Changes in VC, DLCO, DLNO and exhaled breath after an one-hour oxygen dive with a PO2 of 190 kPa as an indication for pulmonary oxygen toxicity.

Primary Objective: 1. Will an exposure to oxygen with a PO2 = 190 kPa lead to changes primarily in DLno compared to DLco?Secondary Objectives: 1. After an exposure to oxygen with a PO2 = 190 kPa for one hour, are the changes primarily located in the…

Respiratory infections in asthma: the role of host defense against infections, allergic inflammation and vitamin D

We hypothesize that local AMPs expression in the airways of patients with asthma is decreased as a result of allergic inflammation. Furthermore, we hypothesize that local AMP expression can partly be restored by vitamin D substitution therapy. We…

Mechanical ventilation comparing high versus low tidal volumes in infants with or without acute lung injury.

The aim of this study is to access the effect of low and high VT (ml/kg) on pulmonary and systemic inflammatory responses and the release of oxygen and nitrogen free radicals in the paediatric patient with and without ALI.

A Cross-over Randomized Controlled Trial; Pulmonary edema detection after fluid loading with blood versus saline in patients after CABG

Cardiac surgery patients are often exposed to blood products perioperatively (18). Due to their underlying cardiac condition and ventricular dysfunction these patients are at an increased risk for TACO.(19) In a *proof of principle* approach we will…
