Journal ArticleDOI
Oximeter-Based Autonomic State Indicator Algorithm for Cardiovascular Risk Assessment
TL;DR: Signals derived from overnight oximetry recording provide a novel potential tool for CV risk classification and Prospective studies are warranted to establish the value of the ASI algorithm for prediction of outcome in CV disease.
Journal ArticleDOI
Detection of sleep disordered breathing and its central/obstructive character using nasal cannula and finger pulse oximeter.
TL;DR: Automatic analysis based on routine pulse oximetry alone may be used to detect sleep disordered breathing with accuracy and the combination of photoplethysmographic signals with a nasal flow signal provides an accurate distinction between obstructive and central apneic events during sleep.
Journal ArticleDOI
Detection of cardiovascular risk from a photoplethysmographic signal using a matching pursuit algorithm
Dirk Sommermeyer,Ding Zou,Joachim H. Ficker,Winfried Randerath,Christoph Fischer,Christoph Fischer,Thomas Penzel,Bernd Sanner,Jan Hedner,Ludger Grote +9 more
TL;DR: The developed algorithm extracts meaningful parameters indicative of cardiorespiratory and autonomic nervous system function and dysfunction in patients suspected of SDB in patients referred for a sleep study with suspected sleep apnea.
Journal ArticleDOI
The use of overnight pulse wave analysis for recognition of cardiovascular risk factors and risk: a multicentric evaluation
Dirk Sommermeyer,Ding Zou,Derek N. Eder,Jan Hedner,Joachim H. Ficker,Winfried Randerath,Christina Priegnitz,Thomas Penzel,Ingo Fietze,Bernd Sanner,Ludger Grote +10 more
TL;DR: In this article, the authors evaluated an algorithm on the basis of a photoplethysmographic pulse wave recording during sleep for cardiovasc for risk stratification of cardiovascular disease.
Journal ArticleDOI
REM Sleep Imposes a Vascular Load in COPD Patients Independent of Sleep Apnea.
Ludger Grote,Dirk Sommermeyer,Joachim H. Ficker,Winfried Randerath,Thomas Penzel,Ingo Fietze,Bernd Sanner,Jan Hedner,Hartmut Schneider +8 more
TL;DR: In contrast to healthy controls, REM sleep imposes a vascular load in COPD patients independent of sleep apnea indices, intermittent and sustained hypoxia and REM sleep modulate arterial stiffness.
