Courtesy of ACLS-Algotithms.com (Click image to view site)Editor’s Note:It’s funny how you can go an entire career doing something (CPB) and hear the same thing every day, but actually not evaluate what it means. Yes, I have taken ACLS and studied the electrophysiology of the heart.So anyway, we have just taken off the X-Clamp, and the patient is relatively warm, and we decide to cardiovert due to fibrillation. Pretty standard procedure- we see it more often than not. At this point the cv surgeon tells the nurse to go with an asynchronous as opposed to synchronous shock mode. I had a brief moment of clarity… for the first time in 3000+ hearts, I actually think to myself, disassemble the two words “synchronous” and “asynchronous” and realize I really didn’t understand the difference, or what physiologic conditions dictated which mode to use.I feel foolish in revealing this personal information gap or cluelessness, but I figure there might be a few others out there that may not truly understand this difference. So bear with me (those perfusion savants out there) and I’ll just go ahead and put down some Cardioversion 101 info here 🙂 Synchronized cardioversion is a LOW ENERGY SHOCK that uses a sensor to deliver electricity that is synchronized with the peak of the QRS complex (the highest point of the R-wave). When the “sync” option is engaged on a defibrillator and the shock button pushed, there will be a delay in the shock. During this delay, the machine reads and synchronizes with the patients ECG rhythm. This occurs so that the shock can be delivered with or just after the peak of the R-wave in the patients QRS complex.Synchronization avoids the delivery of a LOW ENERGY shock during cardiac repolarization (t-wave). If the shock occurs on the t-wave (during repolarization), there is a high likelihood that the shock can precipitate VF (Ventricular Fibrillation).The most common indications for synchronized cardioversion are unstable atrial fibrillation, atrial flutter, atrial tachycardia, and supraventricular tachycardias. If medications fail in the stable patient with the before mentioned arrhythmias, synchronized cardioversion will most likely be indicated.=Unsynchronized cardioversion (defibrillation) is a HIGH ENERGY shock which is delivered as soon as the shock button is pushed on a defibrillator. This means that the shock may fall randomly anywhere within the cardiac cycle (QRS complex). Unsynchronized cardioversion (defibrillation) is used when there is no coordinated intrinsic electrical activity in

Solves gravity flow problems where the pipe is only partially full and is under the influence of an elevation head only.v = (1/n) R0.667 J0.5where,v = velocity, m/sn = Manning CoefficientR = Hydraulic mean radius, mJ = Hydraulic gradient, m/mManning Coefficient, n for ADPF fiber glass pipe is taken as 0.01Darcy-Weisbach Equation: It states that pressure drop is proportional to the square of the velocity and the length of the pipe. This equation is valid for all fluids in both laminar and turbulent flow. The disadvantage is that the Darcy-Weisbach friction factor is a variable.J = ( f.L.v2)/2.g.Dwhere,J = Head loss, mg = Gravity constant, 9.81 m/s2v = Velocity, m/sD = Inside diameter, mf = Friction factorL = Length of the pipe, mThe well known Reynolds number equation is used to characterize the fluid flow.If the flow is Laminar,f = 64 / ReIf the flow is Turbulent, the friction factor can be determined from the Moody diagram found in most fluid mechanics texts or calculated from the Colebrook equation. Pressure drop in fittings: Head Loss in Fittings is frequently expressed as the equivalent length of pipe that is added to the straight run of pipe as shown below. This approach is used most often with the Hazen-Williams orManning equations.

Under certain conditions, these shock forces can reach magnitude sufficient to rupture or collapse a piping system, regardless of the material of construction. The transient pressure is the rapidly moving wave which increases and decreases the pressure in the system depending on the source of the transient and direction of wave travel. Rapid valve closure can result in the build-up of shock waves due to the conversion of kinetic energy of the moving fluid to potential energy which must be accommodated. These pressure waves will travel throughout the piping system and can cause damage far away from the wave source.. Download Shock Wave for Firefox. הורדת Wave Shock עבור Firefox.

Interested in Cleaning? Get Cleaning articles, news and videos right in your inbox! Sign up now. Cleaning + Get Alerts General Pipe Cleaners’ Kinetic Water Ram uses a burst of compressed air that drives a shock wave (kinetic energy) through water to break up the stoppage. The shock wave bypasses vents and stacks to break up clogged drains. You get instant impact with no pressure buildup. The built-in pump and pressure gauge lets you choose the right amount of force for each job. Thanks to technical advancements, the device is designed to deliver effective results without risking damage to the plumbing system. To some, this might sound too easy and create the belief that the shock wave will damage pipes or cause a bigger issue. Well, that isn’t the case, and here we will discuss the top myths of the Kinetic Water Ram and how to properly use the product.Myth #1 – “This will damage the pipe.”The Kinetic Water Ram does not pressurize the pipe, so the thought that it will burst the pipe due to the introduction of psi, is not correct. The Kinetic Water Ram creates a shock action that travels through the pipe like a wave and goes around tight bends, and quickly and effectively clears the obstruction and flushes water particles away. This method is efficient and reduces the risk of harming pipes.Myth #2 – “I’m going to get wet every time.”Now, while you could get wet the first time you use it, you shouldn’t get wet every time you use the Kinetic Water Ram. We recommend pumping the machine up to 10 pounds, and if that doesn’t work, move up in 5-pound increments until the stoppage is clear. You will want to start slowly and gradually work your way up in pressure as necessary. You also need to hold the Kinetic Water Ram down with as much force as you’re discharging. If you don’t do this crucial step, then the pressurized water stream will blow away from the pipe and you’ll get soaked. If you start with too high of a pressure, then you will.

