Inhalation sedation is also referred to colloquially as ‘laughing gas’. This is administered via a nasal cannulae and contains oxygen, (30%), and nitrous oxide gas, (70%), which smells pleasant and is colourless. It allows the patient a happy and light sensation while still being conscious of all events around them and in control of their movements. Nitrous oxide normally takes about 5 minutes to take effect.
