Paramedics, pilots and staff from North West Air Ambulance (NWAA) will use Twitter to show people a typical day with the charity.
People will find out about life-saving missions that crews are called to attend and gain an insight into the day-to-day running of the service, which has bases at Blackpool Airport and City Airport, Manchester.
It is the first time the charity has held such an event, known as a tweet day.
Lynda Brislin, chief executive of NWAA, said: "As a charity which relies so heavily on the generosity of the public, we wanted to give our supporters the chance to see what is achieved through their kind donations.
"The North West Air Ambulance flies seven days a week, 365 days a year throughout five counties in the North West, a region which covers vast terrain, mountain peaks and a complex motorway network.
"This wouldn't be possible without the public's support, and it will be great to give everyone an insight into how our life-saving charity operates."
Comments will be posted on Twitter between 7am and 6.30pm on tweet day, May 4. To follow the tweets visit http://www.twitter.com/NWAirAmbulance.
