Insights
Bronchopulmonary dysplasia (BPD) involves altered breathing control in preterm infants. This impacts respiratory function during exercise, sleep, hypoxia, and lung disease, requiring further research.
Area of Science:
- Neonatology
- Pediatric Pulmonology
- Respiratory Physiology
Background:
- Bronchopulmonary dysplasia (BPD), a chronic lung disease of prematurity, affects approximately 30% of preterm infants annually.
- BPD is linked to mechanical ventilation and/or high oxygen exposure at birth.
- Altered ventilatory control is a key characteristic of BPD.
Purpose of the Study:
- To describe changes in ventilatory control in patients with BPD.
- To examine ventilatory control under metabolic stressors like exercise, sleep, hypoxia, and lung disease.
- To identify future research directions in BPD and ventilatory control.
Main Methods:
- Focused on human infant, child, and adult studies.
- Analyzed alterations in chemoreceptor function, respiratory muscle function, and suprapontine control.
- Contextualized findings within metabolic stressors challenging O2 supply and CO2 elimination.
Main Results:
- Patients with BPD exhibit altered chemoreceptor and respiratory muscle function.
- Suprapontine control mechanisms are also affected in BPD.
- Ventilatory control dysfunctions are evident under physiological stress.
Conclusions:
- Ventilatory control deficits are a significant aspect of BPD.
- Understanding these deficits under stress is crucial for managing BPD.
- Longitudinal studies with defined cohorts are recommended for future research.
Abstract:
Bronchopulmonary dysplasia (BPD), or chronic lung disease of prematurity, occurs in ~30% of preterm infants (15,000 per year) and is associated with a clinical history of mechanical ventilation and/or high inspired oxygen at birth. Here, we describe changes in ventilatory control that exist in patients with BPD, including alterations in chemoreceptor function, respiratory muscle function, and suprapontine control. Because dysfunction in ventilatory control frequently revealed when O2 supply and CO2 elimination are challenged, we provide this information in the context of four important metabolic stressors: stresses: exercise, sleep, hypoxia, and lung disease, with a primary focus on studies of human infants, children, and adults. As a secondary goal, we also identify three key areas of future research and describe the benefits and challenges of longitudinal human studies using well-defined patient cohorts.

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
