1. Capnodynamic determination of effective pulmonary blood flow and end expiratory lung volume : studies in children and paediatric animal models
Sammanfattning : Dynamic capnography is a haemodynamic and respiratory monitoring technique enabling continuous cardiac output (Effective Pulmonary Blood Flow, COEPBF) and end expiratory lung volume (Effective Lung Volume, ELV) assessment in mechanically ventilated subjects. The method utilizes variations in exhaled CO2, implemented via periods of deliberate changes in the respiratory pattern. LÄS MER
2. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies
Sammanfattning : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. LÄS MER
