This may produce high Ppl, which might overdistend vulnerable lung regions. In respiratory failure, when PEEP is set, the tidal volume (when using pressure controlled ventilation) or the airway pressure above PEEP (when using volume controlled ventilation) are not adjusted. A patient with very low compliance (e.g., ARDS) would be expected to have a lower alveolar volume at the same Ppl level (35 cmH 2O) and hence to be at lower risk of barotrauma. A patient with emphysema (high lung compliance) and elevated Ppl (35 cmH 2O) would be expected to have a large end-expiratory alveolar volume and thus be at risk of barotrauma. Certainly, the volume is related to the pressure by the compliance characteristics of the lung and chest wall. The Ppl and more correctly the transpulmonary pressure (Ppl-Ppleural) reflect the compliance of the respiratory system, given the initial PEEP level and the delivered tidal volume and gauge the maximum alveolar pressure and hence maximal alveolar volume. This Ppl is the pressure applied to the small airways and alveoli. In volume control modes of ventilation, when the Ppk reaches its maximum value, there is a rapid drop of the pressure until a plateau is reached (plateau pressure-Ppl). It increases with hyperinflation, but it has no pathological value in the clinical setting, since it arises from the increased airway resistance and the high inspiratory flow rate and is mainly dissipated in the airways and thus does not reach the alveoli. The peak airway pressure (Ppk) is the pressure measured by the ventilator in the major airways and it strongly reflects airway resistance. In each case hyperinflation occurs when the inspired air cannot be totally expired (dynamic hyperinflation) ( 20- 29).Īll forms of pressure are not equal as barotrauma aetiologic factors. This suggests that risk factors predisposing to barotrauma are a severe underlying lung disease, which seriously affects alveoli and all factors predisposing to hyperinflation: high transpulmonary pressure (airway pressure minus the pleural pressure), high tidal volumes, high intrinsic PEEP. In case of mediastinal parietal rupture pneumothorax is appeared.Īll barotrauma forms come from rupture of a hyperinflated alveolus and air leak into the surrounding tissues and spaces. The air can be decompressed both retroperitoneally and intraperitoneally (pneumoperitoneum). When adequate air is accumulated in mediastinum, it is decompressed along cervical fascial planes into the subcutaneous tissues and subcutaneous emphysema is formed. Air can be introduced along the perivascular sheaths into the mediastinum and pneumomediastinum or pneumopericardium are present. When an overdistended alveolus ruptures, air is diffused into the perivascular adventitia, resulting in PIE. The two terms-barotrauma and volutrauma-reflect the two sides of the same phenomenon: the lung injury due to a large distending volume and/or to a high airway pressure ( 10- 19).Ĭlinical manifestations of barotrauma include pneumothorax, pulmonary interstitial emphysema (PIE), subcutaneous emphysema, pneumoperitoneum, pneumomediastinum or pneumopericardium, air embolisation, tension lung cysts, and hyperinflated left lower lobe. Volutrauma is the term that describes ultrastructural lung injury due to overdistention occurring during mechanical ventilation. Nevertheless, it seems that not only pressure, but high lung volume and lung hyperinflation as well, play a major role in barotrauma aetiology. According to the etymology, barotrauma refers only to high pressures. VALI and VILI can be divided into macrobarotrauma (the form of radiologically detected barotrauma) and microbarotrauma, with diffuse lung injury and possible injury of other organs due to release of inflammatory mediators-biotrauma. ![]() This is described as ventilator associated lung injury (VALI) or ventilator induced lung injury (VILI). The implementation of positive pressure ventilation predisposes an already affected lung-when certain limits are overcome-to injury. It is defined as the presence of extraalveolar air in locations, where it is not normally found in patients receiving mechanical ventilation ( 1- 9). Barotrauma must be considered as complication of the use of positive pressures in a tissue, where normal air movement is mainly passive. While human being is created, as other creatures, to breathe with a mechanism based on negative pressures, the patient on mechanical ventilation is ventilated with positive pressures, which is not physiological. ![]() Intubation and mechanical ventilation are common but aggressive therapeutic manoeuvres in anesthesia or in ICU setting.

JPGs work well in both digital and print formats, but they aren’t lossless like PNGs. You can choose how much you want to drop the image’s quality which, in turn, makes the image’s filesize smaller. JPG files, unlike PNG files, are compressed, which creates some degree of image quality loss. Essentially, PNG files are designed to look great on computer monitors and smartphones, not on paper. PNG files lack certain attributes that would make them good to use for print, specifically lacking support for CMYK color spaces.

