Sleep apnea negatively impacts the well-being and health of nearly 20 million undiagnosed Americans.1 Left untreated, this sleep disorder is tied to both short- and long-term health complications. For people who make their living driving, untreated sleep apnea impacts the ability to focus and slows reaction times. It may also contribute to daily headaches. A study sponsored by the Federal Motor Carrier Safety Administration (FMCSA) reported that nearly 28% of commercial truck drivers suffer from mild to severe sleep apnea.2 

What Are the Risks When a Trucker Has Sleep Apnea?

In addition to the short- and long-term health risks of sleep apnea, truck drivers face additional work-related risks. Drivers with sleep apnea are five times more likely to be involved in a crash, estimated to cost upwards of $15.9 billion a year.2 Sleep apnea occurs when the airway closes during sleep. Breathing stops and oxygen flow to the brain is restricted. These periods are known as apnea events. In severe cases, apnea events can happen up to 30 times per hour. This many times can cause patients to stop breathing for up to 10 seconds. This lack of oxygen flow while sleeping can cause drowsiness similar to that of the legal blood alcohol limit.2

How Can CPAP Therapy Help Truckers?

A study released in September 2012 at the European Respiratory Society’s Annual Congress in Vienna compared two groups of sleep apnea patients: those who drove commercial vehicles, and those who did not. Members of both groups were similar in age, weight and the frequency of sleep disturbances per night.

According to results, drivers consistently reported to be less sleepy and more alert than non-drivers, although both groups were in therapy with CPAP machines and had a similar number of sleep disturbances. On a sleepiness scale, drivers had an average reported score of 8.1, compared with 11.0 in the non-driver group. After six months of CPAP therapy, both sets of numbers improved, but drivers still reported less sleepiness: 4.8 vs. 7.7.3

Interestingly, the study’s authors believe that the drivers may have reported lower scores because they thought higher scores could jeopardize their jobs.

The good news is that sleep apnea doesn’t have to hinder a truck driver’s career. With CPAP therapy, truckers are able to effectively treat and manage sleep apnea. And today’s sleep equipment offers several CPAP machines and accessories designed for patients on-the-go.

Why Do Truckers Struggle with Sleep Apnea?

In the past, CPAP therapy has been considered cumbersome due to heavy machines and claustrophobic masks. For those that make their living driving,  the added difficulty of finding power sources and effective ways to clean equipment have made CPAP compliance a burden. 

In recent years, however, new technology and design innovations have allowed companies to improve CPAP equipment to be sleek, portable, and fit easily into any lifestyle. Commercial drivers do not need to feel burdened by their CPAP therapy and can now seek effective, comfortable treatment.

Taking Sleep Apnea on the Road with Travel CPAP Machines

For truck drivers (and even cab drivers, bus drivers or pilots) who suffer from sleep apnea and are currently on therapy, The CPAP Shop recommends a travel CPAP machine.

Not only do studies show that the use of a CPAP mask and machine can reduce these work-related problems, but a well-enforced compliance program can generate a return on investment in the form of savings on medical costs, accident reduction, reduced turnover and increased productivity.

A number of trucking companies are recommending and/or utilizing travel CPAP machines for truckers. This is especially true with long-haul truck drivers who have tested positive for obstructive sleep apnea.

Leading companies such as Respironics and ResMed have worked aggressively to create what is considered among the most effective and technologically advanced travel CPAP machines currently available. These new travel-friendly CPAP machines are lightweight and portable, designed to save space while delivering the same powerful therapy as their home unit counterparts.

CPAP Batteries for Long Haul Performance

Interstate drivers often face limited access to power while traveling. For these instances, CPAP batteries are highly recommended. The lithium ion Freedom Travel Battery works with most CPAP and BiPAP machines and can be used as a back-up power supply. Drivers can rely on the Freedom Travel Battery for power outages, emergencies or even use the battery to charge their phone or tablet.

Freedom Travel Battery

For drivers with a Philips Respironics DreamStation Go Travel CPAP Machine, the DreamStation Go Overnight Battery is an excellent choice. The battery requires no special adapters and can also be used as a permanent power backup device.

Another highly recommended option for users of both the DreamStation Go Auto and AirMini is the Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply. If using this battery, however, it does require an adapter.

