2024年9月19日 · This 6CIT score calculator screens for dementia and other cognitive impairments with satisfactory sensitivity and specificity.

Score: the 6CIT uses an inverse score and questions are weighted to produce a total out of 28. Scores of 0-7 are considered normal and 8 or more significant. Advantages: the test has high sensitivity without compromising specificity, even in mild dementia. It is easy to translate linguistically and culturally. Page 1 of 2

2022年1月9日 · A score of eight or more is normal, 6-7 suggests possible cognitive impairment, and 0-5 suggests probable cognitive impairment. 6-item Screener. This is comprised of three temporal orientation questions (year, month, day of the week) and a three-word recall. Each correct response scores one point for a total maximum of six points.

(6CIT - Kingshill Version 2000, Dementia screening tool) Ask - What year is it? Ask - What month is it? Say - Give the patient an address phrase to remember with 5 components, eg John, Smith, 42, High St, Bedford. Outcome from Score. Reference: An article from the geriatric medicine section of GPnotebook: Six Item Cognitive Impairment Test (6CIT).

2017年9月1日 · We found that 4AT scores of 0 or 1 effectively ‘rule out’ dementia; only 30% of 4AT-screened older ED attendees require further cognitive assessment, mainly for suspected delirium (7.5% screened positive for CI). Reducing the cut-off to 0/1 improves sensitivity, but increases the workload (50% now require further testing) and reduces the PPV.

AT变速箱融合了机械传动和液压传动，采用了 液力变矩器 + 行星齿轮组 以及电控的换挡结构，可以承受更大的扭矩，而CVT变速箱即无级变速，不受挡位的影响，完全靠一根钢带与主从动轮连接实现速比的无极变化，因此它的传动效率更高，但承受的扭矩却不及AT变速箱.。 由于二者所承受的扭矩不同，这也导致了这两款变速箱所应用的车型不一样。 搭载6AT变速箱的车所承受的扭矩非常强大，这也导致了很多越野车普遍使用AT变速箱，即便是负载再大，对于AT变速箱而言都 …

The score range is 0–12, with scores of 4 or more suggesting possible delirium. Scores of 1-3 suggest possible cognitive impairment. There are several indications of a positive score of 4 or more. Parameters [1] and [4] can each individually trigger a positive score.

换挡平顺性方面，6at比4at有明显的优势：车辆行驶中升挡或者减档时，发动机的转速会急剧下降或者升高，档位少的会比较明显，档位多则会把急剧下降或上升的转速平分下来，这样就保证了换挡的平顺性，减少顿挫感。

传动比范围简单点说就是利用最低挡位的齿比去除最高挡位齿比，相除后得出的结果就是传动比，而挡位更多的变速箱所得出的结果必然更大，因为更多的挡位可以将最高挡位的齿比做的更低；如上图所示分别为通用的6at、通用的9at、采埃孚的9at，传动比范围 ...

2020年2月17日 · 比如某款车型的发动机最佳工作区间是1500-3000转/分钟，当我们以100公里/小时车速行驶时，如果是6at，它的发动机转速可能是2400转/分钟；如果是9at，那么发动机转速可能就只有1800转/分钟了。
