The low solubility of nitrous oxide in biological tissue and fluid means, in clinical practice, that ENTONOX provide rapid pain relief.
ENTONOX can be administered by inhalation through face or nose masks or mouthpieces as fixed 50:50 mixtures. Gas flow can be controlled by a demand-valve activated by the patient’s inspired breath. The equipment is designed to be portable and easy to use both inside and outside hospital.
ENTONOX is administered by inhalation and therefore are non-invasive, there is no need to insert a cannula or set up an intravenous line. This means that analgesia/sedation with ENTONOX does not need to be administered by a specialist anaesthetist but can be administered by trained staff such as paramedics, nurses and midwives.
