The following diagram shows the depth of respiration of a 45-year old man who suffered a head injury in an automobile accident. This “Crescendo-Decrescendo” pattern of breathing is called as which of the following?
Ans. C. Cheyne-stokes breathing.
- Cheyne-Stokes breathing is the most common type of periodic breathing.
- The person breathes deeply for a short interval and then breathes slightly or not at all for an additional interval.
- This pattern repeats itself about every minute.
- Apnea is a transient cessation of respiration so it is true that Cheyne-Stokes breathing is associated with periods of apnea.
- Biot breathing refers to sequences of uniformly deep gasps, apnea, and then deep gasps.
- Hyperpnea means increased breathing, usually referring to increased tidal volume with or without increased frequency. Tachypnea means increased frequency of breathing.
