Mean Arterial Pressure (MAP)
Hemodynamic assessment & BP emergencies
▾
Enter Blood Pressure
Normal MAP:
• 70–100 mmHg (adequate organ perfusion)

Hypertensive Urgency:
• Reduce BP gradually over 24–48 hours
• No immediate MAP target
• Avoid rapid reduction

Hypertensive Emergency:
• Reduce MAP by ≤25% in first 1 hour
• Then target BP ≈ 160/100 mmHg over next 2–6 hours
• Further gradual reduction over 24–48 hours

Thalassemia trait vs Iron Deficiency Anemia
▾
Enter CBC Values
Formula: MCV ÷ RBC count

< 13 → Thalassemia trait likely
> 13 → Iron Deficiency Anemia likely

Screening tool only — confirm with iron studies / Hb electrophoresis
Oxygen Cylinder Duration
Estimate remaining oxygen time at given flow rate
▾
Cylinder details
Pressure unit instructions:
• DO NOT enter PSI
• Enter pressure in bar or kg/cm² only
• 1 bar ≈ 1 kg/cm² (≈2% difference, clinically acceptable)

How to identify cylinder type:
• Printed / engraved on cylinder body or neck
• Supplier label or color code (varies)

Clinical notes:
• Calculation is approximate
• Humidifier, leaks, NRBM/HFNC reduce duration
• 20 bar kept as safety reserve
• Do not run cylinder to zero
ABG Interpretation (Advanced)
Primary disorder, compensation & mixed states
▾
Enter ABG values
Normal reference:
• pH: 7.35 – 7.45
• PaCO₂: 35 – 45 mmHg
• HCO₃⁻: 22 – 26 mEq/L

Note: This advanced tool checks expected compensation to detect mixed acid–base disorders.
CHA₂DS₂-VASc Score
Stroke risk & anticoagulation in Atrial Fibrillation
▾
Sex
Risk factors
Age
Stroke / TIA / Thromboembolism
CHA₂DS₂-VASc Score = 0
Low risk. No anticoagulation required.
HAS-BLED Score
Bleeding risk assessment in AF
▾
Select bleeding risk factors
Important:
• Score ≥3 = High bleeding risk
• NOT a reason to stop anticoagulation
• Correct reversible risk factors and monitor closely

Tenecteplase (TNK) ▾

Single IV bolus (no infusion)
ST-Elevation Myocardial Infarction (ESC 2023)
• IV bolus over 5–10 sec
• <60 kg → 30 mg (6000 U)
• 60–69 kg → 35 mg (7000 U)
• 70–79 kg → 40 mg (8000 U)
• 80–89 kg → 45 mg (9000 U)
• ≥90 kg → 50 mg (10,000 U)
⚠️ Age ≥75 years → Half dose
Acute Ischemic Stroke (ESO 2023)
• 0.25 mg/kg IV bolus
• Maximum dose: 25 mg
Pulmonary Thromboembolism
• Weight-based dosing (same as STEMI)
• ⚠️ Guidelines still prefer Alteplase

Ganzoni formula · Adult & Pediatric
▾
Patient category
Sex
Clinical details
Formula:
Iron (mg) = Weight × (Target Hb − Actual Hb) × 2.4 + Stores

Assumptions:
• Adult target Hb: Male 15 · Female 14
• Pediatric target Hb: 13
• Stores: Adult 500 mg · Pediatric 15 mg/kg (max 500)

Practical caps:
• Adult: max 1500 mg per course
• Pediatric: max 20 mg/kg
RBS Sliding Scale Insulin (IPD)
6-hourly · Regular Insulin · Adult (0–4–6–8–12–16–20 scale)
▾
Protocol (Adult IPD · India):
≤ 150 0 units 151 – 200 4 units 201 – 250 6 units 251 – 300 8 units 301 – 350 12 units 351 – 400 16 units > 400 20 units + Call
Enter Random Blood Sugar (mg/dL)
Assumptions:
• Patient is off OHA, no basal insulin.
• CKD excluded (requires dose reduction).
• Use Regular insulin (SC).

Safety:
• RBS < 70: Stop insulin, treat hypoglycemia.
• RBS > 400: Check ketones, evaluate for sepsis/steroid effect.
