Ask open-ended questions to help elicit a full description of the problem. With a child who’s too young to provide a medical history or describe symptoms, direct your questions to the parent or other accompanying adult. One way to gauge cognitive status is to maintain a steady dialogue during the exam. Gear your respiratory assessment not just to the child’s age and size but also to cognitive and functional status.

A child’s chest has cartilaginous structures that increase lung compliance (and also promote cooperation during auscultation).

Children have thinner chest walls than adults and therefore louder breath sounds.

Infants and children have abnormally large tongues, which can cause airway obstruction.

(See Common respiratory disorders in children in pdf format available by clicking download now.) Because of increased airway resistance and nasal breathing, children are at high risk for airway obstruction, even with minimal amounts of mucus or edema.Infants and children have smaller airways than adults, leading to increased airway resistance, which manifests as a rapid respiratory rate.A child’s diaphragm is flatter than an adult’s.Children breathe mainly through the nose until about age 4 weeks (or in some cases, up to several months).They also experience periodic breathing, marked by episodes of rapid breathing and apnea, which may lead to hypoxia. Preterm infants have weak respiratory muscles.Age and respiratory rate have an inverse relationship: the younger the child, the faster the respiratory rate.The lungs develop completely between ages 5 and 6, and alveolar maturation reaches adult capacity during adolescence. Alveoli keep expanding and replicating until about age 4.Consequently, respiratory decompensation occurs more rapidly in children and recovery takes longer. At birth, the respiratory system isn’t fully developed.Keep in mind these essential facts about a child’s respiratory system: (If you’re a pediatric nurse, think of it as a quick refresher course.)

This article provides a basic review of pediatric respiratory assessment. If you’re alert for subtle or seemingly minor details, you can help your patient avoid the lasting effects of hypoxia, or-worst case scenario-loss of life. To help ensure proper diagnosis, aid early preventive treatment, and promote improved outcomes, you need to be familiar with normal pediatric assessment findings. For instance, did you know that a 1-mm occlusion (as from mucus or edema) in a child’s respiratory tract increases airway resistance 16%, causing immediate respiratory compromise? In children, little things can mean a lot. But when the occasion arises, are you confident of your pediatric knowledge base? If you’re a med-surg nurse, you probably don’t care for pediatric patients often. Author Guidelines and Manuscript Submission.