![]() In 1791, the French parliament imposed the use of the metric system on the country, and it is now used in Continental Europe and many other parts of the world. Metric weights, the gram, the kilogram, were developed by scientists in 18th century France. Metric weights have a very different history. A standards bureau was set up with prototypes for the imperial system at that time. In 1855, a fire destroyed the Houses of Parliament in London, where the standards for these weights were kept. The system came into official use across the British Empire. This system of units was first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. This measure has come down to us as part of the British Imperial System of Weights and Measures, which is also used in the U.S. The Dirhem was halved to 222 grains for the penny, twenty of which made the ounce as before, and twelve ounces the pound in silver. Translated into English as the 'ounce,' King Offa, who lived at the end of the 8th century, accepted the silver ounce but then ran short of silver. Ten Dirhems made a Wukryeh of 450 grains, which we call an ounce from the Latin "uncia" or twelfth, which name is used genetically for such a class of weight or volume. The uncia is a twelfth part of the 'pes,' which is the Roman 'foot -' our word inch is also derived from 'uncia.' The Romans used the same word for ounce, which they measured using a technique taken from the Arabs.įor the Arabs, a silver Dirhem was determined by 45 full grown barley grains. ![]() Their basic unit of weight was the 'uncia,' from which the English word 'ounce' is originally derived. The Greeks used the same weight measurement as the Babylonians, but the Romans changed it. It was equal to the amount of water that filled an amphora (a kind of vase). The Babylonians invented the talent, as the basic unit of weight, and, based on their sexagesimal (60-based), divided into equal parts in terms of that number. For instance, the "carat," still used as a mass unit for gems, is derived from the carob seed. ![]() With the development of scales as a means of weighing, seeds and stones served as standards. These were filled with plant seeds that were then counted to measure the volumes. Why We Have Different Ways to Measure Weight?Įarly Babylonian and Egyptian records, as well as the Bible, indicate that weight was originally measured by the capacities of containers such as gourds or clay or metal vessels. Now let's take and example of how to convert kilograms into pounds. To convert kilograms into pounds, just divide the kilogram figure by 0.45359237 ![]() Formula of Converting Kilograms into Pounds One pound is divided into 16 ounces (oz). In short form, pound is written as lb and one kilogram is equal to 2.20462262185 lbs. Pound is the imperial and USA customary unit of weight. If you have some weight figures in kilograms and you need the same figures in equivalent pounds, you can use this converter. The Imperial or USA customary unit for the measurement of weight (or mass) is pound. Similarly, in UK the Imperial units are used. United States of America uses the customary units of measurement.

![]() This did not impact our rating, however, because we would not establish a reprinting agreement with an outlet we felt was not evidence-based.Visitors are drawn by scientific experiments on display at the 19th Public Science Day event in Beijing on Saturday. (2) Full disclosure: ACSH and RCS have a reprinting agreement with LiveScience. (1) Here is a list of ten tips to help you detect fake news. Even a broken clock is correct twice per day. If they ever report something truthful, it is almost certainly by accident. The biggest purveyors of fake science news are Natural News, Mercola, The Food Babe, and InfoWars. Any science news reported here should be verified for accuracy. While CNN, Fox News, and MSNBC might be useful for other things, they are mostly awful sources of science news. Not a single cable news source is worth your time. News sources like the Daily Mail and The Telegraph serve up a disproportionate amount of sensationalist garbage. If it wasn't for the fact that some respectable writers like John Tierney and Carl Zimmer also publish there, the NYT's science coverage would be comparable to that of the Huffington Post.īeware British tabloids. The NYT regularly reports false information on GMOs and agriculture, perhaps none so egregious as this utterly abominable article by Danny Hakim that compared pesticides to Nazi-made sarin gas. It also published a story on a fake disease called post-treatment Lyme disease syndrome. The paper promotes dubious fad diets, cited the quack Joe Mercola on a story about the safety of wearable electronics, and gives voice to organic foodies. The NYT - America's alleged newspaper of record - has itself quite a record of unscientific transgressions. (Previously, that dubious distinction went to ScienceBlogs, but nobody reads that anymore.) SciAm's best content is generally stuff they reprint from other outlets. What's wrong with Scientific American? For a long while, Scientific American became the headquarters for left-wing social justice warriors and others who felt bashing conservatives was more important than reporting good science. It is very serious and well reported, but the topic selection is esoteric and of interest to few people. While some of their content is good, our biggest problem with them is that they are prone to wide-eyed speculation and clickbait rather than serious science news analysis. No love for Popular Science and Wired? They're okay. NewScientist and Live Science are perfect for true science geeks. The Economist is excellent for people who are mostly interested in global news and politics but have a curiosity for science. The best of the best. By far, the two best sources of science news (besides ACSH and RealClearScience, of course!) are Nature and Science, both of which have news sections aimed at the general public. Here are more detailed explanations for a few specific choices 2: (RealClearScience also has its own analysis of this infographic.) (By "poorly reported," we mean either the topic selection is dull or the content is mostly fluff or sensationalism.) Outlets toward the bottom are of limited interest or are poorly reported. Outlets toward the top are of broad general interest and are well reported. On the Y-axis (from top to bottom), we rank media outlets based on whether they are compelling sources of information. Evidence plays little to no role for these outlets. ![]() Sources in the red column, on the other hand, are driven by ideology and are characterized by lopsided reporting. Media outlets in the green column produce scientific content that is based on evidence and is largely free of ideology. On the X-axis (from left to right), we rank sources by their fundamental trustworthiness. Some journalists really do care about reporting the news as it is rather than the way they would like it to be. So, in an effort to promote good science news sources while castigating the bad, we teamed up with RealClearScience to create an infographic. One thing experience has taught us is that some news outlets are better than others. Every week, it seems, an everyday food is either going to cure cancer or kill us all. Not only is it susceptible to the same sorts of biases that afflict regular journalism, but it is uniquely vulnerable to outrageous sensationalism. If journalism as a whole is bad (and it is), science journalism is even worse. It helps to be well informed, and it requires a conscious suspension of credulity combined with a gut instinct honed over years of experience. ![]() ![]() A common question I hear again and again is, "How do I know if a news story is fake?"

Swimming against those historical tides, Biden traveled Thursday to Syracuse, New York, for a rare appearance in a competitive congressional district. That’s considerably higher than his ratings in 2010, when Democrats lost control of the House in a midterm election that Obama called a “shellacking.” In his second midterm election four years later, the GOP regained control of the Senate. Obama left office in January 2017 with a 59% approval rating, and Gallup measured his post-presidential approval at 63% the following year, the last time the organization surveyed former presidents. “Barack Obama is the best messenger we’ve got in our party, and he’s the most popular political figure in the country in either party,” said Bakari Sellers, a South Carolina Democrat and prominent political commentator.
