1. A method of analyzing duct pressure within a pipe, the method comprises the steps of:
(A) providing a pressure monitor and a target duct, wherein the pressure monitor is in fluid communication with the target duct, and wherein the pressure monitor includes an alert indicator, and wherein a plurality of situational alerts is stored on the pressure monitor;
(B) periodically capturing a plurality of pressure readings inside the target duct with the pressure monitor;
(C) logging each pressure reading with the pressure monitor;
(D) comparing each pressure reading to each situational alert with the pressure monitor to identify at least one matching alert for at least one specific reading, wherein the matching alert is from the plurality of situational alerts, and wherein the specific reading is from the plurality of pressure readings;
(E) visually and/or audibly outputting the matching alert with the pressure monitor, if the matching alert is identified for the specific reading;
providing an alert notification as one of the plurality of situational alerts, wherein the alert notification includes an irregular window of time; and,
activating the alert indicator with the pressure monitor, if the at least one matching alert includes a high-severity low-pressure alert and a normal operation alert, and if the high-severity low-pressure alert and the normal operation alert elapse within the irregular window of time.
