Interpret acid-base results on your iPhone

During my medical school years and now when I myself practice medicine, I have noticed that a lot of people have trouble interpreting the arterial blood gases (ABG) test. This test normally provides partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), pH and bicarbonate (HCO3) values. It is important and quite easy to notice if some of these figures are not normal, but interpretation is crucial and sometimes difficult. For these reasons I am sure a lot of practicing medical workers will be pleased to hear that there is now a great application for the iPhone which can be of big help during the interpretation of the ABG test.

The mentioned app is called Acid Plus and is available through the iTunes Store for only $1.99. Acid Plus is extremely easy to use. You open it, enter the ABG test values and the app interprets it for you. Take a look at some of the screen shots.

If you turn the iPhone to landscape view, you will see a colorful graph with an arrow pointing to the disorder.

Acid Plus will also provide you with common causes of the primary acid-base disorders.

Acid Plus rapidly found its way into my top most useful medical apps for the iPhone. If you are practicing medicine and own an iPhone, you need to have it.

Lab in your cellphone

There are many healthcare problems in the developing countries, like lack of medical staff and equipment, and this is why I helped start the openECGproject. Now, a great concept to try an fix these problems is to utilize devices that are already present and hack them to be useful for patients. Devices like cellphones are a perfect example. And, this is exactly what the research team led by Dr. Aydogan Ozcan from the University of California, Los Angeles (UCLA) has done. They have developed an innovative lens-free technique for rapidly and accurately counting targeted cell types in a homogenous cell solution. Their vision is that individuals would one day be able to draw a blood sample into a chip the size of a U.S. quarter, which could then be inserted into a cell phone that would quickly identify and count the cells within the sample. The read-out could be sent wirelessly to a hospital for further analysis. This could have significant impact on medical diagnostic procedures related to health problems such as HIV or malaria.
