Arrange these principal stages of vacuum extraction in order.
Answer
Apply the cup at the flexion point, Create negative pressure, Apply traction with contractions and maternal effort, Reduce the vacuum gradually after delivery of the head
Explanation
The procedure proceeds from cup placement to creation of suction, followed by traction coordinated with contractions and maternal expulsive efforts. After the head is delivered, the vacuum is reduced gradually using the release mechanism. Correct sequencing supports controlled application and avoids unnecessary abrupt release.\n\n**Key takeaway:** Place, establish suction, apply coordinated traction, then release gradually.\n\n**Glossary:** **Negative pressure**: Pressure below atmospheric pressure used to attach the cup; **traction**: A controlled pulling force; **chignon**: Temporary swelling at the vacuum cup site, which the slides state resolves over about 48 hours.
