We evaluated 48 models of LSE, including goggles, spectacles, and wraps, from 11 manufacturers. The evaluated models are designed with absorptive lenses that provide protection from CO2 (carbon dioxide), Nd:YAG (neodymium:yttrium-aluminum-garnet), and 532 (frequency-doubled Nd:YAG) surgical laser wavelengths; several models provide multiwavelength protection. (Refer to ECRI's Product Comparison System report on LSE for specifications of other models.) Although most of the evaluated models can adequately protect users from laser energy--provided that the eyewear is used--many models of LSE, especially goggles, are designed with little regard for the needs of actual use (e.g., adequate labeling, no alteration of color perception, sufficient field of vision [FOV], comfort). Because these factors can discourage people from using LSE, we encourage manufacturers to develop new and improved models that will be worn. We based our ratings primarily on the laser protection provided by the optical density (OD) of the lenses; we acknowledge the contribution of Montana Laser Optics Inc., of Bozeman, Montana, in performing our OD testing. We also considered actual-use factors, such as those mentioned above, to be significant. Among the models rated Acceptable is one whose labeled OD is lower than the level we determined to be adequate for use during most laser surgery; however, this model offers protection under specific conditions of use (e.g., for use by spectators some distance from the surgical site, for use during endoscopic procedures) that should be determined by the laser safety officer (LSO). LSE that would put the wearer at risk are rated Unacceptable (e.g., some models are not properly or clearly labeled, have measured ODs that are not adequate for protection, or significantly restrict the wearer's FOV); also, LSE with side shields that do not offer adequate protection from diffuse laser energy are rated Unacceptable. Those models that offer adequate protection for surgical applications, but whose measured OD is less than their labeled OD, are rated Acceptable--Not Recommended; if the discrepancy is great, they are rated Unacceptable. Those models whose labels were removed during cleaning are rated Conditionally Acceptable.(ABSTRACT TRUNCATED AT 400 WORDS)","PeriodicalId":77154,"journal":{"name":"Health devices","volume":"22 4 1","pages":"159-204"},"PeriodicalIF":0.0,"publicationDate":"2022-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43705051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, Nakamoto-style blockchains possess several characteristics that make them inappropriate for many purposes in the Internet of Things (IoT) domain. Notably, they are powerintensive and require high network connectivity. These requirements are fundamentally incompatible with IoT where nodes may have limited power and sporadic network access. We are designing a blockchain approach for IoT environments called Vegvisir. Vegvisir is a partition-tolerant blockchain for use in power-constrained IoT environments with limited network access. Under the hood, it is a membership-based, directed acyclic graph (DAG)-structured blockchain [1]. It is motivated by and ideally suited for paramedics and firefighters in disaster scenarios. For instance, it can be used to aid in many tasks during disaster response where network connectivity is poor or nonexistent; namely, it is a blockchain, so provides the abstraction of an append-only log of transactions that is tamperproof.

I use a flow rate of 5 L-min ~ for preoxygenation and on termination of the anaesthetic. To diminish the diluting effect &the added flow of oxygen to the inspired concentration of halothane, I reduce the oxygen flow to 1 L.min -l during maintenance of anaesthesia. This conserves our supply of halothane, also a costly item in this part of the world. The Haloxair ~ has an oxygen flowmeter calibrated from 1-3 L.min -I to which a cylinder of compressed gas can be connected. I keep a cylinder attached, in case of power failure. The types of cases done at our hospital using this simple circuit include an oesophagectomy, laparotomy for ruptured ectopic pregnancy, Caesarean section, and repair of an oomphalocele in a newborn. It has also been a means of using oxygen in the resuscitation of newborns, children, and adults. There have been no clinical signs of hypoxia. I feel that in remote areas where use of the Haloxair ~ is appropriate and cylinders of oxygen are not readily obtainable but electricity is available, the use of an oxygen concentrator in conjunction with the Haloxair ~ adds an immeasurable margin of safety and offers a very satisfactory method of giving general anaesthesia.","PeriodicalId":77154,"journal":{"name":"Health devices","volume":"74 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/9781119277187.ch2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50762970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
