Decreasing spo2 signifies - decreased efficiency of lungs to absorb enough oxygen, required to have normal gaseous exchange.

SPO2 or pulse oximetry
It is about 70 to 75 for a full term healthy newborn during the first 1-7 days
after fasting all night, what's the normal blood sugar level in the morning
Pulse 120 to 150, SpO2 97% (SpO2= saturation derived from a pulse oximeter, a 2 wavelength, red and infrared, non-invasive probe). The heartrate will change as the infant ages, slowing down, while the oxygen level should remain constant throughout adulthood. An SpO2 of 97% is technically as high as it can go on room air, as there is a normal 3% anatomical shunt. This can however be increased if there is exposure to CoHb (Carbon Monoxide) which has an affinity for the heme ring of the red blood cell 210-240 times that of oxygen. Pulse oximetry has limitations and cannot differentiate between oxyhemoglobin and carboxyhemoglobin. That requires photospectronomy.
Since the normal SpO2 max is ~98%, due to physiological demands/metabolism, it would be the accuracy of the equipment that produced a 100% reading. Typically, pulse oximitry has an accuracy of +/- 2%.
Possibly sleep apnea.
Depends how it is measured, and whether oxygen therapy is being given. The two main methods for measuring oxygen in the blood are oxygen saturation (often referred to as sats, or SpO2) and from an arterial blood gas (PaO2)SpO2 on air should be >98%, it decreases when you have a cold, if you smoke etcPaO2 on air should be 12-14.5 kPaIf oxygen therapy is being given then these values should be higher
