Background: Ventilation with lower positive end–expiratory pressure (PEEP) may cause loss of lung aeration in critically ill invasively ventilated patients. This study investigated whether a systematic lung ultrasound (LUS) scoring system can detect such changes in lung aeration in a study comparing …

Around 60% of drinking water in the Netherlands is from groundwater, often containing high concentrations of dissolved iron. This is generally removed by aeration, which is an important process in both drinking- and waste water treatment. The known disadvantages are high energy consumption relative to …
