          byDefault = pressure.default,
          own = pressure.new("ownInstance", {
                  memoryThreshold: 200 * 1000000, //200MB
                  interval: 1000, //1sec
                  stillUnderPressure: 20, //If still blocked after 20 check calls, emits `stillUnderPressure` event
                  consecutiveGrowths: 5
          });
     
    byDefault.on("underPressure", function (memoryUsage) { //memoryUsage is the object returned by process.memoryUsage()
        //Do some stuff to release pressure
        pressure.default.ack(); //Ready for next state (required)
    });
     
    byDefault.on("stillUnderPressure", function (memoryUsage) { //This event is emitted if you did not manage to release memory after `underPressure` event
        pressure.default.ack(); //Ready for next state
    });
     
    byDefault.on("pressureReleased", function (memoryUsage) {
        pressure.default.ack(); //Ready for next state
    });
     
    pressure.ownInstance.on(...,...);
