Basic Airway Manoeuvres, Adjuncts & Bag-Valve-Mask

Also known as Basic airway skills · Bag-valve-mask · BVM · Guedel airway · Oropharyngeal airway · Nasopharyngeal airway · Jaw thrust · Head tilt chin lift · EC clamp · Apnoeic oxygenation

The 'A' of ABCDE. Basic airway skills are the non-invasive manoeuvres and adjuncts that establish and maintain a patent airway and oxygenate the patient before a definitive airway. Jaw thrust and head-tilt/chin-lift relieve obstruction by the tongue; the oropharyngeal (Guedel) and nasopharyngeal airways stent the pharynx; and the bag-valve-mask with a two-handed C-E grip, reservoir and PEEP valve ventilates the unprotected airway. Most 'can't intubate' situations are rescued by excellent basic airway skills and bag-valve-mask ventilation. Apnoeic oxygenation (THRIVE) extends safe apnoea time.

The one-line answer

Basic airway skills are the "A" of ABCDE — and the skill that rescues the patient when intubation fails. In the unconscious patient the tongue is the commonest obstruction; open the airway with a jaw thrust (cervical-spine safe) or head-tilt/chin-lift, hold it open with a sized oropharyngeal or nasopharyngeal airway, and oxygenate with a two-handed C-E bag-valve-mask on 15 L/min with a reservoir and a PEEP valve. Most airway deaths are hypoxia from poor basic skills, not a failed tube — NAP4 made that the recurring lesson.[1][2][3]

Meet the patient

A 75-year-old man on the ward, an hour after intramuscular morphine for a fractured neck of femur, has stopped responding. His chest still see-saws, but the sonorous snoring has just gone silent. The saturation is 84 percent and falling. The airway has closed — and the silence, not the snoring, is the emergency.[1][2]

The two questions that decide the next sixty seconds are the two that decide every obstructed airway: is it open? and can I oxygenate through it? Hold those two questions and every manoeuvre below slots into place.[1]
