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

Obstructive Sleep Apnea (Definition)

Sleep apnea has two causes. It may be 'central' or 'obstructive'. Central apnea occurs as a disorder in the way the brain controls breathing. Obstructive sleep apnea is much more common and involves an anatomical blockage of the airway. Usually, the tongue blocks the airway, preventing the passage of air between the a sleep study is needed to diagnose particular ...Read more

Can sleep apnea cause low oxygen level?

Can sleep  apnea  cause  low oxygen  level?

Yes,: Both obstructive and central sleep apnea can lead to a decreased gas exchange in the lung through either decreased airflow or disturbed ventilation during the sleep and subsequently result in low oxygen level in blood. ...Read more

My oxygen starts falling just start to doze off, not asleep. it drops to 89. not sleep apnea becahuse im in light sleep. what does this mean?

My oxygen starts falling just start to doze off, not asleep. it drops to 89. not sleep apnea becahuse im in light sleep.  what does this mean?

Hypoventilation : If you are overweight it can be related to Obesity Hypoventilation syndrome and this goes hand in hand when you have Sleep Apnea. Many Pulmonary diseases can do that too if you have any. Have a clinician see you for definitive answer. ...Read more

Have moderate sleep apnea W/severe O2 loss. Will treat w/CPAP & oxygen. In future is it possible oxygen can be withdrawn & Cpap alone be adequate?

Have moderate sleep apnea W/severe O2 loss. Will treat w/CPAP & oxygen. In future is it possible oxygen can be withdrawn & Cpap alone be adequate?

Sometimes: Depends on whether patients have underlying lung disease and whether oxygen is also needed during the day as well. I have seen those that stay on oxygen and those that end up only on cpap over time. ...Read more

I was just diagnosed w/sleep apnea & was told my oxygen dropped to 68. I know normal levels are in the 90s. What is the effect of levels in the 60s?

I was just diagnosed w/sleep apnea & was told my oxygen dropped to 68. I know normal levels are in the 90s. What is the effect of levels in the 60s?

Sleep apnea: This is a serious condition. Low levels mean that your system esp. Your brain is suffering from periodic deprivation of normal oxidation of the blood, which is dangerous, you should be under care for the apnea, which often is applying pressured air via a face mask to keep oxygen levels normal. ...Read more

Would an oxygen supplement help a 3 y.O. With sleep apnea?

Would an oxygen supplement help a 3 y.O. With sleep apnea?

Usually not: Most likely your 3 y/o has obstructive sleep apnea, which is caused by upper airway obstruction while sleeping. Usually this is from large tonsils and adenoids and can be treated with tonsillectomy and adenoidectomy. Oxygen will not help the airway is blocked. Some children may have other types of sleep apnea or lung conditions that may require oxygen, so you should contact your doctor. ...Read more

I have sleep apnea and a hypoxia index of 17. Is 17 bad or good? I am going on cpap and oxygen. Looking for an answer. Thanks!

I have sleep apnea and a hypoxia index of 17. Is 17 bad or good? I am going on cpap and oxygen. Looking for an answer. Thanks!

Moderately bad: Apnea-hypopnea index of 17 means you obstruct (stop breathing) or partially obstruct an average of 17 times per hour (normal is <5). More important, however, is the degree of oxygen deprivation caused by the disruption. I have many patients who have ahi > 90. If your blood o2 levels are low, your regimen is great. If not low, you can use dental device, likely with good success. ...Read more

If someone has 'hypoxemia' and is receiving oxygen, why would they need to be tested for sleep apnea? Wouldn't the oxygen take care of the apnea?

If someone has 'hypoxemia' and is receiving oxygen, why would they need to be tested for sleep apnea? Wouldn't the oxygen take care of the apnea?

Perhaps.: The hypoxemia may be related to sleep apnea. No, if you have sleep apnea, either the airway is blocked (obstructive) or you don't breath (central). In either case, sleep studies are indicated. ...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

I have pH due to severe central and obstructive sleep apnea. I use an asv machine and oxygen 4l. What other treatment(s) are available?

I have pH due to severe central and obstructive sleep apnea.  I use an asv machine and oxygen 4l.   What other treatment(s) are available?

Heart OK?: Your question seem to suggest at least two things that need to be addressed. Central sleep apnea is usually caused by heart problems. Check with a cardiologist about this matter. The fact that you need additional oxygen suggests that obesity might be a significant modifiable factor. ...Read more

What is the probablity of a person with sleep apnea dying due to lack of oxygen?

What is the probablity of a person with sleep apnea dying due to lack of oxygen?

Sleep apnea: The greater the sleep apnea ( classifications from mild to severe) the greater the chance of dying of " natural causes " in your sleep. Sleep apnea is a serious medical condition and should be actively treated. ...Read more

When I was diagnosed with sleep apnea, the doctor said my blood oxygen level was normal. Do I actually need a cpap?

When I was diagnosed with sleep apnea, the doctor said my blood oxygen level was normal. Do I actually need a cpap?

CPAP: Normal oxygen does not mean that your oxygen saturation did not drop. If you have symptoms of sleep apnea like daytime somnolence, problems concentrating or with memory or irritability or if you have high blood pressure, stroke/tia, coronary artery disease, atrial fibrillation, you have to be treated. Also moderate and severe osa have to be treated, even w/o anything of the above. ...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

Prior ENT exam saw no obstruction relating to sleep apnea. Today diagnosed with/apnea & low oxygen level. Does this mean I have central sleep apnea?

Prior ENT exam saw no obstruction relating to sleep apnea. Today diagnosed with/apnea & low oxygen level. Does this mean I have central sleep apnea?

Sleep Study: A sleep physician will order a sleep study that will clarify your condition. CPAP is the usual initial treatment, but your sleep physician will be the one to decide what course of treatment to follow. Low O2 is a serious condition which requires immediate treatment so don't delay. ...Read more

Home sleep study said moderate sleep apnea w/severe oxygen saturation <70 & in-clinic study said no sleep apnea & perfect oxygen levels. Which right?

Home sleep study said moderate sleep apnea w/severe oxygen saturation <70 &  in-clinic study said no sleep apnea & perfect oxygen levels. Which right?

My reaction: Advise you to sit down with your doctor and go over both studies in full detail, as one of these is clearly WRONG. Although I would favor a clinic outcome due to presence of skilled personnel, I cannot clarify the outcomes from this perspective. Good luck with this. ...Read more

I want to be adding oxygen to cpap for sleep apnea induced asthma attack at night as I have to us my asthma rescue med and have bad sideeffects from?

Review with doc 1st: Although this would seem to be an obvious help, please review your plans with someone who knows your case. Part of what keeps you breathing is the concentration of co2 in your blood and supplemental oxygen under the wrong circumstances could cause problems with your natural breathing drive system. ...Read more

Apnea (Definition)

This is the cessation of breathing for 10 seconds or more. Most apnea is obstructive being caused by collapse or obstruction of the airway leading to lack of air flow. However, it can be a central process, where the respiratory center of the brain fails to signal the respiratory respiratory system to initiate a breath. Lastly, some apnea is mixed central ...Read more
