Fig. 4From: Factors influencing nasal airway pressure and comfort in high-flow nasal cannula oxygen therapy: a volunteer studyThe EEP of 5 mm nasal cannula with flow rate for different gender. Values are median (IQR). When the target pressure reaches 2 cmH2O and above, the difference of the required flow rate between different genders can be up to 10 L/minBack to article page
