Advanced Life Support (ALS) or Advanced Cardiac Life Support (ACLS) is a treatment algorithm followed by healthcare professionals when a situation arises requiring cardiopulmonary resuscitation (CPR) in cases of cardiac arrest, arrhythmias, stroke, or other related medical problems like poisoning. Advanced Life Support consists of CPR administration using oxygen administration via a bag or mask and chest compressions (see CPR Certification), which are now recommended at a 30:2 ratio of compressions to ventilations for adults, children, and infants to produce higher coronary and cerebral perfusion pressures. The electrical activity of the heart is monitored and depending on the type of cardiac arrhythmia, defibrillation is applied, and medications such as adrenaline (epinephrine), amiodarone, or atropine are administered. Saline or colloids may also be given intravenously to increase the circulating fluid volume in the body. End tracheal intubation may also be necessary to secure the airway in some cases, see Online CPR Certification.

While performing CPR, members of the Advanced Life Support team consider eight forms of potentially reversible causes of cardiac arrest, also known as “4H4T” as seen on the CPR Cetification Classes. The “H’s” are hypoxia (low blood oxygen), hypovolemia (low blood volume), hyper/hypokalemia (high/low blood potassium), hypothermia (body temperature well below normal), followed by the “T’s” which include tension pneumothorax (tear in the lung leading to collapsed lung and distortion of major arteries), tamponade (fluid or blood in the pericardium compressing the heart), toxic and/or therapeutic chemicals or medications, or thromboembolism (blood clot in the heart or lungs). Early intervention, early access, early CPR, early defibrillation, and early advanced life support save lives. This team of medical professionals consists of physicians from all disciplines, anesthesiologists, emergency medical technicians, and others trained in ALS designated to respond in a cardiac emergency.

Pediatric Advanced Life Support (PALS) is very much like ALS only it is designed to aid the pediatric healthcare provider in recognizing and managing critically ill infants and children at risk for cardiopulmonary arrest. There are medical emergencies specific to this age group, and the focus is placed on early recognition of distress as related to a specific medical diagnosis. ALS and PALS training is provided to healthcare professionals that work with adults and children, including physicians, physician assistants, nurses, nurse practitioners, paramedics, and respiratory therapists, across the country by the American Heart Association. Just visit www.americanheart.org or www.heart.org for further discussion on new recommendations and all aspects of assessment and treatment of victims of respiratory and/or cardiac emergencies and stroke, including basic and advanced life support interventions.

The chillers evaporator is a heat exchanger that transfers heat from a process or air conditioning water circuit to the chillers cooler liquid refrigerant. Most air cooled chillers in the UK chiller hire market will be fitted with a shell and tube evaporator, a plate heat exchanger evaporator or a coil in tank evaporator. A shell and tube evaporator is used primarily on chilled water applications. When a chiller is fitted with this type of evaporator the chillers cool liquid refrigerant flows through tubes encased in a shell.

The process or air conditioning circuit water fills the shell flowing around the tubes. As heat is transferred from the water to the chillers refrigerant the gas boils inside the tubes and the resulting vapour is drawn into the chillers compressor.

Hot water will enter the shell at one end, chilled water leaving at the opposite end.
A Plate heat exchanger evaporator can be used for chilled water or fluid cooling applications. Stainless steel evaporators are especially suited in food and beverage applications such as batch cooling or potable water systems.

A coil in tank evaporator comprises a coil block, usually copper, with aluminium fins to provide an efficient heat transfer surface. The coil block is then submerged in a chilled water tank which acts as a thermal buffer for the refrigeration system. This type of coil is suited to hire chillers used on process cooling applications, typically reactor cooling systems in chemical cooling, petrochemical cooling & pharmaceutical cooling systems.

Air Cooled Chiller Condensers

The condenser is a major component of a water chiller. The condenser is a heat exchanger that rejects heat from the chillers refrigerant to air. Some chillers are water cooled. A Water cooled chiller gives up its heat into relatively cool water from a cooling tower, air-blast cooler or adiabatic cooler. A typical air cooled condenser fitted to an air cooled water chiller will use axial fans (propeller type) to draw outdoor air over a finned tube heat transfer surface (heat exchanger).

The temperature difference or “delta T” between the hot refrigerant gas that is flowing through the condenser and the cooler outdoor air induces heat transfer. The heat reduction of the chillers refrigerant vapour causes it to condense into liquid. The last part of the chiller condenser is called a sub-cooler. The chiller sub-cooler reduces the liquid gas temperature still further, under its condensing temperature. The air cooled chiller is best suited to chiller hire applications. Chiller hire projects require systems to be delivered and installed quickly with the minimum of fuss.

