Characteristics of the volume flux waveform, including the fundamental frequency, f, duration of the open phase T_o, rising and dropping time of Q during the open phase, T_p and T_n, and the ratios τ₀=T_o∕T, τ_s=T_p∕T_n, and q_r=Q_mean∕Q_max. The units are kPa for P₀, Hz for f, ms for T_o, T_p, and T_n, and cm²∕s for Q_max and Q_mean.
