Study summary

Acute Hypoxemic Respiratory Failure (AHRF) is one of the prevalent causes of admission around the world and is associated with high mortality in resource-limited settings. Limited access to invasive mechanical ventilation is among the contributing factors to poor outcomes. The Bag CPAP may be useful in reducing the need for intubation and therefore mortality in patients with AHRF but data are lacking. This study aims to determine whether the Bag CPAP compared to standard oxygen care, could reduce the percentage of patients with criteria for intubation in patients with AHRF.

This is a prospective randomized, open-label, controlled trial in which patients presenting at the emergency room in Rwanda will be randomly assigned to receive standard oxygen therapy or Bag CPAP. The primary endpoint is the percentage of patients with criteria for intubation at day 7. Secondary endpoints include the tolerance of the Bag CPAP, overall 28-day mortality rate, mortality rate of intubated patients on mechanical ventilation at day 28, percentage of patients intubated at 28 days, ventilator-free days at day 28, interval between the initiation of treatment and the onset of intubation criteria, the interval between the time when criteria for intubation are met and intubation, organ failure-free days at day 7 and length of hospital stay.

In context

Respiratory Insufficiency

1,369 studies on the registry are indexed under Respiratory Insufficiency; 264 are open to participants now.

This study's planned enrollment of 250 is above the median of 60 across 860 interventional studies indexed under Respiratory Insufficiency.

Inclusion criteria

All patients aged 18 years or older will be included in the study if they meet the following criteria:

  • De novo acute respiratory distress, characterized by the presence of dyspnea at rest, the use of accessory muscles for breathing, or a respiratory rate of 25 cycles per minute or more.
  • Hypoxemia, defined as a SpO2/FiO2 ratio less than 315 or a PaO2/FiO2 ratio less than 300 mmHg (if arterial blood gas is available) despite an oxygen therapy of 6 L/min. FiO2 will be estimated by the rule of 3% (Coudroy formula)(18,22). SpO2 should be less than 98% when assessing the SpO2/FiO2 ratio.

Exclusion criteria

Patients with one of the following criteria will be excluded from the study:

  • Absolute to CPAP: patient's refusal, uncontrollable vomiting, upper gastrointestinal bleeding, open or sucking chest wound, pneumothorax not drained, craniofacial trauma, severe burns to the face, severe upper airway obstruction, traumatic tetraplegia at the initial stage, tracheostomy.
  • Moderate to massive pleural effusion not drained
  • Cardiac arrest, severe ventricular arrhythmias, and shock defined as the need for vasopressor support (adrenaline, noradrenaline, or dopamine)
  • Altered level of consciousness (GCS below 12), repetitive convulsions, or status epilepticus
  • Do not intubate or resuscitate order before the inclusion in the study
  • Refusal to participate, already included in the study, enrollment in another interventional trial on acute respiratory failure
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

  • Active comparator
    Oxygen

    Patients will receive oxygen

    Device: Standard oxygen

Interventions

  • DeviceBag CPAP

What researchers measure

Primary outcomes

  1. Percentage of patients with criteria for intubation at day 7

    Predetermined criteria for endotracheal intubation and mechanical ventilation will be considered.

    Time frame: Day-7

Secondary outcomes

  1. Tolerance of the Bag CPAP

    Percentage of patients with facial skin abrasion and necrosis, aspiration, or sinusitis up to day 28.

    Time frame: up to day-28

  2. Mortality rate of intubated patients on mechanical ventilation

    Invasive mechanical ventilation is defined as the delivery of positive pressure via an endotracheal or tracheostomy tube.

    Time frame: Up to day-28

  3. Ventilator-free days

    Time frame: up to day-28

  4. Organ failure-free days

    Time frame: Day-7

  5. Mortality rate

    Time frame: Up to day-28

  6. Duration of hospital stay

    Time frame: Up to day-28

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Apr 2026; primary completion for Feb 2027, 10 months later.

Of 359 non-industry interventional studies with no phase under Respiratory Insufficiency, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 47. This study's planned 10 months is below that.

Counting every sponsor, half of 375 studies reached it within 24 months; a quarter within 10 and three quarters within 46.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 19, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
