A hipoxemia relacionada ao sono central devida a condição médica é caracterizada por declínio sustentado da SpO2 (saturação de oxigênio medida por oximetria de pulso) (≤ 88% no adulto e ≤ 90% na criança por período ≥ 5 minutos) durante o sono. A condição é atribuível a condição médica ou neurológica. A presença da hipoxemia não é melhor explicada por outro transtorno respiratório relacionado ao sono (p.ex., apneia obstrutiva do sono). Embora algum grau de apneia obstrutiva ou central possa estar presente, estes transtornos não são considerados como a causa primária da hipoxemia durante o sono. Alguns pacientes com hipoxemia relacionada ao sono exibem também hipoxemia quando acordados.

Sleep related hypoxemia due to a medical condition is characterised by sustained declines in SpO2 (oxygen saturation measured by pulse oximeter) (≤ 88% in adults or ≤ 90% in children for ≥ 5 minutes) during sleep. The condition is attributable to a medical or neurological disorder. The presence of hypoxemia is not better explained by another sleep related breathing disorder (e.g., obstructive sleep apnoea). Although some amount of obstructive or central apnoea may be present, these disorders are not thought to be primarily responsible for the hypoxemia during sleep. Some patients with sleep related hypoxemia also exhibit hypoxemia during wakefulness. If the presence of hypercapnia has been established, a diagnosis of sleep-related hypoventilation should be made, rather than sleep-related hypoxemia. Note: A definitive diagnosis requires objective evidence based on polysomnographic monitoring of oxygen saturation in arterial blood (SaO2) in the presence of a medical condition that is judged to be causing the declines in SaO2. |
