Basic air way management Flashcards
What are the four causes of airway obstruction?
Tongue, edema(swelling), fluid, foreign bodies
Name two ways to open up airway in an unconscious patient:
Head-tilt chin-lift and the jaw-thrust maneuver (cervical spin injury)
How do you artificially ventilate a patient with a stoma?
Clear mucus plug or secretions from the stoma. Leave head and neck in neutral position. Use a pediatric bag-valve-mask and establish a seal around the stoma. Ventilate at the appropriate rate for the age of the patient.
The main advantage of using an NPA over an OPA is that?
It is less likely to be rejected if the patient has a gag reflex.
What is the general sequence of evaluation a conscious vs unconscious patient?
Conscious patients are evaluated with the traditional ABC: airway first, then breathing, and circulation last. Unconscious patients are evaluated with CAB order: circulation, airway, then breathing.
What are the three rules of suctioning?
- Wear PPE, 2. Suction no longer than 10-15 seconds, 3. Suction on the way out.
One-rescuer BVM finger positioning?
E-C clamp
What can happen if you hyperventilate a patient?
Increased negative pressure in the thorax leading to decreased blood flow to the heart.
Jaw-thrust-maneuver is used when?
You suspect trauma
What are three contraindications of using a Combitube?
Intact gag reflex, less than 16-years-old, caustic substance ingestion.
How to measure an NPA?
Measure from tip of nose to earlobe
An SpO2 of less then ____ indicates hypoxia
94%
How do you measure an OPA?
Measure from the corner of the mouth to the earlobe
When inserting an OPA and the patient vomits, what do you do?
Remove the adjunct and suction as needed.
Severe allergic reaction; airway swelling and dilation of blood vessels (within 30 mins of exposure). Treatment is epinephrine, antihistamines, oxygen.
Anaphylaxis
