STUDY OBJECTIVES Polysomnography (PSG) is the gold standard in diagnosing sleep disordered breathing (SDB. [] Key MethodSETTING Sleep laboratory. PARTICIPANTS 70 study subjects (28 with obstructive sleep apnea [OSA], 20 with CSR, 11 with CSR+OSA and 11 without SDB). MEASUREMENTS The nasal cannula flow signal was analyzed by ApneaLink (ResMed, Sydney, Australia), based on a classifier algorithm using pattern recognition.

Figures and Tables from this paper

Validation of ApneaLink Ox™ for the diagnosis of obstructive sleep apnea

TLDR
The AHI obtained automatically from the ApneaLink Ox using oxygen desaturation ≥3 % as a criterion of hypopnea had a good performance to diagnose OSA and the manual scoring from Apnea Link Ox™ was better than the automatic scoring to discriminate patients with OSA.

Diagnosis of Sleep-Disordered Breathing in the Home Environment.

TLDR
It is concluded that home diagnosis of OSA is a relatively easy and cost-effective way to substitute for the hospital-linked polysomnography, particularly in severely ill patients who have a movement difficulty.

ResCSRF: Algorithm to Automatically Extract Cheyne–Stokes Respiration Features From Respiratory Signals

TLDR
Results indicate that ResCSRF is capable of automating the scoring of CSR-related features and could potentially be implemented into a remote monitoring system to regularly monitor patients’ cardiac function.

Utility of polygraphic studies for sleep apnea screening in the setting of tertiary care hypertension outpatient clinic

TLDR
The results justify routine polygraphic screening of hypertensive patients requiring tertiary care and suggest that abridged medical history may substantially increase the odds for positive screening.

Indication of CPAP in Patients with Suspected Obstructive Sleep Apnea, Based on Clinical Parameters and a Novel Two-Channel Recording Device (ApneaLink): A Pilot Study

TLDR
This study has shown that the use of ApneaLink plus clinical data has made it possible to indicate CPAP reliably in most patients with high-clinical pretest for OSA.

Evaluation of a single-channel nasal pressure device to assess obstructive sleep apnea risk in laboratory and home environments.

TLDR
The ApneaLink demonstrated good sensitivity and specificity in quantifying AHI when compared to PSG in a population with and without confirmed OSA, and may be useful in de novo large-scale occupational or underserved community OSA diagnostic programs.

Diagnosis of sleep apnea in patients with stable chronic heart failure using a portable sleep test diagnostic device

TLDR
The results suggest that ApneaLink could be used in clinical practice to identify heart failure patients with high and low probability of having sleep apnea, sparing the need for a diagnostic polysomnography and thus potentially impacting prognosis by providing a more cost-effective and timely diagnosis of this non-cardiac comorbidity.

[Validation of microMESAM as screening device for sleep disordered breathing].

TLDR
MicroMESAM-generated flow-time curves correspond well with pneumotachograph generated curves, producing automated AHIs that are highly sensitive in detecting SDB.

Pattern recognition of obstructive sleep apnoea and Cheyne–Stokes respiration

TLDR
It is concluded that the use of an artificial neural network relying on spectral analysis of the airflow could be a useful method as a diagnostic test for obstructive sleep apnoea and Cheyne–Stokes respiration.

Validation of the ApneaLink for the screening of sleep apnea: a novel and simple single-channel recording device.

TLDR
This study demonstrates that the ApneaLink device provides reliable information, is a simple, easy-to-use device, and is highly sensitive and specific in calculating AHI, when compared with the AHI obtained from full polysomnography.

Night-to-night variation of the oxygen desaturation index in sleep apnoea syndrome

TLDR
The findings suggest that the diagnostic accuracy of the MESAM-IV is strong, since the oxygen desaturation index is correlated with the apnoea–hypopnoean index, which is rather small, and screening could be reliably based on single 1-night recordings.

Cheyne-Stokes respiration in stroke: relationship to hypocapnia and occult cardiac dysfunction.

TLDR
In patients with stroke, CSA is associated with hypocapnia and occult LV systolic dysfunction but is not related to the location or type of stroke, and the presence of LV syStolic dysfunction isassociated with a Cheyne-Stokes pattern of hyperpnea.

Measuring agreement between diagnostic devices.

TLDR
A systematic review of portable monitoring research has recently been completed by a joint working group of the American College of Chest Physicians, the American Thoracic Society, and the American Academy of Sleep Medicine.

Increased mortality associated with Cheyne-Stokes respiration in patients with congestive heart failure.

TLDR
It is suggested that CSR itself accelerates the deterioration in cardiac function as well as mortality in patients with congestive heart failure who develop Cheyne-Stokes respiration during sleep.

Cheyne-Stokes respiration and supine dependency

TLDR
Sleep in the supine body position increases the frequency of apnoea and hypopnoeas in patients with Cheyne-Stokes respiration.

Sleep apnea in 81 ambulatory male patients with stable heart failure. Types and their prevalences, consequences, and presentations.

TLDR
Sleep disruption and arterial oxyhemoglobin desaturation were significantly more severe and the prevalence of atrial fibrillation and ventricular arrhythmias were greater in group 2 than in group 1.

Causes of cheyne-stokes respiration

TLDR
Cheyne-Stokes respiration is one of several types of unusual breathing with recurrent apneas (dysrhythmias) and instability in the feedback control involved in the chemical regulation of breathing is the leading cause of CSR.
