Pulse oximetry

Pulse oximetry. Pulse oximeter measures The oxygen saturation of haemoglobin in arterial blood – which is a measure of the average amount of oxygen bound to each haemoglobin molecule. Average reading 97-100% Can be placed on finger or ear lobe

Presentation Transcript

  1. Pulse oximetry • Pulse oximeter measures • The oxygen saturation of haemoglobin in arterial blood – which is a measure of the average amount of oxygen bound to each haemoglobin molecule. • Average reading 97-100% • Can be placed on finger or ear lobe • The pulse rate – in beats per minute , averaged over 5-20 seconds

  2. Indications • Monitoring effectiveness of oxygen therapy • Sedation or anesthesia • Haemodynamic instability – AMI, CCf • Respiratory illness • Monitoring during administration of respiratory depressant drugs

  3. Inaccurate readings • May be caused by • A reduction in peripheral pulsatile blood flow produced by peripheral vasoconstriction (hypovolaemia). • Severe hypotension • Cold shivering • CCF • Some cardiac arrhythmias • PVD • Nail varnish (may cause low readings) • Bright fluorescent lighting
