Are intrapartum fetal monitoring guidelines fit for purpose?
One of the core assumptions that must be true in order for CTG monitoring to reduce perinatal harm from low oxygen levels, is that there must be recognisable CTG patterns that clinicians can consistently identify, and that are strongly associated with low oxygen levels in the fetus. Measuring oxygenation directly is tricky so alternative measures are generally used instead. Typically, acidosis is measured as low oxygen levels switch metabolic processes […]
