Frequently Asked Questions

What is a bubble humidifier used for in oxygen therapy?

A bubble humidifier adds moisture to dry medical oxygen before it is delivered to the patient. This helps prevent drying and irritation of the nasal passages, throat, and airways during supplemental oxygen therapy — particularly important for patients receiving oxygen at flow rates above 4 L/min or for extended periods.

Is this product single-use?

Yes. Dynarex Resp-O2™ Prefilled Bubble Humidifiers are single-use disposable to prevent cross-contamination between patients and maintain sterility of the water supply.

What is the difference between this product and the 12/CS prefilled sterile water bottles?

This product is a prefilled bubble humidifier (350 mL) designed to connect directly to oxygen flowmeters for continuous humidification. The 12/CS prefilled sterile water bottles are smaller-volume units designed for nebulizer dilution and general inhalation device use.
