About this study
Official title: Comparing Known Modes of Ventilation Delivered by Trilogy Versus Conventional Mechanical Ventilators
The objective of this study (Part II) will be to compare the performance of the Trilogy device and a conventional ventilator (participant's current device). Both devices will be set to the participants' current mode and prescription settings.
Read the detailed description
- Primary Hypothesis and end-point In patients with respiratory insufficiency, when compared to conventional ventilators, the Trilogy device achieves comparable level of gas exchange (measured as partial pressure of CO2 in arterial or venous blood)and SpO2 levels during various modes of ventilation.
- Secondary Hypothesis and end-points In patients with respiratory insufficiency, when compared to conventional ventilators, the Trilogy device achieves comparable breathing pattern (tidal volume, respiratory rate, minute ventilation), hemodynamics (heart rate), and subjective measures of breathing comfort (measured by modified Borg dyspnea scale).
- Conditions
- Respiratory Insufficiency, Respiratory Failure
- Being tested
- Trilogy, Standard of Care
- Medical subject headings

What is being measured
The primary outcome is the main question the study is designed to answer.
Comparable Level of Gas Exchange (Measured as Partial Pressure of CO2 in Arterial or Venous Blood).
Blood gas was obtained for this study one hour after use of each device.
Measured: After one hour of ventilator use
Comparable Level of Gas Exchange SpO2 Levels During Various Modes of Ventilation.
Pulse Oximetry was measured after one hour of use of each ventilator.
Measured: After one hour of ventilator use
Secondary outcomes (3)
Tidal Volume
Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle. It measures around 500 mL in an average healthy adult male and approximately 400 mL in a healthy female. Average tidal volume was compare after a hour of use of each device.
Measured: One hour during ventilator use.
Minute Ventilation
Minute ventilation is the volume of gas inhaled or exhaled from a person's lungs per minute. This was measured after one hour of use of each device.
Measured: One hour during ventilator use.
Hemodynamics (Heart Rate)
Number of beats per minute. Measured after one hour of use of each device.
Measured: One hour during ventilator use.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Comparable Level of Gas Exchange (Measured as Partial Pressure of CO2 in Arterial or Venous Blood). (time frame: After one hour of ventilator use). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
