CPAP Machine and Sinus Infection
CPAP Machine and Sinus Infection

The most effective treatment for OSA is continuous positive airway pressure therapy. Those with OSA can’t live without CPAP, but the therapy isn’t always adhered to because of common adverse effects like dry eyes, face discomfort, and headaches. One prevalent worry with CPAP machines is the risk of sinus infections, especially for people who suffer from seasonal or chronic allergies.

Fortunately, we did not find that CPAP machine therapy actually increased the risk for sinus infections so long as you maintained a regular cleaning regimen. The best defense against a sinus infection caused by CPAP is regular maintenance, including changing or cleaning the air filter (depending on whether your machine utilizes reusable or disposable filters), rinsing and disinfecting the CPAP hose, and emptying the humidifier chamber.

Keep reading and we’ll explain everything you need to know about CPAP machine-caused sinus infections and how to avoid getting them in the first place, including what causes them and what you can do about it.

Does Using a CPAP machine Cause Sinus Infection?

Without further humidification, CPAP therapy naturally dries the airway and forces filtered air from the surrounding environment into the lungs. A CPAP machine that is not regularly cleaned can become a breeding ground for bacteria, although the therapy itself is not linked to an increased risk of sinus infections.

Two studies, one from 2012 and another from 2016, support the idea that OSA patients frequently have nasal inflammation and sinus infections. Those with OSA were found to be 3.18 times more likely than those without OSA to develop chronic rhinosinusitis.

However, the data also revealed that CPAP users had increased resistance to bacterial invasion of their disease-fighting white blood cells. Because this tolerance was not observed in non-CPAP therapy patients, we can infer that CPAP therapy reduces the risk of sinus infections rather than exacerbates existing ones.

Further, a 2017 study found that CPAP users did not have more sinus infections than non-CPAP users. It also discovered that the mask, machine, and humidifier you use make no appreciable difference in the frequency with which you have sinus infections.

Poor maintenance and improper usage of a CPAP machine can lead to airway irritation and sinus infections, but the equipment itself does not cause these conditions. As a result, using CPAP while neglecting to keep the device clean is the only way to get a sinus infection.

In addition, if the device’s tubing or mask isn’t cleaned regularly, bacteria and other germs can begin to multiply there. Mold and fungi can grow in the humidifier, increasing the likelihood of a CPAP-related sinus infection.

Preventing Sinus Infections While Using CPAP Machine

The best way to avoid CPAP sinus problems is to maintain your CPAP machine regularly. The following is a list of things you can do to reduce your risk of developing a sinus infection due to using a CPAP machine:

Always change the air filters and clean your CPAP machine.

The importance of keeping CPAP equipment clean cannot be overstated, especially if you suffer from seasonal or chronic allergy issues. Your CPAP mask and cushion/nasal cushions should be washed daily in warm water with mild soap as soon as you get out of bed. 

The humidifier tank needs to be emptied and dried, and the line needs to be hung up to air dry. Humidifier tanks and hoses should be washed out with soap and water once a week.

If your machine has a disposable air filter, you should change it at least once a month to keep it functioning properly. A reusable filter in your machine should be cleaned once a week and swapped once every six months.

The danger of illness from fungi, mildew, and bacteria can be reduced by using a specialized CPAP cleaner, which should be used in addition to, rather than in place of, your regular cleaning routine. 

Use Distilled Water

To avoid unpleasant side effects like a dry mouth, stuffy nose, or nosebleeds, heated humidification is essential. While some microorganisms, like yeast and mold, flourish in warm and damp conditions, it is …

Guide on How to Set Up Your CPAP Pressure Correctly
Guide on How to Set Up Your CPAP Pressure Correctly

In order to give the most recent valid information, Air Liquide Healthcare routinely compares the information included within our pages to that found in the most recent scientific publications and most highly recommended websites, and other resources.

Those who suffer from obstructive sleep apnea (OSA) have difficulty breathing for brief periods while they sleep as a result of their airways being obstructed or collapsing. After a sleep apnea test, doctors will often recommend using a CPAP Mask to treat the issue. The gadgets assist normalise breathing by delivering pressured air. Too little or too much pressure can have unfavorable consequences on CPAP therapy, so getting it just right is essential.

