Quantitative Acid Base Analyser Download now and take your Acid Base Analysis to a new and quantitative level! Completely Free! ------------------------------------------------------------------ QABA is designed for Anaesthetic/ICU Consultants and Registrars, but may also be useful for other health and veterinary professionals QABA allows you to enter the blood results and quickly analyse the Acid Base disturbance as per a refinement of the Quantitative Acid Base Analysis introduced by P. Stewart in 1978 The App features: 'swipe' buttons for quick data entry, a colour coded results screen, with a text report & Gamblegram. The App also includes a brief introduction to understanding QABA and a User Guide. Just enter the levels of sodium, potassium, chloride, pH, CO2 and the App will calculate the results of the 3 independent variables that control blood plasma pH; CO2 Strong Ion Difference (SID) and Weak Acids (Atot), NB: Atot requires at least Albumin or Total Protein level. The app will also display the Net Unmeasured Ions (NUI). NUI is an advancement on the Strong Ion Gap used in Stewarts original equations which is comparable to the Anion Gap used in traditional acid base analysis. For added Analysis accuracy QABA can also accept the phosphate, ionised calcium, magnesium, sulphate, lactate, urate, albumin and total protein levels. This App is based on version 11.6 of the P Lloyd 'Quantitative Acid Base Analysis' in use at Hawkes Bay hospital, New Zealand. The App was written by Dr C Donald and supervised by Intensivists Dr M Park and Dr R Freebairn. ------------ Disclaimer Every effort has been made to make this anylser an accurate and useful clinical tool. However the results must be considered alongside the clinical context and the user assumes all liability/responsibility for the clinical decisions made based upon QABA's results

About

S

Read full description

SSMART (Stanford Surgical Mobile Assessing Risk Tracker) is a smartphone-based health app for a research study by the VA Palo Alto and Stanford University. SSMART acts as a platform to track surgical patients across a highly structured episode of care, their relationship between opioid use and pain, and self-reporting health-related symptoms. This app integrates with HealthKit, ResearchKit and CareKit, as well as the Apple Health App to collect data related to your medical condition, activity and general health.   Since SSMART is a research study based health app, the first step is for users to go through a consent process to participate in the research study; users may also withdraw from the study at any time as they please. Once user consent is given, SSMART will use the mobile health capabilities of a smartphone to access daily activity measures of patients with differing degrees of surgical procedures, once . Users that participate in the study will be asked to complete short assessments on their biopsychosocial behavioral patterns, medication and prescription details, and metrics related to pain, sleep, quality of life, daily functioning. These surveys will be staged pre- and post-surgery in different frequency patterns, as well as are presented to the user optionally. By using CareKit, users are given an easy way to track their health over time as well. Altogether, SSMART is a platform that allow physicians to better help their patients, but it is important to note SSMART does not give health advice. If health advice is needed, it is advised to visit VA Palo Alto Healthcare’s site: paloalto.va.gov.   Survey responses are saved in a secure and HIPAA compliant database. Medical professionals from Stanford Medicine and the VA Palo Alto that have approval for this study through the IRB will be the only ones to receive access to this data .All the information the patient provides will be used by the physician to monitor the patient’s overall health through the backend analytic web app.

Verdict

The call

QABA and S are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
