A method and apparatus to regulate the inflation of objects. To start inflation, the apparatus couples a fluid source to the object via a plenum. Concurrent with inflation, the apparatus substantially continuously measures pressure within the plenum using a sensor sufficiently proximate the object such that pressure measured by the sensor is substantially similar to pressure within the object. When measured pressure exceeds a target pressure by a prescribed margin, the apparatus stops inflating. While inflation is stopped, the apparatus reads pressure measured by the sensor and deflates the object as needed to reduce measured pressure to the target pressure.
