The Difficult Airway App (v.3.3) The Difficult Airway App™ is an essential tool for clinicians who manage emergency airways in any setting: the ED, ICU, in-patient unit or the many EMS practice environments. THE RIGHT DRUGS, THE RIGHT DOSES, THE RIGHT WAY! This app rapidly and easily selects the right drugs for RSI, automatically adjusting for obesity and hemodynamics. Pediatric dosing and equipment selection is a snap using the Broselow-Luten color system or the child's estimated weight. Stay out of trouble! The Difficult Airway App™ guides the user quickly and easily through important algorithms, predictors of the difficult airway, and the step-by-step approach to RSI taught in The Difficult Airway Course: Emergency™. The Difficult Airway App™ features: EASY, YET SOPHISTICATED ADULT AND PEDIATRIC DRUG DOSING • For adult dosing, a few simple clicks bring you to recommended doses that incorporate patient weight, body habitus and hemodynamics. • The pediatric drug dosing function incorporates the color-coded system created by James Broselow, MD and Robert C. Luten, MD for rapid, safe management of pediatric airway cases. • The option to customize your formulary means that only the drugs you use will appear in the recommendations. DECISION-MAKING SUPPORT • Straight-forward algorithms allow you to quickly determine the best approach to your patient’s airway. • Easy mnemonics walk you through predictors of a difficult airway, including difficult laryngoscopy (LEMON), difficult BMV (ROMAN), difficult extraglottic device use (RODS) and difficult cricothyrotomy (SMART). • Pearls of wisdom, based on evidence and expert opinion, are offered throughout. RAPID SEQUENCE INTUBATION • The 7 – Ps of RSI: a step-by-step guide for adult and pediatric patients. • Adult and pediatric RSI drug dosing. EDUCATIONAL RESOURCES • Richly detailed illustrations of the airway anatomy. • Links to information about The Difficult Airway Courses™. Created by Ron M. Walls, MD, Michael F. Murphy, MD and Robert C. Luten, MD. With significant updates by Calvin A. Brown III, MD.

In addition to The S.T.A.B.L.E. Program Module Guidelines: Sugar, Temperature, Airway, Blood pressure, Lab work, Emotional support for the family, this app includes a BONUS menu of 22 severe cardiac anomalies to increase understanding of how blood flows through the heart in the setting of ductal dependent and not ductal dependent congenital heart disease (CHD). - 4 calculators: corrected gestational age, temperature converter (Fahrenheit to Celsius and vice-versa), umbilical artery and venous catheter insertion depth, weight converter (grams to pounds/ounces and vice-versa). - Under Cardiac Anomalies you’ll find animations and information on 22 severe forms of congenital heart disease. The MP4 videos demonstrate how blood flows through the heart with the various forms of CHD, and for ductal-dependent lesions, the severe impact of ductal closure on blood flow. Other animations feature normal heart anatomy, hypercyanotic (tet) spell, and balloon atrial septostomy (Rashkind procedure). Also included are illustrations of palliative procedures (PDA stent, balloon valvuloplasty, BT shunt, RVOT stent, central shunt, pulmonary artery band). STABLE stands for the 6 assessment and care modules in the program: Sugar, Temperature, Airway, BP, Lab work, Emotional support. This app includes the following items: - Sugar module: General Guidelines for sick infants and infants at increased risk for hypoglycemia, IV treatment of a blood sugar less than 50 mg/dL (2.8 mmol/L), useful information about umbilical catheters and actions to correct umbilical artery catheter malpositions. - Temperature module: General Guidelines (hypothermic classifications, monitoring, rewarming after accidental hypothermia), and neuroprotective hypothermia checklist and neurologic exam. - Airway module: monitoring guidelines, respiratory distress descriptions, endotracheal tube sizes and insertion depth, blood gas evaluation, signs of a pneumothorax, and treatment of a pneumothorax. - Blood pressure module: assessment for shock and treatment of shock, including how to mix dopamine hydrochloride to constitute an 800 microgram/mL IV fluid solution. - Lab work module: risk factors for neonatal infection, clinical signs of infection, and laboratory evaluation prior to transport to an intensive care unit. How to calculate the absolute neutrophil count and immature to total ratio. - Emotional support for the family module: the various emotions that parents may be experiencing and how to help families who are experiencing the crisis of a sick newborn. The Cardiac Anomalies menu includes short descriptions and MP4 videos and illustrations for: - Normal Heart and Lungs - Aortic Valve Stenosis - Atrial septal defect - Atrioventricular canal - Coarctation of aorta - Double outlet right ventricle - Ebstein anomaly - Hypoplastic left heart syndrome - Interrupted aortic arch – type B - Patent ductus arteriosus - Pulmonary atresia with intact ventricular septum (IVS) - Pulmonary atresia with IVS and sinusoids - Pulmonary atresia with ventricular septal defect - Total anomalous pulmonary venous connection (TAPVC) – Cardiac, Supracardiac, Infracardiac) - Tetralogy of Fallot (moderate stenosis) - Tetralogy of Fallot (ductal dependent) - Transposition of the Great Arteries - Tricuspid atresia - Truncus arteriosus - Ventricular septal defect Includes illustrations of palliative procedures: balloon atrial septostomy (Rashkind procedure), PDA stent, balloon valvuloplasty, Blalock-Taussig (BT) shunt, right ventricular outflow tract (RVOT) stent, central shunt, pulmonary artery band.
