Comparison of pulse oximeters
Karafiátová, Pavla ; Harabiš, Vratislav (referee) ; Kolář, Radim (advisor)
This work deals with the pulse oximetres. The thesis describes the methods of measuring oxygen in blood and basic parts of pulse oximeter. It follows introduction to light absorbancy based on Beer’s law and its usage in pulse oximetry. The thesis also describes different probes and its properties and also algorithms for signal processing. Measuring and evauating on tester SECULIFE and volunteers is part of this thesis.

Complete implementation of pulse oximeter
Doležal, Lukáš ; Kaller, Ondřej (referee) ; Šotner, Roman (advisor)
This thesis deals with the design of a pulse oximeter. The resulting device allows to measure human blood oxygen saturation and heart rate in a non-invasive way. Easy portability is enabled by battery power supply and the used colour graphical display ensures clear display of the measured data. The paper describes in general terms the principle of pulse oximetry, a description of the chosen electronic components and the firmware developed to ensure the device's operation. Verification of correct operation was performed by comparing the measurements with similar devices available on the market.
