  • iCH & XT

    • Q1: When traveling abroad, does the patient need a converter?

      No, there is no need to use the converter as Apex’s CPAP systems can accept 100-240V, 50-60Hz, without any special adjustment. An international plug adapter may be required to make the power cord compatible with the power outlets of that country.

    • Q2: Can the patient power the device by a battery or a car adapter?

      The XT series CPAP system doesn’t have DC capability so it can’t be powered by a battery or a car adapter. However, it can be used with a DC to AC inverter (only CPAP, not the heated humidifier).  The iCH series CPAP system can operate with an inverter or converter. The converters allow users to operate the device from a 12V or 24V DC power source.

    • Q3: Is there any alarm function?

      Yes, the XT & iCH series CPAP (except entry-level models) have a Low Pressure alarm function. When there is a large leak, the device will show “Low P” on the display to remind the user to check it. If the user activates the audible alarm function, the device will have a beep sound when showing “Low P”.

    • Q4: Is there patient software available to view reports/progress?

      Yes.  The Easy Compliance Lite can be used to view reports.

    • Q5: What is ramp?

      The ramp button on a machine is a feature that allows for a gradual pressure build-up to your prescribed pressure. The feature is enjoyed by those with high pressures because they ease up to their pressure.

    • Q6: What is PVA Pressure Relief?

      Pressure Variation Algorithm (PVA) is a comfort feature designed to reduce the air pressure during exhalation to create a more natural breathing pattern.  Select from a setting of zero to three, with three being the greatest drop in pressure and one being the smallest drop in pressure. Select the zero setting to turn the PVA feature off.

    • Q7: Do any of the units offer an exhalation relief option?

      Yes, the iCH Auto, XT Auto and XT Prime offer the PVA Pressure Relief function. 

    • Q8: Can the patient set or change the pressure settings?

      As a medical device that requires a prescription, the settings should be changed or adjusted by the medical provider.   

    • Q9: How many hours of humidification will the patient receive with a full chamber of water?

      The humidifier chamber, which is 450 ml for XT and 300 ml for iCH, will provide humidification for at least 8 hours per night. This has been validated under the most extreme conditions of pressure setting, humidification setting and sleep environment. 
      Note: Excess mask or other system leak will increase water consumption.

    • Q10: Will the humidifier run if there is no water in the chamber?

      If the water chamber is placed correctly to press against the small switch, the humidifier will continue to control heat to the set level even if there is no water in the water chamber. When the temperature of the heating plate is too high, the humidifier will automatically stop heating and recover to heat when the temperature cool down to the set range. This situation will not cause damage to either the humidifier or the humidifier chamber.

    • Q11: Is there any possibility for water chamber leak?

      For the XT Series units, leaks may result when the metal base does not connect to the chamber properly.  To prevent this, make sure the metal base of the water chamber has been pushed to the end to have a good seal.  In addition, the aging of the silicon on the metal base may also cause leakage. If this is the case, please contact your supplier for a replacement of either the silicon band or the one provided by the water chamber.

    • Q12: Is the water chamber dishwasher safe?

      Note that the material of the water chamber is dishwasher safe. However, it may cause the damage of the middle silicon seal and speed its aging. We recommend a manual soap and water bath instead of using the dishwasher.

    • Q13: Can the patient use tap water with the humidifier water chamber?

      Tap water is not recommended as it will leave hard white mineral deposits as the water evaporates or it may lead to mold growth. We recommend distilled water as it helps keep the humidifier water chamber clean and mineral deposit free.
      If distilled water is not available where you live or are traveling, we recommend using bottled water.  Note- it is important to clean the water chamber each morning and not leave standing water in the water chamber between uses; regardless of type of water used.

    • Q14: Can the patient use other filters (for example, the white one) instead the gray foam provided by the manufacturer(black one)?

      The device uses a gray foam filter that is washable and reusable. Using different filters which is not provided by the manufacturer may affect the performance of the system. The gray reusable filter must be in place at all times when the device is operating.

    • Q15: How long does the patient need to replace the filter?

      The air filter should be cleaned at least once every two weeks or more often if this device is operated in a dusty environment and replaced with a new one every six months.

    • Q16: Are there fuses for the patient to replace?

      There are no user-replaceable fuses.

    • Q17: Does the machine come with a bag?

