概括
对神经障碍儿童的机械吸气-排气 (MI-E) 策略表明,与对称方法相比,不对称或个性化的设置改善了用户舒适度,但减少了咳峰值流量. 所有方法都保持了治疗性咳流.
科学领域:
- 儿科肺病学 儿科肺病学
- 生物医学工程 生物医学工程
- 康复医学 康复医学 康复医学
背景情况:
- 机械吸气-排气 (MI-E) 对于增加神经障碍儿童咳至关重要.
- 优化MI-E设置对于提高患者舒适度和治疗疗效至关重要.
- 了解影响舒适度和咳有效性的因素是临床实践的关键.
研究的目的:
- 评估神经障碍儿童的三种不同的MI-E策略的用户舒适度和峰值咳流量 (PCF).
- 为了确定MI-E治疗期间增强舒适度和咳流量的预测因素.
- 为了比较对称,不对称和个性化的MI-E设置.
主要方法:
- 一个多中心的交叉试验,涉及74名神经障碍儿童,使用长期MI-E通过面具.
- 对三种MI-E策略进行随机测试:A-对称 (±50cmH2O,In=Ex),B-不对称 (+25/+30cmH2O,-40cmH2O,In>Ex) 和C-个性化.
- 主要结局包括视觉模拟尺度 (VAS) 舒适度得分和用气动图谱测量PCF.
主要成果:
- 与B非对称 (2.9±2.44) 和C个性化 (3.2±2.46) (p<0.001) 相比,A对称策略 (±50 cmH2O) 的舒适度得分 (VAS 4.7±2.96) 显著更高.
- 与B-非对称 (166±46.05) 和C-个性化 (171±49.74) (p<0.001) 相比,A对称策略 (203±46.87 L·min-1) 的PCF最高.
- 较低的吸气流预测了改善的舒适性,而老年和更高的无助咳流与增加的排气流相关.
结论:
- 非对称或个性化的MI-E策略提高了用户的舒适性,但与高压对称方法相比,可能会减少咳峰值流量.
- 所有测试的MI-E策略都实现了超过治疗值的咳流量.
- 尽管MI-E被评为轻微至中度不舒服,但它仍然是增加该人口咳的重要干预措施.

Chronic Obstructive Pulmonary Disease-V: Nursing Management
3.9K
Nursing management of Chronic Obstructive Pulmonary Disease (COPD) is crucial for providing thorough care and support to patients. Nurses play an integral role in this process through detailed assessment, careful planning, targeted interventions, and ongoing evaluation. Here's an overview of the critical steps in nursing management for COPD.

Pneumonia V: Nursing management and Prevention
2.1K
Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
288
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

Ventilatory Modes
157
Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Acute Respiratory Failure-V
141
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Mechanical Ventilation II: Invasive Ventilation
144
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...
