In brief: Other diseases

If you ask me what causes low o2 in a perfectly normal and healthy elderly it makes a difference.
There is an alveolar to arterial ratio that changes with age, and o2 is lower in elderly by this notion alone but no to point of hypoxia. There is such thing as senile emphysema by age alone, with the changes like that of the skin. See the compressibility of finger as the machine could restrict pulse.

Pneumonia. Sepsis from any other infection heart failure bronchitis and atelectasis. Needs evaluation.
