入选标准
- •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.
排除标准
- •Pregnancy or lactating women
- •Unexplained 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

- •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.
- •Abnormal ECG finding
- •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)
