Welcome to the definitive ResMed AirSense 11 Travel Guide, your go-to resource for unlocking the full potential of this remarkable device while on the move. Whether you’re a seasoned traveller or embarking on your first journey with the ResMed AirSense 11, our comprehensive guide is designed to empower you with the knowledge and insights you need to ensure a comfortable and restful experience wherever your adventures take you.

AirSense 11 Travel Specifications

Whether you’re planning a weekend getaway, a business trip, or an extended vacation, understanding the specific requirements and considerations for using your AirSense 11 away from home is crucial. This section will discuss the size and weight of the AirSense 11, the environmental conditions under which it is functional as well as its power requirements.

AirSense 11 Size and Weight

The AirSense 11 is a modern, cutting-edge device and in so being, it is versatile and features a sleek, compact design. It has dimensions of 259.4mm x 138.5mm x 94.5mm, making it extremely space-efficient for a full-sized CPAP machine. Weighing in at just 1130g with its 380mL humidifier, this machine provides both comfort and convenience.

Making the AirSense 11 More Portable

Travelling with your AirSense 11 CPAP device opens up a world of possibilities, allowing you to explore new destinations while staying committed to your sleep apnea therapy. To make the most of this freedom, it’s essential to optimise the portability of your AirSense 11, ensuring that it seamlessly fits into your travel lifestyle.

From compact travel cases and power options to innovative accessories and packing strategies, we’ve got you covered. Let’s embark on a transformative journey, unlocking the full potential of your AirSense 11 as your trusted travel companion. Discover how to make your device as portable as your sense of adventure, ensuring that nothing stands in the way of your restorative sleep while exploring the world.

Removal and Disabling of AirSense 11 Humidifier

As we mentioned earlier, the design of the machine includes an optional side cover that can replace the humidifier tub, effectively downsizing the device. However, you may not know how to go about doing this.

To remove the humidifier from your device, hold the humidifier tub from the top and bottom, press gently and pull it away from the device. Please make sure that you handle the humidifier tub with care. The humidifier tub can be replaced as simply as gently inserting it into the side of the device. 

The side cover can be inserted into the AirSense 11 with the same simplicity as with the humidifier and there are no special instructions or differences for how to use it with your AirSense 11.

To disable the humidifier, enter the “My Options” menu, select “Humidity Level” and adjust the setting to off.

How do I prevent my mouth getting dry while using the AirSense 11 on the go?

The comfort and fit of your mask play a significant role in the effectiveness of your CPAP therapy. When travelling, it is important to consider mask options that are suitable for your needs.

When using battery power, the option of using a humidifier is limited as it may drain the battery quickly. In such cases, using a Heat and Moisture Exchanger (HME) mask is recommended. However, it’s important to note that ResMed’s HME masks are only compatible with the AirMini machine. Alternatively, BMC HME masks can be used with any machine, although they may not be as comfortable as regular masks.

These waterless humidifiers provide users with extra comfort by retaining the moisture and heat from the air you breathe and delivering it back into the sleep therapy breathing circuit. When you exhale, the HME filter captures heat and moisture and stores it within its tiny paper ridges. When you inhale, this heat and moisture is released to humidify the air you breathe in, offering relief from possible dryness and congestion. HME is ideal when travelling without a humidifier to environments where the humidity levels are low.

AirSense 11 Travel Accessories

When it comes to travelling with your AirSense 11, the right accessories can make all the difference in terms of convenience and comfort. In this section, we’ll explore a selection of travel accessories specifically designed to enhance your AirSense 11 experience while you’re on the move. Whether you’re embarking on a cross-country road trip or jetting off to exotic destinations, these accessories will ensure that your CPAP therapy remains seamless and effective.

AirSense 11 Travel Bag

Investing in a dedicated travel case for your AirSense 11 is a smart choice. These cases are designed to protect your device during transportation and provide organised storage for your CPAP essentials. Thankfully, your AirSense 11 comes included with a compact and lightweight travel bag that fits snugly into your luggage or carry-on, ensuring that your device is well-protected while travelling.

ResMed recommends that you use the travel bag when travelling to prevent damage to the device. It is also highly recommended that you empty the humidifier and pack it separately in the travel bag if you intend on bringing it with you.

If you need a second bag or a replacement, you can find them available for purchase separately here.

Battery Pack for AirSense 11

When it comes to travelling with a CPAP machine, the first order of business is to find a power solution that will keep your therapy uninterrupted during the night. Thankfully, CPAP battery packs, such as those made by Medistrom, are here to save the day.

What is Medistrom?

Medistrom is a well-known company that specialises in providing innovative power solutions for CPAP machines. They are known for their high-quality and reliable backup power options that ensure uninterrupted therapy for CPAP users, especially during travel or in areas with limited access to electricity.

Medistrom’s CPAP battery packs are compact, lightweight, and compatible with various CPAP machines from popular brands. These battery packs act as a backup power source, allowing users to continue their therapy even in situations where mains power is not available, such as camping, road trips, or during power outages.

Not only is the CPAP battery great for travel, it’s an ideal backup power solution for home too. Attach the Pilot-24 Lite or Pilot-12 Lite series between your CPAP and the wall and then the rest is simple… If your power goes out, due to a storm or other anomaly, the Pilot Lite will take over automatically ensuring you continue to receive restful, uninterrupted sleep therapy. When the power comes back on the Pilot Lite will automatically recharge so it’s ready the next time you need it.

