Conclusion:

NIMV-induced regularized breathing at typical subject’s own free breathing frequency and NIMV-induced regularized breathing at 5 breaths per minute can increase expiratory gating efficiency, showing potential to improve expiration gating radiotherapy.

Keywords: Expiration gating, non-invasive ventilation
