まとめ
RAP,shimmer,CPPのような音声測定は,モデルでの飲み安全性を予測するのに役立ちますが,それだけでは信頼できません. 騒音対和音比は有用な予測指標ではなかった.
科学分野:
- スピーチ・ランゲージ・パスロジー
- 音響分析
- 飲み込み障害
背景:
- 吸入を防ぐには 飲み込む安全性が重要です
- 飲み込む安全性を評価するには客観的な対策が必要である.
- 音声分析は潜在的に 非侵襲的なツールです
研究 の 目的:
- 音声測定が飲み込む安全性と相関するかどうかを判断する.
- 特定の音響パラメータ (RAP,シャイマー,NHR,CPP) の浸透-吸入イベントの予測値を調査する.
- 呼吸器の侵入を予測する単独の音響測定法の有効性を評価する.
主な方法:
- ビデオ光検査 (VFSS) を受けた34人の成人を対象とした前向きな研究.
- ボラスを飲み込む前と後の 音声録画
- パラットによるジッター (RAP),シャイマー,NHR,CPPによる音響分析. 浸透-吸入スケール (PAS) によって飲み込む安全性が評価された.
主要な成果:
- 飲み込む前に予想される相対平均気流 (RAP) とシャイマー (p < .05)
- セプストラルのピーク突起 (CPP) は,飲み込み後の吸血を予測する変化 (p < .05) です.
- 受信機の動作特性 (ROC) 分析は,独立した分類者としてのすべての測定値の不十分なパフォーマンスを示した (p > .05).
結論:
- 音響測定法 (RAP,シャイマー,CPP) は,多様式評価において,呼吸道侵入を予測するのに役立つ.
- これらの音響特徴は,飲み込む安全性や吸入リスクの単独の指標として不十分です.
- この研究では,ノイズ・トゥ・ハーモニック・レシオ (NHR) が浸透または吸入を予測しなかった.

Larynx
2.1K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Respiratory System Abnormal Finding II: Palpation and Auscultation
721
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Physical Assessment of the Respiratory Tract IV: Auscultation
701
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.

Physical Assessment of the Respiratory Tract III: Percussion
921
The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.