Current FAA regulations allow Sleep Apnea Therapy Devices (CPAP & BiPAP Machines) and Lithium Ion Batteries (like the one in this battery pack) to be carried onboard commercial flights and are usually not counted toward your weight limits; however it is always important to check with your airline prior to travel to determine exactly what requirements they have for carrying medical equipment on board.

The ResMed AirSense 11 is compatible with the Medistrom™ Pilot-24 Lite Battery and Backup Power Supply for 24V PAP Devices. You will need to purchase a ResMed AirSense 11 cable to enable compatibility as the Pilot-24 Lite Battery does not come with an AirSense 11 cable out of the box.

AirSense 11 DC-DC Converter

Another accessory that can help on the road are DC/DC Converters. These converters plug into a cigarette lighter socket and convert their output to one that is suitable to power your CPAP machine. ResMed offers a DC/DC converter for the ResMed AirSense 11 which can take the power from a 12V output cigarette lighter socket and convert it to a 24V output (drawing approximately 1 amp of current). Alternatively, if your source of DC power is already 24V, the converter will ensure a cleaner, more consistent output so that you do not damage the sensitive electronics in your device.

AirSense 11 Cleaning Accessories

Maintaining your CPAP machine is crucial for the effectiveness of your CPAP therapy and this is not an aspect of your therapy that should be neglected while you are travelling. We recommend that you pack travel-sized CPAP wipes or a portable cleaning kit to ensure your AirSense 11 remains clean and operational during your trip. If you’re looking for something to start with, CPAP Online Australia offers a wide range of cleaning supplies for CPAP cleaning and maintenance.

It’s best to avoid using tap water to clean your AirSense 11, especially in unfamiliar locations. Tap water might contain impurities that could harm your machine or irritate your airways. Instead, use distilled water or pre-packaged CPAP wipes to ensure safe and hygienic cleaning on the go.

Running the AirSense 11 during travel

Using the AirSense 11 in a caravan or RV

For travellers exploring the open road in caravans or recreational vehicles (RVs), charging the AirSense 11 battery is convenient and seamless. Most caravans and RVs are equipped with electrical outlets, making it easy to connect the AirSense 11 to the vehicle’s power system. This ensures a stable and consistent power supply for your CPAP therapy while you’re on the move.

Before setting off on your journey, ensure that your vehicle’s electrical system is compatible with the AirSense 11’s power requirements (discussed in detail above). Caravan charging offers a reliable solution for AirSense 11 who prioritise comfort and leisure during their travels.

Using the AirSense 11 in the car

When you’re travelling by car and want to keep your AirSense 11’s battery charged while on the road, a cigarette lighter charger may be your best option. Some CPAP battery packs, like the Medistrom Pilot Lite batteries are also equipped with a DC adapter that allows you to charge the battery using your vehicle’s cigarette lighter port.

While using the cigarette lighter charger is convenient, especially during road trips, it’s essential to be mindful of your vehicle’s battery. Charging your CPAP battery from the car’s battery can drain power, which might affect starting the car later. To avoid this, consider charging your battery pack while the engine is running or use a separate portable power station designed for CPAP machines.

Refer to the above section about the DC/DC converter if you wish to consider this as an option while travelling.

Using the AirSense 11 while camping or during outdoor activities

You can use your AirSense 11 while camping or during outdoor activities by using a portable power source, such as a battery pack or a solar charger. These power solutions allow you to enjoy CPAP therapy even in remote locations without access to electricity.

Medistrom offers a solar charger designed to recharge their CPAP battery packs using solar energy. Their solar charger is portable and efficient, providing a sustainable power solution for users who are constantly on the go.

These portable solar panels are lightweight, foldable, and easy to take almost anywhere with you. However, although solar charging is an eco-friendly option, its effectiveness can vary depending on weather conditions and available sunlight so make sure you make plans accordingly!

Using the AirSense 11 on a plane

You can use your AirSense 11 device on a plane as it meets the Federal Aviation Administration (FAA) requirements.  However, to avoid any issues, we recommend that you contact your airline in advance to inform them about your medical equipment and ensure you meet their specific guidelines. 

If you are travelling to a different country with your CPAP machine, make sure that you are aware of the travel guidelines for your device. Familiarising yourself with airline regulations will allow you to ensure a smooth experience during flights and will equip you to keep your AirSense 11 in the safest possible conditions throughout the entire duration of your journey. Be sure to inform security personnel about your CPAP machine at airport security checkpoints and carry a copy of your prescription or a doctor’s notes to avoid unnecessary complications or questions about the purpose and function of your machine.

When using the device on a plane:

  • Make sure the humidifier is completely empty and it is inserted into your device. The device will not work without the humidifier or side cover inserted.
  • Turn on Airplane Mode.

How to activate Airplane Mode on the AirSense 11

To turn on Airplane Mode:

  1. Go to MORE.
  2. Swipe through the menu to locate Airplane Mode.
  3. Tap Airplane Mode to switch it on.

The Airplane Mode icon should be displayed in the top right of the screen.

By considering these essential factors while travelling with your AirSense 11, you’re well-prepared to embark on a stress-free journey. With the right planning, backup power solutions, and adherence to airline regulations, you can enjoy your adventures while prioritising your sleep apnea therapy.

As you prepare to embark on your journeys with the AirSense 11, remember that the right accessories can be your allies in maintaining a consistent and effective CPAP therapy regimen. Whether it’s ensuring the safety of your device, adapting to varying power sources, or optimising your comfort, these travel accessories are here to support you. By investing in the right tools and making informed choices, you can enjoy the freedom to explore, rest, and rejuvenate—all while knowing that your AirSense 11 is ready to deliver the restful sleep you deserve.
