Excessive breathing creates low levels of carbon dioxide in your blood. This causes many of the symptoms of hyperventilation. Feeling very anxious or having a panic attack are the usual reasons that you may hyperventilate.
Ladyfingers (often called savoiardi and in British English sponge fingers) are low density, dry, egg-based and sweet sponge biscuits roughly shaped like a large finger. They are a principal ingredient in many dessert recipes, such as trifles, charlottes, as fruit or chocolate gateau linings and for tiramisu.
Fill a large pastry bag with a 3/4-inch plain tube with the mixture. Pipe fingers about 4 1/2-inches in length on to the baking sheet, using the lines as a guide. Dust the ladyfingers with powdered sugar. Bake until for 15 to 18 minutes, or until just firm on the outside and soft in the center.
