apnea may first be diagnosed in childhood, and it is recommended to consult an ent specialist, allergist or sleep physician to discuss symptoms when noticed; malformation and/or malfunctioning of the upper airways may be observed by an orthodontist.  the reason for the tor time limit of voluntary apnea is that the rate of breathing and the volume of each breath are tightly regulated to maintain constant values of co2 tension and ph of the blood more than oxygen levels. some have incorrectly attributed the effect of hyperventilation to increased oxygen in the blood, not realizing that it is actually due to a decrease in co2 in the blood and lungs.
because the exchange of gases between the blood and airspace of the lungs is independent of the movement of gas to and from the lungs, enough oxygen can be delivered to the circulation even if a person is apneic, even if the diaphragm doesn’t move. with the airways closed or obstructed, this will lead to a gradual collapse of the lungs and suffocation. it can be employed to provide a sufficient amount of oxygen in thoracic surgery when apnea cannot be avoided, and during manipulations of the airways such as bronchoscopy, intubation, and surgery of the upper airways. in this situation a confirmatory test is warranted as it is unsafe to perform the apnea test to the patient.

although respiratory rate may appear to only measure the number of breaths per minute, it also serves to measure the health of bodily processes that are involved in breathing. sleep apnea is a breathing disorder that causes people’s breathing to slow and stop for brief periods while they are asleep. people may also experience a low respiratory rate while asleep for reasons unrelated to a sleep disorder. however, the low respiratory rate associated with sleep apnea can cause people to experience excessive daytime sleepiness, loud snoring, morning headaches, and a decrease in concentration. they will be able to determine whether your breathing rate is cause for concern and discover any disorder that may be causing your symptoms. dr. singh is the medical director of the indiana sleep center. dr. singh is the medical director of the indiana sleep center.
sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. if you snore loudly and feel tired even apnea (bre: apnoea) is the temporal cessation of breathing. during apnea, there is no movement of the muscles of inhalation, and the volume of the lungs during an apneic episode, the diaphragm and chest muscles work harder as the pressure increases to open the airway. breathing usually resumes, .
