Hypoxemia News and Research

RSS

Hypoxemia (or Hypoxaemia) is generally defined as decreased partial pressure of oxygen in blood, sometimes specifically as less than which, without further specification, would include both concentration of dissolved oxygen and oxygen bound to hemoglobin.

Automated oxygen delivery system improves precision for hospitalized patients

A University of Colorado Anschutz-led clinical trial has found an automated oxygen delivery system helped hospitalized patients spend significantly more time in their target oxygen range compared with standard care, while also reducing exposure to both low and high oxygen levels.

Review explores complex associations between sleep apnea and lung cancer

Obstructive sleep apnea (OSA) is a common sleep disorder characterized by intermittent hypoxia and sleep fragmentation, which may contribute to lung cancer development and progression.

Machine learning model can predict 28-day mortality in sepsis patients

Sepsis is one of the most common and lethal syndromes encountered in intensive care units (ICUs), and acute respiratory failure (ARF) represents one of its most critical complications.

Continuous wearable monitoring improves postoperative oxygen levels and patient safety

Patients continuously monitored after surgery experienced significantly less time with dangerously low oxygen levels compared to those monitored using routine spot checks, a new study from Wake Forest University School of Medicine found.

Pulse oximeters miss hypoxemia more often in people with darker skin, study finds

This large prospective UK study compared five low-cost fingertip pulse oximeters with arterial blood gas measurements and found that readings varied systematically by skin tone and oxygen saturation level. Small average overestimations in darker skin translated into clinically meaningful increases in missed hypoxemia at commonly used SpO2 thresholds.

Understanding the role of m6A methylation in acute lung injury pathogenesis

Acute lung injury (ALI) is a critical clinical condition characterized by diffuse inflammation of the lung parenchyma and intractable hypoxemia, typically caused by factors, such as trauma, pneumonia, shock, and sepsis.

Harvard researchers augment LLM to create expert diagnostic system

Except for one key aspect, the setup is a familiar one in medicine: An expert diagnostician presents a particularly challenging case to a roomful of colleagues, carefully walking them through the patient's symptoms and initial test results.

Huawei smartwatch nearly matches gold-standard sleep test

A study reveals the HUAWEI WATCH GT2 smartwatch accurately tracks sleep stages, yet it falls short in diagnosing sleep disorders compared to PSG.

New insights into bone remodeling process in orthodontic tooth movement under hypoxia

Sustained hypoxia affects orthodontic tooth movement (OTM) by altering osteoclast and osteoblast differentiation, report researchers from Institute of Science Tokyo, Japan.

Predictive tools aim to improve pediatric pneumonia outcomes

Researchers derived pragmatic models that accurately distinguish mild, moderate and severe pneumonia in children, based on evidence from a study performed in 73 Emergency Departments (EDs) in 14 countries through the international Pediatric Emergency Research Network (PERN).

Research challenges traditional oxygen practices in trauma care

When a critically injured patient is admitted to the hospital, how much supplemental oxygen should they receive? New research published this week in JAMA Network Open led by investigators at the University of Colorado School of Medicine suggests it's often less than the current standard.

FDA’s promised rules on pulse oximeters unlikely to end decades of racial bias

The patient was in his 60s, an African American man with emphysema. The oximeter placed on his fingertip registered well above the 88% blood oxygen saturation level that signals an urgent risk of organ failure and death.

Diagnostic errors affecting one in fourteen hospital patients

Harmful diagnostic errors may be occurring in as many as 1 in every 14 (7%) hospital patients - at least those receiving general medical care - suggest the findings of a single center study in the US, published online in the journal BMJ Quality & Safety.

Understanding the role of TIPS in improving renal function amid cirrhosis

Cirrhosis is one of the leading causes of mortality from non-communicable diseases, with complications arising as liver function deteriorates.

No difference in health outcomes between 24-hour and 15-hour oxygen therapy

There were no differences in quality of life, symptoms, hospital admissions or mortality between a group of patients with pulmonary disease and low oxygen levels in the blood that received oxygen therapy at home for 24 hours a day, and a group that received the same therapy for 15 hours a day, according to a study from Lund University in Sweden.
