“…Chest radiography has been suggested as a rapid confirmative tool for ETT proper position (Schmolzer & Roehr, 2014). It was emphasized that the golden tools for ETI proper confirmation are through using manufactured devices as capnography for detection of end-tidal carbon dioxide (EtCO 2 ) (Sun et al, 2014) and pulse oximeters that measure the hemoglobin saturation (Das, Choupoo, Haldar, & Lahkar 2015;Jordan, Ham, & Fataar, 2015). Other methods for ETT confirmation include direct palpation of the suprasternal notch, manual cuff palpation, auscultation of chest and palpation of symmetrical chest movements, and esophageal detector devices (Jordan et al, 2015).…”
