What are CPAP machines and APAP machines?

CPAP machines and APAP machines are very efficient ways in treating and managing sleep apnea, other sleep disorders and respiratory illnesses. CPAP stands for continuous positive airway pressure and APAP stands for automatically adjusting positive airway pressure.

What are the differences between CPAP mahines and APAP machines?

As you can see the first difference from CPAP vs APAP machines is that the CPAP machines offer one steady airway pressure while the APAP machines have airway pressure that is adjusted automatically based on the breathing of the sleep apnea patient.

With the CPAP machines your doctor will set the machine to offer the amount of airway pressure they have deemed is necessary to manage your sleep apnea, other sleep disorder and respiratory illnesses. With the APAP machines a recording device or recording software with the machine track how much airway pressure you need and will adjust based on your needs.

Why do patients choose either a CPAP machine or an APAP machine?

Generally patients who have many changes in their breathing issues during sleep will opt for the APAP machines to treat and manage their disorder or illness. Other patients who have had the same continuous issues over time have opted for the CPAP machines. Some patients generally just do very well with the continuous airway pressure from the CPAP machines. There are also some patients who start with a CPAP machine and that airflow does not help to manage their symptoms enough so they are switched to an APAP machine.

CPAP vs APAP: Ratings and More

There are many CPAP machines out there however my team and I have practically tested them all and complied a list of the best CPAP Machines.

  • Sound Level: 90/100
  • Pressure Features: 90/100
  • Data Capabilities: 90/100
  • Unique Features: 85/100
  • Ease of Use: 90/100
  • Overall: 90/100

As you can tell from above CPAP machines do have high ratings however sometimes CPAP machines are not efficient in treating and managing some patients disorders or illnesses.

Both the CPAP machines and the APAP machines have pros about them. Here we can compare them both to see them side by side. Some of the CPAP machines have the following pros.

  • Mostly Quiet Machines
  • Good Data Capabilities
  • Easy Use for Most of These Machines
  • Good Setup on Some of These Machines
  • Good Humidity Control
  • Protection From Water Damage
  • Some Have Heated Tubing Options
  • Small Size/Lightweight
  • Some Have an SD Card for Storage of the Data

APAP machines also have many benefits which include the following:

  • Provide Two Machines in One (CPAP Mode or Auto Adjusting Mode)
  • Allows For Increased Pressure Needs
  • Allows For Changing Pressure for Different Sleeping Positions
  • Automatically Adjusts Pressure When Mask Is Changed
  • Allows For Better Compliance Than Most CPAP Machines
  • Self-Titration

What are the cons of the CPAP machines and the APAP machines?

As with all other types of treatment for sleep apnea, other sleep disorders and respiratory illnesses there are cons involved. Some of the cons of CPAP machines are:

  • Heavier Than Most BiPap machines
  • Some Noise Complaints of These Machines
  • Not As Much Exhalation Relief as Many BiPap machines
  • Some Reports of Incorrect Data Reported
  • Some of These Machines Do Not Have the Easiest to Understand Manuals
  • The Air Flow on These Machines Is Not As Great As The Air Flow On The BiPap Machines
  • Some Complaints About The Heated Tubing Options

These cons do not outweigh all of the great benefits above. In addition, the APAP machines also have some cons such as:

  • Too Many Pressure Changes For Some Patients
  • Very Few Patients Reported Uncomfortable Pressure Changes
  • Some Patients Reported The Data Was Difficult to Understand

Even with these few cons APAP machines have been rated very highly by many patients.

Summary of CPAP vs APAP Machines

CPAP machines and APAP machines are very effective treatments for sleep apnea, other sleep disorders and respiratory illnesses. If you are one of these patients check out different CPAP machines and APAP machines today. Click here to find out the differences between CPAPs and BiPAP machines as well. CPAP machines work perfectly for the majority of people that are diagnosed with sleep apnea. The biggest downside to APAP machines are that they cost more money. If you do not need an APAP machine, a CPAP machine will definitely suffice.

I also recommend that you pick up a CPAP cleaner such as the SoClean 2 because the tubes, masks and machines get pretty dirty with frequent use.
