Classification: CPC A | IPC A

Claim 19:
20. The ventilator system of claim 14, wherein to recover the one or more of the respiratory resistance and respiratory elastance using the respiratory time constant value comprises:
determining the respiratory elastance, E, by: E=Pao(tEOI)−Pao(0)/τ(Q(tEOI)−Q(0))+V(tEOI);
wherein:
Pao(tEOI) is the airway pressure value at the second time;
Pao(0) is the airway pressure value at the first time;
τ is the respiratory time constant value;
Q(tEOI) is the airway flow value at the second time;
Q(0) is the airway flow value at the first time; and
V(tEOI) is the airway volume value at the second time.
