简要总结
The aim of this study was to describe the changes in respiratory rate, heart rate and dyspnea, before and after using HFNC in patients presenting to our emergency department with ARF.
详细描述
A retrospective cohort study was performed. To all adults presenting to the emergency department who used high flow nasal cannula to treat clinical signs of acute respiratory failure based on the presence of a breathing frequency ≥ 25 breath/min and increase work of breathing evidence by dyspnea, in-drawing, accessory-muscle use and/or diaphoresis despite conventional oxygen therapy ≥ 6 l/min. Demographic variables and clinical and gasometric parameters before and after two hours using HFNC were recorded.

结局指标
主要结局
Heart Rate
时间窗: 2 hours
The closest value of Heart Rate before starting HFNC, and two hours later was collected from the electronic clinical history.
Dyspnea
时间窗: 2 hours
The closest value of Dyspnea (Modified Borg Dyspnea scale) before starting HFNC, and two hours later was collected from the electronic clinical history. The Modified Borg Dyspnea Scale is a rated numerical score used to measure dyspnea. This scale has a minimum value of 0 ( represent no dyspnea) and a maximum value of 10 (worse dyspnea).
Respiratory Rate
时间窗: 2 hours
The closest value of Respiratory Rate before starting HFNC, and two hours later was collected from the electronic clinical history.
次要结局
- Delay of HFNC treatment(until 24hs)
- Failure of HFNC treatment(28 days)
- Average time of use the HFNC(until 28 days)
- Initial HFNC setting(2 hours)
- Acute respiratory failure etiology(3 minutes)
- Efficacy of HFNC treatment(28 days)
- Palliative Care(28 days)
- Mortality rate at 28 day from ED admission(28 days)
