Oxygen is vital to system and organ function in our bodies. In order to be carried around the body, molecules of oxygen attach to the haemoglobin proteins in red blood cells. The amount of oxygen (measured as a %) in haemoglobin proteins is called ‘oxygen saturation’ and this percentage can be determined using pulse oximetry. The values from pulse oximetry are useful as they tell us how much oxygen is actually reaching the different organs and systems in the body. Pulse oximetry uses devices called pulse oximeters that attach to an area on the patient where blood flow can be measured (most commonly on the finger). Light is then shone through the skin it is positioned on and a detector on the other side measures the amount of light that makes it through. The amount of absorbed light is indicative of the oxygen concentration and as such, a pulse oximeter does not directly measure oxygen saturation but rather closely estimates it. Normal levels of oxygen saturation are between 95-100%...

A spirometer is a device that is used to test lung function by measuring air inhalation and exhalation. This kind of testing is invaluable in, among other things, disease screening, health examinations, and epidemiological investigation. The three most common tests in spirometry (mentioned above) are the FVC test, the VC test, and the MVV test. Looking first at FVC, this test focuses on forced exhalation and inhalation and measures the changes in the volume and flow of breath under these conditions. This is one of the most important measures in distinguishing between conditions of the lungs. VC testing then measures these changes in a relaxed state i.e. the subject need not force either inhalation or exhalation, but rather try and breathe normally. The aim of this testing is to reflect the potential capacity of the respiratory function. Lastly, MVV testing is a load test that measures the amount of ventilation obtained by repeating maximum voluntary effor...

An electrocardiogram (ECG) is a medical tool that is used by doctors to assess the electrical as well as the muscular functions of the heart. Your heart is a two stage electrical pump; an ECG uses electrodes placed on your body to measure the electrical activity in your heart. An ECG test can provide you with useful information about your heart rate and rhythm, and it can help your stay informed about whether you are at risk for heart disease, hypertension or a heart attack. While taking an ECG test is quite simple, the interpretation of the results require a qualified professional with significant training – D-Heart is the first ever ECG device to provide all the relative features, all in one simple, reliable and portable package. D-Heart is a smartphone ECG device that allows just about anyone to perform an ECG from the comfort of their own home. This can free up the doctors time and allow him to track vulnerable patients who are not admitted and to intervene if needed....

Well, the clue is in the name. These machines suck in normal air – which has roughly 80 % nitrogen and 20% oxygen and force it through a special sieve. They are used on patients who have poor lung function as the higher concentration of oxygen allows the patient to get sufficient oxygen. So, how exactly does an oxygen concentrator work? The oxygen concentrator’s sieves trap the nitrogen and pump out oxygen at concentrations of up to 95%. The purity of the oxygen depends on the size of the sieves and the power of the motor. From there the sieves hold onto the nitrogen until they are saturated. Most machines have a 6000-8000 hour life span. After this time, the sieves need to be replaced. Oxygen concentrators are not only convenient, but they are also affordable and do not need to be refilled on a regular basis. These factors make this medical device a commonly used item for oxygen therapy at home as well as on patients in hospital. SA Healthcare is one o...
