  • telemedicine system for remote blood pressure and heart rate Monitoring
    E-Health and Bioengineering Conference, 2011
    Co-Authors: Cristian Rotariu, H Costin, Felix Adochiei, Alexandru Pasarica, Razvan Ciobotariu
    Abstract:

    In this paper we present the realization of a remote blood pressure and heart rate Monitoring system, based on wireless devices, capable to measure and transmit patient's arterial blood pressure and heart rate. The use of the proposed system is suitable for continuous long-time patient Monitoring, as a part of a diagnostic procedure. The patient can achieve medical assistance of a chronic condition, or can be supervised during recovery from an acute event or surgical procedure. We use commercially available devices, low power microcontrollers and RF transceivers that perform the measurements and transmit them to the patient Monitoring device. The patient Monitoring device, in form of a PDA that running a personal heart Monitor Application, receives the blood pressure systolic and diastolic values and heart rate, activates the alarms when these values exceed the preset limits, and communicates periodically to the central Monitoring server by using WiFi or GSM/GPRS connection. A graphical user interface running on the central Monitoring server for displaying the measurements was developed. Power consumption by the used devices was also minimized.

  • An integrated system for wireless Monitoring of chronic patients and elderly people
    15th International Conference on System Theory Control and Computing, 2011
    Co-Authors: Cr Rotariu, H Costin, Razvan Ciobotariu, Gladiola Andruseac, Felix Adochiei
    Abstract:

    In the last years the demographic changes and ageing of population increase health care demand. Increasing number of chronic patients and elders requires close attention to their health conditions. In this paper we present the realization of a wireless Monitoring system capable to measure process and transmit patient's physiologic signals (electrocardiogram, respiratory rhythm, arterial saturation of oxygen, blood pressure and body temperature) to a central medical server. The use of our system is suitable for continuous long-time Monitoring, as a part of a diagnostic procedure or can achieve medical assistance of a chronic condition. We use custom developed and commercially available devices, low power microcontrollers and RF transceivers that perform the measurements and transmit them to the Personal Server. The Personal Server, in form of a PDA, that running a Monitor Application, receives the physiological signals from Monitoring devices, activates the alarms when the Monitored parameters exceed the preset limits, and communicates periodically to the central server by using WiFi or GSM/GPRS connection.

  • 4th European Conference of the International Federation for Medical and Biological Engineering
    IFMBE Proceedings, 2009
    Co-Authors: Cr Rotariu, H Costin, D Arotaritei, Mónica De La Fuente, Robert Elfring, W. Teske, Gabriel Constantinescu, Frank Schmidt, Klaus Radermacher
    Abstract:

    the current common goal in medical information technology today is the design and implementation of telemedicine solutions, which provide to patients services that enhance their quality of life. Recent technological advances in sensors, low-power integrated circuits, and wireless communications have enabled the design of low-cost, miniature, and intelligent physiological sensor modules. These modules are capable of measuring, processing, communicating one or more physiological parameters, and can be integrated into a wireless personal area network (WPAN). In this paper we present the realization of a wireless personal area network for patient Monitoring, as a part of a telemedicine system, capable to measure and transmit physiological parameters such us blood pressure, heart rate, respiratory rhythm, pulse oximetry SpO2, body temperature, and three ECG leads. The use of WPAN is suitable for continuous long-time patient Monitoring as a part of a diagnostic procedure, can achieve medical assistance of a chronic condition, or can be supervised during recovery from an acute event or surgical procedure. For instance, the computer-assisted rehabilitation involves unwieldy wires between sensors and Monitoring device that are not very comfortable for normal activity. We use the intelligent wireless sensors, based on low power microcontrollers and RF transceivers that perform the measurements and computes the physiological parameters. Individual sensor Monitors specific physiological parameter and communicates with the personal server. Personal server, in form of a wireless PDA that running a personal health Monitor Application, receives the information from wireless sensors, activates the alarms when the measured parameters are above the limits, and communicates periodically to the central server (part of the telemedicine system) by using WiFi or GSM/GPRS connection. The Monitor reacts to potential health risks and records physiological information into a local database. © 2009 Springer Berlin Heidelberg.

