Atelectasis: Sometimes, there can be parts of the lung not fully inflated called atelectasis. This could cause low oxygen levels and can be reversed by taking deep breaths. This type of lung exercise can be done using something called an incentive spirometer, and walking around. Hope this helps! ...Read more

What causes low oxygen levels in the elderly?

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

Can Pfo cause low oxygen levels while exercise. My oxygen levels drops down to about 88 while i am walking, then at rest it goes up to 98?

Can Pfo cause low oxygen levels while exercise. My oxygen levels drops down to about 88 while i am walking, then at rest it goes up to 98?

It can: It can but it shouldn't. Talk to your cardiologist. PFO tend to be small and under low pressure so when you exercise it should not effect things as much. Sometimes there is a pressure reversal and this is not a good sign since it can mean weakening of the heart. ...Read more

What are the causes of low oxygen sat rates after surgery?

Interpret right: It depends on the timing. Worst could be pulmonary embolus form immobility several hours after. But right after surgery, usually the or is cold and causes closing off of skin arterioles (response to cold temp) and since the monitor is dependent on pulses could read wrong. The best time to ask is when it is happening as the health officer can correlate with timing and symptoms. ...Read more

If low oxygen levels are causing seizures would the best way to treat them be finding out why oxygen is dropping?

If that is the case?: When you experience a seizure, your oxygen level might dip and your carbon dioxide will also change. Many metabolic changes accompany seizures. I suspect that oxygenation due to seizure activity, not the reverse. You do not list your current anti-seizure meds, but i presume you are taking some medication. Altering your medicines may successfully control the seizures. ...Read more

Please explain what it means if you have low oxygen levels?

Oxygen: The normal o2 in the blood is calculated as that which should be calculated by knowing the lung, the age, water vapor pressure, etc. Very complicated. For our purposes, we set at that oxygen which will give us a saturation of hemoglobin at least 90% in the arteries. If it is lower than that it is low. ...Read more
