The CPU board (part number 4-075726-30) of the Covidien PB840 ventilator is a key component of the device, managing its operational processes and user interface. The PB840 ventilator is suitable for invasive and non-invasive ventilation in a variety of clinical settings to provide patients with essential respiratory support.

The CPU board is responsible for processing data from sensors, controlling ventilator functions, and enabling communication between different components of the device. It plays a vital role in ensuring accurate ventilation therapy, monitoring patient parameters, and compliance with safety standards.

If the CPU board fails or fails, the ventilator may lose functionality, so maintenance and replacement are critical. This component is designed to provide high reliability and performance to support critical care environments.

► Introduction of Puritan Bennett 840 ventilator

The Puritan Bennett 840 ventilator consists of a Breathing Delivery Unit (BDU) that controls ventilation, and a Graphical User Interface (GUI) for monitoring and displaying ventilator and monitoring data (see Figure 1). The ventilator delivers either mandatory breaths (pressure or volume controlled) with preset oxygen concentrations or spontaneous breaths (inspiratory flow up to 200 L/min, with or without pressure support). Breaths can be triggered by pressure or flow (using the Flow-by feature).
