Various complications are the leading cause of morbidity in sedation practices in endoscopic procedures, and guidelines recommend continuous monitoring of circulation, respiratory function, and ventilation. Integrated Pulmonary Index (IPI), one of the methods that can be used in this monitoring, gives a single numerical value obtained by continuous and simultaneous joint mathematical analysis of Oxygen saturation, End-tidal carbon dioxide concentration, respiratory rate, and heart rate values and is a good monitorization in these interventions. and provides tracking. In this study, the aim is to determine the role of IPI in the diagnosis and follow-up of respiratory complications in patients who were sedated during gastroscopy procedures.

IPI EtCO2 is a monitoring method consisting of respiratory rate, SPO2 and heart rate parameters. While EtCO2 is measured with nasal capnography, SPO2, heart rate, respiratory rate are measured with finger probe and it will show instant measurement of respiratory status. IPI takes values between 1-10. An IPI value of 8 and above will indicate normal values, a value between 5-7 will indicate that the respiratory status of the patient should be carefully examined and intervened if necessary, values of 4 and below will definitely indicate that the patient's respiratory status should be intervened.

Blood pressure measurement will be made with a sphingmomanometer noninvasively at certain time intervals with the help of a cuff that will be placed on the patient's arm area.
