COPD Exacerbation Acute
Conditions
Brief summary
COPD is a heterogeneous condition caused by airway (bronchitis/bronchiolitis) or alveolar (emphysema) abnormality, changes with chronic respiratory changes (dyspnea, dyspnoea, phlegm). It is characterized by persistent and frequently progressive airway obstruction. In COPD, which progresses with high mortality, non-pharmacological treatments are applied, as well as pharmacological treatments. They have an essential place in slowing down the progressive course of this treatment. However, despite the treatment administered to COPD patients, outdoor weather conditions, improper use of inhaler treatments, or comorbidities may cause acute exacerbation of COPD. Dry air nebulizer devices use dry air from the central system in hospitals. This system, which converts bronchodilator drugs into nebulizers by creating high currents, works like classical nebulizers without an electrical system and can have a higher flow rate than jet nebulizer devices. This procedure, which can be applied to COPD patients without giving high-flow oxygen, prevents carbon dioxide retention. There is no study in the literature comparing the bronchodilator effectiveness of dry air, classical nebulizer, and jet nebulizer, and the investigators aimed to compare the efficacy of these three treatment modalities in our study.
Interventions
DEVICEComparison of bronchodilator effectiveness of nebulizer therapy devices
The Respirox® RNEB-18 device was used for the bronchodilator treatment given before the randomization of the patients and for the maintenance bronchodilator treatment given in Group 1 patients. After calibrating the device, it was determined that it performed nebulization with a flow of 6 lt/min. In Group 2 patients, a HAVELSAN® EHSİM brand nebulizer produced in our country, compatible with the central system of our hospital, was used as a dry air nebulizer. For classical nebulizer treatment in Group 3 patients, a nebulizer device compatible with our hospital's central oxygen system was used. In Group 2 and 3 patients, the flow system could be adjusted manually. To be consistent with Group 1 patients, bronchodilator treatment was administered at a 6 lt/min flow rate.
