Dapsone‐induced methemoglobinemia—A case report

Clinical Case Reports, 2021
Dapsone therapy is associated with methemoglobinemia. Pulse oximetry is used to indicate adequate oxygen saturations, and co‐oximetry is needed to diagnose low arterial oxygen saturations. Clinicians should aware while prescribing dapsone.

Comparison of Repetitive Cardiac Output Measurements at Rest and End-Exercise by Direct Fick Using Pulse Oximetry vs. Blood Gases in Patients With Pulmonary Hypertension

Frontiers in Medicine, 2021
Background: Exact and simultaneous measurements of mean pulmonary artery pressure (mPAP) and cardiac output (CO) are crucial to calculate pulmonary vascular resistance (PVR), which is essential to define pulmonary hypertension (PH).

Air bubbles and co-oximetry � a pilot study [PDF]

Critical Care, 1997
The pre-analytical error potential of air bubbles contaminating blood gas samples has been well recognized for blood gas tension and pH measurements [1], and is thus considered in present recommendations for blood gas sample handling [2]. The effect of air contamination on the oxygen saturation of haemoglobin (HbO), measured by co-oximetry, has however,

Interference of Methylene Blue with CO-Oximetry of Hemoglobin Derivatives [PDF]

Clinical Chemistry, 1997
Methylene blue (MB) is frequently used as an antidote in treating methemoglobinemia (1) because it facilitates the reducing activity of the NADPH-dependent methemoglobin reductase system in erythrocytes (2). However, MB absorbs strongly between 550 and 700 nm (Fig.

Model for End‐Stage Liver Disease/Pediatric End‐Stage Liver Disease exception policy and outcomes in pediatric patients with hepatopulmonary syndrome requiring liver transplantation

Liver Transplantation, EarlyView., 2022
Abstract Hepatopulmonary syndrome (HPS) is associated with increased waitlist mortality in liver transplantation (LT) candidates. Children with HPS are granted Model for End‐Stage Liver Disease (MELD)/Pediatric End‐Stage Liver Disease (PELD) exception points for waitlist prioritization in the United States based on criterion developed for adults.

The effects of cerebral oximetry in mechanically ventilated newborns: a protocol for the SafeBoosC-IIIv randomised clinical trial

Trials, 2023
Background The SafeBoosC project aims to test the clinical value of non-invasive cerebral oximetry by near-infrared spectroscopy in newborn infants. The purpose is to establish whether cerebral oximetry can be used to save newborn infants’ lives and ...

An acquired acute methemoglobinemia from dietary sources: Case reports and literature review

Emergency Care Journal, 2021
Methemoglobinemia is an alteration of the oxidative state of hemoglobin. When methemoglobin values rise above 10%, the symptoms and signs related to this condition appear, such as cyanosis, respiratory problems, fatigue and headache.

Accident or Arson: Is CO-Oximetry Reliable for Carboxyhemoglobin Measurement Postmortem? [PDF]

Clinical Chemistry, 2010
A 46-year-old woman was found dead in the basement of her home after a fire. External examination of the body showed a wound to the head and soot in the nose and mouth, with soot also found internally in the trachea and bronchi upon autopsy. On questioning by the police, the woman’s husband admitted that he and his wife were having an argument that led
