Which Z1 Travel CPAP machine will work for me?

Deciding which Z1 Travel CPAP to purchase ultimately comes down to a question of whether you are better suited for a traditional CPAP or auto-adjusting CPAP device.

Auto-adjusting devices (sometimes referred to as APAP devices) like the Z1 Auto are recommended to patients whose pressure needs may change during the night. You may have fluctuating pressure needs if any of the following apply:

  • You change positions a lot. You may be better suited to an auto-adjusting CPAP if you tend to shift positions during the night. This is because you generally require a higher amount of pressure when you’re lying on your back versus your side.
  • You drink alcohol or take certain medications. Alcohol and sedative medications can influence your pressure needs. You may want to consider an auto-adjusting CPAP machine if you drink or take certain prescription drugs.
  • You have seasonal allergies. If you have seasonal allergies, you are likely to need higher pressure levels during times of nights or seasons when you are more congested.

If you are unsure of whether a fixed-pressure or auto-adjusting CPAP machine will work best for you, consult with your doctor.
