* Subject has donated blood within the past 4 weeks.
* Subject has Wolff-Parkinson-White Syndrome or Stokes-Adams Syndrome.
* Subject has any symptomatic cardiac dysrhythmia (e.g. atrial fibrillation) and has not received clearance from their physician to participate.
* Subject has a known neurological and/or psychiatric disorder (e.g. schizophrenia, bipolar disorder, multiple sclerosis, Huntington's disease) that interferes with the subject's level of consciousness.\*
* Subject has taken opioid pain medication 24 hours before the study.
* Subject has any active signs and/or symptoms of infectious disease (e.g. hepatitis, HIV, tuberculosis, flu, malaria, measles, etc.).\*
* Subject is taking medications known to treat any type of infectious disease.
* Subject has either signs or history of peripheral ischemia or carpal tunnel syndrome.
* Subject has had invasive surgery within the past year, including but not limited to major dental surgery, appendectomy, plastic surgery, jaw surgery, major ENT surgery, major abdominal and/or pelvic surgery, heart surgery, or thoracic surgery.\*
* Subject has symptoms of congestion, head cold, or other illnesses.
* Subject has been in a severe car accident(s) or a similar type of accident(s) requiring hospitalization within the past 12 months.
* Subject has any cancer or history of cancer (not including skin cancer).\*
* Subject has chronic unresolved asthma, lung disease (including COPD) and/or respiratory disease.
* Subject is allergic to lidocaine, chlorhexidine, latex, adhesives, or plastic.
* Subject has a heart condition, insulin-dependent diabetes, or uncontrolled hypertension.
* Subject has delivered vaginally, has had a pregnancy terminated, a miscarriage with hospitalization, or had a C-section within the past 6 months.
* Subject intends on participating in any heavy lifting, repetitive movement of their wrist (including riding a motorcycle, tennis), exercise (working out, riding a bike, riding a skateboard, etc.), or any activity that will put additional stress on the wrist within 24 hours following a study that involves an arterial line.
* Subject has any medical condition which in the judgment of the investigator and/or medical staff, renders them ineligible for participation in this study or subject is deemed ineligible by the discretion of the investigator/study staff.
