Sleep is essential for our overall well-being, yet many of us struggle with sleep-related issues at some point in our lives. Whether it’s difficulty falling asleep, staying asleep, or experiencing poor sleep quality, these problems can have a significant impact on our health and daily functioning. In some cases, these issues may be indicative of underlying sleep disorders that require professional attention. This is where sleep studies come into play. In this blog post, we’ll delve into the main reasons why someone might need a sleep study and how it can help improve sleep and overall health.

  1. Suspected Sleep Disorders: One of the primary reasons for undergoing a sleep study is to diagnose or rule out sleep disorders. These disorders can range from obstructive sleep apnea (OSA), characterized by pauses in breathing during sleep, to insomnia, narcolepsy, restless leg syndrome, and parasomnias such as sleepwalking or night terrors. Sleep studies, also known as polysomnography (PSG), help healthcare providers monitor various physiological parameters during sleep, such as brain waves, oxygen levels, heart rate, and muscle activity, to identify patterns indicative of specific sleep disorders.
  2. Chronic Fatigue or Daytime Sleepiness: Persistent fatigue or excessive daytime sleepiness can significantly impair daily functioning and quality of life. While these symptoms can be caused by various factors, including poor sleep hygiene, stress, or lifestyle habits, they can also be a sign of an underlying sleep disorder. A sleep study can help determine if conditions like sleep apnea or periodic limb movement disorder are contributing to these symptoms, guiding appropriate treatment strategies to alleviate daytime sleepiness and improve overall well-being.
  3. Snoring and Breathing Irregularities: While occasional snoring is common and often benign, habitual loud snoring accompanied by pauses in breathing could indicate a more serious condition like obstructive sleep apnea. Sleep studies can assess breathing patterns during sleep and identify any abnormalities that may be disrupting airflow and causing interruptions in breathing. Addressing these issues is crucial not only for better sleep but also for reducing the risk of associated health problems such as cardiovascular disease and hypertension.
  4. Evaluation of Treatment Efficacy: For individuals already diagnosed with sleep disorders, such as sleep apnea, periodic limb movement disorder, or insomnia, sleep studies may be used to evaluate the effectiveness of treatment interventions. Continuous positive airway pressure (CPAP) therapy for sleep apnea, medications for insomnia or restless leg syndrome, or lifestyle modifications may all be implemented to manage sleep-related issues. Periodic follow-up sleep studies can help assess treatment compliance and effectiveness, guiding adjustments as needed to optimize outcomes.
  5. Assessment of Sleep Quality and Architecture: Sleep studies not only diagnose specific sleep disorders but also provide valuable insights into overall sleep quality and architecture. By monitoring different sleep stages (such as REM and non-REM sleep), sleep latency, and sleep efficiency, healthcare providers can assess the overall health of an individual’s sleep and identify any abnormalities or disruptions that may be impacting restorative sleep processes.

Sleep studies play a crucial role in diagnosing sleep disorders, evaluating treatment efficacy, and improving overall sleep quality and health. Whether you’re struggling with chronic fatigue, daytime sleepiness, snoring, or suspected sleep disorders, undergoing a sleep study can provide valuable information and guidance for effective management and treatment. If you’re experiencing persistent sleep-related issues, don’t hesitate to discuss the possibility of a sleep study with your healthcare provider—it could be the first step toward achieving better sleep and a healthier life.

Sleep apnea is an unfortunate and potentially serious ailment that causes one’s breath to be unsteady while asleep. Sleep apnea prevents a person from getting restful, refreshing, restorative sleep due to constant breathing disruptions throughout the night. This article discusses sleep apnea, how it affects the body, and how using a CPAP machine for sleep apnea can help.

What Causes Sleep Apnea?

There are two different kinds of sleep apnea: obstructive sleep apnea and central sleep apnea.

Central sleep apnea occurs when the brain does not send the correct signals to maintain breathing while sleeping. Breathing stops. When this happens, the body alerts the brain to wake up. Once awake, the brain kicks in and picks up the regular breathing pattern, but this action causes an interruption in the sleep cycle. When this happens multiple times throughout the night, it can be difficult to fall into the deep restorative sleep that the body needs.

