Resuscitation device with onboard processor

A resuscitator comprising:

• a patient airway interface device;
• a bag;
• a flow passage coupled between the bag and patient airway interface device;
• and
• a sensor assembly comprising:
• an indicator;
• at least one sensor coupled to the flow passage and configured to provide a measurement of at least one parameter;
• and
• a processor coupled to the indicator and the at least one sensor, the processor configured to receive the measurement from the at least one sensor and actuate the indicator based on the received measurement.

A pressure sensor comprising:

• a substrate;
• a wall formed on the substrate;
• one of a plurality of concentric conductive rings and a plurality of radial conductive strips is formed on the substrate within the wall;
• a flexible disk coupled to the wall so as to form an interior volume;
• and
• the other of the plurality of concentric conductive rings and the plurality of radial conductive strips is formed on the disk,
• wherein deformation of the flexible disk due to a pressure differential between a first pressure within the interior volume and a second pressure outside of the internal volume will cause at least one of the radial conductive strips to contact at least one of the concentric conductive rings.
