背景情况:
- 上呼吸道肌肉功能对于在睡眠期间保持呼吸道通透性至关重要.
- 假设舌头肌肉属性的改变有助于阻塞性睡眠呼吸暂停 (OSA).
- 之前对OSA患者舌头肌肉机制的研究已经产生了不一致的结果.
研究的目的:
- 客观地评估使用非自愿电刺激的OSA患者的舌头肌肉机制.
- 为了比较OSA患者和健康对照者之间的舌头突起力和疲劳性.
- 为了研究肌肉纤维特征和协调的潜在差异.
主要方法:
- 用表面电刺激来评估非自愿的舌头突起力,用电刺激来评估光肌 (GG) 肌肉的表面电刺激.

Sleep Apnea
483
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Suctioning the Oropharyngeal Airway
812
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...

Cardiopulmonary Resuscitation II: ACLS Airway Management
539
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Assessment of Airway, Skin Color, and Use of Accessory Muscles
1.6K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
