Hi Thanks for writing to health care magic Tremors in the resting state are characteristic of parkinson s disease. These tremors occur in the extremities and are associated with rigidity and slowness. Sometimes toxicity due to Co2 can precipitate parkinsonian symptoms. The treatment for CO2 intoxication includes giving O2. Treatment of tremors for parkinsonism involves giving levodopa and anticholinergic drugs. But in ur husband the tremor is not typical of a parkinson s type. The other causes of tremor include: essential tremor, hypoglycaemia, liver disease, wilson s disease, asterexis, myoclonus, epilepsia partialis continua, drug abuse, cerebellar disease, demyelinating disease etc should be considered. Management depends on the cause Hope this helps u Thanks and regards
