The 37 pages that link to Pulse oximetry, each with the reason it gives.

• Carbon monoxideCompared with: Standard devices may mistake carboxyhemoglobin for oxygenated hemoglobin and give misleading readings.

• Carbon monoxide poisoningRelated: Standard devices can mistake carboxyhemoglobin for oxyhemoglobin and give falsely reassuring readings.

• Respiratory depressionRelated: It helps monitor oxygenation, though it may not reveal carbon dioxide retention.

• HypoxiaRelated: It helps assess oxygenation, but cannot directly measure oxygen levels in tissues.

• HypoxemiaRelated: It provides a rapid estimate of oxygen saturation, though it does not measure oxygen tension.

• SedationRelated: It tracks oxygenation during sedation but may not detect early hypoventilation.

• Medical deviceBroader topic: The pulse oximeter illustrates optical measurement used for physiological monitoring.

• Airway managementRelated: It helps track oxygenation during airway interventions but does not measure ventilation directly.

• Respiratory systemRelated: It provides a quick estimate of oxygenation, one outcome of lung gas exchange.

• MethemoglobinemiaRelated: Methemoglobin distorts its usual two-wavelength readings, often driving the displayed saturation toward 85%.

• PolysomnographyRelated: Oxygen levels can fall during breathing interruptions recorded in the study.

• Oxygen therapyRelated: It helps monitor oxygen saturation while supplemental oxygen is given.

• Arterial blood gas testCompared with: It offers continuous oxygen-saturation monitoring but does not measure pH or carbon dioxide.

• Respiratory failureRelated: It monitors oxygen saturation but does not measure carbon dioxide.

• Oxygen–hemoglobin dissociation curveRelated: The curve helps relate a saturation estimate to blood oxygen partial pressure, with limitations.

• Pulmonary function testingCompared with: It tracks oxygen saturation but does not measure airflow, lung volume, or carbon dioxide.

• ResuscitationRelated: It can help assess oxygenation, though it does not establish whether circulation is adequate.

• TelemetryRelated: Pulse oximeters can provide bodily measurements for remote transmission.

• CapnographyCompared with: It tracks oxygenation, whereas capnography tracks exhaled carbon dioxide and ventilation.

• Vital signsRelated: It can add oxygen saturation and pulse rate to routine observations.

• CyanosisRelated: It helps assess oxygenation, though some abnormal hemoglobins can distort its reading.

• Near-infrared spectroscopyCompared with: It estimates arterial saturation, whereas NIRS samples a mixture of arterial, venous, and capillary tissue blood.

• Supplemental oxygen in mountaineeringRelated: Readings can track oxygenation, though altitude and cold complicate interpretation.

• WaveformRelated: Its photoplethysmographic waveform tracks pulse-related changes in blood volume.

• Cerebral hypoxiaRelated: It helps detect low blood oxygen, though it does not directly measure brain oxygenation.

• HypopneaRelated: Overnight oxygen readings help identify desaturation associated with hypopneas.

• PulseRelated: Its optical sensor detects pulsatile changes in blood volume.

• Respiratory rateRelated: It complements rate measurement by assessing oxygenation, which rate alone cannot establish.

• Tetralogy of FallotRelated: It helps detect and monitor low oxygen levels associated with cyanotic spells.

• AnoxemiaRelated: It provides rapid monitoring of oxygen saturation during suspected blood oxygen deficiency.

• Respiratory diseaseRelated: It offers a quick estimate of oxygenation when respiratory illness is suspected.

• Tricuspid atresiaRelated: It can detect the low oxygen levels common in affected newborns.

• Central hypoventilation syndromeRelated: It helps monitor oxygenation, but does not directly measure carbon dioxide retention.

• Circulatory and Respiratory Physiological PhenomenaRelated: It provides a rapid estimate of blood oxygenation during respiratory and circulatory assessment.

• Respiratory tract infectionRelated: It can detect impaired oxygenation in serious lower respiratory infections.

• Shortness of breathRelated: It checks oxygenation, while a normal result does not rule out severe subjective dyspnea.

• Transposition of the Great VesselsRelated: Low oxygen saturation can prompt evaluation for this cyanotic heart defect.
