About

To collect data on a variety of market approved Nellcor™ pulse oximetry sensors with the Nellcor™ Pulse Oximetry device to support the market approval.

Full description

The purpose of this study is to collect data on the Nellcor™ Pulse Oximetry device when paired with a variety of Nellcor™ Market Released sensors under invasive, controlled desaturation conditions, to verify Pulse Rate and SpO2 accuracy in a diverse participant population over a specified saturation range.

Enrollment: 55 estimated patients

Sex: All

Ages: 18 to 51 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Male or female participants ≥ 18 years of age, and < 51 years of age.

Exclusion criteria

1. Participant is considered as being morbidly obese (defined as BMI >39.5).

2. Compromised circulation, injury, or physical malformation of fingers, hands, ears or forehead/skull or other sensor sites which would limit the ability to test sites needed for the study. (Note: Certain malformations may still allow participants to participate if the condition is noted and would not affect the sites utilized)
