    - Anesthesia
    - Cardiopulmonary Care
    - Emergency Services
    - Long-Term Care
    - Nursing
    - Outpatient Care
    - Pediatrics
    - Physician Office

    - This device is not defibrillation proof per IEC 60601-1 clause 8.5.5
  • Warnings:
    This device is intended only as an adjunct in patient assessment
    - It must be used in conjunction with other methods of assessing clinical signs and symptoms
    - The device must be able to measure the pulse properly to obtain an accurate SpO2 measurement
    - Verify that nothing is hindering the pulse measurement before relying on the SpO2 measurement
    - Operation of this device below the minimum amplitude of 0.3% modulation may cause inaccurate results
    - General operation of the device may be affected by the use of an electrosurgical unit (ESU)
    - This device should not be used adjacent to or stacked with other equipment
    - If adjacent or stacked use is necessary, the device should be observed carefully to verify normal operation

My mom has A-Fib where she has fluctuations of heart rate while walking.   Seems like most devices are nor fast enough to capture the fluctuations associated with A-Fib.  Will this device capture the peak heart rate seen with A-Fib patients?
