Rationale:
Ambient light. Other sources of light can cause inaccurate readings. Nail polish. Nail polish on fingernails/toenails can cause inaccurate readings. Inhalation injuries. Clients with inhalation injuries can cause inaccurate readings. Arterial pulses. Venous pulsations, not arterial, can also cause interference. Placement on cartilage. Cartilage will prevent the sensors from interacting, which will produce inaccurate readings.
