概括
在30分钟内,无论是 sigh 招募还是持续的膨胀机动都没有显著改善 ARDS 患者的呼吸机制或气体交换. 需要进一步的研究来了解这些招聘机动的长期影响.
科学领域:
- 关键护理医学 关键护理医学
- 呼吸系统生理学 呼吸系统生理学
背景情况:
- 招募机动 (RMs) 在机械通风中用于ARDS患者.
- 招聘和持续通货膨胀的相对影响尚不完全理解.
研究的目的:
- 为了比较 sigh 招募和持续膨胀对 ARDS 患者呼吸机制,气体交换和肺体积的影响.
主要方法:
- 一项随机交叉研究,涉及23名ARDS患者.
- 患者接受了叹息招募或持续膨胀RM,然后在洗期后接受另一种.
- 测量包括呼吸机制,血液动力学,气体交换和电阻断断层扫描 (EIT) 衍生的肺体积.
主要成果:
- 与基线相比,这两种RM都导致了相似的呼吸机制,血液动力学,气体交换和EIT衍生的肺体积.

The Sense of Self: Reflected Self-Appraisal and Social Comparison
56.2K
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...

Fixed 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 Tests
4.5K
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...

Evolutionary Relationships through Genome Comparisons
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...

Comparison 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...
