What is a manual breast pump typically operated by?

• A. Electric current
• B. Hand-squeezing
• C. Vacuum technology
• D. Compression force

Answer: (B)

A manual breast pump is typically operated by hand-squeezing. This means that the caregiver or individual using the pump applies pressure manually to create suction and express milk from the breast. This mechanism is particularly valuable for those who may not have access to an electric pump or prefer a more portable and straightforward option. By squeezing the handle or lever, the user generates the necessary suction to draw milk into the collection container.

Although vacuum technology is utilized in electric breast pumps, a manual pump relies solely on the user's physical effort to create that suction. Similarly, while compression force may play a role in some other types of technology, it is not the primary mechanism in a manual pump. The simplicity of hand-squeezing makes this type of breast pump user-friendly and effective for various situations, such as nursing mothers seeking to express milk on the go.
