  1. 1. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Melina Al Nasser; Linn Gromert; [2022]
    Keywords : Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Abstract : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. READ MORE

  3. 2. The Acute Metabolic Response of Intermittent Hypoxic Resistance Exercise : A Cross-Over RCT

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Author : Jonas Falgin Hultgren; [2019]
    Keywords : Intermittent Resistaypoxic resistance exercise; lactate accumulation; cross-over RCT; RCT; Random Controlled Trial; healthy; men; blood; plasma; styrketräning; hypoxi; normoxi; saturation; laktat; ansamling; ph; blod; plasma; tung styrketräning; metabolisk; respons; randomiserad; kontrollerad; experiment; friska; unga; män; skelettmuskulatur;

    Abstract : Aim The aim for this present study was to investigate the acute metabolic response from intermittent resistance exercise during hypoxia, with the following research questions: (1) Are blood levels of lactate and glucose different between hypoxia and normoxia? (2) Does hypoxia induce higher lactate accumulation and pH reduction in the human skeletal muscle? (3) Is there a relationship between plasma-, blood- and muscle lactate? Method Eight healthy males (30 ± 2 years) performed 6 sets of unilateral leg extension on each leg (75% of 1RM) with randomized normoxic (20,9% inspired 𝑂2) and normobaric hypoxic (12% inspired 𝑂2) conditions. A total of 5 muscle biopsies was extracted from m. READ MORE

  4. 3. Detecting Cardiac Pulsatility and Respiration using Multiband fMRI

    University essay from Umeå universitet/Institutionen för fysik

    Author : Joakim Jonsson; [2018]
    Keywords : fMRI; multiband; cardiac pulsation; respiration; correlation analysis; neuroimaging;

    Abstract : Purpose: Arterial stiffening poses an increased risk of cerebrovascular diseases, cognitive impairments, and even dementia as cardiac pulsations reach further into the brain causing white matter hyperintensities and microbleeds. Therefore it is of interest to obtain methods to estimate and map cardiac related pulsatility in the brain. READ MORE

  5. 4. Accuracy Validation of Pulse Oximeters used at Hospitals : A Cross-Sectional Study performed in Stockholm

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Klara Andersson; Esther Busch Paulsson; [2017]
    Keywords : pulse oximeter; accuracy; arterial blood gas test; questionnaire; test; healthcare; pulsoximeter; mätnogrannhet; arteriellt blodgastest; enkät; test; sjukvård;

    Abstract : This thesis had the purpose to look into the accuracy of the pulse oximeter, the experienced as well as the actual. A pulse oximeter utilizes optics to non-invasively estimate the oxygen saturation (SO2) in the blood with an indirect value (SpO2). READ MORE

  6. 5. Motion artifact reduction in PPG signals

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jaqub Ghairat; Hassan Mouhsen; [2015]
    Keywords : Technology and Engineering;

    Abstract : The aim of this thesis was to investigate methods for artifact removal in PPG signals and to implement and evaluate a few existing algorithms claiming that the amplitude information is recovered when removing motion artifacts from photoplethysmographic signals (PPG) captured from pulse oximeters. We developed a new proposed method that uses a two-stage based approach with singular value decomposition and fixed fast ICA algorithm in order to generate a PPG-correlated reference signal that is used in adaptive noise cancellation.
