What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if a motion sensor placed on the chest can accurately track the amount of air a person breathes in. Researchers seek to compare the sensor's effectiveness with that of an incentive spirometer, a device used post-surgery to aid breathing. Healthy adults are invited to join this trial, particularly those interested in advancing methods for monitoring breathing after surgery. Participants will attend a short clinic visit to test the sensor's ability to measure breathing. As an unphased trial, this study allows participants to contribute to innovative research that could enhance post-surgical care.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators.

What prior data suggests that this motion sensor is safe for monitoring breathing?

Research shows that the motion sensors used in this trial safely monitor breathing. Worn on the body, these sensors do not require invasive procedures. Studies on similar wearable sensors have found that they effectively track breathing without causing discomfort or harm. The technology is well-tolerated, as it detects chest movement to measure breathing patterns. No significant reports of problems have emerged from using these sensors. Since this trial involves healthy volunteers and uses a noninvasive method, the risk of harm remains low. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using noninvasive motion sensors for monitoring breathing because these sensors offer a unique way to track respiratory patterns without any physical contact. Unlike traditional methods such as spirometry or wearable devices that require direct contact with the body, these sensors can detect breathing movements remotely, making them more comfortable and convenient for users. This technology holds promise for continuous, real-time monitoring, which could revolutionize how we track respiratory health in a variety of settings, from hospitals to home care.

What evidence suggests that this motion sensor is effective for monitoring breathing?

Research has shown that noninvasive motion sensors, which participants in this trial will use, can effectively track breathing by monitoring chest movements. One study found that these sensors' readings matched those from a commercial device used to measure breathing effort. Wearable sensors have shown promise in healthcare by identifying breathing patterns and some signs of respiratory issues. By observing chest movements, these sensors can help measure the amount of air a person breathes in. This technology offers a new way to monitor breathing without invasive methods. ^{1 4 6 7 8}
