Airway Anatomy & Physiology

• Position• Open the airway

– - head tilt chin lift maneuver– - jaw thrust maneuver– oropharyngeal and nasopharyngeal airway– - foreign body airway obstruction

Airway

head tilt-chin lift jaw-thrust

Oropharyngeal Airway

Nasopharyngeal Airway

Indication

Breathing•Assessment• Provide rescue breathing

–mouth-to-mouth-and-nose and mouth-to mouth– - bag mask ventilation– laryngeal mask airway– endotracheal intubation– ventilation through a tracheostomy or stoma
