With the use of laryngeal mask airways (LMAs) on the rise and growing clinical interest in supporting spontaneous breathing for ventilated patients, GE Medical Systems' Healthcare's Datex-Ohmeda responded with innovative modes of anesthesia ventilation to meet these needs. Now available as options for the Anesthesia systems with 7900 SmartVent™, SIMV and PSVPro™ modes expand the capabilities of the system and help simplify the care for a broad range of patients. SIMV, or Synchronized Intermittent Mandatory Ventilation, provides a set number of ventilator-delivered breaths per minute. SIMV allows ventilator to sense patient’s own breathing and permit spontaneous breathing between mechanical ventilations while assuring sufficient mandatory breaths should the patient’s own rate fall below a preset value. SIMV is helpful when the patient's rate and tidal volume change due to the depth of anesthesia, the patient's needs change during surgery, or the patient is adjusting to different phases of anesthesia. Pressure Support Ventilation (PSVPro™) option is a spontaneous mode that provides the set amount of pressure to the patient during each triggered breath or, if the patient does not have any spontaneous breaths in a set period of time, the ventilator transitions to SIMV-PC where it delivers a minimum number of mechanically controlled breaths. The Apnea Backup Mode is designed to ensure a minimum ventilatory status. With full patient range capability, an adjustable flow trigger, PEEP and an Apnea Backup Mode, the PSVPro™ (Pressure Supported Ventilation) mode helps simplify the work of caring for your spontaneously breathing patients. |
