まとめ
視線徴募も持続的な膨張操作も30分以内にARDS患者の呼吸器のメカニズムやガス交換を有意に改善しませんでした. これらの採用マニュアルの長期的な効果を理解するために,さらなる研究が必要である.
科学分野:
- クリティカルケア・メディシン
- 呼吸器生理学 呼吸器生理学について
背景:
- リクルートマニュバー (RM) は,ARDS患者の機械呼吸器に使用されます.
- Sighの採用と持続的なインフレのRMの比較効果は完全に理解されていません.
研究 の 目的:
- ARDS患者の呼吸器メカニズム,ガス交換,肺の容量に対する sigh recruitmentと持続的な膨張の効果を比較する.
主な方法:
- 23人のARDS患者を対象としたランダム化クロスオーバー研究.
- 患者は, sigh recruitment または sustained inflation RM を受け,その後は,ウォッシュアウト期間を経て,別のRMを受けました.
- 測定には,呼吸器の力学,血液動力学,ガス交換,および電気阻力トモグラフィ (EIT) による肺体積が含まれていました.
主要な成果:
- 両方のRMは,ベースラインと比較して同様の呼吸器のメカニズム,血液動力学,ガス交換,およびEIT由来の肺容量をもたらしました.
- RM後30分以内にこれらのパラメータにおいて臨床的に有意な改善は見られなかった.
- 患者の少数の割合では,PaO2/FiO2比率が一時的に上昇した.
結論:
- sigh recruitment と sustained inflation のいずれも,ARDS患者の呼吸器メカニズム,ガス交換,または肺容量に臨床的に有意な短期的な影響を示さなかった.
- この研究は,これらの特定のRM戦略の限られた直接的な利点を示唆しています.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

01:06Fixed Action Patterns
17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

7.1K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

01:24Comparison Between Electrical And Gravitational Forces
4.1K
There are four fundamental forces in nature: the gravitational force, the electromagnetic force, the strong nuclear force, and the weak nuclear force. To compare the numerical strengths of the first two, take two particles of the same kind. Since electrons are fundamental particles, they are a good example.
Since both are inverse square law forces, the distance gets canceled when the ratio of the two forces is considered. Instead, the ratio of the electrical and gravitational forces depends on...
