简要总结
High-flow nasal cannula (HFNC) enables delivering humidified gas at high-flow rates controlling the oxygen inspired fraction (FiO2). Its efficacy has been demonstrated in hypoxemic acute respiratory failure. However, little is known about its use in hypercapnic acute respiratory failure (ARF). Therefore, we aimed to evaluate the effect of using HFNC through "Precision Flow" equipment as first line of ventilatory support for COPD patients with hypercapnic acute respiratory failure.

入选标准
- •Moderate to very severe COPD patients (GOLD 2 to 4) over 18 years old admitted to the ICU with hypercapnic ARF (PaCO2> 45 mmHg and respiratory acidosis [pH ≥7.30], with or without hypoxemia + one of the following: Respiratory Rate ≥25 cycles per minute, intercostal and / or supraclavicular recruitment, or thoraco-abdominal synchrony, no prior use of NIV)
排除标准
- •Patients less than 18 years old
- •Mild COPD patients
- •Absence of hypercapnia
- •Kelly M Score > 3
- •Haemodynamic instability (despite fluid resuscitation)
- •NIV or Invasive Mechanical Ventilation (IMV) (Need to use previously to HFNC)
- •Contraindications to implement high-flow oxygen therapy.
结局指标
主要结局
Need for endotracheal intubation
时间窗: From inclussion study date until the first day of endotracheal intubation documented, after high flow oxygen therapy use or death date from any cause, whichever came first, assessed up to 4 weeks.
The need and causes for endotracheal intubation will be recorded in the all study period.
Need for non-invasive ventilation
时间窗: From inclussion study date until the first day of noninvasive ventilation use documented, after high flow oxygen therapy use or death date from any cause, whichever came first, assessed up to 4 weeks.
The need and causes for non-invasive ventilation will be recorded in the all study period.
次要结局
- Gas Exchange(Arterial blood gases will be recorded 1, 24 hours and every 24 hours after enrollment)
- Patient's discomfort(Patient's discomfort will be recorded at 1, 2, 3, 6, 12, 24 hours and every 24 hours after enrollment)
- Respiratory variables(Respiratory variables will be recorded at 1, 2, 3, 6, 12, 24 hours and every 24 hours after enrollment)
