You may qualify if…
- Male or female subjects between the ages of 18 to 50 years (inclusive).
- Must undergo a physical examination by a licensed physician, advanced practice nurse or physician assistant, including a 12 lead ECG, a medical history, and a blood test checking complete blood count and screening for sickle cell trait or disease
- All female volunteers must have a negative urine pregnancy test prior to participation.
You may not qualify if…
- A room-air baseline % modulation < 1.5% on all four fingers on the test hand
- Pregnancy or lactating women
- History of syncopal episodes
- Hypertension (defined as a systolic pressure of >145 mmHg or a diastolic pressure >90 mm Hg on three consecutive readings)
- Premature ventricular contractions (PVC's) that are symptomatic or occur at a rate of more than 5/minute
- History of seizures (except childhood febrile seizures) or epilepsy
- Routine use of tranquilizers and/or excessive anxiety
- History of frequent headaches or migraines
- History of stroke
- Previous injury or trauma to fingers or hands that may change blood flow or vascular supply and affect our ability to test multiple sensors
- History of "altitude sickness" defined as headaches, malaise or dizziness when in the mountains or in an aircraft at altitude significantly above sea level for a prolonged period of time (> 1 hour)
- History of significant respiratory disease, such as severe asthma, emphysema, etc.
- Sickle cell disease or trait.
- The use of medications, pre-existing medical conditions, treatment for a medical condition or any other reason deemed relevant by the clinician conducting the study.
- A clinically significant abnormal finding on medical history, physical examination, clinical laboratory test or ECG. Clinical significance will be assessed by the principal investigator or designee.
- Prior or known allergies to lidocaine (or similar pharmacologic agents, e.g., Novocain)
- Prior or known allergies to heparin
- History of transient ischemic attacks or carotid artery disease
- History of myocardial ischemia, angina, myocardial infarction, congestive heart failure or cardiomyopathy
- History of chronic renal impairment
- History of recent arterial cannulation (less than 1 month prior to study)
- History of complications from previous arterial cannulation
- Current use of blood thinners
