Emergency Medical Technician (EMT) Intermediate Practice Exam

Cheyne-Stokes respirations are characterized by:

1. Rapid breathing with no pauses

2. Tachypnea and bradypnea with alternating apneic periods

3. Consistent breathing rate

4. Sudden cessation of breathing followed by gasping

The correct answer is: Tachypnea and bradypnea with alternating apneic periods

Cheyne-Stokes respirations are characterized by a specific pattern of breathing that includes alternating periods of tachypnea (rapid breathing) and bradypnea (slow breathing), along with intervals of apnea (the absence of breathing). This cycle typically consists of a gradual increase in the rate and depth of breathing, followed by a decrease, leading to a complete cessation of breath before the cycle repeats. This pattern is commonly associated with conditions such as heart failure, head injuries, and other neurological conditions. The nature of Cheyne-Stokes respirations reflects critical changes in brain function, particularly in areas responsible for the control of respiration. Understanding this breathing pattern is crucial for EMTs, as it can guide the assessment and management of patients experiencing altered levels of consciousness or severe underlying medical conditions. Recognizing the alternating nature of this pattern is key for appropriate patient evaluation and intervention.
