This study is looking at how accurate pulse oximeters are. These devices measure the oxygen in your blood by shining light through your finger, without needing a blood sample. Researchers will compare pulse oximeter readings to a "gold standard" blood test while participants breathe air with lower oxygen levels (hypoxia). This helps ensure the devices give correct readings for people with different skin tones. You might be able to join if you are a healthy male or female between 18 and 50 years old. The main goal is to measure blood oxygen levels (SpO2) by August 1, 2025. The study status is currently unclear.

Study design

This is an observational study planning to enroll 10,000 healthy participants. It is not specified if it is randomized or blinded.

What's involved

Participants will breathe hypoxic air mixtures to create stable low oxygen levels. This involves having blood samples taken from an arterial line, potentially up to 35 samples, and having pulse oximeter probes placed on various body parts.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint for measuring blood oxygen (SpO2) is set for August 1, 2025. The duration of individual participant follow-up is not specified.
