Pulse oximeter ingestion in a psychotic patient.

Psychotic conditions such as schizophrenia, bipolar disorder, major depressive disorder, and polysusbstance abuse are risk factors for foreign body ingestion. A foreign body can include sharp objects that lead to serious complications. In this case report, we present a patient with a history of psychosis who ingested a pulse oximeter in a suicidal attempt. The pulse oximeter passed uneventfully with no interventions needed, and was followed by a serial of abdominal imaging.
