We have had this discussion on mist tents. We have a Pediatric Pulmonologist who will not use the mist tents, he feels that they do not work at all. For RSV he may use continuous albuterol, humidified O2. We use a nasal cannulas they have proven with our patients to be more effective. We can also use cool mist humidifiers in our facility. Maybe for the nurses that can't use the cool mist - could you hook up a humidification system on your air flow meter to flow open in the patient room???? In our facility we always use humidified O2 on children to prevent airway dryness, bleeding etc. This is rule of thumb for any nasal O2 for our children and this has been found to be very effective in reducing dryness, irritation of small airways etc. :)
