Huppert's Notes Internal Med.

Read full description

Bridge the gap between pathophysiology and clinical medicine in a succinct outline of core internal medicine topics! Originally created and road-tested by a resident and then updated by a team of resident authors, Huppert’s Notes succinctly organizes the foundational science covered early in medical school and the clinical approaches encountered in clerkships and beyond. This marriage of pathophysiology and clinical medicine provides a framework for how to approach internal medicine concepts mechanistically, rather than through memorization. You’ll find concise descriptions of common medical conditions with diagnostic and management pearls, as well as high-yield diagrams and tables to emphasize key concepts. Covering all internal medicine subspecialties, each Huppert’s Notes chapter is organized in an intuitive and consistent outline format for rapid access: β€’ Anatomy & Physiology β€’ Diagnostics β€’ Approaches & Chief Complaints β€’ Diseases & Pathophysiology β€’ Key Medications & Interventions β€’ Key Clinical Trials & Publications After the app has been downloaded, no internet connection is needed to retrieve the content of the app. All of the text, images and tables are available to you on your device anytime, anywhere, and lightning fast. This app is also automatically optimized for whatever size device you are currently using, either phone or tablet. This interactive app contains the full content of Huppert's Notes: Pathophysiology And Clinical Pearls For Internal Medicine by McGraw-Hill Education.

About

ACLSMED CPR

Features
Read full description

Put the phone under your hands. Press START. Do CPR on a manikin β€” and see exactly how you're doing. ACLSMED CPR turns an iPhone into a chest-compression training sensor β€” on its own, or paired with ACLSMED Sim on iPad for the full classroom experience. The phone lies flat on the manikin's sternum, your hands go on top of it, and the motion sensors measure every compression in real time. ***FOR TRAINING ONLY β€” MEDICAL DISCLAIMER*** For education and simulation on a manikin only. Not for use on a real patient. ACLSMED CPR is a training aid, not a medical device, and does not provide medical advice, diagnosis, or treatment. Always seek the advice of a doctor or other qualified health provider in addition to using this app, and before making any medical decisions. In a real emergency, call your local emergency number immediately. HOW IT WORKS β€’ Place the phone flat on the manikin's chest, hands on top, start compressions β€’ A 110-per-minute metronome keeps your rhythm β€” the one cue that reaches you while your hands are on the phone β€’ Stop and get a debrief: quality score, compression count, rate, depth zone, and hands-on time WHAT IT MEASURES β€’ COMPRESSION RATE β€” against the 100–120 per minute training target β€’ COMPRESSION DEPTH β€” shown as honest red/amber/green zones β€’ CHEST COMPRESSION FRACTION β€” the share of time your hands stay on the chest β€’ An overall 0–100 quality score computed from the session's rolling averages BUILT FOR THE ACLSMED SIM ROOM Join your class on ACLSMED Sim for iPad (separate app): scan the QR code or type the 6-digit class code from the instructor's iPad, and your phone works only with that class: β€’ Your live red-to-green quality bar appears on the patient monitor β€” where the room is already looking β€’ Real compressions drive the monitor's ECG artefact and vitals, and your hands-on fraction lands in the code debrief β€’ CPR SIMULATOR mode: up to six phones at once in a two-minute timed test, with ring-gauge results and a class leaderboard on the shared iPad β€” and each student's grade delivered to their own phone β€’ Connects over your local network, and falls back to direct device-to-device Wi-Fi and Bluetooth when there's no router WORKS ON ITS OWN No iPad? The phone still measures, keeps the beat, counts compressions, and scores your session. HONEST BY DESIGN Published phone-sensor depth accuracy is about Β±5 mm against a target window only 10 mm wide β€” so ACLSMED CPR shows depth as zones and scores rolling averages instead of pretending to millimetre precision. What a phone cannot measure honestly (like chest recoil), it does not score. PRIVATE BY DESIGN No account. No ads. No analytics. Nothing is collected or sent to any server β€” your name and readings go only to the ACLSMED Sim room on your local network, and only if you join a class. The camera is used only to scan a class code; nothing is recorded. Requires iPhone with iOS 17 or later. Joining a class needs ACLSMED Sim 2.6.1 or later on the iPad. ACLSMED Sim for iPad is a separate app; its CPR Simulator test mode requires a Pro or Clinical Suite plan. LEGAL https://www.aclsmed.com/privacy.html https://www.aclsmed.com/terms.html