We’ll go over the several variables that go into establishing a comfortable CPAP pressure level. We’ll point out warning indicators that should prompt you to visit your doctor and request a blood pressure adjustment. Only a medical specialist should adjust the pressure settings.

Adjusting Your CPAP’s Pressure

A CPAP Machine’s output pressure is expressed in centimeters of water pressure (cm H2O). Device-specific, the typical pressure range for CPAP devices is between 4 and 20 cm H2O. Though uncommon, there are devices that can pump up to 30 cm H2O. People with OSA typically have a pressure setting1 of around 10 cm H2O.

The most typical approach to settling on a suitable pressure out from your CPAP mask is a titration study. The evaluation takes place over the course of one night, just like a sleep study would. Your oxygen levels, respiration, heart rate, brain waves, and mobility are all tracked by sensors that are strapped to your person. A doctor or sleep expert will adjust the CPAP pressure until the minimum level necessary to maintain open airways is reached.

The number of times a person stops breathing or breathes shallowly when asleep is measured by the apnea-hypopnea index (AHI), which is used to guide the adjustment of CPAP pressure by doctors. The AHI is tracked by most current CPAP devices, so you and your doctor can easily see whether your pressure needs to be adjusted.

Essential to the success of your therapy, you will be equipped for a CPAP mask during the trial. Full-face masks, nasal masks, and nasal pillows are just some of the CPAP mask options out now. After the research is complete, you and your doctor may talk about the best CPAP pressure setting for you. Depending on the findings, they may also suggest adjustments to your CPAP routine.

Adjusting the Pressure on a CPAP Mask: Some Considerations

The severity of OSA and the required CPAP pressure for an individual depend on a number of factors. Some are inherent to the human body, while others are the result of behaviours like eating late at night or not getting enough shut-eye.

People with craniofacial or upper airway anomalies, such as a tiny lower jaw, a big tongue or tonsils, or a neck circumference of more than 17 inches, may be more susceptible to developing OSA and may require higher CPAP pressure settings. Click here to read about CPAP pressure and flow data at 2 positive pressure levels and multiple controlled breathing rates from a trial of 30 adults.

A deviated septum restricts nasal airflow, which may need a greater amount of pressure to maintain an open airway in the head and neck.

Extra tissue in the neck of obese persons is associated with decreased airflow to the lungs, hence BMI is an important factor to consider. When a person loses a large amount of weight, they often need to reduce their pressure setting because pressure needs tend to grow with a person’s weight.

Nasal allergies: Allergies and nasal congestion may impede breathing, leading to lower oxygen levels. A CPAP Mask equipped with a humidifier may be useful for those with allergies, in addition to the pressure settings calibration. Filters may also be kept free of allergens by being cleaned regularly.

Sleeping on one’s back is thought to be the worst posture for sleep apnea6 because the body’s weight presses down on the trachea and esophagus. As a result, those …

What Does a High CPAP AHI Mean?
What Does a High CPAP AHI Mean?

Users of continuous positive airway pressure (CPAP) devices and apps often report feeling confused by the data they are presented with. The AHI is one such, if not the most significant measures that your CPAP machine records. In this article, we’ll discuss how to evaluate your AHI and what steps you may take to bring it down if necessary.

In CPAP terms, what does an AHI mean?

Apnea-hypopnea index is the abbreviation for this measurement. Sleep studies are the gold standard for estimating AHI. The word REI (respiratory event index) may be used instead of AHI in a home sleep apnea test result.

In CPAP terms, what does an AHI mean?

When you remove your CPAP mask in the morning, many devices may display information about your use the night before, including your AHI. To differentiate this value from the AHI that is determined by the gold standard, a sleep study, I prefer to call it the “calculated AHI” or cAHI.

With the use of a CPAP machine’s smartphone app, you may collect and analyze more data over time. You need to connect your CPAP machines to a clinical database in order to get the full range of available information. The AHI is broken down into snoring, central apneas, obstructive apneas, and hypopneas, which I, as a sleep physician, can access.

CPAP: what’s a decent AHI?

In most cases, the cAHI should be set at or below 5, as this value indicates the absence of sleep apnea as determined by a sleep study. From what I’ve seen, a cAHI of 5 or less is considered good, but a cAHI of 3 or less indicates that your sleep apnea is under excellent control. Please be aware that I have never encountered a zero AHI. No matter how well you program your system, it will always estimate a small number of breathing occurrences as a residual.