Obstructive sleep apnea occurs when something obstructs the airway during sleep. Blockage can result from obesity, large tonsils, or hormone fluctuations. Once again, breathing stops. This time when awakened, changing body position shifts the obstruction, and breathing is restored.

One thing that both sleep apnea conditions have in common is the pauses in breathing. The health effects of this condition are different for everyone.

The Effects of Sleep Apnea

Aside from leaving a person tired from a lack of sleep, this condition can cause many other issues, especially if untreated. The lack of deep sleep makes it difficult to find the energy to carry out everyday tasks, including driving, grocery shopping, or walking the dog. Along with fatigue comes brain fog and confusion, which can increase as the mind and body tire.

Another side effect of sleeplessness is depression. Depression often manifests in a lack of desire to be fun or intimate. This condition can worsen the more prolonged sleep apnea goes untreated.

Lack of reparative sleep also weakens the immune system, causing problems with blood pressure, cholesterol, or even heart disease. Fatty liver disease and heightened liver enzymes are also side effects of sleep apnea when left untreated.

The lack of oxygen the body takes in while resting can result in low blood oxygen levels, which can cause dizziness, headaches, shortness of breath, and even chest pains. In addition, sleep apnea can increase the severity of preexisting respiratory problems like asthma.

Sleep cycles can often be a mystery. Whether you wake up rested or restless, you can’t help but wonder what goes on after you close your eyes. Luckily, nowadays, many devices can help track your sleep patterns.

Sleep Apnea

CPAP machines are an excellent treatment for sleep apnea and are designed to track your sleep trends, but this only applies to those already diagnosed with sleep apnea. Therefore, undiagnosed people may need to track sleep patterns themselves.

Wrist Devices & Sleep Movement

Fitbits and Apple Watches can help. These devices and their apps aren’t meant to diagnose sleep apnea or other ailments, but they can help you recognize unhealthy patterns in your waking and sleeping hours. These wearable gadgets contain an accelerometer, which is used to detect movement. Fortunately, when you sleep restlessly, it reflects on your device.

Heart & Respiratory Rates

Many wrist-worn devices also have tools to track your heart and respiratory rates, which can help determine spikes in your sleep patterns. Most sleep trackers contain these elements crucial to pinpointing your sleep cycles. It’s important to note how much of your sleeping hours are spent in REM sleep, the deep sleep that allows your body to repair and replenish itself. Losing hours of this particular cycle can contribute to fatigue and many other health concerns, such as high blood pressure, heart disease, or depression.

Apple Watch

The Apple Watch must track your sleep for at least four hours per night. You can use the watch with a personalized sleep schedule that you’ve created or with the watch’s Sleep Focus setting. After compiling your sleep data, these devices and apps can construct a tailored chart of your trends. For example, the app rates your sleep a score between 1 to 100, with 100 meaning you slept wonderfully and 1 meaning you should probably head back to bed. With these charts, you can study your routines and consult your doctor regarding anything concerning you.

Fitbit

The Fitbit features are very similar to the Apple Watch. While Fitbits are less pricey, they offer much of the same data. Not to mention their batteries are known to last longer. Regardless of your device, utilize these features to see the bigger picture regarding your sleep habits.

Roughly 25% of adults suffer from sleep apnea. The most common treatment for sleep apnea is PAP therapy (positive airway pressure therapy) which delivers air through a mask to help steady breathing while asleep. The CPAP machine is the most common, offering consistent airflow. A BiPAP machine works the same but offers different air pressure levels for inhalation and exhalation. These machines are generally used to treat obstructive sleep apnea.

When is ASV Therapy Used?

ASV therapy is used to treat central sleep apnea. Both central and obstructive sleep apnea involves irregular breathing patterns during sleep, but their causes are unrelated. While obstructive sleep apnea happens because of a blockage in the airway, central sleep apnea occurs when the brain and the muscles that control breathing do not correlate properly.

