Inflation of the Endotracheal Tube Cuff in the Pharynx for Ventilation of Paralyzed Patients with Unanticipated Difficult Airway 

Nasolabial Pinch Airway Seal to Enable Positive-Pressure Ventilation: 40 Years of Expanding Use

“…A solution to this problem was found to be using a laryngoscope to guide the ETT tip to the same immediately supraglottic position that had always been a part of NLPAWS use during nasotracheal intubation. 2 Two advantages of this technique of rescue ventilation compared to similar use of a laryngeal mask airway (LMA) are (1) faster access to an ETT and (2) suitability of almost any ETT size.…”

Optimizing Mask Ventilation: Literature Review and Development of a Conceptual Framework

“…When a laryngeal mask airway is not available or unsuccessful, placing an endotracheal tube in the supraglottic area and then hyperinflating the cuff with 50 -60 mL (the poor man's laryngeal mask airway) has been described as a successful rescue technique. [40][41][42] Infraglottic causes of increased air-flow resistance are less commonly encountered but are important to consider as the management is etiology-specific. Causes include airway secretions or mucous plugs, foreign bodies, excessively applied cricoid pressure, bronchospasm, tracheomalacia, tracheal stenosis, and airway or mediastinal mass.…”
