Insights

Infants with pulmonary insufficiency may experience growth failure due to high energy expenditure. The doubly labeled water technique confirms increased energy needs in infants with chronic lung disease and other critical conditions.

Area of Science:

  • Pediatric Medicine
  • Neonatology
  • Physiology

Background:

  • Growth failure in infants is often linked to high energy expenditure.
  • Indirect calorimetry has provided inconsistent results for assessing infant energy expenditure.
  • Newer techniques are needed to accurately measure energy expenditure in infants.

Purpose of the Study:

  • To evaluate the utility of the doubly labeled water technique in assessing energy expenditure in infants.
  • To investigate the relationship between pulmonary insufficiency and energy expenditure in infants.

Main Methods:

  • Utilized the doubly labeled water technique to measure energy expenditure.
  • Compared energy expenditure in infants with various clinical conditions, including pulmonary insufficiency, chronic lung disease, and congenital heart disease.
  • Included extremely low birth weight infants and minimally ill infants.

Main Results:

  • The doubly labeled water technique provided evidence for increased energy expenditure in infants with chronic lung disease and congenital heart disease.
  • Elevated energy expenditure was also observed in minimally ill, extremely low birth weight infants.
  • This technique shows promise for studying energy expenditure in diverse infant populations.

Conclusions:

  • The doubly labeled water technique is a valuable tool for accurately assessing energy expenditure in infants.
  • Increased energy expenditure is a significant factor contributing to growth failure in infants with pulmonary insufficiency and other critical conditions.
  • Further research using this method can elucidate energy metabolism in various pediatric clinical settings.

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
Energy Budgets and Reproductive Strategies00:51

Energy Budgets and Reproductive Strategies

Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...

Pulmonary Ventilation: Inhalation

Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.

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...
Factors Affecting Pulmonary Ventilation01:19

Factors Affecting Pulmonary Ventilation

Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

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...
