Even if the pulse oximeter's accuracy is in question at this time,the fact that the patient is exhibiting central and peripheral cyanosis and shortness of breath indicates that there is an oxygenation problem.The presence of peripheral cyanosis indicates that the patient's extremities are in a low perfusion state.Taking a stat arterial blood gas is the only way to fully assess this patient's current oxygenation status.
