With growing complexity in deciding on stroke treatment, there is a need for automated system. To be used by physicians to recheck their own treatment decisions. This was the idea behind this app. In a wizard-like approach, it will guide physician to the next step. What imaging will need to be done, at the end it will give you suggestions if patient is a tPA or thrombectomy candidate and more importantly it will tell you why. Stroke patients don't present with just stroke. Many times we run into situations where there is a tPA candidate but had a procedure, pregnant, menstruating, had a central line or hemodialysis etc. In the "Special tPA Situation" section, you will find extensive list of all situations you may encounter. It also comes with all the stroke scales and scores needed to run a stroke activation. Disclaimer: This application is intended for healthcare professionals only, not intended for use by the public. Seek medical advice in case of stroke symptoms or emergency. All calculations and decisions are only suggestions and must be re-checked by a qualified physician.
