SpO2 Validation Study - Philips FAST 2024

To validate the SpO2 accuracy of the SpO2 sensors under test with the Philips FAST Pulse Oximetry technology during non-motion conditions over the range of 70-100% SaO2, when compared with the reference SaO2 obtained from CO-Oximetry analysis of arterial blood samples.

Inclusion criteria

• Participant must have the ability to understand and provide written informed consent
• Participant is adult between 18-50 years of age
• Participant must be willing and able to comply with study procedures and duration
• Participant is a non-smoker or who has not smoked within 2 days prior to the study.

Exclusion criteria

• Participant is considered as being morbidly obese (defined as BMI >39.5)
• Participants with compromised circulation (i.e., Raynaud's Syndrome), injury, or physical malformation of fingers, toes, hands, ears, nose, forehead/skull, or other sensor sites which would limit the ability to test sites needed for the study. Tattoo (e.g. permanent, Henna) or artificial dyes (including spray tan, pigmented tanning lotion) in the optical path which would limit the ability to test sites needed for the study. (Note: Certain malformations may still allow participants to participate if the condition is noted and would not affect the particular sites utilized.)
• Females who are pregnant, who are trying to get pregnant, (confirmed by positive urine pregnancy test unless the participant is known to be not of child-bearing potential)

• history of blood clots,
• hemophilia,
• current use of blood thinner: prescription or daily use of aspirin,
• Sickle Cell Trait or Disease
• Participants with self-reported dermatological conditions at sensor application sites
• Severe dermatitis,
• Hyperkeratosis,
• Nail fungus
• Participants with severe contact allergies to standard adhesives, latex, silicone or other materials found in pulse oximetry sensors, ECG electrodes, respiration monitor electrodes or other medical sensors (self-reported)
• Participants with severe allergies to iodine (only applicable if iodine is used)
• Participants with severe allergies to lidocaine (or similar pharmacological agents, e.g. Novocaine),
