Summary of "AASM Criteria for Scoring Respiratory Events: Interaction between Apnea Sensor and Hypopnea Definition."

To examine the impact of using a nasal pressure sensor only vs the American Academy of Sleep Medicine (AASM) recommended combination of thermal and nasal pressure sensors on (1) the apnea index (AI), (2) the apnea-hypopnea index (AHI), where the AHI is calculated using both AASM definitions of hypopnea, and (3) the accuracy of a diagnosis of obstructive sleep apnea (OSA).

The 2012 AASM Respiratory Event Criteria Increase the Incidence of Hypopneas in an Adult Sleep Center Population.

To investigate the effect of the 2012 American Academy of Sleep Medicine (AASM) respiratory event criteria on severity and prevalence of obstructive sleep apnea (OSA) relative to previous respiratory ...

Scoring Tools for the Analysis of Infant Respiratory Inductive Plethysmography Signals.

Infants recovering from anesthesia are at risk of life threatening Postoperative Apnea (POA). POA events are rare, and so the study of POA requires the analysis of long cardiorespiratory records. Manu...

Patients with STOP-BANG score >3 have a high risk of Obstructive sleep apnea. The aim of this study was to evaluate early postoperative respiratory complications in adults with STOP-BANG score >3 afte...

Postoperative Sleep-Disordered Breathing in Patients Without Preoperative Sleep Apnea.

Recently published data show that postoperative apnea-hypopnea index (AHI) is significantly increased in some patients without preoperative sleep apnea. These patients may be at risk of developing per...

Counterpoint: Is the AHI the best way to quantify the severity of sleep disordered breathing? No.

Since the early clinical descriptions of obstructive sleep apnea in the 1970s, our understanding of the pathogenesis and adverse consequences of this chronic disease has advanced substantially. Initia...

Vasoactive Hormones and Oxygen Saturation During Apneic Events in Patients With Obstructive Sleep Apnea

The mechanisms involved in development and maintenance of hypertension in obstructive sleep apnea are not clarified. We hypothesize that patients with obstructive sleep apnea have an abno...

Medical and Biotech [MESH] Definitions

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)

Biological actions and events that support the functions of the RESPIRATORY SYSTEM.

A noninvasive diagnostic technique that enables an experienced clinician to perform direct microscopic examination of the surface and architecture of pigmented SKIN lesions. The four major dermoscopic criteria are ABCD: asymmetry (A), borders (B), colors (C), and different structural components (D) providing a semiquantitative scoring system for each lesion.

Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.

An abnormal pattern of breathing characterized by alternating periods of apnea and deep, rapid breathing. The cycle begins with slow, shallow breaths that gradually increase in depth and rate and is then followed by a period of apnea. The period of apnea can last 5 to 30 seconds, then the cycle repeats every 45 seconds to 3 minutes.
