Evaluation: Medtronic Puritan Bennett 980 Intensive Care Ventilator
September 12, 2018 | Evaluations & Guidance
- The Medtronic Puritan Bennett 980 is an intensive care ventilator—a critical life-support device that delivers positive-pressure breaths to patients who require total or partial assistance to breathe.
- This model can also be used noninvasively as an oxygen (O2) therapy device, in which O2 is delivered via a mask, hood, or nasal cannula to patients who can breathe on their own.
Major hardware device components and software features include:
- Primary display—A 15-inch graphical user interface (GUI) that includes a touchscreen and eight off-screen control keys. The primary display can be rotated 340° around the center and tilted up to 45° from vertical. The GUI displays device settings, patient data and waveforms, and active alarm banners. The off-screen control keys are display brightness, inspiratory pause, display lock key, expiratory pause, alarm volume, alarm reset, manual inspiration, and alarm silence. A rotary encoder (knob) is also included to facilitate adjustment of ventilation parameters and alarms.
- Breath delivery unit subsystem—The unit producing the artificial respiration.
- Status display (clinical use mode)—A five-inch display on the breath delivery unit that shows the following:
- Safe State status (Safety Valve Open SVO or Vent Inop)
- The current power source (AC or DC)
- The presence of primary and extended batteries and their charging status
- Relative available battery charge level(s)
- Gas supply connection status
- Measured peak patient circuit pressure (updated at the end of each breath)
- A graph of measured inspiratory pressure (updated as pressure changes)
- Measured positive end-expiratory pressure (PEEP)
- Alarm setting for peak pressure
- System alarm volume setting
- Status display (service mode)—In service mode, the status display shows the following:
- The device serial numbers
- Operational time
- Extended and short self-test histories
- Power On Self Test (POST) status
- Hours until next preventive maintenance due
- Gas supply pressure at the manifold inlets
- Extended battery backup—Two lithium-ion battery slots in the breath delivery unit allow placement of a primary and a secondary backup battery. Batteries for the PB 980 are hot-swappable—that is, capable of being removed and replaced during active ventilation.
- Cart—A base with casters on which the breath delivery unit and GUI can be mounted. The PB 980 can also be mounted as a freestanding unit at the patient's bedside.
