A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

15. The IAB Counter pulsation system
A flexible catheter -2 lumen
• first - for distal aspiration/flushing or pressure monitoring
• second - for the periodic delivery and removal of helium gas to a
closed balloon.
16.
17. HEMODYNAMIC EFFECTS — Inflation and deflation of the balloon
• Blood is displaced to the proximal aorta by inflation during
• diastole.
• Aortic volume ( afterload) is reduced during systole through
a
vacuum effect created by rapid balloon deflation
18. Expected changes with IABP support in hemodynamic profile in
patients with Cardiogenic shock
- Decrease in SBP by 20 %
- Increase in aortic Diastolic Press. by 30 % ( raise coronary blood flow)
- Increase in MAP
- Reduction of the HR by 20%
-Decrease in the mean PCWP by 20 %
- Elevation in the COP by 20%
19.
20. IABP catheter:
10-20 cm long polyurethane bladder
25cc to 50cc capacity
Optimal 85% of aorta occluded (not 100%)
The shaft of the balloon catheter contains 2 lumens:
- one allows for gas exchange from console to
balloon
- second lumen
- for catheter delivery over a guide wire
- for monitoring of central aortic pressure
after installation.
26. Connect ECG
Set up pressure lines
Femoral access – followed by insertion of the supplied
sheath(7.5 F)
0.030 inch supplied J-shaped guide wire to the level of the
aortic arch (LAO view)
STEP BY STEP- IABP insertion
28. Take the entire catheter and T handle as one unit
(DO NOT disconnect one-way
valve when removing the
extracorporeal tubing from the
tray.)
Pull out the T- handle only as shown
29. ●
• Remove stylet/aspirate/Flush
●
• Insert the balloon only over the guide wire
●
• Hold the catheter close to skin insertion point
●
• Advance in small steps of 1 to 2 cm at a time and
●
stop if any resistance.
●
• The IABP should advance freely
Inserting the Balloon catheter
- Many vascular complications occur during insertion itself
- Resistance during insertion either indicates PVOD, or dissection
- Kinking of IABP » improper inflation/deflation
30. - The end of the balloon should be just distal (1-2 cm) to the takeoff of the
left subclavian artery
- Position should be confirmed by fluoroscopy or chest x-ray
Positioning
31. Connecting to console:
- Connect helium gas tube to the console via a long extender
- Open helium tank.
- The central lumen of the catheter is flushed and connected to
pressure
tubing with 3 way and then to a pressure transducer to allow for
monitoring of central aortic pressure.
- Zero the transducer
Initial set-up:
- Once connected properly the console would show ECG and pressure
waveforms.
- Check Basal mean pressure
- Make sure the setting is at “auto”
- Usually IABP started at 1:1 or 1:2 augmentation
- Usually Augmentation is kept at maxim
32.
33. Trigger modes
Trigger :
- Event the pump uses to identify the onset of cardiac cycle (systole)
- Pump must have consistent trigger in order to provide patient assist
- If selected trigger not detected, counter pulsation will interrupted
1.ECG
- uses the slope of QR segment to detect triggering point
2. AP(Arterial pressure wave)
- Systolic upstroke of the arterial pressure wave form is the trigger
3. IN(Internal trigger)
34. ECG signal – most common
• Inflation
- middle of T wave
• Deflation
– peak of R wave
• Pacer (v/a)
• Arterial waveform
• An intrinsic pump rate
(VF, CPB)
35. Auto Operation Mode

Automatic and continuous inflation
and deflation timing management
- User has ability to fine-tune
deflation timing
Automatic management of irregular
rhythms
Semi-Auto Operation Mode
Operator selects most appropriate
lead and trigger source
Initial settings

Is Deflation slope ok
48.
49. Late Inflation
Inflation of the IAB markedly after closure of the aortic valve.
Waveform Characteristics:
• Inflation of IAB after the dicrotic notch.
• Absence of sharp V.
●
Sub optimal diastolic augmentation
51. Late Deflation
Late deflation of the IAB during the diastolic phase.
Waveform Characteristics:
• Assisted aortic end diastolic pressure may be equal to the
unassisted aortic end diastolic pressure.
• Rate of rise of assisted systole is prolonged.
• Diastolic augmentation may appear widened
54. Variation in balloon pressure wave forms
Increased duration of
plateau due to longer
diastolic phase
Decreased duration
of plateau due to
shortened diastolic
phase
55. Variation in balloon pressure wave forms
Varying R-R intervals
result in irregular
plateau durations
56. Variation in balloon pressure wave forms
Increased height
or amplitude of
the waveform
Decreased height
or amplitude of the
waveform
57. Variation in balloon pressure wave forms
Gas leak
Leak in the closed system causing the
balloon pressure waveform to fall below
zero baseline..
- due to a loose connection
- a leak in the IAB catheter
- H2O condensation in the external tubing
- a patient who is tachycardiac and febrile which causes increased gas
diffusion through the IAB membrane
58. Catheter Kink
Rounded balloon pressure waveform
- Loss of plateau resulting from a kink or
obstruction of shuttle gas
- Kink in the catheter tubing
- Improper IAB catheter position
- Sheath not being pulled back to allow
inflation of the IAB
- IAB is too large for the aorta
- IAB is not fully unwrapped
- H2O condensation in the external tubing
60. Patient Management During IABP support
Anticoagulation-- maintain apTT at 50 to 70 seconds
CXR daily – to R/O IAB migration
Check lower limb pulses - 2 hourly.
- If not palpable » ? - vascular obstruction
- thrombus, embolus, or dissection
(urgent surgical consultation)
Prophylactic antibiotics --??
Hip flexion is restricted, and the head of the bed should not be
elevated beyond 30°.
61. Never leave in standby by mode for more than 20 minutes >
thrombus formation
Daily
– Haemoglobin (risk of bleeding or haemolysis)
– Platelet count (risk of thrombocytopenia)
– Renal function (risk of acute kidney injury secondary to distal
migration of IABP catheter)
Wean off the IABP as early as possible as longer duration is associated
with higher incidence of limb complications
Patient Management During IABP support
62.
63. Weaning of IABP
Timing of weaning:
- Patient should be stable for 12 – 24 hours
- Decrease inotropic support
- Decrease pump ratio
– From 1:1 to 1:2 or 1:3
- Decrease augmentation
- Monitor patient closely
– If patient becomes unstable, weaning should be
immediately discontinued
64. IABP Removal
- Discontinue heparin six hours prior to removal
- Disconnect the IAB catheter from the IAB pump
- Patient blood pressure will collapse the balloon membrane for withdrawal
- Withdraw the IAB catheter through the introducer sheath until resistance
is met.
- NEVER attempt to withdraw the balloon membrane through the
introducer sheath.
- Remove the IAB catheter and the introducer sheath as a unit
- Check for adequacy of limb perfusion after hemostasis is achieved.
