• failure to cover the O
material in high ambient light conditions
• venous pulsation
• dysfunctional hemoglobin
• low perfusion
Loss-of-pulse signal can occur for the following reasons:
• the O
• defibrillation
• a blood pressure cuff is inflated on the same
extremity as the one with the O
attached
• there is arterial occlusion proximal to the O
sensor
• poor peripheral perfusion
• loss of pulse/cardiac arrest
High ambient light sources that can interfere with the
performance of an SpO
• surgical lights (especially those with a xenon light
source)
• bilirubin lamps
• fluorescent lights
• infrared heating lamps
• direct sunlight