  • wireless system for remote Monitoring of oxygen saturation and heart rate
    Federated Conference on Computer Science and Information Systems, 2012
    Co-Authors: Cristian Rotariu, Vasile Manta
    Abstract:

    This paper describes the realization of a wireless oxygen saturation and heart rate system for patient Monitoring in a limited area. The proposed system will allow the automatic remote Monitoring in hospitals, at home, at work, in real time, of persons with chronic illness, of elderly people, and of those having high medical risk. The system can be used for long-time continuous patient Monitoring, as medical assistance of a chronic condition, as part of a diagnostic procedure, or recovery from an acute event. The blood oxygen saturation level (SpO 2 ) and heart rate (HR) are continuously measured using commercially available pulse oximeters and then transferred to a central Monitoring station via a wireless sensor network (WSN). The central Monitoring station runs a patient Monitor Application that receives the SpO 2 and HR from WSN, processes these values and activates the alarms when the results exceed the preset limits. A user-friendly Graphical User Interface was developed for the patient Monitor Application to display the received measurements from all Monitored patients. A prototype of the system has been developed, implemented and tested.

  • Wireless system for remote Monitoring of atrial fibrillation
    2012 5th European DSP Education and Research Conference (EDERC), 2012
    Co-Authors: Cristian Rotariu, Dragos Arotaritei, Vasile Manta
    Abstract:

    In this paper is described the design and implementation of a wireless atrial fibrillation Monitoring system, for realtime remote patient Monitoring in a limited area, using wireless sensor networks (WSN). The proposed system consists of a lightweight and low power wireless ECG acquisition and processing device, connected to a central Monitoring station through WSN. The device is able to detect the paroxysmal atrial fibrillation episodes and transmits alerts to the central Monitoring station. The system can be used for long-time continuous Monitoring of patients suspected to have atrial fibrillation, as part of a diagnostic procedure, or recovery from an acute or surgical event. In order to detect the atrial fibrillation episodes we used a simple method based on RR intervals, extracted from ECG signal. We evaluated the performance of the method on MIT-BIH Atrial Fibrilation Database from Physionet. The central Monitoring station runs a patient Monitor Application that receives the real time heart rate and atrial fibrillation alerts from WSN. A user-friendly Graphical User Interface was developed for the patient Monitor Application to display the heart rate and alerts coming from the Monitored patient. A prototype of the system has been developed, implemented and tested.

  • Qualitative metabolism assessment and toxicological detection of xylazine, a veterinary tranquilizer and drug of abuse, in rat and human urine using GC–MS, LC–MS^ n , and LC–HR-MS^ n
    Analytical and Bioanalytical Chemistry, 2013
    Co-Authors: Golo M. J. Meyer, Hans H. Maurer
    Abstract:

    Xylazine is used in veterinary medicine for sedation, anesthesia, and analgesia. It has also been reported to be misused as a horse doping agent, a drug of abuse, a drug for attempted sexual assault, and as source of accidental or intended poisonings. So far, no data concerning human metabolism have been described. Such data are necessary for the development of toxicological detection methods for Monitoring drug abuse, as in most cases the metabolites are the analytical targets. Therefore, the metabolism of xylazine was investigated in rat and human urine after several sample workup procedures. The metabolites were identified using gas chromatography (GC)–mass spectrometry (MS) and liquid chromatography (LC) coupled with linear ion trap high-resolution multistage MS (MS^ n ). Xylazine was N-dealkylated and S-dealkylated, oxidized, and/or hydroxylated to 12 phase I metabolites. The phenolic metabolites were partly excreted as glucuronides or sulfates. All phase I and phase II metabolites identified in rat urine were also detected in human urine. In rat urine after a low dose as well as in human urine after an overdose, mainly the hydroxy metabolites were detected using the authors’ standard urine screening approaches by GC–MS and LC–MS^ n . Thus, it should be possible to Monitor Application of xylazine assuming similar toxicokinetics in humans. Figure Reconstructed high-resolution mass chromatograms indicating xylazine and its phase I metabolites as well as the mass spectra with structures of xylazine and one of its hydroxy metabolites
