Insights

Optimizing incubator settings for preterm infants is crucial for growth. Personalized incubator adjustments, guided by calculation programs, can improve nutrition and growth rates in very low birth weight infants.

Area of Science:

  • Neonatology
  • Infant Nutrition
  • Thermoregulation

Background:

  • Achieving intrauterine growth rates in preterm infants is challenging due to unpredictable individual factors.
  • Adequate nutrition is critical for the growth of preterm infants.

Purpose of the Study:

  • To compare estimated heat balance with caloric intake and growth rate in Very Low Birth Weight Infants (VLBWI).
  • To investigate the interrelationship between thermal equilibrium and growth rate in VLBWI.

Main Methods:

  • A calculation program for infant incubators was utilized.
  • A cohort of 32 VLBWI was monitored for 14-28 days.

Main Results:

  • An association between thermal equilibrium and growth rate was identified.
  • Standardized incubator settings did not prevent negative thermal balance or poor growth.

Conclusions:

  • Personalized incubator settings, determined via a calculation program, show potential for enhancing nutrition and growth in preterm infants.
  • Individualized thermal management may improve outcomes for VLBWI.

Temperature and Thermal Equilibrium01:11

Temperature and Thermal Equilibrium

Heat and temperature are essential concepts for everyone every day. The study of heat and temperature is part of an area of physics known as thermodynamics. It is not always easy to distinguish heat and temperature.
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...

Temperature Measurement Sites01:14

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Body Temperature01:07

Body Temperature

Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Trophic Efficiency00:46

Trophic Efficiency

Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Efficiency of The Carnot Cycle01:16

Efficiency of The Carnot Cycle

The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...
