Differences in pressure and comfort between different nasal cannulas
Dyspnea, EEP, dyspnea
When the flow rate reached 30 L/min, the EEP produced by the three nasal cannulas began to differ (5 > 4 > 3 mm, EEP produced by different nasal cannulae in HFNC at different flow ratesValues are median (IQR), The EEP produced by different nasal cannulae in HFNC at different flow rates. # represents We also found a significant difference in EEP between the two sexes when using the 5-mm cannula. When the flow rate was 20 L/min, the EEP was 1.76 (1.19) cmHThe EEP produced by different nasal cannulae for different genderThe value is the median (IQR), # represents the significant difference in EEP between different genders under the same flow rate and the same nasal cannula, The EEP of 5 mm nasal cannula with flow rate for different gender. Values are median (IQR). When the target pressure reaches 2 cmHEIP produced by different nasal cannulae in HFNC at different flow ratesValues are median (IQR), When the flow rate reached 30 L/min, the participants began to experience dyspnea, and the discomfort increased as the internal diameter of the nasal cannula increased (Fig. Dyspnea in different nasal cannulae
