OBJECTIVE: Demonstrate the effectiveness and the good outcome of the patients treated with helium-oxygen (Heliox) mixture. This mixture (Heliox) has been used in patients with airway obstruction, from different ethiologies, who did not respond to a conventional treatment with oxygen. METHODS: Case report of five patients that received Heliox as treatment for airway obstruction. All of them had good results without side effects during the treatment. CONCLUSION: Heliox is a promising treatment for severe airway obstruction with good results in a short period of time, until the final treatment is established.
