Predictors of Pulse Oximetry Data Failure

Abstract: Pulse oximetry data failure rates based on review of computerized records were markedly greater than those previously reported. Physical status, type of surgery, and intraoperative variables were risk factors for pulse oximetry data failure. Regulations and expectations regarding pulse oximetry monitoring should reflect the limitations of the technology.

“…The oxygen saturation readings become unreliable in these circumstances because conventional pulse oximeter sensors are usually placed at the most peripheral parts of the body such as the finger, where pulsatile flow is most vulnerable [5]. Delay in the estimation of SpO 2 by transmittance pulse oximeters has also been reported [9] in cases of low peripheral perfusion.…”

“…However, the reliability of pulse oximetry when probes are applied to peripheral parts of the body may be compromised in certain patients [1,2], such as those who become hypothermic or hypovolaemic, or have decreased cardiac output [3][4][5]. Such clinical situations occur, for example, after prolonged operations, in particular hypothermic cardiopulmonary bypass surgery.…”

“…The patients in whom failures were found were significantly older, had undergone longer operations and had a higher ASA score than those without failures. Reich et al [14] found a failure rate of 9% in 9203 computerised anaesthesia records (a gap of more than 10 min in recordings). Predictors of failure were ASA groups 3-5, duration of operation, hypothermia and hypotension.…”
