Everyone reacts to extreme changes in altitude differently and just because you haven’t suffered on previous occasions, it doesn’t mean that you couldn’t in the future.Īge, gender or physical fitness level has no impact on your chance of getting altitude sickness. There is no telling whether you could fall victim to altitude sickness. It is worth noting that whilst many travellers to South America may be affected by the altitude, very few will develop symptoms consistent with HACE or HAPE. High Altitude Pulmonary Edema (HAPE) which is also lethal, involves fluid collecting in the lungs. During a High Altitude Cerebral Edema (HACE), the brain begins to swell. If the symptoms progress to those which affect your co-ordination, balance or speech, this is an emergency and should be treated as such. South America has some of the highest cities in the world! What are the symptoms of altitude sickness?Īlthough everyone reacts to the altitude in different ways, the most common symptoms are as follows:Įssentially, the symptoms of altitude sickness for most people resemble a bad hangover. Although very serious cases are rare compared to the number of people who suffer minor effects, altitude sickness can be very severe and in extreme cases, even lead to death. Owing to the shortage of oxygen at high altitudes, travellers can become ill. Altitude sickness medication: The verdict!Īltitude sickness is also known as acute mountain sickness (AMS).What are the symptoms of altitude sickness?.Average symptoms and severity were similar between drugs, suggesting prevention of disease.Īcetazolamide Acute mountain sickness Altitude Altitude medicine Ibuprofen.Ĭopyright © 2018. Ibuprofen was slightly inferior to acetazolamide for acute mountain sickness prevention and should not be recommended over acetazolamide for rapid ascent. The acetazolamide group had higher peripheral capillary oxygen saturation than the ibuprofen group (88.5% vs 85.6% P =. No difference was found in the total LLQ scores or subgroup symptoms between drugs (P =. The total incidence of acute mountain sickness was 56.5%, with the incidence for the ibuprofen group being 11% greater than that for acetazolamide, surpassing the predetermined 26% noninferiority margin (62.2% vs 51.1% 95% confidence interval, -11.1 to 33.5). This trial was registered at : NCT03154645 RESULTS: Ninety-two participants completed the study: 45 (49%) on ibuprofen and 47 (51%) on acetazolamide. Sleep quality and headache severity were measured with the Groningen Sleep Quality Survey (GSQS). The main outcome measure was acute mountain sickness incidence, using the Lake Louise Questionnaire (LLQ), with a score of >3 with headache. Although previous studies of ibuprofen have shown efficacy for the prevention of acute mountain sickness, recommendations have been limited, as ibuprofen has not been compared directly with acetazolamide until this study.īefore their ascent to 3810 m on White Mountain in California, adult volunteers were randomized to ibuprofen (600 mg, 3 times daily, started 4 hours before the ascent), or to acetazolamide (125 mg, twice daily, started the night before the ascent). Acute mountain sickness is a common occurrence for travel to high altitudes. ![]() An only child, she was shunted between a bewildering number of boarding schools. ![]() She made the first of her "escapes" when she was 18, turning up on the doorstep of her old nurse in her childhood city of Montreal, leaving her mother in New York. Gallant's life seems richer in stories than most. "I could only stop myself by saying: 'It's only a story, pull yourself together.'" She recalls how, reading one of her stories, "The End of the World", to a group of bored schoolchildren, she started to cry because she had forgotten the ending and suddenly realised one of the characters was going to die – and her eyes, just a minute before creased with laughter, fill with tears across the table. Her osteoporosis is forgotten (sitting for long periods, and even writing, are painful) as figures from her past, or characters from her fiction – both seemingly as real to her as each other – are recollected and reanimated. She is pin sharp: if you aren't careful, and push for direct answers, the stories burst in your face. Indeed, the life and work seem almost indistinguishable: she speaks in a succession of stories, as effortlessly as bubbles blown through a loop, smaller tales attached to larger ones. "I have lived in writing, like a spoonful of water in a river," she writes in the introduction to her Selected Stories. Now 87, she is a famous regular herself the only time she is unable to secure her own spot – the cosy "Picasso booth" – is when Paloma, the artist's daughter, is in town. Can you imagine – the