[0] Airway Resistance [1] 2-5 cmH2O/L/sec [2] <15 cmH2O/L/sec [3] 
There are two kinds: Mean Airway Resistance - the result of friction in the patient airways and endotracheal tube throughout the entire respiratory cycle. Expiratory Airway Resistance is the result of friction in the patient's airways, endotracheal tube and expiratory limb of the ventilator circuit during expiration only. Airway resistance normally varies inversely with lung volume and increases in obstructive and reactive airways disease. It increases rapidly with decreases in ET tube size as a result of Poiseulle's Law.
