<p>Method of optimisation of the positioning of an electrode for monitoring ECG or breathing in a patient, such as a neonatal child comprising measuring the circumference of the head of the patient and applying the formula: y = x - b where y = the optimal position to place the proximal electrode within the oesophagus, expressed as the distance of the proximal electrode from the nares or lips of the neonatal child, x = the circumference of the head of the neonatal child in centimetres, b = a value between 18 and 22. Oesophageal feeding tubes comprising position indicators are also provided.</p> |
