A copper kettle has a dedicated flow meter which is dialed up separately.

This is mixed with the FGF which is separate; thus giving 500mL of vapour, 500mL of gas which went into the copper kettle, 2L of oxygen and 2L of nitrous.

Not all patients can have a biopsy, these include children less than 10-12yrs (30kgs), pregnant women, and patients on prolonged steroid therapy. If the proband cannot be tested, eg a young child or deceased, then the nearest most appropriate relative is tested. In the case of a young child this would be the parents. Once the proband has been confirmed as MH susceptible, a blood sample taken at the time of the biopsy will be screened to see if they carry one of the genetic mutations that can be used to test for MH. At present only around 60% of families carry one of these mutations of which there are currently 27
