This study checks how accurately pulse oximeters (the clips that shine light through your finger or ear) measure blood oxygen when levels drop very low. Twelve healthy volunteers will breathe special gas mixtures to safely lower their oxygen while the device readings are compared…

This study checks how accurately pulse oximeters (devices that measure blood oxygen through the skin) work in healthy adults aged 18 to 50. Participants will have their oxygen levels lowered in a controlled setting while the device readings are compared to actual blood samples. T…

This study is checking whether a Nihon Kohden pulse oximeter accurately measures blood oxygen levels in children with different skin tones. About 180 children, from newborns to 12 years old, who are already in the cardiac intensive care unit with an arterial line will take part. …
