Although pH testing is useful in determining tube placement antimicrobial vs antibiotic discount 400 mg noroxin with amex, there is some controversy about which method of monitoring pH is better: use of a continuous intragastric electrode or measurement of the pH of tube aspirates with a pH meter or pH paper antibiotic resistance human microbiome buy cheap noroxin 400 mg online. Intragastric monitoring with a pH probe attached to virus 89 buy discount noroxin 400 mg on-line the end of a feeding tube can assist in both tube placement and monitoring of acid suppression therapy for several hours antibiotic resistance and public health noroxin 400mg. These probes are technically simpler and faster and may be more accurate than testing gastric aspirates with pH paper (33, 36). Intragastric pH monitoring is capable of continuously monitoring pH changes of the gastric contents, but this pH may not reflect the actual pH at the mucosal cell surface (37). Therapy to raise the pH content of gastric contents based on gastric aspirates may vary significantly from intragastric pH, overestimating the true intragastric acidity, and guide therapy changes that may not be sufficiently protective. This hypothesis is supported by case reports of bleeding and treatment failure while patients receive acid suppression, and significant bleeding as opposed to 123 occult bleeding may be a better endpoint of acid therapy than pH (32). Testing the pH of aspirated gastric contents with paper or a pH meter also may not provide equivalent pH results. Several studies have noted clinically relevant biases between pH paper and pH meters in the pH range of 2 to 6 that would have led to overestimation of gastric pH in 4 of 51 patients (34) and would have resulted in inappropriate treatment for 28% of the samples tested in another study (18). These biases are believed to be related to the limitations of accurate pH paper assessment in the presence of salts (antacids) and interferences from bile, protein, and other substances found in an inhomogeneous sample such as gastric fluid (18, 56). Other studies have claimed that the magnitude of the pH bias is smaller than the error of pH paper measurement (typically read in 0. Clearly, pH testing of gastric aspirates has clinical utility in the determination of feeding tube placement, and pH paper can be used to judge the pH of gastric aspirates, provided that appropriate consideration is given to its limitations. Ar ch iv ed Is one brand of pH paper better than another brand in improving patient symptoms and time to treatment of chemical burns in emergency and urgent care patients, and in improving the accuracy of nasogastric tube placement in inpatient, endoscopy, home care, and nursing home patients There is insufficient evidence to recommend one brand of pH paper over another brand of pH paper for use in the treatment of chemical burns or placement of nasogastric tubes. Two studies were found that compared pH results between different brands of pH paper. Brands with multiple color changes were found to be more accurate when compared to pH meter results (57, 58). Products providing more than 1 color change or multiple overlapping scales of colors were found to detect more subtle pH changes and were preferred by nurses and anesthetists over those papers with a single color change. The accuracy of single-color pH papers ranged from 20% to 83%, depending on the paper (57). Single-color pH 124 papers were noted to have major deficiencies discriminating pH 4, whereas multiple-color papers had more difficulty in the low range of pH 1 (58). In light of the age of these studies (1983 and 1987) and variety of pH papers available on the market, there is insufficient evidence to recommend one brand of pH paper over another for monitoring antacid therapy, feeding tube placement, or irrigation of chemical burns. However, the use of pH testing in managing acid suppression therapy and determining the efficacy of wound irrigation after chemical exposure will require further studies that directly examine the effects of pH testing on patient outcome. More important, studies are needed to determine the type of monitoring that is most effective and to define when more accurate measurement by pH meter is required or when less precise estimates by pH paper may suffice. Clinicians are encouraged to thoroughly examine the accuracy, applicability, and benefits of any test before implementation in patient care and verify continued outcomes periodically after any change in practice.

