Insights

Forced oscillation technique is feasible for assessing lung function in preschool children with neonatal chronic lung disease (nCLD). Children with nCLD showed worse lung function, reflecting neonatal disease severity.

Area of Science:

  • Pediatric Pulmonology
  • Neonatal Medicine
  • Respiratory Physiology

Background:

  • Neonatal chronic lung disease (nCLD) can cause respiratory dysfunction in young children.
  • Assessing lung function in children too young for spirometry is challenging.
  • Forced oscillation technique (FOT) offers a potential non-invasive method.

Purpose of the Study:

  • To evaluate the feasibility of FOT in preschool children with nCLD.
  • To investigate the relationship between neonatal factors and lung function in these children.
  • To characterize respiratory dysfunction in nCLD patients using FOT.

Main Methods:

  • Respiratory function tests using FOT were performed on 64 children (3.2-6.6 years) with nCLD.
  • Respiratory resistance and reactance were measured at 6, 8, and 10 Hz and expressed as z-scores.
  • Feasibility, within-test variation, and between-test repeatability were assessed.

Main Results:

  • Technically satisfactory FOT data were obtained from 77% of the children.
  • Children with nCLD exhibited significantly abnormal respiratory resistance and reactance (z-scores differed from zero).
  • Abnormalities correlated with the need for hospital oxygen administration during the neonatal period.

Conclusions:

  • FOT is a feasible technique for assessing preschool children with nCLD in a clinical setting.
  • Children with nCLD demonstrate impaired lung function compared to healthy peers.
  • FOT results appear to reflect the severity of neonatal lung disease.

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Assessment of Respiration01:23

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
