“…The outcomes of 2818 cardiac arrest patients were examined in this meta-analysis, of which 1395 patients pertained to the mechanical group [LUCAS (908 patients); AutoPulse (487 patients)] and 1423 to the manual group. Eligible studies included seven trials 16,25,26,[35][36][37]39 comparing LUCAS with manual CPR, and three trials 28,34,38 evaluating AutoPulse vs. manual CPR. Koster et al 27 was the only study evaluating LUCAS, AutoPulse, and manual CPR simultaneously.…”

“…Koster et al 27 was the only study evaluating LUCAS, AutoPulse, and manual CPR simultaneously. Six 16,25,28,35,37,38 of the included studies had used the autopsy method and PMCT had been used in three studies 34,38,39 to explore injuries, while two others 27,36 examined the safety of chest compressions by combined means.

Safety of mechanical and manual chest compressions in cardiac arrest patients: A systematic review and meta-analysis

Aim: Summarise the evidence regarding the safety of mechanical and manual chest compressions for cardiac arrest patients.Methods: Two investigators separately screened the articles of EMBASE, PubMed, and Cochrane Central databases. Cohort studies and randomized clinical trials (RCTs) that evaluated the safety of mechanical (LUCAS or AutoPulse) and manual chest compressions in cardiac arrest patients were included. A meta-analysis was performed using a random eects model to calculate the pooled odds ratios (ORs) and their 95% confidence intervals (CIs). The primary outcome was the rate of overall compression-induced injuries. The secondary outcomes included the incidence of life-threatening injuries, skeletal fractures, visceral injuries, and other soft tissue injuries. Results:The meta-analysis included 11 trials involving 2818 patients. A significantly higher rate of overall compression-induced injuries was found for mechanical compressions than manual compressions (OR, 1.29; 95% CI, 1.19-1.41), while there was no significant dierence between the two groups in respect of the rate of life-threatening injuries. Furthermore, both modalities shared similar incidences of sternal fractures, vertebral fractures, lung, spleen, and kidney injuries. However, compared to mechanical compressions, manual compressions were shown to present a reduced risk of posterior rib fractures, and heart and liver lesions. Conclusions:The findings suggested that manual compressions could decrease the risk of compression-induced injuries compared to mechanical compressions in cardiac arrest patients. Interestingly, mechanical compressions have not increased the risk of life-threatening injuries, whereas additional high-quality RCTs are needed to further verify the safety of mechanical chest devices.

“…Normally utilized lossless compression techniques incorporate Huffman coding, LZW coding, arithmetic coding, bit-plane coding, etc [12]. The LUCAS™2 is a completely pneumatic automatic device that is outfitted with a drag for compression and a suction cup for dynamic decompression and should be appropriately set in the central breast region [2]. Combining quad-tree system, neighbor look and asymptotic procedure is necessary to execute a quick coding strategy.…”

Reduction in file size leads to reduction in the number of bits required to store it. When data is compressed, it must be decompressed into its original form bit for bit. Compound images are defined as images that contain a combination of text, natural (photo) images and graphic images. Here, compression is the process of reducing the amount of data required to represent information. Image compression is done on the basis of various loss and lossless compression algorithms. This research work deals with the preprocessing and transformations used to compress a compound image to produce a high compression ratio (CR), less compression time and so on. In the compression process the images are considered for preprocessing and discrete wavelet transform with adaptive particle swarm optimization process. The purpose of this optimization technique is to optimize the wavelet coefficient in Harr wavelet for improving the CR value. In the image compression process, run length coding is used to compress the compound images. Based on this technique, it produces minimum CR and less computation time of compound images.
