Outcome Measures

Primary Outcomes (5)

  • Feasibility of the study design - REB approval

    Time to REB approval for single site time to REB approval for single site define by below 3 months (90 days) from REB submission, time to readiness to initiate the clinical trial after REB approval - below 3 months (90 days) from REB approval, evaluation of data collection tool - 100% of data captured in \>90% case at hospital discharge (until day 28), Survey responses from Paramedics - At the end of the transportation day

    Date of REB submission to date of REB approval, target: until 3 months (90 days) from REB submission

  • Feasibility of the study design - initiate the clinical trial

    Time to readiness to initiate the clinical trial

    Target until 3 months (90 days) from REB approval

  • Feasibility of the study design - Evaluation of data collection tool

    target: 100% of data captured in \>90% cases

    through study completion, an average of 1 year

  • Feasibility of the study design - study protocol compliance

    Target of 80% of compliance for protocol intervention/control group

    through study completion,an average of 1 year

  • Feasibility of the study design - Paramedics survey

    A survey will be complete by Paramedics at the end of day of transportation (day 1); the target response rate is 75% of case.

Study Arms (2)

Control group

ACTIVE COMPARATOR

In this group, the - usual care based upon BLS-PCS with manual titration of oxygen. In this group the SpO2 was recorded any time with FreeO2 device - recording mode.

Other: Standard administration of oxygen flow

FreeO2 group

EXPERIMENTAL

The adjustment of the oxygen flow will be made by the FreeO2 system, an automated titration to reach the SpO2 target set by paramedic.

Device: Automated oxygen administration - FreeO2

Interventions

The adjustment of the oxygen flow will be made by the FreeO2 system, an automated titration of oxygen flow every second to reach the SpO2 target. The SpO2 target will be set at 90% in COPD patients and 94% in trauma patients.

FreeO2 group

The flow of oxygen will be administered according to the usual protocol during the transport and until transfer to the emergency departement.

Control group

Eligibility Criteria

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • COPD patient:
  • Known or suspected acute exacerbation of COPD. Acute exacerbation is defined by worsening of the respiratory condition for less than 2 weeks. Suspected COPD is defined by patients of at least 30 years old with respiratory symptoms with a past or current smoking history of at least 10 pack years, or
  • Able to measure SpO2 via pulse oximetry
  • Trauma patient:
  • I) Trauma: patients who sustain any trauma (minor or major), II) Able to measure SpO2 via pulse oximetry

You may not qualify if:

  • Pregnancy
  • Age \<18 years
  • Prehospital Invasive or non-invasive mechanical ventilation
  • Meeting high concentration oxygen administration injury or condition (as per BLS-PCS Oxygen Therapy Standard (Version 3.0), s(2)a-f).