The failure of the brain to trigger the respiratory muscles, also known as an apneic event, is when an ASV machine is used. This therapy often helps those suffering from central sleep apnea resolve the issue over time. The machine trains the body to breathe correctly without forcing the airflow when it isn’t necessary, which in turn allows your body to pick the pace and learn from its mistakes. Unfortunately, this isn’t always the case, but occasionally this issue can correct itself with treatment.

ASV vs. PAP Machines

ASV machines must be adjusted and modified for the individual. They differ from PAP machines because they monitor breathing while the person sleeps, customizing the air pressure delivered to help steady their breathing. By contrast, CPAP and BiPAP machines provide a consistent, generic airflow.

What is an ASV Machine?

ASV machines include the machine, the mask, and the hose that connects the two. There are also different styles of masks, such as mouth and nose coverings or just the nose. While the machine monitors throughout the night, the machine responds when breathing slows, pushing air flow with enough pressure to regain a steady breathing pattern. Once the target pattern is reached, the machine’s pressure automatically lowers, often still providing a continuous flow, but with much less force, to maintain consistent and repetitive breathing.

If CPAP is uncomfortable for you, or your sleep apnea doesn’t respond well to the treatment, ASV therapy might be a good alternative. In addition, the flexibility in air pressure can be more soothing to sleep with instead of the steady airflow given by the other machines.

Sleep can be a trickier prospect than some people realize. One has to fall asleep, stay asleep, and then wake rested and energized for the new day. At any point in this process, problems can occur. Those problems easily result in improper or lack of sleep. These issues are genuine for those with medical conditions like sleep apnea. Apnea can make it extremely difficult to obtain a good night’s sleep, but what causes it in the first place? It depends on the kinds of apnea at work. This article will discuss the causes and the best treatment for sleep apnea.

Types of Sleep Apnea

There are two common forms of sleep apnea, obstructive and central. Knowing the best treatment will depend on what form it takes.

Obstructive Apnea

Obstructive apnea is a result of brief, interrupted breathing. The muscles in the back of the throat become too relaxed, blocking the airway, and as a result, breathing is stopped. The body then wakes up to prevent asphyxiation –recent research has led some to believe a similar issue causes sudden infant death syndrome. This constant repetition of falling asleep and waking up prevents proper rest.

Central Apnea

Central apnea is neurological in nature and involves the brain not communicating correctly to airway muscles, preventing proper breathing while asleep. This form of apnea is common among stroke survivors. It is also found in persons with heart disease, kidney failure, or using certain opioids.

Other Causes

Apnea can also have other causes and can create all manner of issues, such as high blood pressure. Obesity, smoking, and chronic nasal congestion are potential causes of sleep apnea.

Symptoms

Knowing the warning signs provides an excellent start to finding the best treatment for sleep apnea. For example, loud snoring, insomnia, waking up with a dry mouth, and waking up snorting or gasping for breath are common signs of sleep apnea.

Regardless of the form sleep apnea takes, it is a severe condition that requires treatment. Talking to an expert and testing can confirm the type of apnea one is suffering, and then the proper treatment can be implemented.

It can be hard enough to ensure a good night’s sleep. Having to deal with constant interruptions from apnea makes it nearly impossible to enjoy restful sleep and can create further health issues. Don’t ignore the signs. Determine the cause, and seek the best treatment for sleep apnea depending on the cause and kind suffered. That is the best plan to ensure apnea concerns are put to rest.

Whether hopping on a plane or loading up the car, lugging your CPAP machine with you will take some additional arrangements. Of course, leaving it behind would be easier, but don’t ruin your trip. One night without your machine can flare up those pesky sleep apnea symptoms and keep you from feeling like yourself on vacation. So instead, prepare your CPAP machine for traveling.

Tips for Traveling with a CPAP

Test Equipment

Before departing on a trip, test the CPAP equipment to ensure it is in good working order. Check all attachments for wear and tear and replace any worn or damaged items. If you find any worn or damaged CPAP accessories before your trip, replace them on our CPAP shop.

