Infants have increased respiratory rates compared to adults because their lungs are smaller and less efficient at exchanging oxygen, requiring more frequent breaths to meet their metabolic needs. Additionally, infants have underdeveloped respiratory control centers in the brain, leading to a faster respiratory rate to maintain proper oxygen levels.

Does increase in tidal volume changes will accompany the loss of elasticity of the lungs associated with aging?
Yes, as elasticity decreases with age, the lungs may require an increase in tidal volume to maintain adequate gas exchange. This compensation helps overcome the decreased ability of the lungs to expand and contract efficiently. However, this increased tidal volume may lead to increased respiratory effort and potential respiratory muscle fatigue.
Why has life expectancy increased in the U.S. since 1900?
Life expectancy in the U.S. has increased since 1900 due to advancements in medical technology, improved public health measures, better sanitation, access to clean water, and increased awareness of healthy lifestyle choices. These factors have collectively led to a decrease in infant mortality rates and a decline in deaths from infectious diseases.
Did birth rate in 1920s decrease or increase?
In the 1920s, birth rates generally decreased in industrialized nations due to factors such as economic instability, changing social norms, and increased access to contraception.
What are the factors that contribute to global aging?
Factors that contribute to global aging include declining fertility rates, increased life expectancy, and advancements in healthcare leading to lower mortality rates. Additionally, industrialization and urbanization have also played a role as people are choosing to have fewer children and focus on their careers.
Average population age in France?
The average population age in France is around 42 years old. This is due to factors such as lower birth rates and increased life expectancy contributing to an aging population.
Which of the following signs of respiratory distress is typically unique to infants and children?
The signs of respiratory distress in infants and children are grunting, increased rate of breathing, chest retraction and difficulty in feeding.
Which of these is not an effect of a stimulant use hallucinations increased heart and respiratory rates anxiety reduction or agitation?
Anxiety response
What causes respiratory rates to go up?
Aerobic exercise causes respiratory rates to go up.
Is the respiratory rate lowest in newborn infants?
No, it's highest.
Why are apical pulse usually taken on infants and children?
because infants have higher average pulse rates.
Where are the respiratory centers housed which control involuntary breathing rates?
The respiratory centers which control involuntary breathing rates are in the medulla and pons.
What is considered an infants respiratory rate is 45 beats per minute?
irregular
Respiratory problems in premature infants may be the result of their inability to produce enough?
surfactant
What activities place an extra demand on your cardiovascular and respiratory systems?
Activities such as running, cycling, swimming, and high-intensity interval training place an extra demand on your cardiovascular and respiratory systems. These activities require increased oxygen delivery to working muscles, leading to higher heart rates and breathing rates to meet the increased demand for energy.
What is the term for tachypnea?
Increased respiratory rate.
What is respiratory distress syndrome in premature infants?
Respiratory distress syndrome (RDS) in premature infants is a condition where the infant's lungs are not fully developed, leading to difficulty in breathing. It is caused by insufficient production of a substance called surfactant, which helps the lungs stay open. Treatment often involves providing the infant with respiratory support and surfactant replacement therapy.
What is normal respiratory rates?
12 to 15 per minute.
