Hi,

Welcome to icliniq.com.

I can understand your concern.

According to your investigation reports (attachment removed to protect the identity of the patient), the mean oxygen saturation (SpO2) is 97.2 percent; normal SpO2 is usually 95 percent. Some patients with chronic lung disease or sleep apnea can have normal levels of around 90 percent. According to the reports, there may be some changes in oxygen saturation with the passing of time, but as a whole, the mean SpO₂ is 97.2 percent, which is good.

So, I think you do not need to be worried at all. It is also important to correlate the presenting signs and symptoms of the patient with the investigation reports. SpO2 drops can be said to occur when the oxygen saturation level is below 90 percent, with associated signs and symptoms.

I hope this helps.

Please feel free to reach out in case of further queries.

Thank you.

Patient's Query

Hello doctor,

Thank you for your reply.

She always has symptoms at night. She experiences severe moodiness and feels tired shortly after waking up. She is very irritable, and her oxygen saturation (SpO2) levels are dropping.

Please help.

Thank you.

Hi,

Welcome back to icliniq.com.

It is normal for oxygen saturation levels to fluctuate with an activity if her oxygen saturation level runs low on an ongoing basis, whether at rest, during activity, or while sleeping. Talk to her pulmonologist or doctor about using supplemental oxygen. At first, when you think that your daughter's oxygen saturation rate is below normal, you can determine this by watching her clinical features.

Then you should monitor her oxygen saturation rate at once by using a pulse oximeter. If you find that her oxygen saturation level is below 92 percent, you should arrange oxygen therapy for her in the hospital or at home. A drop in oxygen saturation is referred to as desaturation or hypoxemia, resulting from underlying health conditions like asthma, COPD (chronic obstructive pulmonary disease), or other respiratory diseases, heart diseases, anemia, carbon monoxide poisoning, high altitude, and many more.

A decreased oxygen saturation level may cause a bluish hue to appear on the nose, lips, tongue, the skin of different areas of the body, etc. That is cyanosis and fatigue, exertional dyspnea, irritability, mood swings, etc. The oxygen saturation level is below 92 percent, as indicated by the pulse oximeter, which indicates supplemental oxygen therapy. After arranging oxygen therapy, some investigations should be done to find out the exact underlying causes for her present sufferings or fluctuations of oxygen saturation, and then treat them accordingly.

I hope this helps.

Thank you.
