NCT06850610

Brief Summary

This study tests the accuracy of pulse oximeters in a range of arterial oxygen levels from 100% down to 70%. This is done by comparing the test pulse oximeter readings of young, healthy, adult study participants with blood samples drawn from an artery in the wrist during brief plateaus of progressively lower oxygen saturations. The arterial blood sample is processed in a device called a multi-wavelength hemoximeter and compared to the simultaneous oximeter reading. During each set level of oxygen the participant may be asked to have a motion simulator device apply different types of movement to their hands to assess the pulse oximeter's accuracy during motion. This study will be evaluating the Owlet OSS 3.0 sensor, a component in 2 FDA cleared noninvasive pulse oximeters indicated for infants 1-18 months of age. Testing should require approximately an hour and 15 minutes of the participant's time.

Outcome Measures

Primary Outcomes (1)

  • Pulse Oximeter Accuracy Measures

    * Overall Accuracy: Arms is less than 3%. * Non-Disparate Performance Evaluation 1: Among pairwise comparisons of MST groups 1-4, 5-7, and 8-10, the largest difference in SpO2 bias is less than 3.5% for the interval 70% ≤ SaO2≤ 85% and less than 1.5% for 85%\< SaO2 ≤ 100%. * Non-Disparate Performance Evaluation 2: For a 100-point change in emitter sensor site ITA, the difference in SpO2 bias is less than 3.5% for 70% ≤ SaO2≤ 85% and less than 1.5% for 85%\< SaO2 ≤ 100%

    From enrollment to completion of 6 plateaus of hypoxia over an approximate 75 minute period.

Study Arms (1)

Hypoxia Plateau Protocol

EXPERIMENTAL

Study participants that all undergo standardized plateaus of oxygen desaturation to evaluate the accuracy of the Owlet noninvasive pulse oximeter during motion and nonmotion conditions.

Diagnostic Test: Pulse oximeter accuracy under hypoxic conditions

Interventions

This study will specifically evaluate the accuracy of the Owlet pulse oximeter sensor, currently FDA cleared for infants 1-18 months of age in an expanded hypoxia lab trial.

Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • The subject is in good general health with no evidence of any medical problems.
  • The subject is fluent in both written and spoken English.
  • The subject has provided informed consent and is willing to comply with the study procedures.

You may not qualify if:

  • The subject is obese (BMI\>35).
  • The subject has a known history of heart disease, lung disease, kidney or liver disease.
  • Diagnosis of asthma, sleep apnea, or use of CPAP.
  • The subject has diabetes.
  • The subject has a clotting disorder.
  • The subject has a hemoglobinopathy or history of anemia, per subject report or the first blood sample, that in the opinion of the investigator, would make them unsuitable for study participation.
  • The subject has any other serious systemic illness.
  • The subject has a carboxyhemoglobin level greater than 3% (determined during the first sample)
  • Any injury, deformity, or abnormality at the sensor sites that, in the opinion of the investigators' would interfere with the sensors working correctly.
  • The subject has a history of fainting or vasovagal response.
  • The subject has a history of sensitivity to local anesthesia.
  • The subject has a diagnosis of Raynaud's disease.
  • The subject has unacceptable collateral circulation based on exam by the investigator (Allen's test).
  • The subject is pregnant, lactating or trying to get pregnant.
  • The subject is unable or unwilling to provide informed consent, or is unable or unwilling to comply with study procedures.
  • +1 more criteria
