rhinopharyngeal retrograde clearance (RRC) isolated: First patient sits in a chair. Second: patient inhales air deeply and exhales making noise and vibration in the upper airway to facilitate swalling. Third patients finishes with another deep inhalation. This technique is new, simple to use and with no cost. No need of any material or equipment.
retrograde rhinopharyngeal retrograde clearance combined with saline instillation (RRC+S): patient sits in a chair and inhaled air and make noise and vibrate the upper airway at the same instills saline into the nare to facilitate nose washing and swalling. This technique is new, simple to use and with low cost (only saline).
