Basic Life Support Flashcards
Signs of Upper Airway Obstruction - Snoring & Gurgling
- Snoring: Caused by the soft tissues of the mouth and pharynx. Often
it accompanies the reduced muscle tone of a lowered level of consciousness. - Rattling or gurgling: the sound of fluids in the
upper airway
Signs of Upper Airway Obstruction - Stridor, drooling, hoarseness
Stridor: a harsh, ‘crowing’ noise, which is heard best in inspiration. Suggests obstruction at the level of the
larynx and upper trachea. General illness and temperature usually indicate an infection causing swelling. Obstruction by a foreign body is the other main cause.
- Drooling: the inability to swallow saliva. It suggests blockage at the back of the throat.
- Hoarseness: gross voice change. This suggests obstruction at the level of the larynx.
What to do in cases of suspected supraglottic swelling
In cases of suspected supraglottic swelling,
examination or instrumentation of the throat should not be carried out for fear of causing complete obstruction.
What are the very late signs of airway obstruction?
Cyanosis and reduced haemoglobin saturation readings on a pulse oximeter (SpO2).
What should you assess before any airway intervention
Assess the need for cervical spine protection.
Airway Assessment - Responsiveness
Check for responsiveness
Is the patient alert and responsive to questions?
A verbal reply confirms that there is:
* a maintained and protected airway
* temporarily adequate breathing and circulation
* cerebral functioning
What is the benefit of responsiveness in airway assessment?
If responsive, then the patient will usually be able to elaborate on the cause of the sudden deterioration
that has brought him or her to an ED
What does failure to respond indicate - on airway assessment?
Indicates a significantly lowered
level of consciousness and therefore an airway that may be obstructed and is definitely at risk. There may be a need for airway-opening manoeuvres and action
to protect the airway.
