True or false A) One disadvantage of the catheter tip pressure sensor is that it is more expensive than others and can break after just a few uses, further increasing your cost per use. …B) Several different types of sensing elements can be used and include: strain gauges, linear variable differential transformers, variable inductance, variable capacitance, optoelectronic, piezoelectric, and semiconductor devices. ….C) Rare are modern hospitals that have adopted disposable pressure sensors, since despite being cheap, the risk of cross-contamination of the patient is not reduced. …D) The most common clinical method for directly measuring pressure is to couple vascular pressure to an external sensor via a fluid-filled catheter. …………..
