Ventilation Strategies for Cardiac Arrest
(OPTIVO Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to improve the delivery of ventilations (breaths given to a person who is not breathing) during CPR for cardiac arrest patients. Researchers are testing two different air volumes, High Volume Ventilation and Low Volume Ventilation, to determine which is more effective in supporting heart and lung function during emergencies. The focus is on adults experiencing heart-related cardiac arrest, treated by paramedics using a ventilation monitor. This study will help develop better guidelines for providing breaths during CPR. As an unphased trial, it offers participants the chance to contribute to vital research that could enhance emergency care practices.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these ventilation strategies are safe for cardiac arrest patients?
A previous study linked using lower amounts of air during ventilation to better brain function and more ventilator-free days. This finding suggests that less air might ease the body's burden and aid recovery. Another study found that patients receiving less air had a lower risk of dying in the ICU compared to those receiving more air, indicating that less air could be a safer option.
However, current guidelines recommend using 500-600 milliliters of air during CPR, as this amount is believed to effectively fill the lungs. Research on the optimal way to provide air during CPR is still ongoing. Both lower and higher air volumes have shown some safety and effectiveness in past studies, but further research is needed to determine the best method.12345Why are researchers excited about this trial?
Researchers are excited about the ventilation strategies being tested for cardiac arrest because they could significantly enhance how patients are supported during emergencies. Traditional ventilation methods often focus on standardized volumes, but this trial explores both high and low volume ventilation to see which might better support heart function and improve patient outcomes. By tailoring ventilation volumes more precisely, the goal is to optimize oxygen delivery and potentially reduce the risk of further complications. This trial could pave the way for more personalized and effective emergency care protocols, offering new hope for patients experiencing cardiac arrest.
What evidence suggests that this trial's ventilation strategies could be effective for cardiac arrest?
Research has shown that using smaller breaths during CPR for cardiac arrest can lead to better outcomes. In this trial, participants will receive either a low-volume or high-volume ventilation strategy. Studies have found that patients who received smaller breaths had better brain function and spent fewer days on a ventilator. Another study found that patients who received the right amount of air had a higher chance of survival. Smaller breaths also help improve oxygen levels and reduce lung pressure during CPR. This evidence suggests that smaller breaths could be more effective in treating cardiac arrest patients.13678

Are You a Good Fit for This Trial?
This trial is for adults (18+) who have had a cardiac arrest outside the hospital, are being treated by paramedics, and do not have a DNR order. It excludes those with traumatic or respiratory-related cardiac arrests, pregnant individuals, prisoners, or anyone without ventilation monitoring.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial

What Are the Treatments Tested in This Trial?
Interventions
- High Volume Ventilation
- Low Volume Ventilation
Trial Overview
The study compares two ways of giving breaths during CPR—high volume versus low volume ventilation—to see which method improves survival after out-of-hospital cardiac arrest. Participants are randomly assigned to one of the two groups.
