Recognizing Respiratory Emergencies Flashcards

A 4-year-old child is brought to the clinic with a 'barking' cough, hoarseness, and inspiratory stridor. The child is alert, has no cyanosis, and mild intercostal retractions are visible. Based on the PEARS assessment, which type of respiratory emergency is most likely?

Answer: Upper airway obstruction

The classic presentation of a 'barking' cough, hoarseness, and inspiratory stridor points towards an issue in the upper airway. [18, 20] Croup is a common cause of these symptoms in young children and is a form of upper airway obstruction. [7, 18, 20] Lower airway obstruction typically presents with wheezing on expiration, lung tissue disease with crackles, and disordered control of breathing with an irregular respiratory pattern. [1, 7]

Which of the following clinical signs is most indicative of a pediatric patient transitioning from respiratory distress to respiratory failure?

Answer: A significant decrease in respiratory rate and effort

While tachycardia, nasal flaring, anxiety, retractions, and audible breath sounds are signs of respiratory distress, a significant decrease in respiratory rate and effort (bradypnea or inadequate breathing) is an ominous sign. [5, 8] It indicates the child is tiring and can no longer compensate, which is a hallmark of respiratory failure. [5, 8]

You are assessing an 18-month-old who is lethargic with a rapid, shallow respiratory rate, grunting, and crackles heard on auscultation. These findings are most consistent with which category of respiratory problem?

Answer: Lung tissue disease

Grunting and crackles are characteristic signs of problems within the lung tissue itself, such as pneumonia or pulmonary edema. [1, 7] Grunting is an effort to keep alveoli open. [8] Upper airway obstruction presents with stridor, lower airway with wheezing, and disordered control of breathing involves an abnormal breathing pattern. [1, 7]

A 6-year-old presents with sudden onset of respiratory distress while playing. The child is unable to speak, has a weak, ineffective cough, and you hear high-pitched inspiratory stridor. What is the most important initial step?

Answer: Assess for severe airway obstruction and be prepared to provide relief maneuvers

The sudden onset, inability to speak, and weak cough are signs of a severe (or complete) foreign body airway obstruction. The immediate priority is to recognize this and be prepared to deliver age-appropriate relief maneuvers (like abdominal thrusts for a child over 1 year). Encouraging coughing is appropriate for a mild obstruction, but not a severe one.

Which of the following is a key differentiator between respiratory distress and respiratory failure in a pediatric patient?

Answer: The patient's level of consciousness

In respiratory distress, the child is compensating and is typically anxious but alert. [5] As the condition progresses to respiratory failure, inadequate oxygenation and ventilation affect brain function, leading to a decreased level of consciousness, such as lethargy, drowsiness, or unresponsiveness. [3, 5] While heart rate changes and signs of increased work of breathing (nasal flaring) are present in both, the change in mental status is a critical sign of failure. [5]

A 2-year-old with a known neuromuscular disease is brought in with an irregular, shallow breathing pattern and periods of apnea. This presentation is most characteristic of which type of respiratory emergency?

Answer: Disordered control of breathing

Disordered control of breathing is characterized by an abnormal breathing pattern, such as irregular rate, shallow breathing, or apnea. [7] This is often caused by a problem in the central nervous system or with the nerves and muscles that control breathing, such as in neuromuscular diseases. [7, 19]