      All Apex machines purchased with or without a humidifier are provided with a high quality padded bag to carry and store your machine safely.  There is also room for your tubing, power supply and mask.

    • Q18: Do I need a prescription for a CPAP machine?

      Yes.  You must have a prescription for any CPAP machine bought from any supplier.  You should never buy a machine from anyone who is offering to sell you a machine without one.

    • Q19: What are the possible causes for the unit to be noisy?

      While our CPAP machines are very quiet (28 dBA), there are many factors involved when dealing with the perception of sound which is a unique experience for each person. While it is always your right to take the device in to your provider, before you get to that step there may be a few things you can do to isolate and therefore eliminate the sounds.

      In our experience, the most common whistling or other high pitched sounds are caused by small leaks which allow air to escape. Very often these sounds are caused by dust/clogged filters, mask fit, sticky mask valves, or connections that may be loose. Before returning the unit to your provider, please take these steps as they may help in solving the issue. 

      Check Filter on the back of the unit.  Check for dirt or clogging as both conditions can cause noises.  You may need to wash or replace the filter if necessary. 

      Mask Fit/Sticky mask valves- Most of the noise you hear is actually air travelling through your hose and flowing into and out of the mask.  To isolate if this is where the noise may be originating from, disconnect the tubing from the mask inspect the surface for scratches or other physical abnormalities. Secondly, make sure the tubing is firmly connected to the mask inlet and breathe normally. Since sounds can be amplified when fully connected, pay close attention to see if you still detect the sound (even if minor).  If so, you may need to:

      Wash the mask and tubing very thoroughly in warm water, then allow to air dry and repeat the test. In many cases a slightly sticky valve in the mask assembly will cause a whistling sound.

      Try on a different mask (if available). This may help give you different sounds to compare and help in isolating any whistling. 

      Once you have checked the above and the issue has not been resolved, we recommend completing the following breathing cycle. Placing the mask on your face and turning the unit on: inhale, pause (with lungs inflated) for 1-2 seconds, exhale, pause (with lungs deflated) for 1-2 seconds. Taking note of any sounds, repeat the process a few times. Now breathe normally.

      If the sound only appears at one specific part of the breathing cycle, it is more likely that you have a small leak. You will need to reposition the mask on your face or make minor adjustments, such as tightening it slightly. After adjusting the fit of your mask, repeat the breathing cycle test.  Please ensure that this is done while still hooked up to your machine.

      If the sound only appears in the breaks during the breathing cycle and you have verified all connections are secure, please take the unit in to your provider for evaluation.

  • WiZARD Series

    • Q1: How should I clean my mask? 

      Hand-wash all parts with mild soap or diluted dishwashing detergent and warm water (30°C).
      Use a bristle brush to clean the air vents.
      Leave to air dry before re-assembling.

      Do not use bleach, chlorine, alcohol, scented oils or aromatic based solutions. Do not iron the headgear.
      These solutions may cause damage and reduce the life of the product.
      Store the mask system or tubing in a dry place out of direct sunlight.
      Inspect the mask for damage or wear. If any visible deterioration of a component is apparent (cracking, tears, etc.) the component should be discarded and replaced.

      It is not necessary to remove the buckles from the headgear. 

    • Q2: How do I know I have the correct mask size?

      If you have to adjust the headgear so tight that it hurts it probably means you have an incorrectly fitted mask. When using APEX WiZARD mask, it is important not to over-tighten the mask system. If you can only get a good seal by over tightening the headgear, you probably have the wrong size cushion or wrong forehead pad height.

    • Q3: If the electricity goes off while I sleep, will I be able to breathe through my full face mask?

      Yes. APEX WiZARD Full Face Masks have an anti-asphyxia valve that opens if your CPAP device loses power. This feature allows you to breathe in the event of a power failure.

    • Q4: My mask is leakage. What does this mean?

      This may indicate one of the following:

      • incorrect fitting
      • incorrect adjustment
      • incorrect assembly
      • incorrect size
      • mask is worn out and needs replacement 

    • Q5: Can I buy individual replacement mask components like cushions, headgears and short tube?

      Yes. All APEX WiZARD mask components can be purchased separately through an accredited APEX distributor. 

    • Q6: Do I need a prescription to buy a mask?

      Yes.  You must have a prescription to buy a mask.  However, it is possible to purchase mask components separately without a prescription.
