This is an all-in-one pediatric tool. Select the patients age and it will calculate the weight. You can override the weight with your own selection. Now, you can get weight and age-specific information for your patient: ETT size, depth, fiberoptic selection, LMA size and fluid requirements. You can get weight-specific drug dosing, including cardiac medications. With this one app you will have all the information you need to take care of a newborn, or other small patient. There will no longer be a need to look up multiple formulas and sizing equations. Nothing has been simpler!
