Making the ResMed S9 More Portable

Travelling with your ResMed S9 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 ResMed S9, 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 ResMed S9 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.

Travelling With The ResMed S9 Without The Humidifier

The ResMed S9 does not come with a humidifier included, although the H5i Humidifier can be bought and attached to the machine. This makes the S9 extremely small, light and portable in comparison to most other full-size CPAP machines and also means that it can easily operate with a reduced power consumption, through the use of a 30W power supply as opposed to the 90W power supply required for the humidifier to function.

In the event that you are not using the H5i Humidifier, 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.

ResMed S9 Travel Accessories

When it comes to travelling with your ResMed S9, 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 ResMed S9 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.

ResMed S9 Travel Bag

Investing in a dedicated travel case for your ResMed S9 is a smart choice. These cases are designed to protect your device during transportation and provide organised storage for your CPAP essentials. Thankfully, your ResMed S9 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.

Battery Pack for ResMed S9

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 S9 is compatible with the Medistrom™ Pilot-24 Lite Battery and Backup Power Supply for 24V PAP Devices. You will need to purchase a ResMed S9 cable to enable compatibility as the Pilot-24 Lite Battery does not come with an S9 cable out of the box.

ResMed S9 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 S9 which can take the power from a 12V output cigarette lighter socket and convert it to a 24V output. 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.

ResMed S9 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 ResMed S9 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 ResMed S9, 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 ResMed S9 during travel

Using the ResMed S9 in a caravan or RV

For travellers exploring the open road in caravans or recreational vehicles (RVs), charging the ResMed S9 battery is convenient and seamless. Most caravans and RVs are equipped with electrical outlets, making it easy to connect the ResMed S9 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 ResMed S9’s power requirements (discussed in detail above). Caravan charging offers a reliable solution for ResMed S9 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 ResMed S9’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 ResMed S9 while camping or during outdoor activities

You can use your ResMed S9 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 ResMed S9 on a plane

You can use your ResMed S9 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 ResMed S9 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.

Do not attach the S9 Modem Module to your device when travelling with it by plane.

By considering these essential factors while travelling with your ResMed S9, 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 ResMed S9, 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 ResMed S9 is ready to deliver the restful sleep you deserve.
