In 1955, the Pizza Hut restaurant was first commenced. Its first logo featured its only mascot Pete holding the words Pizza and Hut. 1967â1999. In 1967, the chain began using a new and simplified logo featuring the now-famous red roof design (which is still used albeit in a modified form today).
Oxygen therapy can be delivered using a low flow or high flow system. All high flow systems require humidification. The type of humidification device selected will depend on the oxygen delivery system in use, and the patient's requirements. The humidifier should always be placed at a level below the patient's head.
However, a high flow oxygen (HFO) therapy system can deliver a high flow air/oxygen blend through a nasal cannula or tracheal adapter, providing an alternative to other forms of ventilation. By providing flow rates of up to 60 LPM, high molecular humidity, and precise oxygen delivery, HFO may reduce the need for noninvasive ventilation and intubation in selected patient populations.
