Scientists have been trying to create artificial blood since 1883 (Indian J Crit Care Med. 2008 Jul-Sep). Using real blood for medical causes has it’s problems, the blood used must be compatible with the patient, if it is not, it can cause sickness to the patient and their condition may escalate. This is just one of the many complications with using real blood. Red Blood Cells, White Blood Cells, Plasma and Platelets are the main products extracted from donated blood, each of these products are used for something different and need to be included when artificial blood is created.
Technologies centred around artificial blood include an Arterial Blood Gas Analyser and a Pulse Oximeter, these technologies allow measurements of oxygen saturation and carbon dioxide concentrations in blood which helps evaluate the ventilation, oxygenation, acid-base levels and oxygen-carrying capacity of the blood. The development of artificial blood can eradicate any problems with blood transfusions in the future as an inexpensive and risk free alternative.
An Arterial Blood Gas Analysis (ABGA) measures the oxygen saturation and carbon dioxide concentrations in blood, which indicates, how efficiently the lungs are distributing the carbon dioxide and oxygen to and from blood. (Medical Dictionary. 2003). It is an invasive machine that takes a small sample of blood from an artery and measures the oxygen levels using two electrodes; these electrodes produce an electric current after the oxygen has flown between them and through a membrane. The current produced is proportional to the volume of oxygen in the blood. However it is the pH levels of blood that measures the carbon dioxide concentrations.
Knowing the blood’s pH levels, oxygen saturation and car...

...herefore needs to be free of pathogens before it can be used. Finally, it must be compatible with the patient otherwise other illnesses may occur. Without research scientists wouldn’t have been able to look into donated blood and therefore they wouldn’t have began to develop artificial blood, making a doctors job much more difficult than it can be with this alternative way of transfusing blood.
This report is proven to be reliable as I used many different sources from the internet, to text books, to HSC online. Before I used my information I made sure that the facts given were relatively the same on different sites. If the information was different I did not use it, and looked for stronger confirmation to back up my statements. In text references were used to show where I got certain material from, therefore giving further evidence that this information is reliable.

Essay about Arterial Blood Gas

- Arterial Blood Gas Indications: An ABG is ordered as a way to assess or manage a patient’s respiratory and metabolic acid/base balance. The test assesses the pH of a patient’s blood and is used as an indicator for the particular cause of the acidosis or alkalosis. An ABG is also used to measure adequacy of treatment for an acid/base balance. An ABG can also be used in the measurement of adequacy of oxygenation. Type of Test and testing procedure: An ABG is usually acquired through withdrawal of arterial blood....   [tags: Papers]

Description Of An Artery : Arterial Pulsation Essay

- Hitting an artery: Arterial pulsation will be felt when palpating the vessel therefore this should not happen. Bright red blood will propel out under force if an artery is penetrated. In this circumstance you should release the tourniquet, take out the needle and apply pressure for five minutes to ensure the stoppage of blood flow (haemostasis). Make sure the site has stopped bleeding prior to the patient leaving. Recommend that they return to the surgery in order to make sure they are fine and checked - a physician should always check the patient before being released....   [tags: Blood, Artery, Vein, Hematology]

Essay on Blood Types Of Blood Type

- The universal blood type is blood that not containing A, B, and Rh antigens, this type of blood is known as type O negative. Individual with this kind of blood are considered an important blood donor because their blood can be donated to people of any blood type (Science 0nline, 2009). Blood types are an important achievement of Karl Landsteiner’s research on blood. This research determines that there are three types of blood and its characteristics. The type A and B carry a specific and different protein or antigen while the third type does not contain either antigen....   [tags: Blood, Blood type, Red blood cell, Immune system]

A Short Note On The Tension Between Alveolar Gas And The Gas Essay

- The lungs, with many alveoli of various sizes are inherently unstable. Surface tension in the lungs between the alveolar gas and the fluid lining the alveoli plays an important role here. Alveolar instability due to surface tension is produced as described below: When two alveoli with different radius connect with each other, the amount of pressure generated (P) in each is, P= (2 × surface tension)/radius. Therefore, when the surface tension is constant, the pressure in the smaller alveolus will be more than the larger alveolus, which makes the lungs unstable....   [tags: Carbon dioxide, Oxygen, Blood, Red blood cell]

Essay on Blood: Questions and Answers

- 1. What is the function of the blood. What specific materials does it transport. Why are these substances important. Be specific – explain why these substances contribute to homeostasis. Blood is composed of plasma (clear extracellular fluid) and cellular components, which consist of red blood cells, white blood cells, and platelets. Necessary body fluids, nutrients, gases, chemicals, and wastes are transported throughout the body by the blood. The functions of the blood include respiration, waste elimination, thermoregulation, nutrient delivery, immunity and defense, hormone delivery, and water and pH balance....   [tags: Blood]

Heating Exchange For Gas Exchange Essay

- Opercular pumping is a mechanism utilized by certain fish for gas exchange. An opercular pump is used to pump water through the gills in an almost continuous unidirectional flow (SHSU). A dual pump is used in tandem in order to drive the unidirectional flow, both a buccal cavity and opercular cavity work simultaneously. The oral valve along the buccal cavity opens, allowing an influx of water. This influx of water causes an expansion of the opercular cavity, dropping the pressure (Hall). Water then enters into the opercular cavity and flows out due to opercular cavity compression....   [tags: Blood, Oxygen, Viscosity, Turbulence]