Electric traction allows high acceleration from a standing start antibiotics for dogs canada purchase noroxin 400 mg without a prescription, which is useful when there is frequent starting and stopping antibiotics oral contraceptives effective noroxin 400mg. However medication for uti burning purchase 400 mg noroxin fast delivery, this advantage fades as starting and stopping are less frequent and high speed is desired antibiotic dosage noroxin 400 mg free shipping. A final advantage of electric vehicles is that because of their lower vibration, all systems (including the electric motors, the air conditioning system, all electronics, and the body) tend to have a longer service life than their thermal equivalents. The disadvantages of trolley buses are the expense of building and maintaining them, visually intrusive infrastructure, and service inflexibility (made necessary by the need to access power provided via costly and thus limited-extent fixed infrastructure such as overhead contact wires). Express or skip-stop services would be provided by vehicles with thermal engines that do not require access to overhead contact wires or another external energy source. The other way to overcome the service inflexibility of trolley buses is to utilize "dual mode" vehicles that have full service capabilities both on and off wire. Dual Mode (Dual Power) Thermal-Electric Drives Dual mode vehicles combine an electric trolley bus with an internal combustion engine. Dual mode vehicles therefore have the advantages of both trolleys and normal buses with internal combustion engines. In the first, one axle is driven by the electric motor, the other by the internal combustion engine/transmission (as in Seattle). The second dual mode configuration uses an internal combustion engine and a generator/alternator (in lieu of overhead contact wires) to provide electric power to the motor or motors that actually turn the wheels, thus avoiding the need for both an electric motor and a mechanical transmission. This type of vehicle can also operate as either a trolley bus or a diesel-electric vehicle. With this approach, the ride quality of the vehicle is significantly advanced because the all-electric drive eliminates the often harsh shift points associated with hydraulic-mechanical transmissions, but this type of vehicle tends to have lower fuel economy than other configurations. Having internally generated or externally provided (via trolley wires) electricity allows powering of multiple wheels in the same way as a light rail vehicle, an approach used for vehicles in Las Vegas; Nancy, France; and Boston (as shown in Photo 6-O) and currently in service in Lausanne, Switzerland. The use of hub motors means that the floor can be very low in the center of the vehicle, making for a very wide aisle, a 100% low floor, and the ability to have a door to the rear of the rear axle. One disadvantage is that these motors are very expensive, and the resulting system is heavy. Dual mode vehicles are attractive for transit operations because they can combine the performance and other environmental advantages of a trolley bus when they are needed with the freedom of movement of a conventional bus using an on-board prime mover. Whereas a conventional bus requires maintenance of a single thermal engine and a tried and true hydraulicmechanical transmission, dual mode vehicles require more maintenance effort and cost because they have more components. Hybrid Electric Drives with Energy Storage Hybrid drives combine a dual power vehicle. A hybrid vehicle with energy storage allows an engine with less horsepower to be used because the engine can be run at a much more constant load. Conversely, the engine can recharge the energy storage medium while cruising or coasting. Regeneration during braking also recharges the storage medium and reduces brake wear and tear. The air pollution (and fuel consumption) advantages stem from the more constant load on the engine. It is much easier to optimally tune an engine to reduce emissions (Photo Credit: Berkhof Jonckheere) Photo 6-Q. This is one of the special benefits of hybrid propulsion systems, even when diesel engines are part of the mix. Hybrid vehicles can use either of the two propulsion system configurations noted above under dual mode vehicles, but they may not need trolley wires. The third type of dual power configuration available for hybrids involves a thermal engine, a motor/generator, and a mechanical transmission, all mounted on one drive shaft. This approach, similar to the approach used by the Honda Insight and hybrid Honda Civic automobiles, is being tested in revenue service in Seattle as a replacement for its Breda dual mode vehicles. This third type of dual power configuration has the weight penalty of a transmission motor/generator or alternator and the stepped shifting of a hydraulic-mechanical transmission; however, it tends to have better fuel efficiency and acceleration than alternative configurations. Fuel cells utilize hydrogen and oxygen to directly produce electricity in the presence of a catalyst, without engines and generators/alternators of any kind. There are two basic fuel cell approaches for vehicles, one involving the use of hydrogen gas carried in high-pressure cylinders (up to 350 bar pressure), and another in which the hydrogen is chemically separated from a liquid hydrocarbon fuel, such as methanol, in a reformer onboard the bus. Water vapor is the only exhaust product from a vehicle using pure hydrogen as a fuel, an improvement over the imperfectly combusted hydrocarbons, nitrous oxides, carbon monoxide and carbon dioxide that make up the potent greenhouse gas 6-15 mix emitted by internal combustion engines. Fuel cell technology promises to be an environmental boon for the transit industry as well as the entire large-vehicle industry because it can run on hydrogen created from a variety of renewable sources.

