Why are there oscillations in the pressure and flow waveforms?

 

Answer:  Waveform oscillations indicate secretions in the large airways, endotracheal tube or ventilator circuit. These secretions may impair ventilation and should be suctioned.

Large oscillations throughout the breath phase are more likely in proximal airways, and fine oscillations represent more distal secretions.

Alternatively, large oscillations could also represent excess accumulation of ventilator tubing H2O condensate from heated humidification.
