ABCDE Approach Flashcards
(74 cards)
How can the ‘airway’ be assessed?
Get patient to confirm their name & DOB - a normal response confirms a patent airway (move on to B)
What is the most common cause of an airway obstruction in adults?
A reduced conscious level - tongue, soft palate & epiglottis can occlude the upper airway.
If the patient is not verbally responsive, how can you assess the airway?
- Look for chest movements - ensure your head is on the horizontal plane of chest
- Listen for breath sounds
- Feel for air movement on your cheek
- Check for foreign bodies or secretions
What signs may indicate a patient has an obstructed airway?
- Not able to talk in full sentences
- Visibly SOB
- Use of accessory muscles
- Cyanosis
- Angioedema (tongue/lip swelling)
What should you feel for when assessing the airway?
Tracheal position
What would angioedema indicate?
Anaphylaxis
What would a ‘gurgling’ sound indicate?
secretions
What would ‘snoring’ sounds indicate?
soft palate or tongue partially obstructing pharynx
what would a stridor indicate?
foreign body
How would a fully obstructed airway sound?
Silent
What manoeuvres can be done if the patient is unconscious with an obstructed airway?
- Head tilt chin lift
- Jaw thrust
When would the jaw thrust be used over the head tilt chin lift?
If suspected C-spine injury
What airway adjuncts can be used in unconscious patients with an obstructed airway?
- Oropharyngeal
- Nasopharyngeal
Which airway adjunct would be preferred in a patient who was not deeply unconscious?
Nasopharyngeal (better tolerated)
Which airway adjunct would be preferred in a patient who had a suspected base of skull fracture?
Oropharyngeal
How can the correct size of oropharyngeal adjunct be measured?
Measure from angle of mouth to edge of mandible
If patient not breathing/hypoxic, ventilate using bag and mask (2 person technique). What rate should you squeeze the bag at?
10-12 per minute
What is paradoxical breathing a sign of?
Sign of respiratory distress that occurs with increasing partial airway obstruction.
Describe paradoxical breathing
- Chest contracts during inspiration and expands during exhalation (opposite of normal)
- Vertical rib cage movement
- The abdomen moves outwards as the diaphragm moves downwards, but the negative pressure generated against the obstructed airway draws the chest inwards
- Abdominal hollowing, no distension
Define ventilation
The amount of air the reaches the alveoli
Define perfusion
The amount of blood that reaches the alveoli
Define a V/Q mismatch
Mismatch between alveolar ventilation and alveolar blood flow
What PaO2 defines respiratory failure?
PaO2 < 8 kPa
What response should always be done in any patient presenting SOB?
Sit patient up
Give 15L oxygen on a non-rebreathe mask
