- 临床试验研究 临床试验研究
背景情况:
- 在早产婴儿中停止持续正气道压力 (CPAP) 的最佳时间尚未确立.
- 间歇性低血 (IH) 和呼吸系统不稳定是CPAP断奶期间常见的担忧.
- 这项研究研究了一种替代的断奶策略,以减轻这些风险.
研究的目的:
- 为了比较扩展CPAP与低流量鼻 (NC) 断奶在减少IH和呼吸系统不稳定的有效性.
- 评估CPAP扩展对早产婴儿二次呼吸和氧化参数的影响.
主要方法:
- 一个单一中心随机临床试验,涉及36名早产婴儿 (<34周怀孕),符合CPAP停止标准.
- 婴儿被随机分配到延长CPAP或断奶到低流NC24小时.
- 主要结局是IH发作的次数 (SpO2 ≥10s<85%);次要结局包括SpO2变化,氧化和心.
主要成果:
- 与NC组相比,CPAP组的IH发作显著减少 (中位数为20对76每24小时;p=0.03).
- 接受延长CPAP治疗的婴儿表现出降低了胸肌梗塞,SpO2<91%和<85%的时间更短,FiO2需求更低 (所有p<0.05).
- 在IH<80%,通过皮肤的CO2或脑/脏氧化量之间没有观察到显著差异.
结论:
- 延长的CPAP显著降低了准备停止CPAP的早产婴儿间歇性低血和心.
- 这一策略在24小时的干预期内提供了潜在的好处,而不是在24小时的干预期内立即断奶到低流量鼻.
- 进一步的研究可能会探索CPAP延长的长期结果和最佳持续时间.

Administering Oxygen by Nasal Cannula
551
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

Oxygen Delivering System I: Nasal Cannula and Face Mask
324
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Mechanical Ventilation III: Noninvasive Ventilation
115
Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
580
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
214
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
