Input: The family of a Las Vegas beauty salon manager found dead inside the cryochamber at the business where she worked says the 24-year-old 'died within seconds'. Chelsea Ake, the manager of Rejuvenice in Henderson, Nevada, was found dead inside the salon's cryochamber last Tuesday by distraught employees, NBC reported. The controversial machine is meant to briefly expose the body to freezing temperatures of minus 240 degrees Fahrenheit as a means of 'medical therapy'. Investigators have ruled Ake's death as 'operator error', with preliminary findings suggesting she used the machine after-hours and without assistance and may have suffocated inside. An official cause of death has not been released as medical examiners look into the gases Ake inhaled inside the machine, as well as whether she may have frozen to death.Chelsea Ake, manager of Rejuvenice salon in Nevada, found dead TuesdayMedical examiner told family she 'died within seconds'An official cause of death has not been determinedPreliminary reports suggest Ake may have suffocated from gasesCryotherapy is a controversial 'medical therapy' where the body is briefly exposed to air temperatures at minus 240 degrees FahrenheitMachines are never used for more than three minutes at a time
