Fig. 1From: Impact of pressure-targeted modes of ventilation on diaphragmatic function as assessed using ultrasonography in critically ill patients with cerebral insult: a randomized clinical trialThe ultrasound diaphragmatic assessment. A and B To assess the DE, the right hemidiaphragm was identified. Then the M-mode was activated. C and D The DFT was assessed by calculating the ratio of the increase in diaphragmatic thickness at the end of inspiration compared with that at the end of expiration. DE, diaphragmatic excursion; DTF, diaphragmatic thickness fractionBack to article page
