The information provided on this site is not intended nor recommended Whereas OSA is extremely common in the adult population, central sleep apnea (CSA) affects less than 10% of patients referred to sleep laboratories. -- [http://doctorstevenpark.com/dr-barry-krakows-review-of-totally-cpap-part-5]. I believe that many patients never need to make any adjustments whatsoever to their machines. I track my events, usage, seal and total score daily on Myair which is a Resmed product. . I slept for 6:48 with 100 percent mask fit. From the low single digits (3 – 4.5) to sometimes north of 10. Feeling claustrophobic. The objective data (leak rate and event indexes) along with subjective judgements on how you feel is a powerful combination for getting treatment as good as it can be. Most recently it has been trending to 13.8. Please be advised that these posts may contain sensitive material or I just assume phlegm and such get into my throat and cause breathing problems. First, just hold it up to … I have turned off the the BiPap to experiment and run at 25 and not seen any difference in AHI or air leaks, etc. I also noticed that my "events" per hour had increased and were up to 11.5 per hour. I looked the factory set and my top pressure is 16m which I think is adequate to control most Apneas. I contacted my health care provider and they had the pressure reduced to 10 max. 2. I perfectly understand how the poster feels. When I get a cold, my AHI numbers shoot up quite considerably.

That is an AHI of 6.9 (I'm too tired to double check) which is only slightly elevated. When I saw the new ResMed Airfit F20 I knew that I had to try it. This potentially could wreak havoc on the machine’s algorithms which try and make the airflow comfortable by making small adjustments rather than massive increases in titration when you start having events. My numbers last night were Total clear away Apneas 28 I don't have data on how many are OSAs. If your machine increased pressure from the lower to the higher, that is because it detected one of two things. This number can help measure how well your treatment is working. Hypopnea is a partial blockage of airflow resulting in arousal and a possible drop in oxygen level. The pressure setting is a fairly serious matter and incorrect can either not provide effective therapy or actually be dangerous. Small movements, slowly, over time, for treatment pressures can be fine--but only when AHI trends down in average from doing so and a close eye is kept on it. My usage hours have ranged from 7-9 hours per night. The great thing about the ResMed S10 Autoset machine is that a low and high limit can be set for auto titration. There is no reason why patients could not be instructed in this approach to care . “Sleep events per hour” refers to a simple way to measure the severity of sleep apnea or hypopnea. This number means I had an average of 48 sleep interruption "events" per hour -- these events range from blood-oxygen desaturation to a complete closure of the airway. Learn what your goal AHI should be to maximize the benefits of using CPAP for optimal therapy and how the pressures are determined and should be adjusted. To count in the index apneas and hypopneas, collectively called events, must have a duration of at least 10 seconds. Apnea: An apnea is any pause in breathing lasting longer than 10 seconds and is often caused by loose tissues in the throat and sinuses. Most nights my number of events per hour is between 3 and 6.

Either way, I’m not too concerned about it because like I said, I feel so much better now that my odd AHI scores are just a curiosity piece for me more than anything else. I strongly support the idea that you consult with you doctor, but it should not be hard to have a try at turning you CPAP up a little to see if this reduces your residual AHI without negatively affecting you comfort. After continuing sleep with CPAP machine by morning improved on some scale of normal breathing of 1 to 26 apneas per hour - I scored a 24. Getting used to CPAP therapy takes time. Total Hypopneas 3 I believe those are the patients Park and Krakow refer to. Events Per Hour (AHI) This factor has a maximum of 10 points and is calculated by the number of apneas and hypopneas per hour. Heck, while you are talking with the sleep doc, as that doctor how/why making changes on the fly would be of benefit. For the second time though in the last month I’ve had a really strange anomaly – my AHI score jumped up to over 13. The obstructive apneas may be helped by pressure adjustments, BUT those clear-airway apneas could be central apneas, which can be made *worse *by pressure adjustments. (In other words, why is my CPAP machine showing an AHI – apneas and hypopneas I have per hour– more than zero?) My AHI is usually around 0–1. .

PSG shows more than 15 scorable respiratory events (eg, apneas, hypopneas, RERAs) per hour of sleep and/or evidence of respiratory effort during all or a portion of each respiratory event.

After being diagnosed with severe APNEA, I was given a ResMed9, Autopap, and my numbers stayed for about a year in the 1.7 to 3.9 or even 4.0 range. I appreciate that some patients cannot learn to approach their care in this manner, but arguably anywhere from 30 to 60% of PAP users could learn this approach, and it’s just common sense that healthcare systems should be implemented to encourage patients to understand how to gather subjective data about themselves to then make informed decisions about changing the objective pressure settings on their machines." Total obstructive Apneas 16 Perhaps they are the majority. I have the humidity set to automatic (adjusts based on the room humidity).

These users will continue to experience the negative effects of sleep apnea, including poor sleep, waking up gasping for air, feeling air-starved, chronic fatigue, high blood pressure, and others. These events are classified as Apneas or Hypopneas. . Without knowing the numbers, I just get on with it and check when I get home from work.

Another current sleep disorder, medical or neurologic disorder, medication use, or substance use does not better account for the patient’s condition. When I first went got my CPAP machine I would worry about the results every single day, hoping that my “numbers were good”. I had sixty events per hour. Any comments? The setting of 9 was arrived at after a study to determine optimum pressure and prescribed by a doctor.
