Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.8K
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...

The Bronchial Tree01:23

The Bronchial Tree

3.5K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Acute Pharyngitis

1.5K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Chronic Pharyngitis01:23

Chronic Pharyngitis

4.6K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Common Respiratory Disorders01:31

Common Respiratory Disorders

878
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

科学领域:

  • 儿童医学
  • 传染性疾病
  • 呼吸系统医学

背景情况:

  • 在高收入国家, 病毒性支气管炎是婴儿入院的主要原因.
  • 呼吸道同胞病毒是主要病原体,占病例的60- 80%.
  • 诊断通常是临床的,因此无需进行病毒检测.

研究的目的:

  • 审查目前基于证据的病毒性支气管炎治疗建议.
  • 评估各种干预措施的有效性和适当使用.
  • 解决无效干预护理的持续挑战.

主要方法:

  • 审查高质量的证据和系统审查.
  • 对临床实践指南的分析.
  • 对葡萄糖皮质激素,支气管扩展剂,高血压盐水和高流量治疗等特定干预措施的数据的评估.

主要成果:

  • 管理人员应专注于支持性护理:补水和补氧.
  • 葡萄糖皮质剂和支气管扩展剂没有证明有益处.
  • 高血压盐水需要进一步的证据;高流量治疗仅限于救助缺氧婴儿,并且不会降低ICU入院或输管率.

结论:

  • 证据强烈支持病毒性支气管炎的仅支持性护理方法.
  • 尽管有指导方针,但干预疗法仍被广泛使用,这给实施带来了重大挑战.
  • 专注于消除无效治疗对于最佳患者护理至关重要.
