WebJan 1, 2024 · BACKGROUND: The difference between Bohr and Enghoff dead space are not well described in ARDS patients. We aimed to analyze the effect of PEEP on the Bohr and Enghoff dead spaces in a model of ARDS. METHODS: 10 pigs submitted to randomized PEEP steps of 0, 5, 10, 15, 20, 25 and 30 cm H2O were evaluated with the … WebFowler's illustration of the measurement of anatomical dead space, plotting exhaled concentration of nitrogen (C) following an inspired breath of 100% oxygen against exhaled volume (Vexp), where ...
