Technology in Practice Part II: Intra-Aortic Balloon Pump Background of Technology Before tThe intra-aortic balloon pump (IABP) became a successful piece of technology‚ it was first introduced by Harken in 1958 in hopes of treating left heart failure (IABPumpers‚ 2006). Harken thought that by removing a certain amount of blood from both femoral arteries during systole‚ and rapidly replacing it during diastole‚ he could augment the cardiac output and increase coronary perfusion. However

GAS LAWS Properties of Gases Gases expand into any available volume • gas molecules escape from open containers. Gases are completely miscible • once mixed they will not spontaneously separate. Gases are described in terms of T‚ P‚ V and n Volume‚ Amount and Temperature • A gas expands uniformly to fill the container in which it is placed – The volume of the container is the volume of the gas – Volume may be in liters‚ mL‚ or cm3 • The temperature of a gas must be indicated

Describe the respiratory system role with oxygen and carbon dioxide. The respiratory system is responsible for the movement of gases involved in cellular metabolism. b. Why is oxygen needed? Oxygen is needed because it is used up during the aerobic breakdown of glucose. c. What generates CO2? Carbon dioxide arises from the aerobic

Gas analysis techniques Terms for gas analysis techniques Concentration The term concentration describes the amount of a substance‚ expressed as mass‚ volume‚ or number of particles in a unit volume of a solid‚ liquid‚ or gaseous substance e.g. alcohol in beer or oxygen in air. Different units are in use to describe concentration in gases: Mass concentration Concentration expressed in terms of mass of substance per unit volume [g substance/m3 gas volume] ¢ Volume concentration Concentration

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

IMPORTANCE OF SELECTION The best selected pump for any duty condition may be most Hydraulically fit or with best efficiency but it may not be most suitable or cost efficient. The selection criteria must include maintainability and reliability as a foremost factors.Engineers overlook systems where the pump has to be used and lack of experience often results in under performing and oversized or wrong pumps with higher operating costs .Considering pump as a plug and play device will always add cost
