imagine what would happen if you closed your nostrils for a minute? or what would happen if you go sea diving without having an oxygen tank that is properly concentrated? ofcouse suffocation . oxygen is highly needed for the respiratory system of the body. in surgeries oxygen tanks or concentrators are used to supply the correct amount of oxygen to the patient and oxygen analysers are devices used to measure and calibrate the right amount of oxygen coming out of a concentrator or tank.consequently determining also the conditions of the concentrator. however most of these devices are too expensive to be purchased in developing countries. the big question now would be, do these developing countries perform any surgeries in their hospitals”? a very big yes! then how do they determine the concentration going to the patient? well that is a very good question to start a research on.

healthy is one of the main priorities of a policies but not all countries live to its standard.healthy issues are compromised due to a number of factors and it is the lack of necessary resources in most developing countries that leads to negligence of safety.talking about concentrators in malawi, research shows a lot of these medical devices being used are just a donation from charitable organisation and most of these donations do not come as new equipment hence their litle efficiencies. with this in mind, it is evident that the output from these concentrators cannot be accurate. however one cannot be able to tell the inaccuracy of the devise unless they measure its performance. then how can this performance be measured?

the performance is easily measured by measuring the concentration of the oxygen being using the oxygen analyser. but is this the same way the performance is measured in developing countries? most hospitals in lack these measuring tools due to their high price and perfomance is measured by testing on patients. if the patient is able to survive after the concentrators then well the performance is just okay else if they die then suspicion to the performance begin to arise.

this summer we will be addressing this problem by coming up with a device that shall measure oxygen concentration from a concentrator and tanks to be used in low resource hospitals. the device shall be ten times cheaper compared to the current analysers on the market, giving room for developing countries to purchase.
