概括
大声的半遮蔽语音练习 (SOVTEs) 与对话的声音相比,增加了声音负载. 然而,在SOVTE中使用狭窄的吸管可以减少语音负载和惯性力,使其成为语音制作中潜在的更安全的选择.
科学领域:
- 喉腔病理学 喉腔病理学
- 声音科学 声音科学
- 声学分析 声学分析
背景情况:
- 半闭塞语音练习 (SOVTEs) 用于修改声学参数.
- 在SOVTEs期间了解声音负载对于语音训练和治疗至关重要.
- 冲击应力 (IS) 和惯力是声生物力学的关键指标.
研究的目的:
- 量化和比较在一个元音和两个常见的SOVTE的大声发音期间的声载.
- 为了估计撞击应力和惯性力在这些发音类型期间.
主要方法:
- 在一个声音健康的男性身上进行了体内实验研究.
- 高速视频喉腔内镜捕捉了用管 (浸入水中) 和吸管 (在空气中) 发音期间的球动态.
- 测量了口腔空气压力,并分析了球关闭速度,加速和减速.
主要成果:
- 大声的SOVTEs,特别是带有管子的SOVTEs,与习惯的声音声调相比,增加了喉闭合速度和冲击应力.
- 与大声的母音发音相比,大声的SOVTE通常显示与管道的球宽度增加,但与草的宽度减少.
- 与管和大声母音相比,狭窄的吸管显著降低了惯力 (ACC,DC) 和冲击应力.
结论:
- 大声的SOVTE会增加声音负荷,但狭窄的SOVTE会导致较低的冲击应力和惯性力,而不是大声的母音发音.
- 狭窄的吸管可能通过减轻过度的声音负载,为响亮的SOVTE提供更安全的方法.
- 这些发现对优化临床和性能设置中的语音练习协议有影响.

01:25Suctioning the Oropharyngeal Airway
197
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:20Imaging Studies for Cardiovascular System II:Types of Echocardiography
247
Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
1.5K
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
72
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
363
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
