Vacuum delivery is a device used to assist delivery by creating negative pressure between a suction cup and the fetal scalp. It has a suction cup, vacuum generator, and traction tubing. There are different cup types, including Malmstrom, Bird, and soft silicone cups. Vacuum delivery is indicated for maternal or fetal distress in the second stage of labor or prolonged second stage. Proper technique involves assessing fetal position, applying the cup to the flexion point, gradually increasing negative pressure, and applying traction in sync with contractions along the curve of Carus. Complications can include cephalhematoma and injuries for the baby or soft tissue injuries for the mother.
When fetal head is delivered, but shoulders are stuck and cannot be delivered it is known as shoulder dystocia.
The anterior shoulder becomes trapped behind on the symphysis pubis, whilst the posterior shoulder may be in the hollow of the sacrum or high above the sacral promontory.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Description
• It is an instrumental device designed to assist
delivery by creating a vacuum (negative
pressure) between itself and the fetal scalp.
3. Parts
• Suction cup of variable sizes (30, 40, 50, 60
mm). It is either metallic, or soft (made of
silicone.)
• Vacuum generator.
• Traction tubing.
4. Types
• Malmstrom cup
– A metal cup to its centre attached a metal chain
passed through the rubber tube. The other end of the
chain is attached to a handle for traction.
• Bird’s cup
– The suction rubber tube is attached to the periphery
of the cup while the handle of traction is attached by
a separate short metal chain to the centre of the cup.
• Soft cup
– It is a bell-shaped 6.5 cm diameter soft cup which is
made of a firm but supple silastic material.
9. Soft Cup
• Advantage: It produces symmetric, less
cosmetically alarming caput succedaneum and
less scalp abrasions.
• Disadvantage: It slips more than the metal cup
but with less scalp injuries.
10. Indications
• Maternal distress in 2nd stage of labour.
• Fetal distress in 2nd stage of labour.
• Prolonged 2nd stage.
• To shorten the 2nd stage in VBAC.
• For prophylactic use in mothers with
cardiovascular, respiratory, cerebrovascular
disorders.
12. Prerequisites
• Bladder must be emptied
• Cervix fully dilated
• No evidence of CPD
• Vertex presentation and not above the station
of +2
• Membranes must be ruptured
13. Technique
• APPLICATION
– Station of the head and its position is assessed
– Instrument is checked to be in working condition
before application
– Selection of the cup is important
– The cup is introduced after retraction of perineum
with two fingers of the other hand
14. – The center of the cup
should be on the flexion
point of the head, which is
a point located on the
sagittal suture, 3cm in front
of posterior fontanelle
– Traction at this point results
in maximum flexion (flexing
median application)
16. Technique
• NEGATIVE PRESSURE
– The vacuum is created gradually after ensuring that no
soft tissue is included in the cup.
– Once the pressure reaches 0.2kg/cm2, it is rechecked
for inclusion of the soft tissue in the cup.
– The negative pressure is then gradually increased to a
maximum of 0.8kg/cm2 to create a chignon (artificial
caput)
– Following this the traction is applied
17. • Traction should be synchronous with uterine contraction
• Direction of pull should follow curve of Carus
• Traction should be at right angle to the cup
Principles During Traction
18. Principles During Traction
• Counter pressure should
be applied with the left
hand (thumb on the cup,
index finger on the scalp)
to prevent slipping
• Descent should occur
with each pull
• Delivery should occur
within 3 pulls over a
period of 15 minutes
19. Principles During Traction
• If the cup slips, reevaluate the station and
position of the head and reassess the pelvis
• Reapply only when there is no problem
• If it slips again or descent is not satisfactory, the
procedure should be abandoned
• As soon as baby is delivered, the vacuum
pressure is reduced, and cup is detached
• Delivery is completed in the normal way
24. Comparison
Forceps Delivery Vacuum Delivery
Does not require maternal effort Require some maternal effort as need to
synchronize with uterine contraction
Equipment less complex Less expertise required
Less incidences of cephalhematoma More incidences of cephalhematoma
Can be used in preterm Cannot be used in preterm
Can be used in non-cephalic
presentations
Can be used in partially-rotated head. Not
used in non-cephalic presentations.
Less injuries to infant, higher morbidity
for mother
Less maternal injuries, higher morbidity
for infant
Need for anesthesia/analgesia No need for anesthesia
Takes less time in fetal distress, quicker
delivery
Higher failure rate
