Abstract
High frequency medical breathing apparatus is provided, which delivers efficiently controlled high frequency air pulses to a catheter, and which is of relatively low cost and is energized by pressured air that is commonly available in a hospital environment. The apparatus includes a large flexible bag with entrance and exit openings, walls forming a sealed chamber around the bag, and a source that applies pressure pulses to the chamber to partially compress the bag at each pulse so as to deliver air through the exit end of the bag and a check valve, and into a catheter that leads to a patient's lungs.
