I:E — Toggle Ti / I:E / Peak Flow

Controls

Mode: Set Tᵢ

Respiratory Rate (breaths/min)

5–40 bpm

Current: 14 bpm

Inspiratory Time T_i (s)

Auto-limits so T_e ≥ 0.30 s

Current T_i: 1.40 s

I:E: 1:2.00

Tidal Volume (mL)

200–800 mL

Current VT: 500 mL

Bar length reflects T_tot (shorter at higher RR). Segment widths reflect T_i and T_e.

I Flow (peak) ≈ 42.9 L/min

E Flow (peak) ≈ 21.4 L/min

Triangles sized so area = VT; peaks scale with Ti/Te and VT.

Total Cycle Time (T_tot)

4.29 s

Inspiratory Time (T_i)

1.40 s

Expiratory Time (T_e)

2.89 s

I:E Ratio

1:2.06

Timing: T_tot = 60 / RR; T_e = T_tot − T_i; I:E = 1 : (T_e/T_i).

Flow triangles: (½·Peak·T) = VT (L). Peaks shown in L/min.
