Hemoglobin Rothschild – Unimpaired physical performance and oxygen uptake – A case report with literature review

Respiratory Medicine Case Reports, 2022
Asymptomatic patients with hemoglobin (Hb) variants can be detected by low oxygen levels in pulse oximetry (SpO₂).Depending on the type of Hb variant, low SpO₂ values are either falsely low, with corresponding normal arterial oxygen saturation (SaO₂), or

Anemia That Presented with Desaturation: A Focus on Core Concepts

Case Reports in Pediatrics, 2021
Background. Methemoglobinemia is a potentially life-threatening condition which presents with cyanosis and characteristic “chocolate-coloured blood.” Although a co-oximetry would give a prompt diagnosis, there have been multiple reports of misdiagnosing ...

A 50-year-old woman with severe resting hypoxia not amendable to high-flow oxygen supplementation

European Journal of Case Reports in Internal Medicine
Introduction: Pulse oximetry is a widely used non-invasive method to measure arterial oxygen saturation (SpO2). However, haemoglobinopathies, including rare low-oxygen-affinity variants such as haemoglobin (Hb) Lansing can result in falsely low SpO2 ...

Methemoglobinemia as a Cause of Unexplained Hypoxia in Neurosurgical Patients: A Report of Two Cases

Journal of Neuroanaesthesiology and Critical Care
In methemoglobinemia, ferrous iron in the hemoglobin is oxidized to a ferric state. Hemoglobin in this state cannot carry oxygen resulting in hypoxemia, which manifests as low peripheral oxygen saturation (SpO2).
