Obstructive sleep apnoea (OSA) is the major sleep disorder prevalent in 3 to 7% of adult men and 2 to 5% of adult women in the general population. Given all the risk factors like obesity and high neck circumference, male gender, and the older man, and others, you may have OSA that contributes to severe consequences like hypertension, heart disease, stroke, diabetes, etc.

The gold standard treatment which is proven for OSA is PAP therapy which is used during sleep. It gives positively pressurized air through a device called CPAP (Continuous positive airway pressure) which is connected to a patient with a mask via tube. This pressure keeps the airway patent and opens during sleep thus helping to stop snoring, maintaining the oxygen level, and reducing the frequent arousals due to choking or apnoea. This in return improves the daytime symptoms of fatigue, laziness, excessive daytime sleepiness, and anxiety by maintaining the daytime energy.


PAP NAP as the name suggests is a daytime trial of CPAP for making you adjust to the mask and the therapy.


As the saying goes “Practice makes the man perfect.”

Though the efficiency of CPAP therapy is proven and known, adherence to CPAP therapy is very low. PAP NAP is the supervised daytime trial with the mask and the device to make you comfortable with the interface, pressures, and a new lifestyle change and eradicate all your fears, doubts, and quarries.

This will improve the tolerance to the sleep apnoea treatment and subsequently improves the overall compliance. The therapist counsel and make you comfortable with the mask and the pressure by keeping you under close observation in the daytime while you take a nap for 30 min to 1 hour or more as required so that you can use it better at night while sleeping for more than 4 hours.


After going through the sleep study test, if you are diagnosed with moderate to severe obstructive sleep apnoea, you must go for CPAP therapy. Since this therapy is meant for a long term use, it’s really important for you to get adjusted to the pressure and mask, resolve your doubts regarding your issues like nose blockage, mouth dryness, claustrophobia, settings adjustment according to your need and make you comfortable with the new adjunct in your life for better compliance and sleep.

It also supports you emotionally and physically, to divert your attention from mask and pressure by giving you a daytime nap of 100 minutes.


PAP NAP includes 5 components:

  1. Pre-test instructions to help patients take daytime naps with ease. Instructions on how to prepare for the test, like avoiding caffeine, nighttime sleep restrictions, and providing a ride to a sleep centre to avoid driving.
  2. Introduction of PAP therapy and barrier assessmentYou are given a brief idea of how the mask and pressure would feel and how to manage your fears about it and then they are assisted to try different types of masks according to your comfort and need. The mask fitting and the feel of pressure are given to you in a sitting position and you are asked to breathe normally coordinating with the air pressure coming through the mask. Once you are comfortable with the mask, you are made to lie down and try taking a nap in your usual position of sleep except for the prone position.
  3. Emotional supportTalk about the fear, anxiety, stress, and other issues like how would the spouse react to it and the embarrassment of using a mask to sleep. All these issues are addressed one by one by the sleep therapist and reduce the anxiety. Since it’s done during regular working hours, any sudden reaction and problem can be immediately attended to and resolved by the sleep therapist.
  4. PAP NAP is conducted between 60– and 120 minutes. The primary goal is to allow you to get comfortable with the therapy and not to really do the titration part. You may or may not fall asleep but you will be able to figure out if you feel comfortable sleeping with the mask and pressure or not.
  5. Post-test follow-upDiscussion about the PAP therapy preliminary results, motivation, adherence, and usage is then elaborated on and explained in detail on how to use the device, how to get used to it by taking daytime trials with it, how to overcome any issues related to it like bloating, mouth dryness, leakage, pressure sores, and cleaning process is done.
