Paper Analytical Device Reader
Read full descriptionHide full description
This is the automatic image analysis tool for PADs, or Paper Analytical Devices. PADs are a screening tool to identify pharmaceutical tablets or capsules that might be falsified. Because this is a research project aimed at drug quality in low resource settings, there is a limited suite of drugs that can be analyzed--mostly anti-infective drugs used in Africa and "street drugs" in the US. 1) Please contact Dr. Lieberman (lieberman.1"at sign"nd.edu) before you start using this app to make sure it will be suitable for your intended purpose. 2) You need both the PADreader (this app) and the test cards, which you can buy here: https://paperanalytics.org/ 3) Confirmatory testing, eg, HPLC, is necessary before any follow-up actions on suspect products.

While a variety of applications exist to provide educational resources for teaching CPR and assistance tools for those who have already been educated in CPR, this application is a tool to provide untrained people with a guide on how to perform adequate CPR that can be followed-along-with during an emergency situation. This application was developed for and is currently being assessed at the UCSD School of Medicine through an IRB approved study for effectiveness at being able to coach untrained individuals through performing life-sustaining CPR. As the study is not complete and the application is currently for educational and demonstrational purposes only, not to be used in an emergency situation. The application also features instructions on when/how to perform the Heimlich maneuver and to administer Narcan to reverse an opioid overdose. Disclaimer: This app is not a substitute for formal CPR training developed by the AHA. Nor does it constitute any form of CPR certification. To become CPR certified and received formal training, find an AHA course near you. All users without formal CPR certification should seek the advice of a doctor regarding use of this app and the medical decision making contained within. All recommendations contained within this app can be found on the AHA's official website or the Red Cross's CPR instructions webpage.
