On-Demand Oxygen Therapy for Patient Monitoring
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new oxygen delivery method that flows only when inhaling, rather than continuously. Researchers aim to determine if this method, called the On Demand Oxygen Delivery System, improves blood oxygen levels and enhances the accuracy of carbon dioxide monitoring during medical procedures. Participants will alternate between the new and traditional oxygen delivery methods to assess effectiveness. The trial seeks relatively healthy individuals undergoing procedures requiring sedation, without serious lung or heart conditions. As an unphased trial, it offers participants the chance to contribute to innovative research that could enhance oxygen delivery in medical settings.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this on-demand oxygen delivery system is safe for patient monitoring?
Research has shown that the On Demand Oxygen Delivery System can help patients. One study found that this system improved oxygen levels in people with breathing problems. It is safe for home use and carries a low risk of complications.
Traditional oxygen delivery systems are also generally safe. Studies have indicated that providing oxygen after surgery can prevent low oxygen levels. However, excessive oxygen during surgery might lead to risks such as lung or heart issues.
Overall, both oxygen delivery systems have been used safely in various situations. The On Demand System may offer benefits in managing oxygen levels more effectively.12345Why are researchers excited about this trial?
Researchers are excited about the On Demand Oxygen Delivery System because it offers a smarter way to provide oxygen during surgical procedures. Unlike traditional systems that deliver a constant flow of oxygen, this system delivers oxygen only when needed—either for 20 seconds or after 3 breaths, whichever comes first. This approach helps conserve oxygen, reduce waste, and potentially improve patient comfort by avoiding unnecessary oxygen exposure. The trial aims to demonstrate how this method could lead to more efficient and personalized oxygen delivery during surgeries.
What evidence suggests that the On Demand Oxygen Delivery System is effective for improving oxygen saturation and end-tidal oxygen levels?
Research has shown that a demand oxygen delivery system, which provides oxygen only during inhalation, can improve blood oxygen levels. One study found that this method increased both the oxygen in the blood and the oxygen exhaled. This system has also effectively treated low blood oxygen levels (hypoxemia) at rest and during exercise.
In this trial, participants will use both the demand oxygen delivery system and the traditional oxygen delivery system, which provides a constant oxygen flow. Traditional systems are often used to prevent low oxygen levels after surgery, but studies have shown they might not always improve outcomes like reducing infections or breathing problems. The demand system could offer a more efficient way to deliver oxygen when needed most.36789Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for relatively healthy patients undergoing sedation and pain relief during procedures, who are classified as ASA class I-III. It's not suitable for those with oxygen saturation below 93% on room air, severe lung or heart conditions, pregnant women, very high-risk surgery patients (ASA class IV+), short procedures under 20 minutes, or individuals under 18.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive alternating oxygen delivery modes (demand and continuous flow) during the surgical procedure
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- On Demand Oxygen Delivery System
- Oxygen Flow Stopped
- Traditional Oxygen Delivery System
Trial Overview
The study tests if an 'on-demand' oxygen delivery system that provides oxygen only when a patient inhales is more effective than traditional continuous-flow systems. The effectiveness will be measured by blood oxygen levels and the accuracy of CO2 monitoring when the flow is stopped during exhalation.
