Occasionally, the cat's body may use vomiting to clear the intestines of toxins. If the vomit contains excessive amounts of mucus, an inflamed intestine may be the cause. Undigested food in the vomit can be due to food poisoning, anxiety, or simply overeating.
The Schmitt Trigger. The Schmitt trigger is a comparator application which switches the output negative when the input passes upward through a positive reference voltage. It then uses positive feedback of a negative voltage to prevent switching back to the other state until the input passes through a lower threshold voltage, thus stabilizing the switching against rapid triggering by noise as it passes the trigger point.
Trigger Point Injections (20552 and 20553) Always read the full description of a CPT code. For example, 20552 is reported for 1 or 2 muscle groups injected and 20553 is reported for 3 or more muscle groups injected. Example: The patient presented with trigger points in the upper right shoulder and neck region. Injections of lidocaine 2% were injected into three areas of the neck and two areas of the right shoulder into the previously located trigger points. The patient tolerated the procedure well.
