No ads just basic functionality very nice design simple for anyone to use and very basic works anywhere on the go. Fixes a lot of common mistakes that most calculators have. Anyone can use it anywhere. Design is very fluid meant to flow as you go. Also has a nice parallax effect it feels exactly like you are holding a sheet of glass in your hand! A competently different focus compared to other Calculators out there! Simply it just works!

The NeoCardioLab is a research laboratory interested in clinical and epidemiological neonatal cardiovascular research, as well as education in neonatal hemodynamics. The principal investigator of the NeoCardioLab is Dr. Gabriel Altit from the Montreal Children’s Hospital (at McGill University). On the NeoCardioLab website, we have made available for the learners a whole array of content (clips, videos, presentations, reading material, articles, etc.) as a learning opportunity on echocardiography (2D and 3D), TnECHO (targeted neonatal echocardiography), point of care ultrasound (POCUS) and near infrared spectroscopy (NIRS). You will find on the website, our comprehensive “Atlas” for the expected normal complete neonatal echocardiography (with clips of various views and explanations), as well as clips for selected congenital heart defects. Our training modules are: on NIRS in the neonatal intensive care unit, as well as on POCUS/TnECHO. We offer modules on TnECHO (Targeted Neonatal Echocardiography; with clips outlining all the views and measurements, pulmonary hypertension, PDA, normative values, etc.), POCUS (as well as the example of the use of a hand-held device and how to obtain views) and Congenital Heart defects, as well as modules on Strain/Speckle Tracking and Near Infrared Spectroscopy. We also now host the Neonatal NIRS consortium page and all the recordings of their webinars. Please feel free to navigate the app and use it for training purposes and as a resource to complement your other learning materials. We are constantly updating the website and adding new content. You will also find information on the McGill University Neonatal Hemodynamics Clinical Research training program, if you are interested. Our research uses conventional and advanced echocardiography (speckle-tracking echocardiography on 2D and 3D acquisitions) to better understand the cardiovascular adaptation of newborns with various conditions (such as: prematurity, bronchopulmonary dysplasia, congenital heart defect, congenital diaphragmatic hernia, omphalocele and hypoxic ischemic encephalopathy). We also study cohorts of patients once they have graduated the neonatal intensive care unit (in neonatal follow-up, in the pediatric clinics, as well as during adulthood). Please feel free to contact us if you have questions or suggestions: info@neocardiolab.com. We also have Twitter (@CardioNeo) and Instagram (@NeoCardioLab).
