From: Upper airway resistance during use of a laryngeal mask airway is flow-dependent and dominated by the laryngeal resistance

Fig. 4

Resistance diagrams. (a) Resistance (R) of different sizes of laryngeal mask airways (LMA#) and (b) different vocal cord angles (VCA) in dependence of flow. (c) Combined resistance of laryngeal mask airway size 4 (LMA#4) and different vocal cord angles (VCA) in black. Grey lines represent the results of the mathematical summation of the single resistance of LMA#4 and the corresponding VCA (calc). Note the completely overlaying graphs of measured and calculated resistances for vocal cord angles higher than 30°.
