Protocol - Respiratory Rate - Infant
For infants (up to 3 years of age), a study staff member listens to breath sounds via a stethoscope lightly placed on the infant’s chest for 60 seconds to count the number of complete respiratory cycles (one inspiration and one expiration). Note that because respiratory rate in infants is significantly different when awake versus when asleep, studies should be consistent in measuring this variable.
Alternatively, observe the rise and fall of the chest for a complete inspiration and expiration and count for a full 60 seconds.
1) Infants (up to 3 years) should be calm, either awake (including quietly seated or quietly playing) or asleep (sleep not associated with any spontaneous movement, including no eye movements or vocalizations). Infants: count breath sounds in a complete respiratory cycle for 60 seconds with a stethoscope gently placed on infant’s chest.
Alternatively, with fingers near the radial artery, observe respirations. Observe the rise and fall of the chest. After a complete cycle of inspiration and expiration, count for a full 60 seconds.

Process and Review
The Expert Review Panel #6 (ERP 6) reviewed the measures in the Respiratory domain.
Guidance from ERP 6 includes:
• Replaced protocol
• New Data Dictionary

Respiratory rate is the number of breaths an individual takes within a specific amount of time (frequently given in breaths per minute).
Respiratory rate is a low-burden, quantitative variable that can be used to distinguish individuals with and without various forms of lung disease.