Plus, with the Freedom 40W Solar Panel, you can charge your battery from the sun while you are out for the day. Charge times vary depending on the amount of direct sunlight available. These work particularly well with the ResMed AirMini.

Sanitizers Keep Your CPAP Gear Clean While Traveling

Interstate travel gets dirty with road dust and soot. It can be a struggle for drivers to find the time and the best place to maintain sanitary conditions for their CPAP equipment. Many drivers turn to sanitizers for convenient CPAP sanitation.

The SoClean 2 CPAP Cleaner and Sanitizing Machine destroys 99.9% of bacteria, viruses and mold on masks, headgear, tubing, and water chambers using activated oxygen. A short, automated cycle gives peace of mind to any trucker concerned about getting sick from CPAP.

The Sleep8 CPAP Cleaner & Sanitizer Device is a more travel-friendly ozone sanitizer that requires no special adapters or connectors. Simply drop the humidifier chamber, tubing, CPAP mask and headgear into a sanitizer bag and press start. With no extra cords or water, this unit works well for sanitizing CPAP gear on the front seat of a semi. And it fits in the palm of your hand!

Truckers With Sleep Apnea and Respiratory Illness

Many drivers may be contending with more than just sleep apnea. Asthma and other respiratory illnesses may be compounding their OSA. Nebulizers are the ideal solution to ensure easier breathing by misting essential respiratory medications. Innovative on-the-go machines perfectly suit the interstate truck driver.

The Philips Respironics Innospire Go Portable Mesh Nebulizer allows for fast and easy treatments for busy drivers. Typical treatments are completed in 5 minutes and one charge is good for 30 treatments. Visual and audible alerts let drivers know when treatment is complete so they can focus on the road and not their medication.

Importance of Travel CPAP Machines for Truckers

An increasing number of trucking companies are mandating compulsory treatment and trucking organizations are recommending treatment benchmarks to continue driving. The Sleep Quality Indicator and data monitoring capability of travel CPAP machines makes it easier for medical professionals to monitor compliance and effective treatment. Consequently, drivers with OSA can get the rest that they need and stay on the road.

Schneider National, one of the country’s largest trucking companies, instituted a sleep apnea screening and treatment program several years ago, partnering with ResMed Corporation. With the use of their CPAP machines and masks, the program resulted in a 73% reduction in preventable driving accidents among a group of 225 drivers diagnosed with Sleep Disorder Breathing (SDB).4

In addition to the accident reduction, its cost savings and worker productivity increased, and medical treatment costs were cut in half. Schneider National’s sleep apnea initiative has saved the company $538 per driver each month in health care savings and yielded a 55% greater retention rate among participating drivers. Additionally, Schneider’s annual cost increase on health care claims has remained lower than industry norms.5

With truck drivers being a vital link for moving the nation’s goods as well as being a major factor on its highways, truck drivers with OSA must seek proper treatment. Travel CPAP machines are among the best options for sleep apnea therapy on the road. Better sleep resulting in alert and healthier drivers on the roads.

If you notice odors on your CPAP equipment, it may be time for a good cleaning. From your mask to tubing to filters, there are many places where bacteria and mold can flourish on your CPAP equipment and cause a bad smell.

Your CPAP Machine Could Smell Bad Due to Dirty CPAP Filter

Your CPAP filter is constantly working to prevent airborne particles and pollutants from entering your tubing and mask. Over time, the filter can become caked with these contaminants. You may notice reduced airflow from your machine. A dirty filter can eventually allow these airborne particles into your airflow, which can contribute to health problems.

You May Have a Dirty Filter if:

  • Your CPAP machine becomes uncommonly noisy.
  • You notice dirt or discoloration on the filter.
  • There is a decrease in your air pressure without you changing the setting.
  • You notice a musty or unpleasant odor.
  • You have lung, airway, or throat irritation.

Cleaning Your CPAP Filter

You should check and clean your filter on a regular basis so that you are getting the most out of your CPAP treatment. To clean your filter, you can follow these simple steps:

  1. Remove the filter from the CPAP machine.
  2. Rinse with warm water and mild detergent to remove any debris or discoloration.
  3. Let it air dry completely before reinserting.

Note: if your filter still appears dirty or worn after cleaning, it may be time to replace it. Replacing a clogged or older filter can alleviate a bad smell coming from your machine, and once replaced, the new filter will work effectively to provide clean and quality air. 

How Does Mold Make CPAP Air Smell Bad?

