Effects on PaCO2 Levels of Two Different Nasal Cannula in COPD Patients

NCT05528289 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

No results posted yet for this study

Summary

High-flow nasal cannula (HFNC) therapy is increasingly used in the management of acute respiratory failure. Its clinical application has been expanded also in other specific settings In stable COPD patients and in those recovering from acute exacerbation, HFNC can reduce PaCO2, respiratory rate, minute ventilation and respiratory effort.

The aim of this randomized crossover physiological study is to investigate the effects on PaCO2 levels of two different nasal cannula ('Optiflow + Duet' interface vs "standard" nasal interface) in COPD patients with persistent hypercapnia following an acute severe exacerbation

Conditions

Interventions

DEVICE

AIRVO 2, with conventional symmetric nasal cannula

The patients will be asked to breathe with HFNC at flow of 40 L/min with the standard cannula The size of nasal cannula will be selected to occlude patient's nostril of about 2/3. Temperature will be set according to the patient's tolerance starting from 31°C, up to 37°C, while FiO2 is adjusted to maintain SpO2 between 88 and 92%.

DEVICE

AIRVO 2, the new asymmetric nasal cannula

The patients will be asked to breathe with HFNC at flow of 40 L/min with the new asymmetric nasal cannula The size of nasal cannula will be selected to occlude patient's nostril of about 2/3. Temperature will be set according to the patient's tolerance starting from 31°C, up to 37°C, while FiO2 is adjusted to maintain SpO2 between 88 and 92%.
