まとめ
肺機能の成長は,強制生命能力 (FVC) と1秒間の強制排気量 (FEV1) を含め,ピークの高さの速度よりも遅れている. 性別による大きな差異は 青春期前期に肺の成長パターンに現れます
科学分野:
- 小児肺科
- 成長と発展
- バイオメトリクス
背景:
- 周期の肺機能の成長は,身長に照らして十分に理解されていません.
- これらのパターンを理解することは 幼児期における呼吸器の健康状態を 評価するのに不可欠です
研究 の 目的:
- 肺機能のピーク成長速度とピーク高度速度 (APHV) の関係を決定する.
- 青春期前期における肺機能の成長軌跡の 性別特有の違いを特定する.
主な方法:
- 2011年から2018年にかけて毎年,肺機能と身長を測定した2099人の子供 (年齢9〜15歳) を対象とした長期的研究.
- APHVに基づいた四半期分類にSITRモデルを使用した.
- APHVに対する1sにおける強制生命能力 (FVC) と強制排気量 (FEV1) の分析されたピーク成長速度タイミング.
主要な成果:
- FVCとFEV1のピークの成長速度は,APHVの2〜12ヶ月後に発生し,後のAPHVではより大きな遅れを示す傾向がありました.
- 男性はFEV1/FVC比率のU型経路を示し,女性とは異なり,年齢とともに減少して増加した.
- 男性のFVCとFEV1は,身長が150〜160センチを超えると女性より有意に高かった.
結論:
- 周期の肺の成長は,身長に関連してかなりの変動を示します.
- この発達段階では,呼吸道と肺パレンキマの成長パターンは,性別による明確な違いがある.

Signs of Puberty
608
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Lung Capacity
51.4K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Factors Affecting Pulmonary Ventilation
1.6K
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...

Physical Assessment of the Respiratory Tract II: Inspection
406
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.

Changes in the Appendicular Skeleton with Age
2.2K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
