Kapnometrija se vse bolj uporablja med anestezijo in intenzivno terapijo, kjer se uporablja kot nadomestek za določitev krvnih plinov ali za spremljanje umetne predihanosti bolnika. V izogib visokim vrednostim PETCO2 je namen magistrskega dela ugotoviti ali se pri visokih pretokih kisika zviša kopičenje CO2 v Sentri maski in ali obstaja razlika v PETCO2 med Sentri obrazno masko in obrazno masko, ki smo jo sami izdelali. Capnometry is used increasingly more in anaesthesia and intensive therapy where is useful as substitute for defining of blood gases or monitoring artificial ventilation of patient. We wish to avoid the effects of high flowrates of PETCO2 hence the purpose of this master thesis is to determine whether by high flowrates of oxygen increases accumulation CO2 in Sentri™ ETCO2 mask and if exists difference in measured PETCO2 betwen Sentri™ ETCO2 mask and face mask that we created.

V diplomskem delu smo raziskali uporabnost kapnometrije in kapnografije v nujnih stanjih. Pregled literature smo izvedli v bibliografski podatkovni bazi MEDLINE, kjer smo poiskali predvsem primarne znanstvene vire. Terciarni viri so vključevali učbenike in priročnike s področja urgentne medicine. V rezultatih smo sistematično klasificirali uporabnost kapnometrije, oziroma kapnografije v kronološkem vrstnem redu, glede na nastajanje CO2 in njegovega prenosa po krvi do pljuč in izdiha (celični metabolizem — cirkulacija — pljuča — dihanje — anatomske dihalne poti — umetne dihalne poti — dihalni sistemi — ventilator). Rezultati prikazujejo največjo uporabnost kapnografije pri določanju položaja sapničnega tubusa in poznejši kontroli le-tega. Glede na študijo literature, smo ugotovili, da medicinske sestre pri sedaciji bolnika poudarjajo pomen nadzora s pomočjo kapnografijo. Znanstvene objave na področju kapnometrije obsegajo predvsem prognostiko preživetja in oceno cirkulacije. V kratki raziskavi na vzorcu 20 študentov smo ugotovili, da imajo študentje FZV Maribor po končanem študiju o tem področju zelo malo znanja. Diplomsko delo smo zato namenoma zelo podkrepili s slikovnim materialom, da bi olajšali razumevanje vsebin iz področja kapnometrije in kapnografije. In our graduate work, we investigated the usefulness of capnometry and capnography in emergency medicine. We conducted a systematic review of this topic in the bibliographic database MEDLINE, where we find a primary scientific sources. Secondary scientific sources included textbooks and manuals in the field of emergency medicine. In the results, we systematically classify the usefulness of capnography and capnometry in chronological order, depending on the formation of CO2 and its transfer by the blood to the lungs and the breath (cellular metabolism - circulation - the lungs - breathing - anatomical airways - artificial airways - respiratory system - ventilator) . The results show the maximum utility of capnography in determining the position of the tracheal tube and the subsequent control of it. According to the study of literature, we found that nurses emphasize the importance of controlling the patient sedation through capnography. Scientific publications on the subject of capnometry include prognostic of survival and evaluation of circulation. In a short survey on a sample of 20 students, we found that students of the FZV Maribor after completion of studies they have very little knowledge in this field. Our graduate work, therefore, we very deliberately reinforced the image material, to facilitate understanding of the content of capnometry and capnography.
