The Philips DreamStation BiPAP ST25/NB is an invasive non-breathing device intended to assist people experiencing breathing challenges, such as sleep apnea and respiratory disease. The BiPAP machine provides two pressure levels—IPAP (inspiratory pressure) to aid inhalation and EPAP (expiratory pressure) to facilitate exhalation. With its Spontaneous/Timed (S/T) mode, the DreamStation provides reliable breathing support through automatic adjustment to natural breathing rhythm as well as timed breaths as indicated. Small, quiet, and patient-oriented, it is perfect for home respiratory therapy and clinic use. Based on Philips Respironics' proven technology, the BiPAP ST25/NB provides comfortable, effective, and consistent therapy to patients requiring additional breathing support.
