With Blood pH, you can quickly determine the acid-base disorders of your patient, follow their evolution graphically, and see whether it’s adequately compensating for them. If it is not, Blood pH will also report the disturbance that’s preventing this. All this information is inserted visually, in a beautiful interactive graph, in order to let you better understand what’s happening. When appropriate, Blood pH also lets you calculate the Anion Gap or the A-a Difference, to obtain a better characterization of the source of the disturbance. Features: - Interactive color graph where you can plot, with a touch of the screen, your patient’s disturbance and see the relationship between pH, PaCO2, HCO3 and Standard Base Excess. - Choose between the physiological model (HCO3) or Standard Base Excess for plotting and calculate the disturbance. - Store previous disturbances and plot them on the screen to follow their evolution - Grayscale version of the graph, with increased contrast between elements - Share the color or grayscale graph as a PDF - Context sensitive Anion Gap and A-A Difference calculators to better characterize the disturbance - Insert pressures as mmHg or KPa - The A-a Difference calculator can use your current atmospheric pressure to improve its accuracy - Universal App with iPad and iPhone support
