简要总结
Evaluation of automated oxygen titration in comparison with manual adjustment oxygen in the out-of-hospital setting by paramedics.
详细描述
It is a single center study in Ottawa, Ontario Canada.
This will be a single centered prehospital multi-period cluster crossover feasibility trial, enrolling patients in Ottawa, Ontario, who are treated by paramedics from the Ottawa Paramedic Service, who have been trained in the use of the automated oxygen delivery device. We will be using the FreeO2 device. Patients requiring oxygen therapy during prehospital transportation will be enrolled. No randomization will occur within this single centered feasibility study
Patients requiring oxygen therapy during the prehospital transportation will be enrolled and will be included as soon as they are placed into the ambulance, until handover and transfer of care at receiving hospital.
In both groups, SpO2 will be collected continuously every second with FreeO2 monitoring, in addition to the collection of vital signs carried out by the staff according to the standards.

入选标准
- •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
排除标准
- •Inclusion in another study not allowing the co-enrollment
- •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).
研究组 & 干预措施
Control group
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.
干预措施: Standard administration of oxygen flow (Other)
FreeO2 group
The adjustment of the oxygen flow will be made by the FreeO2 system, an automated titration to reach the SpO2 target set by paramedic.
干预措施: Automated oxygen administration - FreeO2 (Device)
结局指标
主要结局
Feasibility of the study design - Paramedics survey
时间窗: through study completion, an average of 1 year
A survey will be complete by Paramedics at the end of day of transportation (day 1); the target response rate is 75% of case.
Feasibility of the study design - Evaluation of data collection tool
时间窗: through study completion, an average of 1 year
target: 100% of data captured in \>90% cases
Feasibility of the study design - REB approval
时间窗: Date of REB submission to date of REB approval, target: until 3 months (90 days) from REB submission
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
Feasibility of the study design - initiate the clinical trial
时间窗: Target until 3 months (90 days) from REB approval
Time to readiness to initiate the clinical trial
Feasibility of the study design - study protocol compliance
时间窗: through study completion,an average of 1 year
Target of 80% of compliance for protocol intervention/control group
