Leak and obstruction with mask ventilation during simulated neonatal resuscitation.
OBJECTIVES To evaluate mask technique during simulated neonatal resuscitation and test the effectiveness of training in optimal mask handling. STUDY DESIGN Seventy participants(consultants, registrars and nurses) from neonatal units were asked to administer positive pressure ventilation at a flow of 8 l/min and a frequency of 40-60/min to a modified leak free, term newborn manikin (lung compl...
متن کاملInfluence of cuff volume on oropharyngeal leak pressure and fibreoptic position with the laryngeal mask airway.
We studied the size 4 laryngeal mask airway (LMA) to test the hypothesis that oropharyngeal leak pressure and fibreoptic position improves with increasing cuff volume. After LMA insertion, 50 anaesthetized adult patients had the cuff inflated in 5-ml increments to 40 ml. Oropharyngeal leak pressure was optimal at 15 ml and decreased at higher volumes. The fibreoptic position was optimal at 0-20...
متن کاملFactors affecting the location and shape of face seal leak sites on half-mask respirators.
While there have been a number of studies on the effect of leak site and shape on the magnitude of measured leakage through respirator face seals, there have been very few studies to identify the location and size of these leaks. In a previous study we used a method of identifying the location and shape of respirator leaks on a half-mask respirator by the deposition of a fluorescent tracer duri...
متن کاملRescue Mask with Prefabricated Leak for Reduction of Accidental Stomach Inflation During Lay Rescuer Ventilation
Objective: To evaluate the efficacy of a simple method to minimize gastric inflation in unprotected airways during resuscitation procedures. Methods: Ventilation of an airway simulator by use of a hose extended mask with leak and without leak and with or without additional oxygen (15 litres per minute). Experimental settings with artificial lung at a compliance = 300ml/ kPa and resistance = 0,5...
متن کاملUn petit cercle, un grand exemple (دایرهای کوچک، سرمشقی بزرگ )
نام هانری کربن با دو دایره گره خورده است: دایرة ارانوس و دایرة تهران؛ دایرههایی که مطابق منظر کربن، میتوان آنها را بهدرستی رمزی و مثالی خواند. این مقاله به دایرة تهران اختصاص دارد، دایرهای تحقیقی که با حضور اندیشمندانی چند، و با محوریت دو شخصیت از شرق و غرب، علامه سید محمد حسین طباطبایی و هانری کربن، شکل میگرفت. برغم همه مشکلات فنی و فیزیکی ارتباط کلامی، این دو مرد، به خوبی با یکدیگر «مقاب...