In each world (excluding Hideout Helm) and Kong Isle, each one holding a blueprint colored after a Kong's main color. The color of their hair tells which Kong's blueprint they hold. Their main attacks are creating shockwaves and using various punches. While they are resilient to most attacks, Kasplats are easily defeated by the shock wave attack or a musical instrument. There are a total of 40 Kasplats in the game.KlumpKlumps are large Kremlings who mainly attack by throwing green oranges. At close range, they can also push back the Kongs with their bellies. Although the Kongs can attack them directly, Klumps can only truly be defeated by oranges, the shock wave attack, and a musical instrument. Likewise, Chunky Kong can defeat Klumps by touching them while in his Hunky Chunky state. Klumps drop three oranges when defeated.KlobberKlobbers are green Kremlings hiding in barrels. If a Kong gets close enough, they will pop their heads and feet out and follow the Kong in an attempt to hit them. Klobbers can't be harmed with direct attacks at all; the Kongs will hurt themselves if they even touch a Klobber directly. Klobbers can only be defeated with oranges, the shock wave attack, or a Kong's musical instrument.TNT BomberTNT Bombers are red Klobbers hiding in TNT Barrels. Like Klobbers, they follow the Kongs when they get too close, but if they don't catch them, they will explode shortly after. They can't be attacked with normal direct attacks, but they are easily defeated by

Shock-wave Synonyms: 3 Synonyms and Antonyms for Shock-wave

Different components of your plumbing and pumping systems. That’s why it’s important to get rid of water hammer as soon as possible. A loose pipe or worn stop value could end up costing you thousands of pounds.Secure Any Loose PipesIf loose pipes are turning mild shock waves into loud bangs, you can prevent it by securing pipe straps, adding new pipe straps or tightening studs or joists.Remember, do not mix different metals when securing pipes. A steel strap should not be used to secure a copper pipe or vice versa. Different metals can chemically react and cause corrosion of the metal.If the problem pipes are located in hidden areas, then you will more than likely need a plumber to come out and help you find the issue.Wrap Pipes in Foam InsulationAnother idea is to wrap pipes in foam insulation. The foam should help prevent banging by absorbing the shock waves. This can also help prevent pipes from freezing in the winter. Make sure to leave space for expansion around the pipe.Fix Washing Machines or DishwashersIf the banging only occurs when using the washing machine or dishwasher, then the problem is likely the solenoid valve. The solenoid valve is a component of your machine used to shut off the water supply. If the response time of the solenoid valve is too quick, then the fluid inside the valve is abruptly stopped. In this case, the fluid reflects like a wave causing a shock wave back up the pipe that you hear as a bang. The simple fix is to choose a solenoid valve or other valve type that has a slower response time.Install a Water-Pressure RegulatorA common cause of water hammer is high water pressure. If your pressure is running near 100 psi, then it’s likely the cause of your issue.. Download Shock Wave for Firefox.

Shock Waves and Blast Waves - SpringerLink

Have a water supply that is controlled by solenoid valves. These are electrically operated and they stop the flow of water immediately. When this happens, the water reflects back up the pipe and creates a shock wave that causes the bang.Worn Stop ValvesThe hammering may also be caused by worn stop valves. Stop valves can cause water hammer if they have loose gland packing and/or worn washers. The valves will generally be open when the water hammer shock wave travels through the pipework and the shockwave could well 'rattle' the valve handle and a loose jumper.Clogged Air ChambersIf you’ve never had water hammer and one day you suddenly experience it out of the blue, then it’s likely your water system’s air chambers are blocked. These chambers often become blocked with water or residue from minerals found in water. The blockage will stop the chamber from absorbing the pressure in your system and, as a result, you will hear an occasional bang.Water Ripples from the TankAnother cause of hammering pipes is water ripples created by a float valve inside your water tank. When water flows into the tank, the valve float rocks up and down, constantly closing and opening the valve. This creates a “wave system” that echoes along the pipes, causing the hammering sound. Plastic water tanks can flex considerably, so they should have a reinforcing plate (metal) to stop them moving.Fast-acting valvesA common cause of water hammer can be fast-acting valves on appliances such as washing machines or dishwashers. These valves suddenly stop the water that is moving along the pipes. A shockwave results and this causes the pipes to shudder, causing the banging. The banging gets worse as the valves are worn.How to Stop Water HammerWater hammer isn’t just irritating - it can also go on to damage
