Donor-Recipient Size Matching Calculator
pTLC ratio, disease-specific modifiers, lobar segment adjustment, and surgical warning flags for lung transplant donor review.
Procedure Type
Donor Demographics and pTLC
Weight is displayed for review but not used in ERS 1995 pTLC.
Leave blank to calculate from sex and height.
Recipient Demographics and pTLC
Weight is useful clinically and for BMI review but not used in ERS 1995 pTLC.
Leave blank to calculate from sex and height.
Optional but useful in ILD/COPD to assess chest distortion.
Lobar / Segmental Graft
Whole bilateral lungs = 18 segments. Example: left lung + RLL = 13.
Heart-Lung Block
Anatomic and Access Modifiers
Clinical note: This is a decision-support prototype, not a replacement for multidisciplinary transplant donor review. It uses pTLC ratio thresholds and modifiers derived from the AATS 2026 expert consensus document on donor-recipient size matching. Centres may override pTLC values if they use GLI or local equations.
Primary Graft Dysfunction Calculator
| PGD Grade | CXR Infiltrates | PaO2/FiO2 Ratio |
|---|---|---|
| Grade 0 | No | Any |
| Grade 1 | Yes | > 300 |
| Grade 2 | Yes | 200-300 |
| Grade 3 | Yes | < 200 |
Based on the 2016 ISHLT PGD definition. If PaO2 is entered in kPa, it is converted to mmHg using kPa x 7.5. PGD should be assessed at T0, T24, T48, and T72. ECLS/ECMO for hypoxemia with infiltrates is classified as PGD Grade 3.
CLAD Surveillance Tool
Upload a text-based PFT PDF or manually enter post-transplant spirometry values. Baseline FEV1 is calculated as the mean of the two highest FEV1 values entered.

CLAD should only be confirmed after excluding reversible causes such as infection, acute cellular rejection, antibody-mediated rejection, airway complications, pleural disease, fluid overload, or poor-quality spirometry.
