Der Einfluss unterschiedlichen PEEP-Niveaus (PEEP 5 versus PEEP 10 cm H2O) bei kontrollierter Beatmung und druckunterstützter Spontanatmung auf die Zytokinliberation beim induzierten Lungenversagen
… by increasing positive endexspiratory pressure ( PEEP). Lung protective ventilation is accepted as a proven therapy and the use of ideal PEEP as well as spontaneous breathing during controlled ventilation are common therapy. One of the underlying mechanisms is the biotrauma, an inflammatory …

Automated Detection of Incomplete Exhalation as an Indirect Detection of Auto-PEEP on Mechanically Ventilated Adults
<p>Auto-PEEP is auto positive end-expiratory pressure due to excessive amounts of alveolar gas produced by sustained recurrent incomplete exhalation. Incomplete exhalation occurs when the exhaled breath never reaches a flow rate of 0 L/min. The objective of this dissertation is to develop an …

Der Einfluss von spontanen Atemexkursionen unter druckunterstützter Spontanatmung auf Hämodynamik, Gasaustausch und pulmonale Ventilations-Perfusions-Verteilung beim induzierten akuten Lungenversagen
… ml/kg, peak airway pressures of 35 cm H2O and a PEEP between 5 and 20 cm H2O is important. The choice of the ideal PEEP depends on the best possible gas exchange parameters, respectively on the pressure-volume-curve of the lung. However, spontaneous breathing patterns like BIPAP also show …

Impacto de diferentes métodos de titulação da pressão positiva expiratória final em desfechos clínicos, fisiológicos e segurança de pacientes com insuficiência respiratória aguda associada a COVID-19
… titulação da pressão positiva expiratória final (PEEP) são utilizados para melhorar a oxigenação em pacientes com insuficiência respiratória hipoxêmica por COVID-19. Considerando a existência de diferentes métodos de titulação da PEEP, sem evidências de superioridade entre estes, o objetivo geral …

Ein Vergeich mehrerer Strategien alveolärer Rekrutierung am Modell der isoliert perfundierten Kaninchenlunge
… von der Höhe des eingestellten PEEP abhängt auf dessen Niveau im Anschluss weiter beatmet wird. Weiterhin sollte geklärt werden, ob durch eine solche Beatmungsstrategie PEEP "eingespart" werden kann. Die Untersuchung erfolgte am Modell der isoliert perfundierten Lunge. <br>Es hat …

Influence of tidal volume on pulmonary gas exchange during general anaesthesia
… (VT), or normal tidal volume with and without PEEP. Methods: Prospective, randomised, clinical studies. ASA І and II abdominal surgery patients were randomly assigned to be ventilated with normal VT (NVT) with and without PEEP to 10 cmH2O or with increased VT (IVT) achieved by increasing …

The design and implementation of a language environment for evaluating the programming task
… is an interactive language environment called PEEP. Its base language is Pascal and its design is based on Johnston's semantic models of computation. Storage representations and implementation of these semantic models are described. These models depicting the compile-time structure, run-time …

CRITICALLY ILL PATIENTS WITH COVID-19 PNEUMONIA: PATHOPHYSIOLOGY, IMPACT OF VACCINE, AND CLINICAL OUTCOME.
… (FiO2) and positive end-expiratory pressure (PEEP) on gas exchange in mechanically ventilated patients with ARDS due to COVID-19. Two FiO2 (100% and 40%) were tested at 3 decreasing levels of PEEP (15, 10, and 5 cmH2O). In the fourteen enrolled patients, PEEP of 15 cmH2O, despite resulting in …

Lung mechanics in the aging lung and in acute lung injury. Studies based on sinusoidal flow modulation.
… levels of positive end-expiratory pressure (PEEP) give information about lung collapse and re-expansion. Methods based on flow interruption for measurement of Pel/V curves have limitations due to continuing gas exchange, the need for disconnection from the ventilator or the fact that they are …

EFFECTS OF ARTIFICIALLY - INDUCED INTRINSIC POSITIVE END - EXPIRATORY PRESSURE IN MECHANICALLY VENTILATED PATIENTS WITH ACUTE RESPIRATORY FAILURE.
… of external positive end-expiratory pressure (PEEPe), mechanical ventilation artificially inducing intrinsic PEEP (PEEPi) worsens arterial oxygen tension (PaO2) by causing a less homogeneous distribution of inspired gas, even if tidal volume (Vt), respiratory rate (RR) and total PEEP (PEEPtot) …

The vocal repertoire of Hyla crucifer
… requirements for production of the tapered call, peep and trill were calculated and the trill was found to have a much lower energy outlay than the other calls. The implications of the lower energy expenditure in a trill are considered, and the possibility of two calls in the H. crucifer …

The effects of augmented virtuality on presence, workload, and input performance
… to execute them, users have to remove the HMD (“peep”), breaking their sense of presence. How, then, can real-world interactions during HMD usage be facilitated such that presence is damaged as little as possible? Previous work indicates that Augmented Virtuality (AV), a technique that allows the …
