Overview

Brief Summary

The hypothesis of the present study is that restoring nasal stimulation alleviates dyspnea and improves respiratory drive. The aim of this study is to compare three non-pharmacological approaches designed to restore nasal stimulation (continuous nasal airflow, nasal sprays, and facial airflow) in tracheotomized patients dependent on mechanical ventilation.

Detailed Description

Nasal stimulation is generated by breathing, which enables olfaction and helps to rhythm brain activity. The loss of nasal stimulation in tracheotomized patients who are dependent on mechanical ventilation may negatively affect respiratory drive and contribute to dyspnea. Restoring nasal airflow therefore emerges as an attractive non-pharmacological approach to treat dyspnea in patients undergoing mechanical ventilation weaning.
