These sleep apnea machines have a similar working principle with CPAPs, but they are less utilized. The mechanical ventilators:
can be used to assist breathing during sleep by people with central apnea.
it treats sleep apnea by rhythmically pushing air into the airway through a tube (positive pressure) or by lowering the air pressure in rhythmic way (negative pressure).
negative pressure ventilators are bigger than positive pressure ventilator. Their operation is based on the pressure around the body. When the pressure drops, the lungs expand and the air flows into them.
Did you know that the air tube often enters the body by a direct small opening of the throat? This is called tracheostomy and you can find more about it at sleep apnea surgery.
Bi-level Positive Airway Pressure (Bi-PAP):
BiPAP can be a more comfortable breathing machine than CPAP. Some advantages of this machine are:
provides two pressure levels, one during inhalation and a lower one during exhalation.
the air is delivered by a nasal mask or face mask.
are used in older children and in infants as well.
Bi-level machines may be used when patients report difficulty with exhaling against positive airway pressure. Bi-level systems allow independent adjustment of inspiratory and expiratory pressure.
the bi-level systems are more expensive and evidence is lacking in terms of better adherence and treatment outcomes when compared with CPAP.
BiPAP devices are adequate for nocturnal ventilation and may improve blood oxygen level.

The APAP machine is the most complicated sleep apnea machine, but it can deliver the best treatment for severe apnea disorders:
Autotitrating CPAP, or auto-CPAP, adjusts CPAP throughout the night by detection of airway flow, snoring, apneas, inspiratory flow limitation, and airway vibration (snoring)
Currently auto-CPAP devices are used in patient homes as treatment or the sleep laboratory to determine the ideal CPAP setting to be used at home by the patient’s conventional fixed-pressure CPAP unit.
Popularity for their use is growing among patients and physicians since the auto-CPAP units can be used to evaluate patients who are having difficulty tolerating conventional CPAP.
The auto-CPAP devices can determine the optimal CPAP setting,quantify a mask leak, and measure patient adherence.

What is an Auto-CPAP?
Special Oral Appliances for sleep apnea
if you have mild sleep apnea or snore very loudly, your doctor may recommend oral appliances.
the mouthpiece will adjust your lower jaw and tongue to help keep the airway in your throat more open while you are sleeping. The air will flow easily into your lungs.
