Final answer:
The recommended arterial oxyhemoglobin saturation value for a patient with return of spontaneous circulation is within the normal pulse oximeter reading range of 95-100 percent to prevent hypoxemia and hypoxia.
Step-by-step explanation:
When titrating inspired oxygen for a patient who achieves return of spontaneous circulation, the recommended arterial oxyhemoglobin saturation value lies within a normal range. Normal pulse oximeter readings are between 95-100 percent, indicating adequate levels of oxygen in the blood. This value is crucial for ensuring that the tissues, especially sensitive areas like the brain, receive sufficient oxygen to function properly after an event such as cardiac arrest. Maintaining arterial oxyhemoglobin saturation levels in this range helps prevent conditions like hypoxemia (low blood oxygen) and hypoxia (low oxygen levels in tissues), both of which can lead to serious complications.
