Some users report nosebleeds or nasal dryness. Mouth breathers may not get as much benefit from this type of mask because it applies pressurized air only to the nasal passages.
This may be particularly useful in a retrognathic patient with a bulky tongue for example, where the Contudo will bring the jaw forward, improve the retroglossal dimension and therefore reduce CPAP pressure. Further work has demonstrated not only their clinical efficacy but also their cost effectiveness in the long-term, with a suggestion that a MAS is an appropriate first choice in most patients in the short-term (39). Again, however, long-term analysis of cardiovascular risk stratification is deficient, particularly in comparison with CPAP-related studies.
Power socket needed – CPAPs require a nearby power socket, as well as a secure surface to sit on, whereas an EPAP simply sits in the user’s nostrils without being attached to a machine.
Some CPAP units even adjust automatically to patterns in your breathing, increasing or decreasing air pressure throughout the night as needed.
Miscellaneous devices: Other devices have recently been developed as alternative treatments for patients who are unable or to unwilling to use CPAP therapy5,6. Nasal expiratory resistive devices (Provent® by Theravent Inc) are disposable adhesive devices placed over the nostrils. These devices increase resistance during exhalation thereby increasing upper airway patency by maintaining positive pressure in the upper airway prior to inhalation when the upper airway is most likely to collapse.
What are the side effects of CPAP? CPAP treatment is a very safe treatment but it may cause discomfort in some people, such as a dry or stuffy nose, irritation of the skin on your face, and sore eyes due to air leaking around the mask.
The first incision is made under the patient’s chin where here the nerve controlling their tongue is located. A small cuff is placed on this nerve.
Different air pressure systems – CPAP machines send pressurized air into the patient’s airway, and EPAP devices create their own pressure when the user exhales.
Positional therapy: Some patients with OSA, only have significant sleep disordered breathing in the supine position. Thus, some clinicians may prescribe positional therapy to patients with less severe disease whose OSA occurs predominantly in the supine position. This treatment may be achieved though various interventions, such as tennis ball placed in the back of a nightshirt or through more formal devices that have been developed specifically for this purpose.
After a few months of use, patients have a follow-up sleep study to ensure their sleep goals are being met. Once all is confirmed, patients will have check-ins with their sleep physician every seis-12 months at physician discretion.
PAP failure is defined as an inability to eliminate OSA (AHI of greater than 15 despite PAP usage), and PAP intolerance is defined as:
pressure. The pressure stays the same while the patient breathes in and out. It does not change unless the clinician increases or decreases the set pressure.
Is sleep nasendoscopy a valuable adjunct to clinical examination in the evaluation of upper airway obstruction?
It can also cause excessive daytime sleepiness, which may increase safety risks and accidents or simply make it hard to function. Luckily, several treatment options are available to treat sleep apnea.
