Built to be worn
Most portable concentrators are a box on a strap that knocks against your hip with every step. CAIRE shaped this one to follow the line of your body, so it sits still while you walk. At 2.3 kg with the standard pack it is light enough to forget about, and the settings, the battery and the dose it gives you are all worked out to keep you out of the house for longer.
1050 mL
Per minute at setting 5
Five settings, rising in even steps of 210 mL a minute. That is a genuine spread for a unit this size, and your clinician sets you on the one that holds your saturation where it should be.
39.9 dB(A)
On setting 2
Between a whisper and a quiet office. Quiet enough to sit through a film or a church service without the person beside you shifting in their seat.
Up to 16 hrs
On the 16 cell pack
CAIRE rate the 16 cell pack at up to 16 hours on setting 1 and 8 hours on setting 2. The 8 cell pack does exactly half of that and keeps the unit lighter. Both are sold on this page.
3 years
Sieve beds included
CAIRE were the first to put the sieve beds inside the device warranty rather than treating them as a consumable. Batteries and power supplies carry 12 months. Serviced by our own team here in Australia.
Before you head out
CAIRE publish a duration for every setting on both pack sizes, so you can find yours and know whether the day fits on a charge before you leave. One detail worth having in mind is that these times hold whatever your breathing rate is doing, which is not true of every pulse concentrator.
Swipe the chart across to read the 16 cell times.
Figures are CAIRE's, for a new battery pack. Real duration shifts with the age of the pack and the temperature, so allow margin on long outings and flights.
It waits for your breath

UltraSense is the trigger. It reads the small pressure change at the cannula as you start to breathe in, and releases the pulse then rather than on a timer. A shallow breath still counts, which matters as the day wears on and you tire.
autoDOSE is the backstop. If the device stops sensing you and a no breath alarm comes up, it does not simply sit there waiting. It begins pulsing on its own at 20 breaths a minute on whatever setting you are running, and keeps going until it picks your breathing up again. A cannula that slips while you are dozing in a chair does not leave you with nothing.
There is nothing to switch on for either of them. Both run from the moment you power the unit up, and the screen keeps up its end as well. Large type on a colour display, a keypad that glows in the dark, and the flow setting and battery percentage side by side, so there is nothing to work out in a dim room.
Mains, car and battery

A backup oxygen supply is worth having for power outages or faults. Your clinician should confirm that your prescribed setting suits the trip, including at altitude.
Unpacking

Spare packs, a desktop charger, a backpack, cannulas and tubing are all in our accessories and parts and oxygen consumables ranges.
Lithium ion batteries
CAIRE state the FreeStyle Comfort meets FAA guidelines for use on board commercial aircraft, and most airlines will carry it. Getting the paperwork and the battery rating checked beforehand is what avoids a problem at the gate.
Airline requirements change, so treat this as a starting point rather than the final word. Call us on 1300 881 824 if you have questions before a trip.
Oxygen should only be given according to the prescription and guidance of a certified healthcare provider. Pulse dose devices must be tested by your healthcare provider to confirm they suit your treatment and to set the correct level.
Settings are not litres per minute. Setting 2 delivers 420 mL a minute, not 2 L/min. Pulse dose delivery is not generally recommended for use while sleeping, as it may not detect shallow breathing. This device is not intended for life support and does not monitor your oxygen saturation.
It comes down to how long you are out against how much you want to carry. The 8 cell pack keeps the unit at 2.3 kg and runs up to 8 hours on setting 1 or 4 hours on setting 2. The 16 cell pack takes it to 2.7 kg and roughly doubles the time. If most of your outings are a few hours and you can charge in the car, the 8 cell is enough. If you fly, or you are out from morning to evening, the 16 cell saves you carrying a spare.
The two things the device does on its own. UltraSense is the trigger, reading the pressure change at the cannula as you breathe in and releasing the pulse at that moment rather than on a timer, so a shallow breath still gets picked up. autoDOSE covers the opposite case. If a no breath alarm comes up, the unit starts pulsing by itself at 20 breaths a minute on your current setting until it senses you breathing again.
CAIRE state it meets FAA guidelines for use on board commercial aircraft. Australian airlines run their own clearance on top of that, so call them at least 48 hours before you fly and ask what paperwork they want. Take enough charged packs for 150% of your total travel time, and remember the packs do not charge in airplane mode.
Ask your clinician before you rely on it overnight. Pulse dose devices are not generally recommended for sleep, because they may not reliably detect shallow breathing. The FreeStyle Comfort is pulse only, so there is no continuous flow mode to fall back on. If your prescription calls for continuous flow, the CAIRE Eclipse 5 and the GCE Zen-O both do it.
Yes. We dispatch the FreeStyle Comfort once we have verified a valid prescription, or proof of professional or business status for clinics, aged care providers and other business buyers. It is pulse dose only, delivering 210 to 1,050 mL a minute across settings 1 to 5, so your healthcare provider needs to test you on the device to confirm it suits your treatment and set your level. If your prescription calls for continuous flow, the Eclipse 5 and the Zen-O both provide it.
CAIRE publish 39.9 dB(A) on setting 2 in their specification sheet, and their user manual lists a maximum of 43 dB(A) on the same setting. Either way it sits below the level of a quiet office and it is one of the quieter units we stock. Higher settings work the compressor harder and you will hear the difference as you move up the range.
Yes. A DC lead is included, rated 11 to 18V for a standard vehicle outlet, and every setting runs on it. The pack charges while you drive, so a long trip can start with a flat battery and end with a full one.
Almost none. CAIRE describe the device as maintenance free, and the filters inside are built to last the life of the unit. Your job is the two gross particle filters on the front, which need cleaning at least once a week in warm soapy water and drying fully before they go back in. Anything beyond that comes to our technical services team here in Australia on 1300 881 824.
A cylinder holds a fixed volume of oxygen and runs out, so the week gets planned around refills and deliveries. A concentrator draws in the air around you, strips out the nitrogen and delivers oxygen at therapeutic purity, so it only stops when the power does. There is nothing to refill and nothing to return.
A valid prescription, or proof of professional or business status (for clinics, aged care providers and other business buyers), is required before this product can be fulfilled or shipped. After placing your order, please call us on 1300 881 824 and quote your prescription number and order number, or email a copy of your prescription or proof of business status to info@megamedical.com.au. Your order will be dispatched once this has been verified.

Patients on oxygen therapy and healthcare providers.
For patients needing oxygen support at home, in hospital, or while moving.
