Airway &
Ventilatory Management
Learning Objectives
 Identify the clinical settings in which airway
compromise is likely to occur
 Recognize the signs and symptoms of acute
airway obstruction.
 Describe the techniques to establish and
maintain a patent airway and confirm the
adequacy of ventilation and oxygenation,
including pulse oximetry monitoring (and CO2
colorimetric monitoring)
 Define “definitive airway” and outline the
steps needed to maintain oxygenation
before, during, and after establishing a
definitive airway.
Airway Problems are a common
cause of Preventable Deaths
 Failure to recognize airway need
 Technical difficulties
 Inability to establish airway
 Failure to correct an incorrectly placed airway
 Dislodgement of a correctly placed airway
 Delay in establishing adequate
ventilation
 Aspiration of Gastric Contents
Clinical Scenarios increasing risk
 Head Injury (decreased
consciousness)
 Facial Fractures
 Direct Airway Injury
 Hoarseness, s/c
emphysema & palpable #
 Thoracic Injury
Objective Signs of Airway Obstruction
 Look if agitated / obtunded
Agitation  hypoxia,
Obtunded  Hypercarbia
Using accessory muscles?
 Listen for abnormal sounds
Noisy breathing is obstructed breathing
 Feel the trachea
Problem recognition
 Assuring an adequate airway is only the
first step
 The patient need to be ventilating
adequately
 Ventilatory compromise
 Airway obstruction
 Altered ventilatory mechanics
 CNS depression
Is my patient breathing enough ?
Objective Signs of Inadequate Ventilation
 Look for chest wall
movement
 Listen for movement of
air in both lungs
Tachypnea may mean
air hunger
 Use a pulse oximeter
 Oxygen saturation
 Peripheral perfusion
Management
 A rigid suction device is essential, all
trauma victims need supplemental O2
 Airway maintenance
 Chin lift
 Jaw thrust
 Oropharyngeal airway
 Nasopharyngeal airway
Position for unconscious
patient
A definitive airway requires a
tube present in trachea with
cuff inflated, connected to
some form of oxygen enriched
assisted ventilation and
secured in place with tape
When do we need a definitive
airway?
 Need for airway protection
 Unconscious
 Severe maxillofacial trauma
 Risk of aspiration (bleeding, vomiting)
 Risk of obstruction (neck hematoma,
laryngeal & tracheal injury, stridor)
When do we need a definitive
airway?
 Need for ventilation
 Apnea
 Neuromuscular paralysis
 Unconscious
 Inadequate effort
 Tachypnea, cyanosis
 Hypoxia
 Hypercarbia
 Severe head injury (for hyperventilation)
Definitive Airway –
Endotracheal intubation
In line cervical stabilization
Cricoid pressure to prevent aspiration
Facio-maxillary trauma
Mid Face # causing airway compromise
Definitive Airway  Surgical
Cricothryroidotomy
Cricothyroidotomy
Site & Incision
Tube insertion
Tracheostomy for facio-maxillary tauma
Head & Neck Burns
Premptive tracheostomy
Oxygenation
 A measured saturation of 95 % or
greater by pulse oximetry is a strong
corroborative evidence of adequate
peripheral arterial oxygenation
 Pitfalls
 Profound anemia
 hypothermia
Ventilation
 Bag valve – mask
technique
 Ventilators
 Beware of problems
of positive pressure
ventilation like
conversion of simple
to tension
pneumothorax, or
creation of
pneumothorax
Barotrauma from ventilator
Pitfalls
 Inability to intubate
 Inability to provide surgical airway
 Trauma patient may vomit & aspirate (suction
available)
 Gastric distension from ventilation with mask
 aspiration & hypotension from IVC
pressure
 Equipment may fail (laryngoscope bulb,
batteries, cuff rupture, oximeter probe)
?
Summary
 Actual or impending airway obstruction
should be suspected in all injured patients.
 With all airway maneuvers, the cervical
spine must be protected by in-line
immobilization.
 Clinical signs suggesting airway
compromise should be managed by
securing a patent airway and providing
adequate oxygen-enriched ventilation.
 A definitive airway should be inserted if there
is any doubt on the part of the doctor as to
the patient’s airway.
Summary - 2
 A definitive airway should be placed early after
the patient has been ventilated with oxygen-
enriched air, and prolonged periods of apnea
must be avoided.
 Airway management requires assessment and
reassessment of airway patency, tube
position, and ventilatory effectiveness.
 The selection of orotracheal or nasotracheal
routes for intubation is based on experience
and skill level of the doctor.
 Surgical airway is indicated whenever an
airway is needed and intubation is
unsuccessful.
