**3. Conclusion**

The use of POCUS in the ED has grown over the past two decades and has evolved from basic uses (that are discussed in this chapter) to include more advanced applications. Despite the limitation of POCUS, it has numerous advantages that justify its use. The advantages include, but are not limited to, improving the diagnostic accuracy for certain complaints, decreasing ED length-ofstay, improving patient satisfaction, improving procedure success rate, and decreasing procedure complication rates. Any EP practicing in this day and age in a center with POCUS availability has little excuse to justify not utilizing this powerful resource for the best of their patients.