“Treat the patient, not the numbers” is a common medical maxim. Nighttime oxygen level studies are frequently checked if an AHI is high despite the patient’s report of good sleep and general well-being during the day. I will not adjust the CPAP settings if oxygen levels are within normal range. You can read about CPAP and Bi-level PAP Therapy: New and Established Roles by clicking here.

Ways the CPAP machine reports the AHI

An AHI estimate is calculated by CPAP devices using proprietary algorithms. We sleep doctors think the gadget “pings” your airway with little bursts of air to test if it is open, measuring resistance to the airflow they are trying to provide.


CPAP machine reports the AHI

For example, a CPAP machine will “ping” your airway if it detects a lack of airflow for more than 10 seconds. An obstructive apnea is detected if the air packet is reflected back to the monitor, indicating that the airway was blocked. If the air packet doesn’t come back, it indicates that your airway was clean and that this apnea was central. Hypopneas are thought to occur when there is a sudden and dramatic increase in resistance to the airflow given by the CPAP for at least 10 seconds.

Keep in mind that the cAHI should be viewed with caution because CPAP devices do not conduct diagnostic sleep studies on you on a nightly basis. Visit http://mhsblogs.com/guide-on-how-to-set-up-your-cpap-pressure-correctly/ to read about the Guide on How to Set Up Your CPAP Pressure Correctly.

Is the CPAP AHI reliably accurate?

Not at all true. Keep in mind that the cAHI can provide you a very accurate picture of how well you’re performing overall. Moreover, it is essential to examine the data patterns, rather than relying on a single night’s worth of information, before drawing any judgments. Mask seal, alcohol consumption, drugs, body posture, altitude, and other variables can all affect AHI from one night to the next. Before evaluating whether or not a CPAP machine has to be changed based on the cAHI, we want to gather at least two weeks of continuous data.

By and large, we have found that the AHI from a sleep study done on the same patient while they were using CPAP is much greater than the cAHI from the CPAP machine. The cAHI may be grossly underestimating the true incidence of residual abnormal breathing occurrences, as …

How often should you visit a Sydney eye clinic
How often should you visit a Sydney eye clinic

Your age, as well as your eyes, family, and other factors, have a role.

Your doctor could advise regular Sydney eye clinic exams every two years if you’re under 40 and don’t have any eye issues. Or they could inform you that no tests are necessary. Find out their recommendations for you.

Every 1-2 years, everyone 40 years of age or older should get their eyes examined.

You should visit Sydney eye clinic annually if you’ve ever had eye problems or if you’re at risk of doing so (for example, if someone in your family has).

Why? You should get your eyesight checked to discover whether you have any major, often “silent” issues like glaucoma, age-related macular degeneration, cataracts, or diabetic retinopathy.

When your kid is a newborn and again at each routine medical checkup, if they don’t have any risk factors for eye issues, their eyesight should be assessed. It will be simpler for the doctor to evaluate their eyes when kids are 3 years old. Every one to two years after the first grade, kids should get their eyes checked.

Are My Eyes in Danger?

You may need more regular tests if you have a health issue like high blood pressure, perform a profession that demands a lot of eye contact, or use medications that might impair vision.

Get your eyes tested if you have type 1 diabetes within five years of your diagnosis and then annually after that.

If you’re told you have type 2 diabetes, you should be checked out right away. After that, get your eyes tested annually.

How to Get Ready

Mention any visual issues you may have when you call to schedule your test.

Make a note of any questions you have for the doctor before you visit. Be prepared to give them an update on any medications you use as well as your (and your family’s) history of eye health.

Bring the prescription, your glasses, and your contact lenses. Bring sunglasses as well for the return journey. To dilate your pupils, the doctor could use eye drops. It is known as dilation. After that, light sensitivity will affect your eyes.

When You Get a Sydney Eye Clinic Exam

The eye doctor or a member of the office staff will first inquire about your past medical and visual history.

Depending on the technology utilized, the test might run anywhere from 30 minutes to several hours. It will cover your eye health and eyesight.

The majority of the following Sydney eye clinic exams, as well as maybe a few more, will likely be performed on you:

Test of eye muscle movement: This determines the alignment of your eyes. The physician will observe how your eyes move while you track a moving object (such as a finger tip or their pen) as it changes direction.

