ABCDE Approach Flashcards
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
What 2 observations should always be done during ‘breathing’?
- O2 saturations (put on probe)
- Respiratory rate
What observation should be done during ‘breathing’ if concerned about an asthma attack?
Peak flow (PEFR)
What response should be taken if the SpO2 is low?
15L oxygen via a non-rebreathe mask
Describe some potential steps for the ‘look’, ‘listen’ and ‘feel’ aspect of ‘breathing’
Look:
- Symmetrical chest expansion & depth
- Breathing effort
Listen:
- Auscultation of lung lobes
Feel:
- Percussion
- Chest expansion
What condition would reduced breath sounds with coarse crepitations and bronchial breathing over a certain area indicate?
Pneumonia
