“…In this study a controlled environment was used during induction of anaesthesia [11,12]. When compared to facemask ventilation using a standard Esmarch manoeuvre, a nasopharyngeal, or an oropharyngeal airway, the Jaw-Thrust-Device was more effective in reducing airway resistance and thus increasing expiratory tidal volumes during pressure-controlled facemask ventilation.…”

SummaryDespite being a standard procedure during induction of anaesthesia, facemask ventilation can be a major challenge especially for inexperienced anaesthetists. We manufactured a Jaw-Thrust-Device designed to keep the patient's jaws in an optimised position, and thus to maintain the airway in a permanently patent state. Using a cross over design, we compared the influence of using the Esmarch manoeuvre (bimanual jaw-thrust), a nasopharyngeal airway, an oropharyngeal airway, or the Jaw-Thrust-Device on airway physiology in 50 healthy adults with body mass index < 35 kg.m )2 , undergoing standard facemask ventilation for routine induction of anaesthesia.The main study endpoints were expiratory tidal volumes, airway resistances, and gas flow rates. The Jaw-Thrust-Device was more effective in increasing expiratory tidal volumes and peak inspiratory flow than a standard Esmarch manoeuvre, and was more effective than both nasopharyngeal and oropharyngeal airways in decreasing airway resistance.

“…Ventilator settings for reoxygenation are shown in Figure 4. Two studies have compared handheld ventilators to BVMs for non-intubated ventilations; these studies have shown the handheld ventilator to be safe and that it may be associated with fewer complications (25,26). The improved valve structure and more precise settings of a standard rather than handheld ventilator make it even more desirable.…”

“…1). Of these, six were manikinbased studies and three were clinical trials [15][16][17][18][19][20][21][22][23]. The ventilatory variables that were recorded in bench studies were tidal volume (V T ), ventilation rate (V R ), peak airway pressure (P peak ), peak inspiratory flow (PF), minute volume (V m ), gastric inflation volume (V gastric ), inspiratory time fraction (T i /T tot ), inspiratory time (I time) and inspiratory/expiratory ratio (I/E).…”

Performance of manual ventilation: how to define its efficiency in bench studies? A review of the literature

et al. 2015

Bench studies have become the preferred way to evaluate the performance of airway equipment, since clinical trials are not specifically required before marketing these devices. However, it is difficult to assess the efficiency of ventilation without recording physiological data. This review analyses how efficiency of manual ventilation has been defined in recent studies, and how their results may be affected. We searched electronic databases from 2000 to April 2014. The main inclusion criterion was the analysis of performance of ventilation. Nine relevant articles were selected from 53 eligible publications. Most studies used the same parameters; tidal volume and ventilation rate. However, there were significant differences between the definitions of performance of ventilation, both in terms of criteria of judgement and methods of analysis. None of these approaches is able to provide a clear understanding of variability of ventilation during a given period. A new definition may increase the relevance of bench studies to clinical medicine, by more appropriately assessing the performance of ventilation.
