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

What does an apnea/hypopnea index of 1.9 mean?

What does an apnea/hypopnea index of 1.9 mean?

AHI: Apnea hypopnea index is the number of episodes per hour that the breathing either stops or is shallow enough to cause a drop in oxygen saturation and an arousal from sleep. AHI numbers under 5 are fairly normal as most of these episodes are very brief and not remembered by a patient. Most patients with an AHI over 10 will benefit from treatment of sleep apnea.

What is the definition or description of: apnea-hypopnea index?

AHI: Apnea hypopnea index is defined as the number of these events recorded in a psg test per hour of sleep. It is the standard by which a board certified sleep specialist uses in diagnosing the level of obstructive sleep apnea and makes recommendations of treating a particular condition.

Apnea-hypopnea index, how bad an index must one have to have to go on cpap?

How tired are you?: Generally speaking 10 may be the cut off but if you are having excessive daytime fatigue CPAP therapy would be of great benefit for your quality of life.

Arousals: Hard to say. No airway disturbances, just arousals. Reflux disease can irritate and awaken, as can chronic pain symptoms which disturb restful sleep. Fatigue and arousals may be signs of depression or anxiety. Fixes include careful diet and gerd meds, exercise, good sleep hygiene, and management of pain with appropriate meds.

It's a number: Your index is a number that compares # of events per hour on average. Normal people have index of up to 5 per hour. If in range of 5-15, it is mild. Symptoms, however, mandate treatment. Consider all options. Good luck. You can google my (or anyone else's) website for more info.

I have apnea and hypopnea. My doctor told me that the only solution is to put the cpap machine. Is this true?

NO: According to the american academy of sleep medicine guidelines, you should be presented with all your options which includes oral appliances that keep the airway open. Other strategies are; weight loss, changing sleep positions, and surgery.

Sleep study: 154 hypopneas, zero obstructive apneas, 2 central apneas. Could dysautonomia be to blame? (I have Ehlers-Danlos w/POTS & other auto sx.)

Apnea: Your various medical conditions may indeed cause you sleep issues. The sleep doctor should be able to help you do better and, if needed, have you see other medical specialists. Please follow the evaluation and advice of all the doctors you might need to see. Once under better control doctor visits will tone down markedly.

See a Sleep MD: It depends on your actual sleep study. I would have it reviewed with a sleep physician. Sometimes patients with mild apnea and significant daytime symptoms do benefit from cpap. Also, depending on the significance of the leg movements, getting that taken care of will help as well.

Hypopnea: Your breathing does not stop completely while you're sleeping, but you are not getting enough air to keep your blood sufficiently oxygenated. See your sleep physician foe Positive Airway Pressure (PAP) therapy. I hope this helps.

Home O2 monitor consistently records 17-30 hypopnea/hr at night but GP still won't refer as 'looks fine-no apnoea'! Persist y/n? In UK, v. frustrated!

Hypopnea: If you are not happy with the explanation of your GP, find a new one or ask to see a sleep specialist, as 17-20 apnea/hypopnea index is not a normal number to see in the USA for our recordings.

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.

Is apnea during the day a real thing? How is it diagnosed?

Is apnea during the day a real thing? How is it diagnosed?

R/O OSA: OSA can be suggested by history and physical. Excess snoring/daytime sleepiness/apneic episodes/ aM headaches. And the Exam obesity/small oral airway/collar size>18. The definitive test is a PSG with split night/CPAP titration. I would request copy of sleep study and get a second opinion if you are not satisfied with the options. You are young CPAP can be difficult to tolerate. ENT FOR UPP EVAL.

What is the definition or description of: Central apnea?

Central: Centrally mediated (CNS) lack of breathing stimulation. As opposed to obstructive (airway blockage) of air movement. Sleep apnea can be central, obstructive, or mixed.

Central apnea--do I need drug or cpap?

It depends: You may need both or either one depending on how one may benefit you over the other. CPAP can still help central apnea but a bit more tricky. You should have more discussion with a sleep medicine doctor to get a game plan to improve your quality of life.