Doctor Chen breezed through medical school, and like every beauti- the Rape of Emergency Medicine Page 158 ful woman her own age, had only one consuming outside desire, to marry someone as pretty as herself, which she did in her first year of medical school. The marriage went rather well until her husband brought home, without warning, his mother, father, and aunt, and announced according to custom, they would be living with the Chens from now on. Eileen prided herself now and then on being somewhat Chinese, but this was carrying the tradition thing way too far, and from then on the marriage turned sour. Daily battles ensued with Eileen becoming less and less Chinese, and her husband taking on more of the characteristics of the last emperor of the Chen dynasty in America. But a most fortunate thing happened to Eileen Chen in her fourth month of pregnancy with her daughter, Annie Thieu Yen Chen, fortunate for them, if not necessarily for him. Her ex was crushed one night when his convertible car tumbled into one of the Malibu canyons rolling over several times. Most of her medical professors felt Doctor Chen should have gone into surgery for she had quick and intelligent deft hands, and more importantly, she thought three dimensionally. Her visual-spatial conceptualizations made her quicker and more accurate than her contemporaries who went into surgery. The Rape of Emergency Medicine Page 159 Had Eileen Chen been a first-generation immigrant, she probably would have gone into surgery, but being third generation, opted instead for the less arduous radiology residency with fewer nights on call. In the field of radiology she found a niche, her mind perfectly adapted to reading films with a certain intuitive notion, and from the beginning she seemed to get more out of an x-ray film than many of her colleagues. Her daughter Annie was now four years old, and Eileen wanted her to spend less time with her increasingly-possessive in-laws, especially her mother-in-law, who was insisting Annie call her "mommie" instead of grandma. At the age of three, Annie also stubbornly refused to speak any Chinese, further complicating the family situation, and at four, refused to use chopsticks. They felt resonance imaging was for the younger crowd, perhaps even a bit of diagnostic overkill, and there was another reason. They had invested a lot of money in the alreadyoutdated General Electric image intensifiers, so they wanted to get as the Rape of Emergency Medicine Page 160 much use and billings out of them as they could. They also had two years to go on their seven-year depreciation schedule, and early retirement of the equipment would mean recapture taxes on their original investment, thus offering them a strong disincentive to retool at the present time. In the meantime, a mobile imaging van came to the hospital on Tuesdays, creating artificial tie-ins to the hospital admissions schedule. Ironically, after her internship in general surgery, Eileen Chen had taken a year off to work in emergency medicine, and after that year, definitely decided to become a radiologist. She summed up the once and forever present state of emergency medicine in Los Angeles with, "I got tired of taking their shit. Eileen had also seen many Monks and Walshes, and like many physicians who saw the charade called organized emergency medicine, she never acquired much respect for emergency physicians, especially the ones working for Pyramid, Inc. Steinerman also knew if he asked her out in front of others, she would perfunctorily say no. But there were always the techs, other physicians, or nurses around every time Steinerman went over to "clarify" something on an x-ray film. Actually, Steinerman might just as well have asked her out over the hospital public-paging system since hospital employees have their antennae up at all times, are usually quite accurate, love discovering in-house affairs, and knew exactly why Steinerman kept coming over to re-check his own readings of the wrist and ankle films of his patients, and then only when Doctor Chen was scheduled to read. The x-ray crew and the operating room nurses are the best sources of gossip, and x-ray had Steinerman spotted a mile away. Doctor Chen had the suspicion all Asian women have when asked out by Caucasian men, even the ladies who only go out with Caucasian men, since the Asian affliction of white males is well known to them, forcing all of the beautiful ones to get unlisted phone numbers along with a restraining order or two by the age of twenty-five. Steinerman had pretty much used up his approaches, so he decided, the Rape of Emergency Medicine Page 162 in one of his clever moments, to use a little bit of good old reverse psychology. She was not a low-maintenance woman from the beginning, but it was a wonderful time for them. Being more than just clinically sound, the chemistry between Steinerman and Eileen Chen was quite correct, it did lead to a covalent bonding which they both hoped would further recombinate a superior dynastic line, which in time it did. Sir William was also a phylogeny-recapitulates-ontogeny white-supremacist Englishman, a small-minded, bigoted little man who was anti-Semitic, anti-black, anti-liberal, and anti-a-lot-ofthings. He was a member of the former aristocracy who sent all their children to medical school, strongly believing only children of physicians should be allowed to attend medical school. He did not belong to the new world symphony of upward mobility and intellectualism for all, but to an old order whose function was to preserve.
