Central Sleep Apnea Graph

Sleep experts report that the great majority of central apnea patients also experience obstructive sleep apnea although the csa may not be noted until the osa is treated. Csa is usually due to an instability in the body s feedback mechanisms that control respiration.

This occurs because the brain temporarily stops signaling the respiratory muscles to breathe.

Central sleep apnea graph. Central sleep apnea is a condition that causes short pauses in a person s breathing as they sleep. Central sleep apnea can be caused by a number of conditions that affect the ability of your brainstem which links your brain to your spinal cord and controls many functions such as heart rate and breathing to control your breathing. Central sleep apnea occurs when your brain fails to transmit signals to your breathing muscles.

1 this condition is in contrast to obstructive sleep apnea osa in which ongoing respiratory effort is present during respiratory events. Whereas osa is extremely common in the adult population central sleep apnea csa affects less than 10 of patients referred to sleep laboratories. In some cases the sleeping csa patient displays not a periodic failure to breathe at all but a periodic shallow breathing or underbreathing that alternates with deep overbreathing a condition known as cheyne stokes breathing.

As opposed to obstructive sleep apnea osa central sleep apnea is characterized by repetitive cessation of ventilation during sleep resulting from lack of ventilatory effort or drive to breathe. Obstructive sleep apnea explained clearly pathophysiology diagnosis treatment duration. Central sleep apnea csa or central sleep apnea syndrome csas is a sleep related disorder in which the effort to breathe is diminished or absent typically for 10 to 30 seconds either intermittently or in cycles and is usually associated with a reduction in blood oxygen saturation.

In contrast to obstructive sleep apnea osa in which ongoing respiratory efforts are observed central apnea is defined by a lack of respiratory effort during cessations of airflow.

Central sleep apnea csa is defined by the cessation of air flow without respiratory effort. Central sleep apnea csa is characterized by a lack of drive to breathe during sleep resulting in insufficient or absent ventilation and compromised gas exchange.
