   Sammanfattning : Perioperative hypotension corresponds to critically low blood pressure events during the pre, intra and postoperative periods. It is a common side effect of general anaesthesia and is strongly associated with an increased risk of postoperative complications, such as acute kidney injury, myocardial injury and in the worst case death.

   Sammanfattning : Perioperative hypotension (PH), commonly a side effect of anesthesia,is one of the main mortality causes during the 30 posterior days of asurgical procedure. Novel research lines propose combining machinelearning algorithms with the Arterial Blood Pressure (ABP) waveform tonotify healthcare professionals about the onset of a hypotensive event withtime advance and prevent its occurrence.

4. 3. Concentrations of inflammatory markers and clinical findings in bitches surgically treated for pyometra in Khon Kaen, Thailand

   Master-uppsats, SLU/Dept. of Clinical Sciences

   Författare :Anna Ahlén; [2017]
   Nyckelord :albumin; iron; C-reactive protein; pyometra; biomarkers; SIRS; sepsis;

   Sammanfattning : Pyometra is a common reproductive disease affecting intact bitches. The disease is defined by accumulation of purulent material within the uterus, and can potentially be life-threatening. Clinically, affected bitches can present with a variety of signs and diagnosis can be challenging in more indistinct cases. LÄS MER

5. 4. Motion artifact reduction in PPG signals

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Jaqub Ghairat; Hassan Mouhsen; [2015]
   Nyckelord :Technology and Engineering;

   Sammanfattning : 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.
