What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new sensor, the RD SET Sensor, to assess its accuracy in measuring oxygen levels across different skin tones. It focuses on individuals in intensive care with low oxygen levels, who may require supplemental oxygen or have difficulty obtaining sufficient oxygen naturally. Eligible participants must be in an intensive care unit, have an arterial catheter (a small tube) in place, and experience low oxygen levels. As an unphased trial, this study provides a unique opportunity to contribute to research that could enhance oxygen monitoring for diverse populations.

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What prior data suggests that the RD SET Sensor is safe for use in measuring low oxygen levels?

Research has shown that Masimo RD SET® sensors are generally safe and reliable for checking blood oxygen levels. Studies have found that these sensors work accurately for people with different skin tones, even in challenging situations like movement or low blood flow. This accuracy is crucial in medical settings where exact readings are essential.

The sensors use advanced technology to reduce false alarms, resulting in fewer unnecessary interruptions for patients. Available data has not reported any specific negative effects from using these sensors. Their widespread use in hospitals suggests they are well-tolerated by patients. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The RD SET Sensor is unique because it offers a non-invasive way to measure blood oxygen levels, which is crucial for patients with conditions leading to low oxygen levels in the blood. Researchers are excited about this sensor because it utilizes advanced technology to provide more accurate and reliable SpO2 readings compared to traditional pulse oximeters. This could lead to better monitoring and management of patients with respiratory conditions, ensuring timely interventions and potentially improving outcomes.

What evidence suggests that the RD SET Sensor is effective for measuring low oxygen levels?

No edits are necessary because this trial includes only one treatment arm. ^{3 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults over 18 in intensive care with low oxygen levels, who have an arterial catheter. It's not for those with unreliable pulse oximetry on certain fingers, skin pigmentation conditions like vitiligo, nail polish/acrylics where the sensor goes, allergies to adhesive tapes, lower extremity arterial catheters or specific skin conditions on their digits.

Inclusion Criteria

Subject with an arterial catheter in place

Subject is receiving care in an intensive care unit

I need extra oxygen or my oxygen levels are 94% or less without it.

Exclusion Criteria

Subjects in whom pulse oximetry cannot be reliably performed on both the third and fourth digit on the hand ipsilateral to the arterial line, precluding application of the sensor (e.g., amputation and deformity)

Subjects with distinct geographic variances in skin pigmentation (e.g., vitiligo) on the digit where the sensor is applied, which would preclude sensor placement as standard of care

Subjects with nail polish or acrylic nails on the digits where sensor needs to be applied
