Pulse oximetry is a noninvasive measure of oxygen saturation of hemoglobin.Capnography measures carbon dioxide inhalation and exhalation.It does not provide information about oxygen saturation.Arterial blood gases provide additional clinical information,including pH,PCO_2,bicarbonate,base excess,and PO₂.An arterial puncture is required,which can be painful,and continuous monitoring cannot be done without an arterial line.Pulse oximetry can be either intermittent or continuous.
