Sometimes airways are obstructed at least partly due to certain facial and oral structures, like a recessed jaw or large tongue, that make it harder for CPAP alone to open the airway enough, even ...
CPAP machines possess a motor that pressurizes room temperature air and delivers it through a hose connected to a mask or tube worn by the patient. This constant stream of air opens and keeps the upper airway unobstructed during inhalation and exhalation. [1] Some CPAP machines have other features as well, such as heated humidifiers.
The titrated pressure is the pressure of air at which most (if not all) apneas and hypopneas have been prevented, and it is usually measured in centimetres of water (cm H 2 O). The pressure required by most patients with sleep apnea ranges between 6 and 14 cm H 2 O. A typical CPAP machine can deliver pressures between 4 and 20 cm H 2 O.
Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial obstruction of the upper airway leading to reduced or absent breathing during sleep.
The conditions of hypoxia and hypercapnia, whether caused by apnea or not, trigger additional effects on the body.The immediate effects of central sleep apnea on the body depend on how long the failure to breathe endures, how short is the interval between failures to breathe, and the presence or absence of independent conditions whose effects amplify those of an apneic episode.
Blood leaving the lungs is normally fully saturated with oxygen, so hyperventilation of normal air cannot increase the amount of oxygen available, as oxygen in blood is the direct factor. Lowering the CO 2 concentration increases the pH of the blood, thus increasing the time before blood becomes acidic enough so the respiratory center becomes ...
