P20-P29: Respiratory and cardiovascular disorders specific to the perinatal period

P27: Chronic respiratory disease originating in the perinatal period

Chronic respiratory diseases originating in the perinatal period are a group of conditions that affect the respiratory system of infants. These conditions start in the period shortly before, during, or after birth, hence the term "perinatal". They're usually long-term issues, meaning they last for a prolonged period or are recurrent. These diseases can arise due to a number of factors, such as premature birth, inadequate lung development, infections, or a lack of oxygen during birth. Infected infants may exhibit symptoms including trouble breathing, persistent cough, wheezing, and reduced feeding or growth. These conditions can progress at different rates and intensities, depending mostly on the severity of the disease, the health of the infant, and the treatment received. In some cases, these diseases might affect the baby's growth and development, but with the appropriate medical management, most children can lead normal lives.
