Case Report: Ventilatory Failure from HMEF Saturation in an Intubated Infant

A 13-month-old boy developed hypercapnia and ventilatory failure after a retained heat and moisture exchanger filter (HMEF) was exposed to active heated humidification. The case report details the clinical presentation, treatment, and resolution following HMEF removal. Author Hengjing Zou published this CC-BY-4.0 licensed document on figshare in May 2026.

Use Cases

• Analyzing risk factors for ventilatory failure in pediatric anesthesia based on the described case of HMEF dead space and saturation.
• Training clinical decision support models on rare adverse event scenarios based on the detailed timeline of symptoms and interventions.
• Studying the interaction between passive and active humidification systems in ventilator circuits based on the described mechanism of circuit occlusion.

Strengths

• The report provides specific clinical measurements, including peak inspiratory pressure (40 cmH2O), tidal volume (90 mL to 50 mL), and PaCO2 (81.5 mmHg to 119.5 mmHg).
• It includes a detailed narrative of the clinical course, interventions, and outcome, offering a complete case study.

Limitations

• The dataset is a single case report (18.5 KB DOCX file), representing an n=1 sample with limited generalizability.
• Row count and column-level documentation are absent; data structure must be inferred from the narrative text.
• Last updated 2026-05-13 05:51:26; freshness should be verified.
