Oxygen (Definition)

Oxygen is a gas that the cells in your body need to work properly. The air we breathe normally has 21% oxygen. A maximum of 100% oxygen can be given. Babies with heart or lung problems may need ...Read more

In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?

In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?

Sleep apnea: Sleep apnea is defined as stopping breathing for 10 seconds. During that time, the body is not getting any oxygen. In addition, there can be instances that last less than 10 seconds, or where a less than adequate effort to breath is attempted. These also reduce the oxygen intake. ...Read more

Completed sleep study and have mild sleep apnea. Oxygen recorded during sleep 86%. Will a CPAP machine help ease my high rate of PVCs (20, 000) a day.

Completed sleep study and have mild sleep apnea. Oxygen recorded during sleep 86%. Will a CPAP machine help ease my high rate of PVCs (20, 000) a day.

CPAP and PVCs: Hi Derrick, there is data that demonstrates that CPAP usage does decrease the number of PVCs, but this was only in patients diagnosed with heart failure. Keep in mind that regular CPAP usage should improve any current symptoms related to sleep apnea such as day time fatigue and will also prevent long term complications such as pulmonary hypertension. Hope this helps! ...Read more

Symptoms of oxygen depravation while sleeping?

Symptoms of oxygen depravation while sleeping?

Sleep O2 deprivation: The symptoms vary from mild sleepiness to difficulty concentrating and adhd, anxiety, panic, depression, severe sleepiness, irritability, and mild cognitive deficits to complete disorientation and full delirium that can take days to clear. If it is very severe, a person could die in their sleep. ...Read more

What is oxygen saturation (spo2) while sleeping that is dangerously low?

What is oxygen saturation (spo2) while sleeping that is dangerously low?

It all depends: Without knowing a detailed medical history to determine if "low" oxygen may be a chronic, well compensated issue, it is impossible to answer. Typically normal oxygen staurations are within 94-97% while sleeping. Patients with sleep breathing disorders, like sleep apnea may experience dips in this saturation. However, it is standard to try and keep saturation above 89%. Talk to your doctor. ...Read more

Consistent oxygen saturation of 89-90 while sleeping. Is this considered obstructive sleep apnea?

Consistent oxygen saturation of 89-90 while sleeping. Is this considered obstructive sleep apnea?

Right on the brink: Typically, O2 sats while asleep in a healthy individual should be >90. If yours are typically hitting 90 or below then, I'd say you are right in the crack between barely normal and barely abnormal. I'd think for a 19 year old nonsmoker you could do a bit better than that so it all depends on what else is going on. That number by itself doesn't diagnose OSA but "yes" you could have it. ...Read more

Hi I'm asthmatic its been really bad for past 6weeks I can't lie flat while asleep fel like my airway closes my gp won't help feel like oxygen leveldr?

Hi I'm asthmatic its been really bad for past 6weeks I can't lie flat while asleep fel like my airway closes my gp won't help feel like oxygen leveldr?

Concerning!: You may need to add an inhaled steroid like fluticasone to your asthma therapy in addition to your fast acting inhaler. Be sure to use a spacer (we call them aerochambers here) with your puffs to maximize the lung distribution of your meds. Also you should have a peak flow meter to measure your lung volumes with. You can tailor your medicine to the level of restriction, is the idea. Good Luck ...Read more

Oximeter is giving a reading of 92 with a pulse of 103 for a 3 year old that has asthma while asleep after xopenex (levalbuterol). Is this normal? Is oxygen too low?

Oximeter is giving a reading of 92 with a pulse of 103 for a 3 year old that has asthma while asleep after xopenex (levalbuterol). Is this normal? Is oxygen too low?

See below: A pulse ox of 92% indicates a moderate asthma attack. Pulse is normal. More importantly is wether or not your child is responding to treatment. Proper treatment can prevent the attack from becoming severe with a pulse ox <90%. You want to prevent that. CALL YOUR PEDIATRICIAN FOR ADVICE. If unable to reach he/she have your child evaluated in ER/EC ...Read more

Can a stuffy nose throughout night cause oxygen deprivation? I go to sleep with a little stuff nose and wake up with stuffy nose after 10 hours.

Can a stuffy nose throughout night cause oxygen deprivation? I go to sleep with a little stuff nose and wake up with stuffy nose after 10 hours.

The nose knows: Your stuffy nose, while a nuisance that can cost you a good night's sleep, is no threat to adequate oxygenation. The physiologic drives to maintain adequate oxygen levels will cause you to breathe through your mouth if the nose is obstructed. This is why you wake up with a dry mouth as well as a stuffed nose. ...Read more

My mother has sleep apnea and falls during the day. Her oxygenation drops at night to 60%. Why would they avoid adding oxygen to her cpap & daytime?

My mother has sleep apnea and falls during the day. Her oxygenation drops at night to 60%. Why would they avoid adding oxygen to her cpap & daytime?

Depends on reason: Does her oxygen drop to 60% when she stops breathing, or does it drop to 60% and stay there even when she is breathing normally during sleep? If the desaturation is because of sleep apnea, adding oxygen would not help as air is not going to the lungs. Opening the airway with CPAP allows normal breathing and oxygen values. If it is sustained desaturation, oxygen is usually added. ...Read more
