E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Demonstrate that High Flow Nasal Cannula Therapy (HFNCT), with a minimal flow of 40L/min, in COPD exacerbated patients, without respiratory acidosis, seen at Emergency Service, reduces dyspnea, respiratory frecuency (RF) and breathing work without producing, at the same time, an increase of carbon dioxide arterial blood pressure (PaCO2) during the first 24 hours, in respect to Convencional Oxygen Therapy (OCT). |
Demostrar que la Terapia con Cánula Nasal de Alto Flujo (TAFCN), con un flujo mínimo de 40L/min, en pacientes EPOC exacerbados, sin acidosis respiratoria, atendidos en el Servicio de Urgencias, reduce la disnea, la frecuencia respiratoria (FR) y el trabajo respiratorio sin producir, al mismo tiempo, un aumento de la presión arterial de dióxido de carbono (PaCO2) durante las primeras 24 horas, respecto a la Oxigenoterapia Convencional (OTC). |
|
E.2.2 | Secondary objectives of the trial |
- To demonstrate that HFNCT, with a minimal flow of 40L/min, in exacerbated COPD patients without respiratory acidosis seen at Emergency Service, reduces dyspnea, RF and breathing work, without simultaneously producing an increase of PaCO2 in the first 3 days of admission in comparison to COT. - To demonstrate that HFNCT, with a minimal flow of 40L/min, in exacerbated COPD patients without respiratory acidosis seen at Emergency Service, reduces hospitalization days, mortality at 30 and 60 days, risk for poor evolution and number of annual exacerbations in comparison to COT. - To demonstrate that HFNC, with a minimal flow of 40L/min, in patients with acute COPD without respiratory acidosis seen at Emergency Service, decreases PaCO2 at 6 and 12 months in comparison to COT. |
- Demostrar que la TAFCN, con un flujo mínimo de 40L/min, en pacientes con EPOC agudizada, sin acidosis respiratoria, atendidos en Urgencias, reduce la disnea, la FR y eltrabajo respiratorio, sin que se produzca simultáneamente un aumento de la PaCO2 en los 3 primeros días de ingreso respecto al OTC. - Demostrar que la TAFCN, con un flujo mínimo de 40L/min, en pacientes con EPOC agudizada sin acidosis respiratoria atendidos en Urgencias, reduce los días de hospitalización, la mortalidad a los 30 y 60 días, el riesgo de mala evolución y el número de agudizaciones anuales en comparación con OTC. - Demostrar que la TAFCN, con un flujo mínimo de 40L/min, en pacientes con EPOC aguda, sin acidosis respiratoria, atendido en Urgencias, disminuye PaCO2 a los 6 y 12 meses respecto al OTC. |