People’s’s sundry reasons for cycling range between recreation and relaxation to club riding and racing. There are several that use their cycles as their main method of getting in the town whether it’s to and from work or as their only source of transport.

Without regard for your cycle use, cycling jerseys have now become an obligatory part of each bicyclists clothing collection.

Bike jerseys are specially made to be simple to wear clothing for the higher part of the cyclists body and are made to allow the cycle rider the ideal body movement while keeping the skin and body at a good temperature. There are plenty of types of bike jerseys, the basic types are either with long or short sleeves. However the range of designs and fabrics is skyrocketing all the time. Retro cycling jerseys to novelty cycling jerseys, the selections are mind amazing. As well as the various various designs, cycle jerseys also come in countless different styles and fits. Some do up with zips, while others have none and are simply slid to over the head. Each bike rider has different preferences as to the fit, look and style of the bike jerseys. Some heated discusses have happened about which is the best fabric to use for bike jerseys. There are one or two colleges of belief about which is best. Some fans are adamant that only natural fibres like cotton, should be used so near to the body, while others disagree the specially designed manmade fibres do a better job of allowing the riders skin to respire. Both talks have merit, so it essentially does remain up to the individual bike rider to select that will work the best for them. The only real way to work out the solution for yourself is to try both and see which is most snug for you personally. It is probable that each person will have their own ideas about what will best suit them.

Cycling jerseys are now made for almost any body shape, and there are actually a lot of selections for both men, girls and children. The most difficult part will be deciding on only one of the selection of cycling jerseys available in the shops today. Shopping online for biking jerseys is a way to save a little time and see the various choices that are typically available. Considering the growing trend toward riding bikes, the expenses and range of jerseys available is perhaps going to keep on increasing.

John Black writes about many subjects, as a cycling fan he adores his collection of cycling apparel which includes many retro cycling jerseys and cycling skinsuits.

Canon are a one of the big guns in the photographic world and have been for a very long time. The Powershot range is perhaps the most successful of their well known ranges of point and shoot cameras. Motion detection technology is now incorporated in the A590IS model, to set the best overall settings for any movement of the subject.

All small cameras suffer from redeye to some extent Red eye occurs because the flash is too close to the lens axis on small cameras. Redeye is removed from flash photos wiith the Canon face detection technology. That happens before they’re written to the memory card. It’s a great feature to anyone who takes a lot of flash pictures of friends and family.

Face detection also includes ’select and track’ which lets you pick one face from a crowd and concentrate on that face, even if the person moves around. For anyone with young children that’s an absolute boon! Exposure and flash are set to keep faces looking natural and with the optical image stablization system camera shake could become a thing of the past. You’re not limited to just a couple of focus modes though. There are plenty of choices for every shooting situation.

There are 3 settings for the image stabilization, which offers great image quality. Even if you try to take a blurry shot, you probably can’t! That’s how good it is. Remember that there is a 4x zoom so the image stablisation system is great for helping you make the most of that zoom range. Handheld long shots will be sharper and clearer because of the IS part of the A590IS.

Unlike the expensive and extremely highly specified Powershot G10, the A590IS is a powershot for the whole family.

Featuring 8 megapixels and a 2.5 inch LCD screen, the Canon A590IS is easy to use even for beginners, especially when it comes to printing. The A590IS features a dedicated Print/Share button for direct printing and downloading. It’s literally pushbutton simple, so even your children can do it. If you’re looking for a small, easy to use camera at a great price it’s hard to beat the Canon Powershot A590IS.

How To Solve The Problem Of Wet Packs in Steam Autoclaves and Sterilizers.

As a manufacturer of steam autoclaves, we at Medi-Clave frequently hear feedback from current and prospective customers alike, regarding condensate issues (wet loads) in their chamber, post-sterilization, impeding satisfactory processing results. In fact, it could very well be the single leading technical issue we have run into over the past 15+ years of manufacturing sterilizers! To understand why, you really have to understand the myriad of potential causes, to appreciate the complexity of solving this simple problem.

When helping our clients identify the source of the issue, we begin by evaluation of the most common suspects first. Foremost among those suspects is the steam supply. Frequently we find that steam quality is the culprit in leading to excessive condensate formation within the autoclave. Our first recommendation to clients is to determine if you are placing excessive demand on the boiler. Next, examine the steam circuit/supply and look for potential areas of condensate formation such as dead legs or improperly trapped or insulated piping. The duty of a steam trap is to discharge condensate while not allowing the escape of live steam. The further away the steam line is from the heating source/medium, the more likely condensate is to form, and require removal from the system. One should consider proper insulation for piping,the further away the steam line is, the more the need for insulation. Lastly, have your sterilizer service people check the jacket steam trap and check valve at the drain port to be sure they are clear and functioning properly.

