Insights
Helmet CPAP is a feasible treatment for infants with acute respiratory failure, showing success in over two-thirds of cases. While generally well-tolerated, caregivers should monitor for pressure sores and be aware of high humidity and noise levels.
Area of Science:
- Pediatric critical care
- Respiratory medicine
- Medical device engineering
Background:
- Acute respiratory failure is a critical condition in infants.
- Continuous Positive Airway Pressure (CPAP) is a common treatment.
- Helmet interfaces offer an alternative to nasal CPAP for infants.
Purpose of the Study:
- To evaluate the feasibility of using helmet CPAP in infants aged 1-12 months with acute respiratory failure.
- To assess the efficacy and tolerance of helmet CPAP in this population.
Main Methods:
- A prospective observational study involving 23 infants (median age 5 months) with acute respiratory failure.
- Helmet CPAP at 6 cm H2O was applied, with observations before and 2 hours after.
- Failure was defined as the need for mechanical ventilation; stabilization or improvement was based on respiratory parameters. Tolerance was assessed via pain scores, skin checks, humidity, and noise levels.
Main Results:
- Helmet CPAP failed in 9% of infants, while 70% showed stability or improvement.
- 96% of infants experienced stable or improved pain and discomfort scores.
- Pressure sores occurred in 13% of infants. High humidity (98%) and noise levels (81 dB-SPL) were recorded.
Conclusions:
- Helmet CPAP is a satisfactory interface for delivering CPAP to young infants in over two-thirds of cases.
- Preventing pressure sores is possible with cushioning.
- Caregivers must manage the high humidity and noise associated with the helmet interface.
Objective:
To report the feasibility of helmet use in infants between 1 and 12 months old with acute respiratory failure.
Design And Setting:
Observations were made before and 2 h after helmet CPAP of 6 cm H(2)O. Failure was defined as recourse to intratracheal ventilation. Patient stabilization or improvement was defined as a variation <10% or a decrease >10% in one of the following: respiratory rate, inspired oxygen fraction, or capillary partial pressure of CO(2). Tolerance was assessed by the pain and discomfort score, the systematic search for pressure sores, and the measurement of helmet humidity and noise level.
Results:
Twenty-three infants with a median age of 5 (2-8) months were included. Helmet CPAP failed in two (9%) patients. Stability or improvement occurred in 16 (70%) patients. The pain and discomfort score was stable or improved in 22 (96%). Pressure sores were found in three (13%) infants. Humidity was 98% (98-99%) and fell to 40% (39-43%) after the humidifier was stopped. The noise level in the helmet was 81 (77-94) dB-SPL.
Conclusions:
The helmet was a satisfactory interface for CPAP delivery in young infants in more than two-thirds of the cases. Pressure sores can be prevented by placing a cushion in the helmet. Caregivers need to take into account the high humidity and noise levels of this interface.

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...
