مفهوم ماسک صورت ارگونومیک بزرگسال: چشم اندازهای تاریخی و نظری

The fundamental skill required of the anesthesiologist and rescuer is to treat upper airway obstruction and maintain adequate ventilation. Adult one-hand face mask ventilation is a complex technique, often applied with suboptimal results. The adult face mask in use today was not designed for one-handed ventilation but inherited its features from the 19th century face piece. The airway maneuver used with one-handed ventilation is not standardized. An ergonomic face mask has an asymmetrical dome that accommodates the hand grip required for chin lift and may be better for one-hand ventilation. The historical and theoretical considerations patent to the design and technique of the ergonomic face mask are reviewed.

Airway management is one of the most important skills in anesthesiology and emergency medicine practice. In the hospital and prehospital environment, face mask ventilation is a technique readily available in elective and emergent cases for spontaneous and positive pressure ventilation (PPV). Face mask ventilation is technically demanding and often misused, with suboptimal results [1]. The new ergonomic face mask (ErgoMask, King Systems, Noblesville, IN) is designed according to functional and ergonomic principles. This article reviews the historical and theoretical considerations of the ErgoMask.

The goal of face mask ventilation is to provide effective gas movement through a patent unprotected airway without complications. Several strategies were developed to keep the peak airway pressure low (under 20 cm H2O) to favor lung versus stomach inflation [34] and [35]. As with any PPV technique, face mask ventilation should be defined by both clinical (eg, chest movement, excessive gas leak) and objective (oxygen saturation and exhaled carbon dioxide levels, peak airway pressure, and expiratory tidal volume) endpoints. The ErgoMask ventilation technique may minimize peak airway pressure as the design encourages use of an effective airway maneuver (“chin lift grip” with head extension) with an improved seal (control of the whole mask).
