DCM

DCM is an acronym with several unrelated meanings across science, medicine, engineering, and media. This article outlines the main uses.

Dichloromethane, also known as methylene chloride (DCM), is an organochlorine solvent with the formula CH2Cl2. It is a volatile, dense liquid used in chemical synthesis, paint stripping, and metal cleaning. Exposure can affect the nervous system, with dizziness and headaches among symptoms. Because of toxicity concerns, it is regulated in many jurisdictions and requires proper ventilation and protective equipment. Waste disposal follows hazardous-waste guidelines.

Dilated cardiomyopathy (DCM) is a heart-muscle disease characterized by dilation of the ventricles and impaired contraction. It can be idiopathic or genetic and may be associated with infections, toxins, or alcohol use. Symptoms include dyspnea, fatigue, and edema. Diagnosis relies on imaging such as echocardiography or cardiac MRI, along with other tests. Treatment follows guideline-directed medical therapy and may involve medications, lifestyle adjustments, and, in advanced cases, device therapy or heart transplantation.

Direct current motor (DCM) is an electric motor powered by direct current. It offers straightforward speed control and high starting torque but relies on a commutator and brushes, which wear over time. DCMs are common in hobby electronics, robotics, and applications requiring precise speed control, though brushless DC motors are increasingly favored in newer designs.

Digital Cinema Media (DCM) is a cinema advertising company operating in the United Kingdom. It provides advertising across digital screens in cinemas, enabling brands to reach audiences during film-going experiences. DCM coordinates campaigns across its network and integrates with broader media planning.