If you use a humidifier with your CPAP machine, there is the possibility of mold growth. That's because although the humidifier is made to provide a more comfortable experience, the added water it needs can lead to mold and mildew in the water chamber, tubing, mask, or filter. The first sign of mold is usually a musty odor. Along with the unpleasant smell, mold can also contribute to respiratory health issues.

Signs That There is Mold in Your CPAP Equipment

Mold can grow anywhere on your CPAP machine where moisture is present. You can tell when mold is growing because of the musty odor. You can also check for the appearance of mold, usually around the connection points between the humidifier and the CPAP machine. Mold can also cause discoloration on your mask or tubing. Additionally, if you notice you have respiratory irritation or sinus congestion, that is a strong indication you have mold or mildew growing inside your CPAP equipment.

How to Prevent Mold from Growing in Your CPAP 

It's important to note that mold can arise within a day or two when exposed to a wet environment. The best way to prevent mold is to follow a regular cleaning schedule for your CPAP equipment. Here are some steps to take to prevent mold from growing:

  • Clean your mask and hose regularly.
  • Drain, clean, and dry the humidifier water chamber and around connection ports on your CPAP machine every morning after treatment.
    • Use distilled water in your water reservoir.
    • Replace your reservoir every 6 months.
  • Make sure the CPAP machine is properly ventilated and check your humidity controls to prevent producing excess moisture with the humidifier.
  • Disinfect your CPAP equipment with cleaning wipes between cleanings.

You can also use a CPAP sanitizer to ensure the most thorough cleaning process. Sanitizers are an easy and effective way to rid all your equipment of germs, mold, and bacteria. Learn more about sanitizers.

How Can Bacteria Cause Problems?

Even if you do not use a humidifier, moisture particles are still present in your breathing because of its commonness to thrive in a dark, damp, and warm environment. Eventually, this moisture can contribute to bacterial growth. Bacteria can cause an unpleasant odor as well as lead to respiratory infections and other health issues.

Signs There is Bacteria in Your CPAP Equipment

Your CPAP equipment may have a musty or foul odor if there is bacteria in your CPAP equipment. Sinus and respiratory infections may also arise due to this, as well as skin rashes or irritaion around where your CPAP mask typically sits on your face. Additionally, bacteria is likely to grow when there is existing mold or mildew growth.

Solutions to Avoid Bacteria in Your CPAP Machine

Bacterial growth can be prevented with regular cleaning and disinfection of your equipment. If you use a humidifier, be sure to only use it with distilled water to help reduce bacteria. And always replace filters and parts like tubing as needed when they become worn. Other solutions include:

  • Drain and dry your humidifier water chamber every day.
  • Clean and replace your filter according to your machine's user guide.
  • Use mild soap and warm water and least once a week to properly clean your CPAP equipment.

Why Dirty CPAP Masks Smell Bad

The one part of your CPAP equipment that is most likely to start to stink is your CPAP mask because of its constant contact with your face. Your mask comes into contact with your skin so it can accumulate oil, sweat, and other buildup, as well as skin cells from your face with daily use. This buildup of bacteria and mold can lead to a foul odor without proper care.

Your CPAP Mask is Dirty If:

  • You smell a foul or musty odor coming from it.
  • Your mask looks worn out or has discoloration.
  • It leaks regularly throughout the night.
  • You notice increased breakouts and other skin irritation on your face.

Avoiding Dirty CPAP Masks

Follow a daily cleaning routine not only for your face but for your mask as well. Use a mild soap and water to clean your mask and ensure the mask is completely dry before use. You should also replace your mask regularly to ensure the highest level of sanitation and performance. Also, avoid touching your mask when your hands are not washed to prevent the transfer of germs.

How Can A CPAP Cleaner Remnant Cause a Foul Soul?

Sometimes even after you have cleaned your equipment you may detect an odor. Be sure you are thoroughly rinsing the cleaning chemicals off the equipment. Residual cleaning agents can leave a smell. Over time, if they are not thoroughly washed off, the cleaning agents can build up.

Solutions for CPAP Cleaner Remnant

Be sure to thoroughly rinse your equipment after using cleaning chemicals. Use mild cleaning solutions like a mild soap or dish detergent. Strong cleaning chemicals may be more difficult to wash off. Make sure all the parts of your CPAP equipment are fully dry before reassembly.
