Brief Summary

The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with patients at rest.

Conditions

Hypoxia

Outcome Measures

Primary Outcomes (1)

• Accuracy of Sensor Oxygen Saturation by Arms Calculation

  Accuracy will be determined by comparing the noninvasive blood oxygen saturation measurement of the pulse oximeter (SpO2i) to that obtained from a blood sample (SRi) and calculating the arithmetic root mean square (Arms) error value as follows: Arms =Square root (sum of n samples of ((SpO2i - SRi) squared) / n)

  30 seconds

Secondary Outcomes (1)

• Accuracy of Sensor Pulse Rate by Arms Calculation

  30 seconds

Study Arms (1)

Adult healthy subjects

Adult healthy subjects capable of undergoing controlled hypoxemia to the levels outlined in the desaturation profile in an at rest state

Device: Pulse oximeter

Interventions

Pulse oximeter DEVICE

OLV-4202 pulse oximeter (SW version: 01-11)

Adult healthy subjects

Eligibility Criteria

• Age: 18 Years - 50 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Healthy adult volunteers. At least 10 subjects will be recruited to complete the study. Of these 2 will be dark pigmented. If the number of samples is less than the required 200 or if less than 2 of dark pigment subjects successfully complete the study, subjects will be added to include 2 of dark pigmented subjects and at least 200 data points.

You may qualify if:

• Both male and female subjects who can give written informed consent
• Healthy subjects capable of undergoing controlled hypoxemia to the levels outlined in the desaturation profile
• Meeting the demographic requirements

You may not qualify if:

• Age below 18 or over 50
• Pregnant women
• Significant arrhythmia
• Blood pressure above 150 systolic or 90 diastolic
• Carboxyhemoglobin levels over 3%
• Subjects whom the investigator consider ineligible for the study
