Summary
To non-invasively estimate the alveolar surface area of the lungs of prematurely born infants by taking measurements of oxygen and carbon dioxide and utilizing functional morphometry.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| OTHER | Calculation of ventilation-perfusion ratio | Three to five paired measurements of fraction of inspired oxygen and peripheral oxygen saturations. Insertion of mainstream capnograph with combined pressure and flow sensor to perform end-tidal capnography measurement. Echocardiogram to assess intra-cardiac shunting. |
