The first-line treatment for anaphylaxis
What is Epinephrine 1:1,000
the most common cause of allergic reactions in the United States
What is pollen?
the structure that prevents food and liquids from entering the trachea during swallowing
What is the epiglottis
part of the lower airway is responsible for gas exchange
What is alveoli?
OPA
what is an oropharyngeal airway?
How soon after exposure to an allergen can anaphylaxis symptoms appear?
Within minutes
the substance released by the immune system during an allergic reaction that causes inflammation and swelling
what is histamine?
the primary cause of upper airway obstruction in an unconscious patient
what is the tongue falling back and blocking the airway?
the term for the narrowing of the lower airways, leading to wheezing and difficulty breathing
What is bronchoconstriction?
the flow rate range of oxygen when using a nasal cannula
1–6 liters per minute
The adult dose of Epinephrine 1:1,000 from a vial
What is 0.5mg?
type of cells in the body are responsible for releasing histamine during an allergic reaction
What are mast cells?
the term for a high-pitched breathing sound often heard in patients with upper airway obstruction
What is stridor?
The sound is often heard on auscultation in a patient with lower airway obstruction due to bronchoconstriction
What is wheezing?
oxygen delivery device is used to provide a high concentration of oxygen to a patient who is breathing but needs more oxygen than a nasal cannula can provide
What is a non-rebreather?
common signs and symptoms of anaphylaxis
What is swelling of the face, lips, tongue, difficulty breathing, and hypotension
over the counter medication commonly used to treat mild allergic reactions like hives and itching

the first step in managing an upper airway obstruction in a responsive, coughing adult patient
what is encouraging them to keep coughing?
the main difference between emphysema and chronic bronchitis, two conditions related to chronic obstructive pulmonary disease (COPD)
Emphysema involves the destruction of alveolar walls, while chronic bronchitis involves inflammation and mucus production in the bronchi
the purpose of a bag-valve-mask (BVM)
To provide positive pressure ventilation to a patient who is not breathing or not breathing adequately
biphasic anaphylaxis
What is a return of anaphylactic symptoms after the initial response to treatment
the most severe allergic reaction that can cause difficulty breathing and shock
What is anaphylaxis?
This condition causes inflammation of the larynx, leading to voice changes and difficulty breathing
What is laryngitis?
the major passages and structures of the lower airway
What is the trachea, lungs, bronchi, bronchioles, and alveoli?
