Anyone having sleep apnea may experience air obstruction of a different level. Therefore, it is essential to have your own CPAP device set, for your ideal level as per your needs.
This can ensure that you will breathe easily all night, and while you wake up in the morning, you will be fully refreshed and ready for the next day.
CPAP masks used for ensuring your Continuous Positive Airway Pressure remain controlled so that your breathing will not get obstructed during the night by applying continuously air pressure through the mouth or your nose. With this, common treatment for Obstructive Sleep Apnoea is provided.
If you leave it untreated, then your airway will become obstructed or may even collapse too while sleeping, because of position of your throat or tongue tissue. With the application of positive airway pressure, it can help to address this issue by keeping airway open and help in reducing the incidence of you gasping for air and remain awake all throughout the night.
What we mean by CPAP pressure settings?
The basic key is to making sure that your device setting for CPAP are suitable for only your specific condition.
In case, of majority of people, appropriate CPAP pressure will be between 6 to 14 cmH2O, while the average is 10 cmH2O. What your exact specific level will be will be determined by your sleep specialist.
Also, it is very important to note, over a period of time, pressure of your CPAP device may require adjusting. As an example, in case you start to snore while using CPAP device, this may indicate that present level is not right for you, which need to be properly checked.
Determining CPAP pressure
In order to determine CPAP setting, as part of overnight titration study within a lab, polysomnography technologist will generally observe your breathing patterns and then adjust your setting upwards as you sleep. It will be done remotely from some other room to avoid any disturbances.
The main objective is to eliminate your snoring and sleep apnea to observe deep sleep, which also includes rapid eye movement sleep. Setting should be optimized while you sleep on your back, as sleep apnea worsens in this position.
Few people are often sent home with self-adjusting CPAP machine, which is called as Auto CPAP or APAP. The prescribing physician in such scenario allows range of pressures.
Initially, the machine will begin from low and slowly adjust upwards as required in response to the measured airway resistance.
The CPAP will deliver intermittent extra air pressure pulses to evaluate for any resistance, whether upper airway will be collapsing. In case airway is open with present CPAP setting, then it will be maintained.
Your required CPAP pressure may not correlate directly with severity of your sleep apnea. Few people having mild OSA may need higher pressures and few people having severe OSA may need modest pressures.
Those with more severe kind of sleep apnea often need higher amount of pressures on CPAP. Especially this is true for the obesity setting or nasal obstruction. Even children may need similar pressures like adults, despite having smaller size in their airways.
