RRAPID: A Flashcards
Airway recognition
Look - for chest movements, use of accessory muscles
Listen - Abnormal sounds?
Feel - airflow on inspiration + expiration
Airway management
Management:
Call for help
O2 15L via non-rebreathe mask
Head tilt chin lift
Remove foreign bodies/ suction secretions
Airway adjuncts
Ventilate using bag + mask if patient not breathing
How to assess hypotensive pt?
Assess:
HR - is HR causing the hypotension (arrhythmia)
Volume status
Cardiac performance - MI? myocarditis?
Systemic vascular resistance - sepsis, anaphylaxis?
Causes of airway obstruction
Reduced consciousness
Foreign bodies
Secretions
Swelling (infection, anaphylaxis)
Clinical presentation + causes of airway obstruction
Snoring - pharynx is partially obstructed by soft palate/ tongue
Choking
Gurgling noises - due to secretions
Stridor - harsh high pitched noise on inspiration due to turbulent flow
Silent if its complete
See-saw movement of abdo + chest due to inspiratory effort against closed airway
What is paradoxical breathing?
See saw movement of abdo and chest
Abdomen moves out as diaphragm moves down but negative pressure generated against the obstructed airways draws chest inwards
Describe an oropharyngeal airway - when is it used, what sizes and how to measure size, when to use with caution?
Guedel airway
Used for unconscious patients to overcome soft palate obstruction by preventing backward displacement of tongue
Available in sizes 2-4
Measure size from vertical distance from patients incisors + angle of jaw
Caution in pts that are only lightly unconscious
Describe how a nasapharyngeal airway is inserted + what it looks like?
Made from soft plastic, bevelled at one end + flanged at other
Inserted through nose, perpendicular to hard palate with twisting action until tip lies in posterior pharynx
When is a nasapharyngeal airway useful + when is it contraindicated?
Better tolerated for more conscious patients
High incidence of bleeding so only use when oro airway is not tolerated
Useful in patients whose mouth can’t be opened (ie in seizures)
Contraindicated in pts with skull base fractures
What is a laryngeal mark airway?
Wide bore tube with elliptical inflated cuff which forms a seal around laryngeal opening
Only used for deeply unconscious/ anaesthetised pts
How to use a bag + mask to ventilate?
Self inflating AMBU bag connected to mask
Squeeze bag at rate of 10-12 per minute
When is a definitive airway indicated?
GCS <8 or rapidly falling LOC
Causes of airway obstruction
CNS depression Foreign body Trauma Blocked tracheostomy Swelling (infection/ oedema) Laryngospasm, bronchospasm
How does airway obstruction kill?
Cerebral oedema Pulmonary oedema Exhaustion Hypoxic brain injury Secondary apnoeas
