Ease the stress and get your confidence back when administering high-risk medication with the Certa Dose App! We provide visual verifies each step of the way to secure the right outcome. Explore the features during the 14-day free trial period and add peace of mind to your daily practice. The Certa Dose app allows you to go through the process of medication administration in less than 60 seconds with a visual representation of everything that you do. You will be able to estimate weight-based dose using multiple options, choose the right syringe, visualize the correct volume of the medication concentration and document sessions seamlessly. HCPs working in emergency care are under a lot of stress—it can be easy to lose track of the various steps of proper measurement of medicine, get distracted, misplace a decimal point, and make a mistake while the patient is in a critical state and the healthcare provider is under stress—mistakes happen and these situations are one of the leading causes of critical dosing errors. That is why we believe visualization features can help medical professionals double-check their work and make sure they clearly see the amount of medicine they intend to administer. The mission of the Certa Dose app is to empower medical professionals to be aware and mindful while measuring medication so they can avoid medical dosing errors.
