    Sammanfattning : The lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) play a central role in preventing regurgitation and aspiration. The aim of this thesis was to evaluate the UES, LES, esophageal (E) and barrier (Br) pressures (P) using high resolution solid state manometry (HRSM). LÄS MER

    Sammanfattning : Pulse oximeters monitor non-invasively the haemoglobin oxygen saturation. Light of two specific wavelengths, red and infrared light, is shined through a tissue, usually the finger, and the intensity of the light transmitted is measured. Oxyhaemoglobin absorbs the light differently when compared to reduced haemoglobin. LÄS MER
