まとめ

呼吸器の膨張 (VHI) と手動胸部圧縮 (MCC) は,機械的に呼吸する患者の呼吸道清掃に有効です. VHIは,分泌物の除去を損なうことなく,流れのダイナミクスの改善のような利点を提供します.

科学分野:

クリティカルケア医療
呼吸器療法

背景:

呼吸器で呼吸する患者の分泌の蓄積は肺機能を阻害し,感染リスクを高める.
手動胸圧縮 (MCC) と呼吸器の膨張 (VHI) は,呼吸道浄化技術ですが,直接的な比較は欠けている.

研究の目的:

VHIとMCCの効果を機械呼吸器で呼吸する成人の分泌クリアランスと比較する.
呼吸力学と血液動力学的安定性を含む二次結果の評価.

主な方法:

ランダム化クロスオーバー試験で,機械呼吸器を施した44人の成人のICU患者を対象とした.
VHIとMCCの両方,ランダムに投与され,4時間の洗い流し期間が与えられました.
主要評価項:除去された唾液の量副次評価項:最大排気流量,肺の適合性,血液動力学

主要な成果:

MCCと比較して,VHIはピーク吐出量と吐出量バイアスを有意に増加させた.
VHIとMCCの間に除去された唾液の量において,有意な違いは認められなかった.
両方の方法は,血圧,心拍数,酸素飽和度,および肺の適合性に比較可能な効果を示した.

結論:

VHIは,機械呼吸器患者の呼吸道クリアランスのMCCに劣らない.
VHIはフローダイナミクスを改善し,臨床医の身体的ストレスを軽減するなどの利点を提供します.
VHIは,集中治療施設での呼吸道クリアランス治療の安全で実用的で効率的な代替手段です.

Mechanical Ventilation II: Invasive Ventilation

253

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...

Mechanical Ventilation I: Indication and Settings

932

Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Mechanical Ventilation III: Noninvasive Ventilation

224

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.

Ventilatory Modes

431

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...

Pulmonary Ventilation: Inhalation

4.7K

Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.
Boyle's law becomes particularly pertinent when examining respiratory...
