Abstract

Способ диагностики синдрома обструктивного апноэ/гипопноэ сна путем мониторинга амплитуды дыхания носоротового потока на базовом уровне и во время сна и уровня сатурации крови кислородом на базовом уровне, регистрации эпизодов апноэ и гипопноэ, определения индекса апноэ/гипопноэ и установления по его величине степени тяжести заболевания, отличающийся тем, что регистрируют уменьшение амплитуды дыхательного потока на 90% и более от базового уровня, длительностью 10 с и более, в качестве эпизода апноэ, уменьшение амплитуды дыхательного потока на 30% и более от базового уровня, длительностью 10 с и более, сопровождающееся десатурацией 4% и более, в качестве эпизода гипопноэ, а эпизод гипопноэ без десатурации регистрируют при уменьшении амплитуды дыхательного потока на 30% и более от базового уровня длительностью 10 с и более без десатурации, после чего по сумме эпизодов апноэ, гипопноэ и гипопноэ без десатурации определяют индекс апноэ/гипопноэ.A method for diagnosing obstructive sleep apnea / hypopnea syndrome by monitoring the amplitude of breathing of the nasal cavity flow at the basic level and during sleep and the level of blood oxygen saturation at the basic level, recording episodes of apnea and hypopnea, determining the apnea / hypopnea index and determining the degree of disease severity from it characterized in that a decrease in the amplitude of the respiratory flow by 90% or more from the baseline, lasting 10 seconds or more, as a episode of apnea, a decrease in the amplitude of the respiratory sweat is recorded eye 30% or more of the baseline, lasting 10 seconds or more, accompanied by desaturation of 4% or more, as an episode of hypopnea, and an episode of hypopnea without desaturation is recorded with a decrease in the amplitude of the respiratory flow by 30% or more from the baseline for 10 seconds and more without desaturation, after which the apnea / hypopnea index is determined by the sum of the episodes of apnea, hypopnea and hypopnea without desaturation.

Claims

A method for diagnosing obstructive sleep apnea / hypopnea syndrome by monitoring the amplitude of breathing of the nasal cavity flow at the basic level and during sleep and the level of blood oxygen saturation at the basic level, recording episodes of apnea and hypopnea, determining the apnea / hypopnea index and determining the degree of disease severity from it characterized in that a decrease in the amplitude of the respiratory flow by 90% or more from the baseline, lasting 10 seconds or more, as a episode of apnea, a decrease in the amplitude of the respiratory sweat is recorded eye 30% or more of the baseline, lasting 10 seconds or more, accompanied by desaturation of 4% or more, as an episode of hypopnea, and an episode of hypopnea without desaturation is recorded with a decrease in the amplitude of the respiratory flow by 30% or more from the baseline for 10 seconds and more without desaturation, after which the apnea / hypopnea index is determined by the sum of the episodes of apnea, hypopnea and hypopnea without desaturation.
