AVBG Free
Professional Open calculator
Free clinical edition v55.0.7

Read the physiology.
Leave the identity out.

The complete AVBG engine for ABG, VBG, acid–base, compensation, oxygenation and ICU physiology—open to every clinician, with no account and no patient-identifier fields.

Why Free has no patient information

A calculator does not need to know who the patient is.

Age, sex, height and weight can change a calculation. A name, MRN, bed number, hospital or physician does not. AVBG Free therefore accepts the clinical variables the engine needs and deliberately excludes identity fields.

This is not a missing feature. It is the correct boundary for quick bedside reasoning, teaching and anonymous one-case use.

USED FOR PHYSIOLOGYClinical variables
  • Blood-gas and laboratory values
  • Age, sex, height and weight
  • Ventilation and hemodynamic context
  • Optional clinical-condition flags
EXCLUDED FROM FREEPatient identifiers
  • Name or medical record number
  • Bed, location or facility
  • Ordering or treating physician
  • Persistent patient database
No clinical downgrade

The reasoning engine is complete.

Free removes administrative identity and longitudinal record workflow—not clinical interpretation capability.

01

Acid–base architecture

Primary and mixed disorders, expected compensation, anion gap and delta analysis.

CORE
02

ABG + VBG context

Sample-aware interpretation with arterial and venous physiological context.

CORE
03

Oxygenation

P/F ratio, A–a gradient, oxygenation index and ventilation-aware context.

CORE
04

ICU physiology

Respiratory mechanics, O₂ transport, hemodynamic and metabolic inputs.

CORE
05

Anonymous comparison

Sample A versus Sample B in working memory for the current session only.

SESSION
One engine. Two workflows.

Free is for interpretation.
Professional is for accountable workflow.

The paid edition does not buy a “better answer.” It adds the identity, continuity and document controls needed when AVBG becomes part of formal hospital work.

Built to support judgment, not replace it.

AVBG uses named physiological methods and exposes the reasoning behind the output. It remains an interpretation-support tool; laboratory verification, direct assessment and clinician judgment stay essential.

التحليل يحتاج إلى القيم السريرية، لا إلى هوية المريض.

توفر النسخة المجانية محرك AVBG السريري الكامل لتحليل غازات الدم واضطرابات الحموضة والقلوية والأكسجة، من دون تسجيل أو حقول لاسم المريض أو رقمه الطبي أو المستشفى.

أما النسخة الاحترافية فتضيف بيانات المريض وحفظ الحالات والمقارنة والتقارير المهيأة لعمل المستشفى. الفرق في سير العمل والتوثيق، وليس في جودة المحرك السريري.

  • المعالجة اليدوية للقيم السريرية تتم داخل المتصفح
  • لا تُرسل القيم السريرية إلى ENKI Clinical
  • لا تدخل قيم الحاسبة ضمن تحليلات الموقع
  • النسخة المجانية لا تنشئ سجلاً دائماً للمريض
