Method, apparatus and computer program for monitoring air pressure change to reduce barotrauma

An apparatus comprising at least one processor and at least one memory including an application that is executable by the at least one processor to cause the apparatus at least to carry out a method for monitoring air pressure change, comprising:

• receiving a user input selecting a pressure monitoring application,
• receiving a user input initiating monitoring of an ambient air pressure by the pressure monitoring application,
• determining a first barometric pressure of the ambient air pressure at a first time,
• determining a second barometric pressure of the ambient air pressure at a second time, wherein the second time is a predetermined time interval from the first time,
• comparing the first barometric pressure with the second barometric pressure to determine a first absolute rate of change of the ambient air pressure over the predetermined time interval, and
• providing an indication to employ protective measures when the first absolute rate of change of the ambient air pressure is equal to or a exceeds a threshold rate of change likely to cause barotrauma.

A nontransitory computer readable medium having a computer program stored thereon that is executable by a processor for causing a portable electronic display device to carry out the method for monitoring air pressure change, comprising:

• receiving a user input selecting a pressure monitoring application,
• receiving a user input initiating monitoring of an ambient air pressure by the pressure monitoring application,
• determining a first barometric pressure of the ambient air pressure at a first time,
• determining a second barometric pressure of the ambient air pressure at a second time, wherein the second time is a predetermined time interval from the first time,
• comparing the first barometric pressure with the second barometric pressure to determine a first absolute rate of change of the ambient air pressure over the predetermined time interval, and
• providing an indication to employ protective measures when the first absolute rate of change of the ambient air pressure is equal to or a exceeds a threshold rate of change likely to cause barotrauma.
