Every clinical reference, organized for the OR.
Helix Anesthesia gives you fast access to the exact piece of information you need at the moment of decision — without the noise.
Multi-turn chat tuned for anesthesia.
Ask about drug interactions, complex case management, regional anesthesia options, ventilator settings, blood gas interpretation, postop pain regimens. Multi-turn context means follow-up questions reference prior turns automatically.
Powered by Anthropic Claude. Built-in PHI detector blocks names, MRNs, dates of birth, and other identifiers before they ever reach the API. Conversation history archived locally on your phone — never stored in plain text on our servers.
Dose, reverse, mix — by weight, age, and procedure.
Sugammadex reversal at TOF / PTC. Pediatric dosing across induction, emergency, antiemetics, MH protocol. Local anesthetic toxicity calculator with max doses and mixing volumes. Continuous infusion rates with on-the-fly unit conversion.
Adult calculators include IBW, ABW, MABL, BMI. Maintenance fluid (4-2-1 / Holliday-Segar) and NPO deficit calculator. Spinal anesthesia dose by procedure type and patient height — bupivacaine, ropivacaine, mepivacaine, chloroprocaine.
Step-by-step protocols for the rarest, scariest moments.
Malignant hyperthermia, LAST, anaphylaxis, can't-intubate-can't-oxygenate, postpartum hemorrhage, AFE, eclampsia. Each protocol shows the full sequence with a built-in event timer at the top.
Tap a step to mark it done. Reset the timer between events. Modeled on the Stanford Emergency Manual structure but reorganized for two-tap access during a real crisis.
Ultrasound-guided blocks with pearls.
Peripheral nerve blocks for upper and lower extremity, truncal blocks for thoracic and abdominal procedures, and neuraxial techniques. Each block shows anatomy diagrams, indications, contraindications, dose ranges, complications, and clinical pearls.
Includes ASRA 2018 anticoagulation timing tables for safe neuraxial placement.
STOP-BANG, RCRI, Gupta MICA — calculated in-app.
STOP-BANG screens for OSA risk in seconds. Lee's RCRI scores cardiac risk for noncardiac surgery. Gupta MICA gives a continuous probability of MI / cardiac arrest based on age, ASA, functional status, surgery type, and creatinine.
Every calculator runs locally on your phone with the published coefficients from the original publication. Citation card on every screen.
Procedure-aware bupivacaine dose, height-adjusted.
Pick the procedure (lower extremity, C-section, lower abdomen, saddle), enter the patient's height, and Helix Anesthesia suggests a dose range with the appropriate target level (T4, T6–T8, T10–L1, S2–S5).
Compares bupivacaine, ropivacaine, mepivacaine, and chloroprocaine side-by-side with duration, pros, cons, and pearls. Includes baricity quick-reference and a checklist of factors that increase block spread.
PALS algorithms — every branch, one tap deep.
Cardiac arrest, bradycardia, narrow- and wide-complex tachycardias, and post-ROSC care. Each algorithm shows the full sequence with weight-based defib energies, drug doses, and reversible-cause checklists.
Same step-by-step structure as the adult crisis checklists, with built-in event timer. AHA 2020 guidelines, reviewed annually.
PPH, eclampsia, accreta, AFE — protocols built for the L&D nightmare.
Postpartum hemorrhage, severe preeclampsia / eclampsia, placenta accreta spectrum, amniotic fluid embolism. Each protocol leads with the most likely cause, the immediate-response checklist, and the drug ladder (uterotonics, magnesium, antihypertensives).
Designed for the chaos of an obstetric emergency: large type, color-coded urgency, drug doses always one tap from the protocol — never buried.
80+ anesthesia abbreviations, fully explained.
Searchable index from ABG to TIVA. Every entry includes the full expansion plus a one-paragraph clinical context. Linked from screens with heavy jargon — Sugammadex, MABL, RCRI — so you never have to leave the app to look up a term.
