まとめ
肺の超音波検査は,機械呼吸器を用いる患者の肺の換気を効果的に評価します. 肺の超音波スコア (LUS) によって確認されたように,陽性終息圧 (PEEP) の増加は肺の空気と酸素の供給を改善します.
科学分野:
- クリティカル ケア 医療
- 肺科
- 医療用イメージング
背景:
- 肺超音波検査 (LUS) は,機械呼吸器を用いる患者でますます利用されている.
- LUSは,陽性終息圧 (PEEP) 調整および機械的換気離乳時の肺空気を評価するのに役立ちます.
- PEEPが肺の換気に与える影響は,異なる病態によって変化し,常にLUSと相関しない場合があります.
研究 の 目的:
- 肺空気を評価する際に肺超音波の役割を決定する.
- 肺の様々な病態を持つ機械呼吸器を施す患者のPEEP施用中の肺空気を評価する.
主な方法:
- 高等医療病院での18ヶ月の観察研究
- 機械呼吸器を必要とする18歳から75歳のICU患者も含む.
- 付加 PEEP レベル (5,10,15 cm H2O) を適用し,SpO2,LUS,MAP,HR を記録した.
主要な成果:
- 患者の45. 9%が5cmのH2OPEEPで肺のエアレーションエンドポイントを達成した.
- 86. 5% と 13. 5% が,それぞれ 10cm H2O PEEP で終点に達した.
- PEEPを増加させると SpO2と肺の換気量 (LUSの減少) が有意に改善したが,HRは増加し,MAPは減少した.
結論:
- 高濃度のPEEPは,機械呼吸器を用いる患者の肺の換気を高めます.
- ベッドサイドの肺超音波検査は,PEEPによって引き起こされる肺の換気変化を評価するための効果的なツールです.

Assessment of Respiration
1.3K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Respiratory System Abnormal Finding I: Inspection and Percussion
429
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Mechanical Ventilation I: Indication and Settings
922
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...

Physical Assessment of the Respiratory Tract III: Percussion
933
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.

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
