    5. unresolved respiratory or lung surgery
    6. emphysema, COPD, lung disease
    7. recent COVID (last 2 months)
  8. Participants with known heart or cardiovascular conditions such as:

    1. Uncontrolled hypertension (systolic pressure >140mmHg, or diastolic pressure >90mmHg on 3 consecutive readings day of screening)
    2. previous cardiovascular surgery

Design Details

Cohorts and Interventions

Group / Cohort
Healthy Volunteers
All subjects who meet the inclusion criteria and none of the exclusion criteria will be enrolled into the test group and will participate in data collection with use of the Nellcor™ Pulse Oximetry device with each of the market-released Nellcor™ Pulse Oximetry test sensors.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluation of pulse rate accuracy
Time Frame: 2 - 3 hours
Performance will be determined by calculating the accuracy in terms of root mean square difference (ARMS) comparing the pulse rate measurement from the Nellcor Pulse Oximetry device to the heart rate measurements as obtained by ECG.
2 - 3 hours
Evaluation of saturation accuracy
Time Frame: 2-3 Months
Performance will be determined by calculating the accuracy in terms of root mean square difference (ARMS) comparing the noninvasive oxygen saturation measurement (SpO2) to the arterial oxygen saturation (SaO2) value obtained from a reference blood sample.
2-3 Months
