equipment to remove secretions from mouth and throat, chin lift-jaw thrust maneuver, oral/nasal
airway, bag-valve mask device and mouth-to-mask ventilation device.
What are the main indications for endotracheal intubation? - ANSTo address insufficient
respiratory effort, inadequate airway potency, to protect the airway, or improve oxygenation.
Examples: apnea or hypoventilation, burns, inhalational injury, acute airway obstruction,
expanding neck hematoma, hemodynamic instability, loss of protective reflexes, severe head
