This is an interesting study where 34 babies were given reduced oxygen for an average of 6.9 hours by only giving them 15% oxygen in the air they breathe rather than the normal 20%.
In 4 infants exposure to hypoxic conditions was ended early because of prolonged and severe falls in oxygen saturation.
Now this is what is called a "non-theraputic" intervention. That is something is done to the babies which is not to improve their health. That something is to reduce the amount of oxygen they breathe.
This sounds a very odd thing for anyone to agree to for their 3 month old child.
In particular (see above italics) it caused material problems for about 10% of the babies.

Comments
It did not test for these circumstances.
The questions remains, however, as to whether or not the research is ethical.
That is one reason why the particular experiment did not compare to the change when going to high altitude (or in a plane).
