the need for a machine learning technique is inevitable.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126934511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the interaction between microwave (MW) and liver was simulated to predict tissue temperature distribution and damaged volume; then numerical simulations were experimentally validated. Simulations were performed: i) by considering the geometry of the MW antenna used during the experiments, ii) by implementing the Pennes' equation to calculate the temperature map within the tissue, and iii) by using Arrhenius model to calculate the damaged tissue. The model was validated by performing experiments on four ex vivo pig livers, which were treated using a 2.45 GHz antenna at 100 W for 4 min. Three custom probes were fabricated and calibrated to measure tissue temperature during MWA. These probes consist of a needle embedding one or more Fiber Bragg grating (FBG) sensors. The three probes embed a total of eight FBGs, hence tissue temperature during MWA was monitored at eight distances from the antenna. Simulated temperatures around the antenna agree with experimental data. Moreover, the predicted damaged volume agrees with the volume of coagulation experienced by the tissue undergoing MWA. In conclusion, the proposed thermometric probes allow performing distributed temperature measurement during MWA, as well as facilitate the insertion of the FBGs within the organ. The measurements show that the model is able to accurately predict MWA effects in an ex vivo pig liver.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132419047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
