Laryngospasm

the difficulty of intubationand can be toggled on or off.
To activate the laryngospasm feature:
1. Enable Laryngospasms in the Maestro software. Tap the Respiratory icon on the SCE run
screen.

Bronchial Resistance
The Aria configurations include a variable bronchial resistance feature that is software-controlled.
To control bronchial resistance in the software:
1. Tap the Respiratory icon on the SCE run screen.
2. Tap on Bronchial Resistance Factor: Left or Bronchial Resistance Factor: Right and
adjust the settings as desired.
Resistance settings can be toggled from 0.20 - 250000.00 (Default: 1.00)
A setting >=5 will result in moderate resistance.
A setting >=50 will result in occlusion.
The user can also induce bronchial occlusion by tapping the Left or Right bronchial occlusion toggle
ON or OFF (Default: OFF).
Note: When bronchial occlusion is enabled, unilateral chest excursion can be observed during
spontaneous or positive pressure ventilation.
Gastric Distention
During esophageal intubation or overly aggressive bag-valve-mask ventilation, gastric distention
occurs. Gastric distention is relieved by putting pressure on the abdomen.
