Effects of flow‐controlled expiration on oxygenation and early recovery in horses undergoing general anaesthesia

Equine Veterinary Journal, EarlyView.
Abstract Background FLow‐controlled EXpiration (FLEX) has been shown to significantly enhance oxygenation in horses under clinical and experimental conditions. Objectives To compare pulmonary gas exchange during early recovery following general anaesthesia in horses ventilated with FLEX compared with conventional intermittent positive pressure ...

Predictive capability of End Tidal carbon dioxide and its correlation with arterial carbon dioxide in mechanically ventilated children

Journal of Pediatric Critical Care, 2018
Back ground:End-tidal carbon dioxide (ETCO2) is a surrogate, non-invasive measurement of arterial carbon dioxide (PaCO2); however, its clinical applicability in the intensive care unit setting remains unclear in pediatric population.

Agreement between invasive and oscillometric blood pressure measurements during controlled haemorrhage in anaesthetised horses

Equine Veterinary Journal, EarlyView.
Abstract Background Defining the reliability of oscillometry (NIBP) for measuring mean arterial pressure (MAP) during normotension and hypovolaemic hypotension could help with cardiovascular monitoring and management in horses anaesthetised in dorsal recumbency.

Self‐powered H2O2 production using a Zn–air electrochemical cell employing a polymer blend membrane

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hydrogen peroxide (H2O2) is a strong oxidant and a carbon‐free fuel which is synthesized by the costly anthraquinone method, prompting research into highly efficient electrocatalytic processes. RESULTS This study introduces a self‐sustaining Zn–air electrochemical cell with a carbon black cathode and an efficient polymer‐blend ion ...

FFP2 induced breathing resistance does not affect metabolism and well-being during brisk walking and stair climbing - a randomized controlled trial

Journal of Occupational Medicine and Toxicology
Objectives N95 or Type II filtering face pieces (FFP2) are often worn during work hours or on public transportation to prevent airborne infection. The aim of this randomized controlled crossover study is to assess the impact of FFP2 induced breathing ...

Model-based prospective end-tidal gas targeting (MPET) in one subject.

, 2013
The x-axis is labelled in minutes. Note stable end-tidal oxygen tensions during manipulation of end-tidal carbon dioxide and vice versa. For each sequence the breath-by-breath end-tidal carbon dioxide tensions are shown as the solid red dots on the top ...

Contribution of ultrafine particles to alkalinity in a limestone‐treated waterbody

Limnology and Oceanography: Methods, EarlyView.
Abstract While it is well recognized that suspended particles can bias titration‐based total alkalinity (TA), whether addition of minerals for alkalinity enhancement introduces systematic TA artifacts remains poorly quantified. To address this gap, we quantified the contribution of ultrafine particles (< 0.2 μm) to TA titration introduced by limestone (

Metabolic effects of carbon dioxide insufflation during laparoscopic surgery: Changes in pH, arterial partial pressure of carbon dioxide (PaCO2) and end tidal carbon dioxide (EtCO2).

, 2013
Purpose: The purpose of this study was to assess the effects of low tidal volume ventilation on patients undergoing laparoscopic surgery on partial pressure of carbon dioxide, arterial to end tidal carbon dioxide gradient and acid base excess. Methods:

Continuous Respiratory Oscillometry in Pediatric Laparoscopic Surgery—The COMET Study

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Laparoscopic appendectomy is the accepted surgical approach for appendicitis in centers worldwide. Laparoscopic surgery requires the creation of a pneumoperitoneum to facilitate surgical access. Laparoscopic surgery affects the respiratory mechanics of patients under general anesthesia.

Effects of carbon dioxide insufflation on regional cerebral oxygenation during laparoscopic surgery in children: a prospective study

Revista Brasileira de Anestesiologia, 2016
BACKGROUND AND OBJECTIVES: Laparoscopic surgery has become a popular surgical tool when compared to traditional open surgery. There are limited data on pediatric patients regarding whether pneumoperitoneum affects cerebral oxygenation although end-tidal
