Outcome Measures

Primary Outcomes (3)

  • Heart Rate

    The closest value of Heart Rate before starting HFNC, and two hours later was collected from the electronic clinical history.

    2 hours

  • Respiratory Rate

    The closest value of Respiratory Rate before starting HFNC, and two hours later was collected from the electronic clinical history.

    2 hours

  • Dyspnea

    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).

    2 hours

Secondary Outcomes (8)

  • Initial HFNC setting

    2 hours

  • Acute respiratory failure etiology

    3 minutes

  • Average time of use the HFNC

    until 28 days

  • Delay of HFNC treatment

    until 24hs

  • Efficacy of HFNC treatment

    28 days

  • +3 more secondary outcomes

Interventions

The high flow device that we used was an air oxygen blender (Whisper FlowⓇ), which allows FiO2 adjustment between 0.30 and 1.0 and can deliver a gas flow from 10 to 150 l/min. The gas mixture was routed from a heated humidifier (MR850 with MR 290 chamber) through a one line heated inspiratory circuit (RT241) to the subject at a temperature of 37°C via a nasal cannula (OptiflowⓇ).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with and without a history of lung disease who used high flow nasal cannula. We defined 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.

You may qualify if:

  • patients aged ≥ 18 years
  • attended between July 1st, 2015 and January 31st , 2017 in the Emergency Department of the Hospital Italiano de Buenos Aires
  • with clinical signs of acute respiratory failure

You may not qualify if:

  • \- Pulse oximetry \> 90% breathing room air
