It is classified into 4 groups: - hypoxemic - oxygen is low - anemic - decreased ability for hemoglobin to carry oxygen. - ischemic - decreased blood flow. - histotoxic - oxygen is reaching the cells, but the cells are unable to use ...Read more

What causes low oxygen levels in the elderly?

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. ...Read more

What does it mean if you have low oxygen levels in your blood tests?

What does it mean if you have low oxygen levels in your blood tests?

Lung disease: Is the commonest reason for a low level of oxygen in the blood. It can also happen in heart disease if the heart is failing and fluid builds up in otherwise-healthy lungs, or if there is a hole in the heart, causing blood to bypass the right heart circulation into the lungs and skip picking up oxygen there. These are examples of some common causes. Smoking, high altitude=examples of lung reasons. ...Read more

Is it normal for healthy person to have low oxygen on flight? Dipped down to 91-89 on my last flight and had a headache. Worried about undiagnosed PE.

Is it normal for healthy person to have low oxygen on flight? Dipped down to 91-89 on my last flight and had a headache. Worried about undiagnosed PE.

Stop: Why are you checking your oxygen on a flight? If it constantly stays below 89 for more than 5 min AND you feel short of breath, have chest pain, or pain and swelling in your legs then start to worry and see a doctor. Portable pulse oximeter readings bounce around all the time- it is usually from motion artifact and not a true reading. Try browsing the in-flight magazine to pass the time... ...Read more

Causes for low oxygen sats93-97%?

Many possibilities: With a proper medical history one might make some good guesses. That along with a proper physical exam might help better explain. Blood work could possibly even help. Not uncommonly it is a combo of things age included. Generally, it is not a major issue as long as it remains above 90, but still if there has been a sudden change it warrants looking into further. ...Read more
