Airway Management: Ventilation Techniques without Intubation and Supraglottic Airways, Study notes of Human Biology

An overview of airway management techniques for ventilation without intubation, including head tilt/chin lift, jaw thrust, sniffing position, ramping, and bag-mask ventilation. It also discusses the use of naso-oropharyngeal airways and supraglottic airways, such as the Laryngeal Mask Airway (LMA) and King Airway. references to studies that support these techniques.

A patent airway – first step to oxygenation

  • Align axes and open pharynx
  • Head tilt/chin lift

A patent airway – first step to oxygenation

  • Align axes and open pharynx
  • Head tilt/chin lift
  • Jaw thrust
  • Sniffing position
  • Ramping – increases FRC

Ramping

Ramping increases FRC

Increasing FiO

  • Increase alveolar PO
  • Apneic oxygenation

Increasing FiO

  • Increase alveolar PO
  • Apneic oxygenation
  • High-flow nasal cannula

Bag – facemask ventilation

  • C-grip lifts jaw and achieves seal
  • 2-handed approach improves seal
  • Beard, obesity, thick neck, lack of teeth predict difficult BMV

Naso-/oropharyngeal airways

  • Lift tongue, improve access to hypopharynx
  • Can easily obstruct (NPA)
  • Correct size is important

Naso-/oropharyngeal airways

  • Lift tongue, improve access to hypopharynx
  • Can easily obstruct (NPA)
  • Correct size is important
  • Correct insertion is important

Supraglottic airways

  • Require open glottis
  • Many allow fiberoptic intubation through device
  • Laryngeal mask airway (LMA) and variation vs pharyngeal tube (e.g. King airway)

Supraglottic airways - LMA
