Insights
Helmet noninvasive ventilation (NIV) offers a viable escalation strategy for pediatric COVID-19 patients experiencing high-flow nasal cannula (HFNC) failure. This case demonstrates successful respiratory support when other options are limited.
Area of Science:
- Critical Care Medicine
- Pediatric Infectious Diseases
- Respiratory Therapy
Background:
- Evidence is limited regarding escalating respiratory support from high-flow nasal cannula (HFNC) to noninvasive ventilation (NIV) or mechanical ventilation (MV) in severe pediatric COVID-19.
- A 9-year-old boy with severe COVID-19, Streptococcus pneumoniae, and Pseudomonas aeruginosa coinfection presented with respiratory distress despite biphasic positive airway pressure ventilation.
- A do-not-resuscitate order prevented endotracheal intubation, necessitating alternative respiratory support strategies.
Observation:
- The patient exhibited fever, tachypnea, and frequent desaturation, indicating worsening respiratory status.
- The Respiratory Oxygenation (ROX) index declined significantly after 2 hours of HFNC support, signaling impending failure.
- Helmet-delivered NIV was initiated due to the limitations of other interventions.
Findings:
- Helmet-delivered NIV successfully maintained oxygen saturation (SpO2) above 90%, improving dyspnea and desaturation.
- The ROX index and SpO2/FiO2 ratio can serve as valuable tools for assessing acute respiratory distress syndrome severity when traditional indices are insufficient.
- The patient was transitioned back to HFNC after 6 days and discharged 10 days later, indicating successful recovery.
Implications:
- Helmet-delivered NIV represents a crucial escalation option for pediatric patients with severe COVID-19 when HFNC fails and invasive ventilation is contraindicated.
- This approach can provide effective respiratory support while minimizing aerosolization risk for healthcare professionals.
- Further research into NIV strategies for pediatric respiratory failure is warranted.
Background:
In pediatric patients with severe COVID-19, if the respiratory support provided using high-flow nasal cannula (HFNC) becomes insufficient, no definitive evidence exists to support the escalation to noninvasive ventilation (NIV) or mechanical ventilation (MV). Case Presentation. A 9-year-old boy being treated with face mask-delivered biphasic positive airway pressure ventilation developed fever, tachypnea, and frequent desaturation. The COVID-19 polymerase chain reaction test and urine antigen test for Streptococcus pneumoniae were both positive, and sputum culture yielded Pseudomonas aeruginosa. The do-not-resuscitate order precluded the use of endotracheal intubation. After 2 h of HFNC support, the respiratory rate oxygenation (ROX) index declined from 7.86 to 3.71, indicating impending HFNC failure. A helmet was used to deliver NIV, and SpO2 was maintained at >90%. Dyspnea and desaturation gradually improved, and the patient was switched to HFNC 6 days later and discharged 10 days later.
Conclusion:
In some cases, acute respiratory distress syndrome severity cannot be measured using the oxygenation index or oxygenation saturation index, and the SpO2/FiO2 ratio and ROX index may serve as useful alternatives. Although NIV delivered through a facemask or HFNC is more popular than helmet-delivered NIV, in certain circumstances, it can help escalate respiratory support while providing adequate protection to healthcare professionals.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
