Physiological responses to endotracheal and oral suctioning in paediatric patients: the influence of endotracheal tube sizes and suction …
Objective: To study the influence of varying outer suction heter (SC) diameter (OD) to inner endotracheal tube (ETT) diameter (ID) and suction pressures (SP) on heart rate (HR), respiratory rate (RR), mean arterial pressure (MAP), arterial oxygen saturation (SaO 2) and intracranial pressure (ICP) during ETT and oral suctioning.
