Pediatric pulmonologists treat infants, children, and adolescents with common lung disorders, deficiencies in the muscles that support breathing, and problems with the neuronal regulation of relaxation. This combines treatment with more oxygen, in-house mechanical ventilation, genuine ventilation, etc. If you anticipate that your adolescent has breathing problems or lung problems, a paediatric pulmonologist has the knowledge and skills to handle your child. Pediatric pulmonologists diagnose, treat, and supervise children from birth to age 21 who have respiratory and lung conditions.
