Clinical Trial Summary

Goal of our study is to investigate whether the implication of nasal positive airway pressure (nPAP) system on patients with high periprocedural risk could significantly lower the incidence of severe hypoxia and hypercarbia. Furthermore, we have set up goals to assess key components and factors, which lead to development of hypercarbia during endoscopy.

Description:

Sedation of high-risk patients resemble a relevant issue in interventional endoscopy.

This especially because standard oximetric monitoring displays only hypoxia and not the preceding hypercapnia. Therefore, the question arises whether the implication of a nasal positive airway pressure (nPAP) system can decrease the rate of sedation associated events.

The Null Hypothesis: The incidence of hypoxia in interventional group, using nasal positive airway pressure system, in comparison to control group with conventional oxygen supplementation canula is not significant.

Alternative Hypothesis: The incidence of hypoxia in interventional group, using nasal positive airway pressure system is significantly lower, than in a control group with conventional oxygen supplementation canula
