Performance of Masimo MightySat Pulse Oximeter in Differing Levels of Skin Pigmentation

Performance of Masimo MightySat Pulse Oximeter in Differing Levels of Skin Pigmentation

Evaluation of the noninvasive oxygen saturation (SpO2) performance of the noninvasive Masimo MightySat against reference arterial blood samples analyzed by a laboratory CO-oximeter reference instrument. The study will include different subgroups to assess the performance across different genders and skin pigmentation.

• Subject's blood pressure: Systolic BP ≤ 140 mmHg and ≥ 90 mmHg, Diastolic BP ≤ 90 mmHg and ≥ 50 mmHg, and if systolic BP is lower than 100 mmHg and/or diastolic BP is lower than 60 mmHg, subject passes an orthostatic blood pressure test.
• Subject is able to read and communicate in English and understands the study and the risks involved.

Exclusion Criteria:

• Subject is pregnant.

• Subject has taken opioid pain medication 24 hours before the study.
• Subject has any active signs and/or symptoms of infectious disease (e.g. hepatitis, HIV, tuberculosis, flu, malaria, measles, etc.).*
• Subject is taking medications known to treat any type of infectious disease.
• Subject has either signs or history of peripheral ischemia or carpal tunnel syndrome.
• Subject has had invasive surgery within the past year, including but not limited to major dental surgery, appendectomy, plastic surgery, jaw surgery, major ENT surgery, major abdominal and/or pelvic surgery, heart surgery, or thoracic surgery.*
• Subject has symptoms of congestion, head cold, or other illnesses.
• Subject has been in a severe car accident(s) or a similar type of accident(s) requiring hospitalization within the past 12 months.