If you or your staff have no experience with proper steam supply design/piping, we would recommend that you contact Autoclave experts or Steam Sterilizer expertsfor an evaluation.

If the water content of the steam is 5% by mass, then the steam is said to be 95% dry and has a dryness fraction of 0.95.satisfactory dryness fraction is .97) Once you have established that the steam supply is not the source (of excess condensate), it is time to look more closely at what is being loaded into the vessel, the design of the sterilizer itself and perhaps the operation of the autoclave.

Another common cause of wet loads is the load itself. However tempting it may be to pack the chamber full of product, in order to keep up with demand, (dense packing) is frequently a cause of excessive condensation which cannot then be completely flashed off by subsequent steam injections. Large quantities of hard goods or even complex packaging can make proper steam circulation a challenge.  

Steam enters the chamber and contacts the product, it is essential that the steam collapse (condense) on the product in-order for the heat to be released to the load. But ultimately the water formation must be discharged through condensate management or re- vaporized in order to prevent contamination of the product. Removal of the excess water is crucial to prevention of insulating the load from the steam. That said, too much steam, at too fast a rate can result in excessive water formation which might overwhelm or swamp steam traps. Be sure that your steam traps are properly sized.

To dry the load after the fact, many users are tempted to employ excessively long deep vacuums at the end of the cycle. Because the chamber is heated (via the jacket) and the fact that water will flash off into steam at a lower temperature under vacuum, this is relatively successful. But what ultimately results is an unnecessarily long cycle time, and potentially a non-sterile load as water can collect in areas, and insulate the intended product from achieving temperature. Deep long post-sterilization vacuum drying phases are like closing the barn door after the horses have escaped.

When we are asked to assist under these conditions, we typically look to prevent (or greatly reduce) the formation of condensate by making sure that the load itself is brought up to a certain temperature prior to the introduction of steam. One simple way this can be accomplished is by defining a proper pre conditioning phase at the beginning of the cycle.

In Summary: Check the quality of your Facility Steam, including possible excessive demands on your boiler.
Check piping insulation from your steam source, to the autoclave. Check the way you pack your loads and do not over pack the chamber! Check the size and operation of the steam-traps and the drain globe valves leaking through. Check for clogged drains pipes and drain ports. Check your vacuum drying phase program settings and operation. Check or add a controlled pre-conditioning phase at the beginning of the cycle.

As an alternative you might wish to consider simply increasing the jacket temperature set-point, as long as it does not interfere with maintaining the temperature uniformity within the chamber during the sterilize dwell phase. A word of caution, merely increasing the jacket temperature could result in the super-heating of the steam, in the case that your condensate issue is not particularly bad, so use this strategy cautiously.

There are some unique approaches that can be causes, or solutions, to the condensate formation issue.

These include: Charge Rate Control (CRC). Many autoclaves are not equipped with a proportional control valve, or the necessary control system capability, to control the ramp up or charge rate of steam injection during the cycle. If a chamber does not have some means of valve configuration, or software limitations to control the rate that steam is added to the chamber, the result could be a flooding of the chamber with steam that results in instant condensate formation (this is a common problem found in South African Hospitals and can be effectively rectified  by adapting to the right approach) . If the steam injection were to be ramped up more slowly, the amount of steam and subsequent condensate can be more easily controlled.

There are many causes for condensate formation, in fact, condensing of steam is essential in heat transfer and hence sterilization, but too much condensate is detrimental. If you are experiencing such problems, try some of the above in identifying the cause, or contact Medi-Clave for assistance.

It is all too simple for an accidental spark to start a blaze. And, as the state has recently seen, weather can collaborate to prolong and expand the breadth of the flames. However , employing fire-resistant foam offers some shield against smaller blazes, and as simple as spraying in insulation.

Froth insulation spray offers another method of insulating a building. It is inexpensive in the energy output it saves you. It’s also greener than other insulating materials and flame resistant. Foam is effective as a sealant because it expands to fill every crevice and empty space, even between rafters and joints. In this manner, the insulator keeps out air and waste, among other stuff.

As part of a fire protection system, its sealing feature is also of huge advantage. With the foam, you don’t have to stress about air pockets in the material where combustibles can collect or cause other hazardous Problems. You also do not need to fear flames getting into unfilled pockets to either burn the structure beneath or become hotbeds should a fire happen. In addition, the undeniable fact that the insulation keeps air out stops more air from reaching a blaze or causing deadly backdrafts.

One of the best features about fire resistant insulation is that the material itself doesn’t burn. Even if fire somehow gets into the insulation, the substance doesn’t catch fire. Admittedly, after extended exposure to flames, the surface shows burning, but the flames never take hold. Considering the cost of rampant fire damage, charring is a much better and more reasonable trade off.

