IMMEDIATE MANAGEMENT OF THE COMPROMISED AIRWAY
++
Securing the airway and assuring adequate ventilation are the first priorities in the resuscitation of any acutely ill or injured patient.1 Without a patent airway and adequate gas exchange other resuscitative measures will almost universally be futile. Thus, attention to the airway must precede or occur simultaneously with any other type of management. The exception is the initial defibrillation in cardiac arrest due to ventricular fibrillation, if it can be performed immediately. (Figure 10–1.)

First, determine the patient’s level of consciousness and note the presence of respirations and grade respiratory effort. In patients with known or suspected cervical spine (C-spine) injury, all assessments and maneuvers should be undertaken with the C-spine immobilized in a neutral position to prevent cord injury. Consider placing a nasal cannula to facilitate apneic oxygenation (see “High-Flow Oxygen” section) if potential for intubation.

A. Apneic, Unconscious Patients
++
If the C-spine is not injured, place the head in the sniffing position with the chin lift maneuver to open the airway (Figure 10–2). For patients with potential C-spine injuries, a jaw-thrust maneuver should be used. Clear the airway of obstructions, using a rigid suction catheter to remove any blood, vomitus, or secretions from the oropharynx. Remove any large obstructing foreign bodies from the oropharynx manually or with Magill forceps (see Chapter 9). Do not perform a blind finger sweep of the oropharynx if foreign body suspected.

If the patient remains apneic, assist ventilation using a bag-valve-mask device (eg, Ambu bag) or mouth-to-mouth breathing (see Chapter 9). If adequate personnel and equipment are available, immediately perform endotracheal intubation.

Administer high-flow oxygen. Clear and position the airway as described above. Identify evidence of upper airway ...
