Evaluation of the Melanin-Adjusted Blood Oxygen Sensor (MABOS) in ICU Settings: Improving the Accuracy in Critical Conditions for Patients of Color
Purpose: Investigate the accuracy of the investigators' novel pulse oximeter across a broad range of skin-pigmentations and oxygen saturations. Participants: Up to 120 adult participants admitted to Medical Intensive Care, or Cardiovascular Thoracic Critical Care, Units. Procedures (methods): Participants will have their skin tone measured on each finger using a spectrophotometer. During the study, participants will wear one of the investigators' custom devices - MABOS - on one finger of each hand. Additionally, they will wear a variant of the investigators' device on an additional finger and outer side of the associated wrist. The study team will continuously acquire data from all devices until either 4 Arterial Blood Gas tests have been collected, or 24 hours have elapsed.
• Age ranges from 18 to 85 years.
• Individuals admitted to one of UNC Hospital's intensive care units (Medical Intensive Care Unit or Cardiovascular and Thoracic Intensive Care Unit).
• Individuals with a medical condition necessitating a minimum of two arterial blood gas measurements within a 24-hour period.
• Participant, or Legally Authorized Representative (LAR) must be able to read, write, and speak English fluently.