The cover test reveals how effectively your eyes cooperate. You’ll fix your gaze on a little object in the distance. To measure how much your eyes move, the doctor will cover and uncover each eye. Additionally, your doctor will be looking for an eye that shifts away from the intended target. Strabismus is the medical term for this issue. You are welcome to retake the Sydney eye clinic exam with a nearby target.

External examination and student responses 

The doctor will observe how your pupils respond to light and nearby objects. Your eyelids’ posture and the whites of your eyes will also be examined at the same time.

You’ll sit in front of an eye chart with progressively smaller letters as you read down each line to undergo a visual acuity test. You’ll cover each eye in turn and read aloud while moving down the chart while using the other eye until you can no longer make out the letters.

Refraction testing: The doctor might use a computerized refractor to determine your precise lens prescription. By switching the phoropter back and forth between lenses and asking you which is better, your doctor will adjust the prescription. You won’t need this Sydney eye clinic exam if you don’t need corrective glasses.

The slit lamp (biomicroscope) enlarges and illuminates the front of your eye. In order to search for …

Handy question tips that help during Sydney eye clinic appointments
Handy question tips that help during Sydney eye clinic appointments

What questions are you asking your Sydney eye clinic patients? By spending four minutes asking these eight questions, you can significantly increase both your capture rate and your second pair sales.

Who knows, you may even uncover additional medical conditions as well!

  • Please describe what you currently wear?
    This simple question helps determine what the patient is wearing, and just as important, what they are not wearing. It is a good ice breaker question. It also gives the Sydney eye clinic direction about other visual options that the patient needs such as sun wear, occupational wear or contact lenses.
  • Describe what you dislike about your current visual solution?
    This question is built to determine where to focus, and which areas you need to fix or alter. For example, a patient may report glare at night, giving you a great reason to prescribe new visual solutions.
  • Do you have any special vision needs for your hobbies or occupation? Please describe. This opens the door for a conversation about second or third pairs of eyewear.
  • Do you suffer from any of the following? Eyestrain, dry or irritated eyes, itchy eyes, fluctuating vision, headache, or red eyes.
    This question is to pull out visual issues that many people do not associate with allergies, dry eyes, accommodative issues, or convergence issues.
  • How many hours a day/night do you use a computer? 
    The goal of this question is to determine the patient’s near point needs and the potential need for occupational eyewear.
  • Do you have trouble focusing in the distance after reading or using the computer for more than 10 minutes? 
    This helps identify accommodative or early presbyopia problems.
  • Do you have trouble reading street signs or with seeing glare from oncoming headlights at night? 
    We are looking for glare issues and the ability to sell anti-glare solutions.
  • Will you be purchasing eye wear, sun wear or contact lenses today?
    Use this as your final question. If the answer is “yes,” it will be an easy sale. If the patient says, “maybe,” you need to look for prescription changes.

Preparing ahead of time can help you best manage your vision health. Here are some questions you can take along when you visit a Sydney eye clinic.

  • What tests will we be doing today, and do they include a dilated Sydney eye clinic exam to check for diseases such as glaucoma and macular degeneration?
  • Is there anything about my medical or family history that puts me at higher risk for eye disease?
  • Are there symptoms to watch for and ways to monitor my eye health?
  • How often do you recommend I return for a comprehensive Sydney eye clinic exam?
  • Are there lifestyle changes that might lower my risk?

Things to bring to your appointment:

  • Your health insurance information and a photo ID
  • Eyeglasses or contact lenses you currently wear
  • Information on any history of eye disease in your family
  • A list of your medications, allergies, and other conditions
  • A notepad and pen, or digital device, to take notes
  • A friend or relative to accompany you if possible

If You are Diagnosed with an Eye Disease

Take an active role in the understanding and treatment of your condition. Here are some questions to ask your Sydney eye clinic when you discuss your diagnosis.

  • Am I likely to need medications or surgery, now or in the future?
  • Do these medications have any side effects?
  • Will insurance cover these treatments, or is financial assistance available?
  • What symptoms should I watch for, and do I need to contact you about any right away?
  • Should I be concerned about driving?
  • How often will you check my eyes to make sure they are not getting worse?
  • Could I benefit from low vision services–such as occupational therapy or technological aids–to help me use my remaining vision?
  • Do you have any materials or other suggestions on how I can learn more about this disease?
