Treatment options in Cheyne-Stokes respiration

Therapeutic Advances in Respiratory Disease, 2010
About half of the patients suffering from heart failure present with sleep-disordered breathing. In most cases obstructive and central breathing disturbances (including Cheyne-Stokes respiration [CSR]) coexist.

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

Clinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...

Testing preload responsiveness by the tidal volume challenge assessed by the plethysmographic perfusion index

Abstract Background To detect preload responsiveness in patients ventilated with a tidal volume (Vt) at 6 mL/kg, the Vt challenge consists in increasing Vt from 6 to 8 mL/kg and measuring the induced increase in pulse pressure variation (PPV). However, this requires an arterial catheter.

Predicting Fluid Responsiveness Using Pulse Pressure Variation after Tidal Volume Challenge in Postoperative Patients Receiving Lung Protective Ventilation: A Clinical Trial [PDF]

, 2019
Abstract Background: Lung protective ventilation with low tidal volume is beneficial in patients with intermediate to high risk of postoperative pulmonary complications. However, during low tidal volume ventilation, pulse pressure variation (PPV) and stroke volume variation (SVV) do not predict fluid responsiveness.

Synergistic Regulation of Hierarchical Anode Interphase and Cathode Electronic Structure by a Fe(III) Complex for High‐Performance Aqueous Zinc‐Manganese Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The NGB additive can concurrently address anode and cathode issues during Zn‐Mn battery cycling by constructing a hierarchical interfacial layer on the anode surface to alleviate side reactions and modulate zinc deposition and by incorporating Fe3+ ions into the α‐MnO2 cathode to improve its structural stability and electrical conductivity.

Volume-controlled ventilation versus pressure-controlled ventilation during laparoscopic surgeries in Trendelenburg position: A randomized comparative study

Asian Journal of Medical Sciences
Background: Laparoscopic surgeries in the Trendelenburg position challenge respiratory mechanics due to pneumoperitoneum and positional effects, increasing airway pressures, and reducing lung compliance. Aims and Objectives: This study compared volume-
