The 911 call made when Lindsay Lohan was found unresponsive in her hotel room recently was classed as "life-threatening" according to a report.

In a recording of the emergency telephone call obtained by TMZ.com, the caller warned the operator that the person the call was made about was at risk of losing their life.

Paramedics rushed to Lohan's side last week at a Ritz-Carlton Hotel in Marina Del Rey, California.

The caller — a male nurse who works for the production company behind Lohan's new movie —called the situation a "Code 3", which is emergency terminology for "life-threat response."

Ambulance protocol for a Code 3 is to use lights and sirens on their vehicle in order to get to the scene as quickly as possible.

Lohan informed someone from the Liz & Dick production team she wasn't feeling well on Friday (15 June) morning — and producers dispatched a doctor to the hotel.

Before arriving, the doctor apparently called the hotel and asked someone to check on Lohan.

When a member of staff to Lohan's door to check on her they determined she was "unresponsive."

Medical experts eventually arrived and decided nothing was wrong. They left without transporting Lohan to the hospital.

After the incident, Lohan tweeted: "Note to self: After working 85 hours in 4 days, and being up all night shooting, be very aware that you might pass out from exhaustion and 7 paramedics might show up at your door."

"Hopefully they're cute. Otherwise it would be a real let down."
