Einfluss der atrialen Überstimulation mit zwei Frequenzen auf nächtliche Atemstörungen
(2012-06-20)Atrial overdrive pacing markedly improved sleep disordered breathing in a recent study. Using a single blinded, randomized, crossover design, we aimed to reproduce these findings and investigate the possible underlying ... -
Evaluierung eines Qualitätssicherungsprogramms im interdisziplinären Fachgebiet am Beispiel der Schlafmedizin
(2012-10-26)Due to short financial resources it is essential to establish quality assurance activities to achieve an optimal medical care quality and improved transparency in medicine. On the one hand quality assurance is required by ... -
Funktionen von Trp53 in der Homöostase des Bronchialepithels und der Kontrolle pulmonaler Entzündungsreaktionen als modellhafte Perspektive auf die COPD
(2021-11-02)The pulmonary epithelia of patients with COPD show an increased expression of TP53 and have higher proliferation and apoptosis rates, compared to healthy individuals. Although, Trp53-deficient mouse lung have higher ... -
Grenzwerte der Mechanical Power für die Entstehung einer akuten beatmungsinduzierten Lungenschädigung
(2023-07-05)Acute respiratory distress syndrome (ARDS) is a life-threatening condition characterized by lung failure. Despite intensive research, ARDS mortality remains high. Mechanical ventilation, often required to allow survical, ... -
Interobserver-Agreement zwischen Pneumologen und dem Zytopathologen, die identische TBNA-Ausstriche bewertet haben
(2020-07-02)Introduction: Cytology has become increasingly important in lung cancer as mediastinal staging via EBUS guided TBNA has virtually replaced mediastinoscopy. The aim of this study was to compare two independent cytological ... -
Langzeit-EIT-Monitoring als Indikator für die Entstehung eines Lungenödems während maschineller Beatmung im Tierexperiment
(2024-02-02)In the present study, the question of the extent to which long-term EIT monitoring (EIT = electrical impedance tomography) is suitable as an indicator for the development of pulmonary oedema during mechanical VILI ventilation ... -
Lokale Phasenkontrast-Computertomographie - eine neue Strategie für die Lungenbildgebung im Menschen
(2023-07-03)This work demonstrates the testing of propagation-based local phase contrast tomography of the lung on a human size scale using clinically clinically acceptable radiation doses. The microstructure of the lung predestines ... -
Der PEEP und seine Auswirkung auf die mechanische Leistung bei der maschinellen Beatmung
(2021-05-11)PEEP in the context of VILI in mechanical ventilation is assumed to be protective. Theoretical PEEP should be a part of the computation of the applied mechanical power as it is proposed in the concept of ergotrauma and ... -
Postoperatives Monitoring der regionalen Lungenventilation durch die Elektrische Impedanztomographie bei Kindern und Jugendlichen mit einem angeborenen Herzfehler
(2012-05-29)The present study investigates the clinical applicability of electrical impedance tomography (EIT) in pediatric patients after cardiac surgery for congenital heart disease on a pediatric intensive care unit. Regional ... -
Prävalenz schlafbezogener Atemstörungen bei Patienten mit Thrombose und Lungenembolie
(2012-07-17)Background: Obstructive sleep apnea is recognized as a risc factor for cardio- and cerebrovascular disease during the last years. The aim was to detect the influence of obstructive sleep apnea on thromboembolic events ... -
Reduzierte Variabilität der Herzfrequenz bei Patienten mit Epilepsie bzw. unter antikonvulsiver Medikation
(2013-08-28)Heart Rate Variability in 152 Patients with Epilepsie or with chronicle pains who received antiepileptic drugs was studied. We used 24 hour ECG, time domaine. There was no significant diffirence between patients and healthy ... -
Über die Prävalenz der Cheyne-Stokes-Atmung bei herzinsuffizienten Patienten unter moderner medikamentöser Therapie
(2012-01-05)The aim of this investigation was to examine the prevalence of Cheyne-Stokes respiration in patients with congestive heart failure and modern medical treatment. In 50 patients (7 female and ... -
Variation des exspiratorischen Umschaltkriteriums während assistierter Beatmung bei chronisch obstruktiver Lungenerkrankung – Untersuchung der Patient-Ventilator-Interaktion am Lungenmodell
(2015-11-10)Introduction: During pressure support ventilation (PSV) the ventilator cycles to the expiratory phase when the inspiratory flow falls below a predefined percentage of the peak-flow, the off-cycling criterion. In COPD ... -
Wirkungen der Bronchodilatation mit Salmeterol auf das autonome Nervensystem
(2015-05-26)Abstract: Neurohumoral activation is present in COPD and might provide a link between pulmonary and systemic effects, especially cardiovascular disease. Because long acting inhaled β-agonists reduce hyperinflation, they ...