In trial tests, investigators built three sample crawl spaces. This trial was conducted to compare the performances of one kind of insulator to an untreated’calibration’ construction. This first was employed for a calibration test. The other 2 were treated with one sort of a spray in insulation product. Each crawl space was tested to a’failure time’ in which the flames consumed the plywood or couldn’t be sustained.

The calibration deck exhibited steady flames from the front after 6 mins of exposure to a flame source placed within the construct. After 9:30 minutes, the blaze penetrated the plywood.

The second and 3rd tests reflected similar results, which surpassed the outcome of commercial standard tests. Particularly, after 1:40 minutes, the controlled blaze ate into the insulation surface, but there was no ignition. After 3:40, there was sporadic ignition of the foam’s surface. Ignition ceased after 8:30 minutes. In almost 10 minutes of exposure, there was no burn through of the test material nor the plywood above it.

The investigators permitted the flame source to burn until it collapsed, a period of nearly 20 minutes. The test was finally ended after twenty-six minutes. There had been burning over the whole of the insulating surface, and some loss of material where the flames touched the surface, but the plywood was completely intact as was the majority of the spray in material.

Other products don’t last nearly as long in tests. Clearly, fire resistant insulation is an effective way to protect your building. The advantages are clear from the tests. Choosing a green, simple to install and flame resistant product would be of great benefit. With the properties of froth insulation spray, you can install it in a new or existing building. Foam systems for fire protection are a smart and efficient choice for any structure.

There are not many things that are more restful on a warm, summertime’s evening than preparing for yourself a large glass of lemonade, trekking out to the garden, and setting yourself down in your luxury sauna or spa.

And if you don’t like to read, many of the newer spa models have come out with high tech accessories like 17 inch LCD flat screen televisions, DVD players, and upscale stereo sound systems. You can also find more and more saunas with luxury resort like amenities such as towel warmers, underwater lights, and even seat warmers.

A lot of people, who want to be more social, see the sauna as a place to invite their friends and neighbors. What better excuse is there to get someone to come over to your place than an invitation to enjoy time in your hot tub. Who’s going to turn that down?

Saunas come in a variety of style, sizes, and shapes - so you should have no problem finding the perfect one for yourself. If you give a lot of parties, you can find many spas that very easily seat up to eight people. On the other hand, If you prefer smaller more intimate gatherings, you can opt for one of the smaller 4 unit models.

There used to be a time when having a spa was the sign of affluence and wealth. Nowadays, however, the hot tub prices have come down so much that even the average homeowner can afford them. And its never been more true than today - making now one of the best times to purchase a spa. With the current state of the economy, spa dealers are making deals with potential customers as soon as they walk into the door.

The recent natural disasters along the U.S. gulf coast reminds us of an important factor in purchasing sports cars-the need to avoid purchasing a flood-damaged vehicle.

A sports car that has been flooded is likely to experience numerous difficulties that will shorten its lifespan.

Among the risks is the greater likelihood of significant rust problems. A previously soaked interior lends itself to rusting out floorboards and other often hidden spots.

More importantly, however, are the very real mechanical problems that can come about due to the flooding of a sports car. If water levels reached a high enough point, it is possible that grit, grime and water entered the engine and exhaust system. The residue can significantly impair performance and can shorten the car’s effective life considerably.

Flooded sports cars also frequently suffer from electrical problems. A soaked electrical system lends itself to corrosion and an increased risk of short circuits. Repairs will be necessary, and electrical work can bring with it considerable expense.

Fortunately, it is possible to avoid purchasing a sports car that has been flooded. There are a few things you can easily due to mitigate the risk of acquiring a previously flooded car.

First, perform an automobile history check through a service such as CarFax. Although not foolproof, this kind of check can tell you if any flood-related insurance claims were made with respect to the vehicle and may provide you with other information hinting at water-related problems.

Secondly, beware of too much new car smell. A soggy car is likely to start producing interior mold and an unscrupulous seller may attempt to hide this telltale sign of flood damage by utilizing strong deodorants. An unaware buyer may purchase the car and not smell the hint of flood damage until some time after the purchase is made. If a car smells “too good” or seems to be over-deodorized, make sure to take extra time to investigate possible flooding.

Finally, advise your mechanic to look for signs of water damage. Any time you buy a sports car, particularly a used model, you should have your mechanic evaluate the vehicle. If you have reason to be concerned about potential flood history, remind your mechanic to be on the lookout for any water damage indicators.

The great devastation wrought by floods has been known to bring out the best in people willing to help those adversely affected. Unfortunately, history also indicates there will be people willing to profit on sports cars impacted by storms without offering full disclosure of past water damage. Do not allow yourself to be victimized by the seller of a once-flooded car, take steps to protect yourself from these unscrupulous sellers.
