CPAP Newsletter: CPAP News Letter - Issue: 7
Our newsletter is designed to provide information regarding state-of-the art equipment and the latest techniques to treat sleep apnea. We hope it is interesting and helpful to you as you work to optimize your apnea treatment.
The New England Journal of Medicine has published a major new Canadian study demonstrating major improvements in heart function gained by treating sleep apnea with CPAP. Measured results of CPAP only treatment include:
- Sleep Apnea Episodes decreased by 80 percent.
- Heart Function Improved. Hearts pumped an average of 35% more blood per beat after one month of treatment.
- Heart Size Decreased nearly 6%.
- Blood Pressure Decreases from an average of 126/62 to 116/59.
- Heart Rate Decreases from 68 to 64 beats per minute.
Patients in the study used CPAP only at night, and the measurements were taken during the day. The treatment had beneficial carry-over effects, which last throughout the day. For more information go to
Fisher & Paykel has improved the Foam Cushion in the Aclaim II Mask. The mask is now seals better and is more comfortable in the bridge of nose and eye area. We are stocking this with both the medium small and medium large cushions. Fisher & Paykel is rumored to be releasing a number of new products in time for the national sleep meetings scheduled for June 3-7 at the Hyatt Regency in downtown Chicago. Expect to read about a number of new products in next months newsletter as the manufactures prepare product releases.
Respironics has released new Comfort Select Mask Cushions for the small, small wide, and medium sizes. Performance is reported to be much better. We have these in stock.
What is the biggest cause of premature CPAP and BiPAP failures? Drops? Power surges? No. It is water damage! No, not floods. Humidifier use. Just raise the humidifier up above the machine and tilt and all that water flows directly into your machine. The simple act of moving your equipment around can suddenly result is a big problem.
What happens when water is poured into a machine? Some machines are designed so that the water travels harmlessly thru the air outlet, down thru the motor fan assembly, onto the bottom of the machine, and out the bottom of the machine onto your table top. Bad for the table but good for your machine. We like this approach as drying the table is easy enough.
Unfortunately, many models do not consider accidental water invasions in the design. In these machines, water can run onto circuits, fill air sensor lines, and pool within the machine, causing all sorts of expensive damage. It is not unusual to scrap a machine completely due to corrosive damage.
So what should be done if water is accidentally poured into a machine? Don't be sad, you can often get it working. Here is what to do:
- Assuming the wall socket area is dry, unplug the machine from all power. (Caution! never contact a wet area when power is present.)
- Take the machine, hose, and mask to a sink. Empty all water from the hoses into the sink. Pour as much water out the machine as possible. Turn it every which way that allows the water to flow out of any openings.
- Service the filter(s). They are often wet and need to be dried or replaced.
- Completely dry the outside of the machine. Be sure the plug in area is dry. It is going to be plugged in to power, so be absolutely certain no water is on the outside of the unit.
- If a hair dryer is available, blow medium heat at a maximum flow setting into the machine air inlet. Take the filters out for this! After 15 minutes, blow air into the outlet for 15 more minutes. This should dry your machine out nicely.
- With a towel ready to wipe up any water blown out the main hose connection, plug the machine in and turn it on. Yes, really. Do not wear the mask as water may be blown out. Nine times out of ten, the machine will fire up and blow water out. They may not run normally at first as remaining water affects performance. Most model will run fine without the mask on a face. Let the machine run for a few hours, This will completely dry out the inside of the machine on most models. You have saved the machine from serious damage. After the three hours, breath on it a bit. If it does not feel the same, it will need to go in for service.
- Some machines will not run properly when there is no person at the end of the mask. It is very difficult to get the water out of these units. Either use a hair dryer for a hour or more or send it to a dealer for repair. If less than a third of a cup of water entered the unit, it will likely be fine. If it took more, you may be forced to get it serviced.
There is a one way valve Respironics designed to prevent supplemental oxygen from flowing into machines. It is called a Pressure Valve. We tested this item and found it works great in preventing water from being accidentally poured into a machine.