Moisture-Free Equipment

Ensure all the equipment is dry before packing it. Bacteria and mold can form in moist places, and you don’t want to be breathing in that.

Distilled Water

Even if you’re heading to a high-end resort, bring bottled distilled water. It’s crucial that you only use distilled water in your machine. Tap and spring water contain minerals that can clog up your machine, causing it to malfunction. Also, bring some CPAP wipes, so you don’t waste your bottled water cleaning your device.

Power Supply

The power supply might not be sufficient, depending on where you’re heading. Make sure your power cord works with the outlets where you’re going, and bring a backup battery pack. You never know when you’ll run low or have an unexpected power outage. Invest in a DC converter, an adaptor that can be used with USB ports, car cigarette lighters, or solar power to enhance your power supply options.

Air Travel

When flying with your CPAP machine, it’s good to know whether the model you have is approved for in-flight use – most of them are these days. Check your luggage, not your CPAP. Keep it on the plane with you. Luggage occasionally gets misplaced, and it’s better to be safe than sorry. If you travel often, consider investing in a portable machine with waterless humidification to avoid packing water bottles.

When going through security in the airport, there are a few things to keep in mind that will make it go smoothly. First, TSA agents see these machines regularly and have every right to inspect them. Pack the machine in a clear plastic bag and include a medical device ID tag. Also, if they choose to remove the machine from its packaging, always request they put on new gloves.

Carry a copy of your prescription in your luggage. Although you might not need it, you never know.

Extra Supplies

Carrying extra supplies could be helpful, even on short trips. It’s better to be over-prepared—extra supplies can include mask cushions, filters, headgear, extra batteries, and an extension cord.

Medical Alert Wallet Card

A medical alert wallet card could easily save your life – especially if you are traveling alone. This health history information is vital for first responders treating you if you become unresponsive.

People who have sleep apnea often use a machine to help them breathe while they sleep. Most people have heard about these machines, or at least one of them – the CPAP (Continuous Positive Airway Pressure). But there are other machines used. Another is called the BiPAP. So, what is a BiPAP machine?

The BiPAP Machine

A BiPAP machine, or a Bilevel Positive Airway Pressure machine, helps to regulate breathing on two levels: one for inhaling and one for exhaling. It’s designed to force pressurized air through a BiPAP mask and into the upper airway. This forced air benefits those with respiratory problems or breathing conditions such as sleep apnea.

The machine provides two different levels of air pressure. One is for inhaling, which is known as IPAP, or inspiratory positive airway pressure. The other is for exhaling, also known as EPAP, or expiratory positive airway pressure. The air pressure for inhalation is notably higher than for exhaling. The higher pressure helps the tissue around the upper airway remain unblocked, reduces pauses in breathing and snoring, and can aid in regulating sleep patterns.

PAP Therapies

Everyone’s condition is different, and each individual needs specific treatment, but there is no shortage of PAP therapy options. Consulting a sleep specialist is the first step because a prescription is required to obtain a PAP device. Then, the specialist will determine the treatment option based on your specific condition.

Machine Options

These machines have many ways to help with sleep apnea and many other breathing disorders and respiratory issues. This high-pressure machine is often used to replace others unable to deliver sufficient air to the lungs. Sometimes CPAP, APAP, or ASV machines are not enough for some respiratory conditions – that’s when BiPAP machines are used.

The BiPAP machines have also benefited Covid-19 patients with acute lung function loss. While this machine isn’t a treatment for the virus itself, it does help to maintain consistent breathing patterns. This is called noninvasive respiratory support, and it keeps patients from having to hook up to a mechanical ventilator or utilize intubation.

The machine has a few other components as well. The device that pressurizes the air is where it all begins, then the air is fed through a hose attached to the machine, and on the other end is the BiPAP mask. These BiPAP masks deliver air through the mouth, nose, or both, depending on the one you have. We sell various BIPAP masks and accessories on our CPAP shop. Lastly, a filter purifies the air and a humidifier that heats it slightly as it funnels through the machine.