French giving anything away free!" she says, her handsome face crumpled by a chuckle. "It was a terrible winter and I used to come here because it was warm and I didn't have any electricity in my apartment. She first came to the restaurant when she arrived from Montreal in 1950. We meet in Le Dôme, a notorious hangout for writers and artists in bohemian Montparnasse and long a favourite with Gallant, who lives what used to be for her just a nip around the corner, but is now – due to increasing frailty – a short taxi ride away. "Only personal independence matters," she once wrote, quoting Boris Pasternak, and this might well be her motto. She has travelled extensively, usually alone, across Europe. Reading too many of her stories at one time leaves the reader feeling strangely adrift, the world slightly askance. A Canadian in Paris who has devoted her life to writing, she is one of the great chroniclers of exile, her fictional landscapes inhabited by misfits and lost souls, characters far from home, literally or emotionally. "They were all in a strange land and out of context," one of the characters reflects in Green Water, Green Sky, Gallant's first (of only two) novels, written in 1959. You can also find the user’s manual and a reference manual on the site. If you are trying to learn the program, there are some starting instructions for an older version that should get you the basics. True, we expect there won’t be future development, but the package seems very complete and with the ability to import models, it will be very useful for a long time to come. However, we appreciate the free release of this powerful simulator that can give LTSpice a run for its money. We don’t know the circumstances of Spectrum’s closing but we hope it was to move on to something great. The software was under development since 1982. We wish it would work with KiCAD, although we are pretty sure you could figure out some conversion path from one of the formats available. Over 18,000 components in the library have packages available and there is a package editor. One other feature we liked is that the program can output a netlist for printed circuit board programs including Protel, Accel, Orcad, and PADS. This is especially useful if you are stepping parameters or measuring the effect on parameter variation like temperature. You get a nice colored graph that tells you how close you are to smoke or, if you have some red bars, what parts will smoke.Īnother neat feature is that you can create very cool 3D plots. The idea is to run a transient analysis and the program determines if any circuit values exceed the maximum value for a component. With this software, you can set ranges for various circuit components, tell the program what you want to optimize, and it will compute the best values for you. We frequently use Spice when we are too lazy to do the math required to pick an optimal set of values. One nice touch is that you can view a simulation and interactively change component values and watch the results update right away. You can, however, select “large toolbar” on the Options | Preference menu, which will help. On a big monitor, you might want to use Winecfg to set a higher DPI setting, although the toolbar icons are fixed in size which is a little inconvenient. The 64-bit one would probably work with a little effort. ![]() There are also over 2,000 standard digital parts including all the usual 7400 families, CD4000 CMOS, and even ECL.Īs a bonus, we tried it under Wine and it worked well - at least the 32-bit version. There are also quite a few examples provided. ![]() ![]() It can also export Spice files if you want to use another engine or share designs with other Spice users. It can also read just about any regular Spice or IBIS model. The number of models supported for active devices is impressive and includes some very recent MOSFET models, not just the old standard models. Have a look at the brochure and you will see this is a pretty serious piece of software. There’s a built-in designer for active and passive filters. The simulator boasts a multipage schematic editor, native robust digital simulation, Monte Carlo analysis, 33,000 parts in its library, worst-case and smoke analysis, Smith charts, and it can even incorporate spreadsheets. You may be thinking: why use another closed-source simulator? Well, all the simulators have particular strengths, but Micro-Cap does have very nice features and used to retail for about $4,500. However, there is a new free option after the closing of Spectrum Software last year: Micro-Cap 12. If you are looking for simulation software, you are probably thinking LTSpice or one of the open-source simulators like Ngspice (which drives Oregano and QUCs-S), or GNUCap. |
