How Much Time Do I Have to Say a Berakhah?

I was recently at a sporting event where the line to exit the bathroom took close to five minutes. How long following an action or event requiring a berakhah can you still make the berakhah? How does one behave while waiting for the opportunity if you are conscious of the fact that you need to make the berakhah but are temporarily unable and what ultimately severs the connection to the berakhah?Have a question you'd like answered on Responsa Radio?
