1. Exercise testing involves monitoring a patient's physiological responses like ECG, heart rate, and blood pressure as the level of physical activity is gradually increased in a controlled setting.
2. It is used to evaluate cardiac function and exercise capacity in patients with conditions like heart disease or claudication.
3. Contraindications include recent heart attacks or procedures, unstable angina, and certain arrhythmias or heart failure. Precautions like rest and informed consent are required.
Exercise testing is a non invasive procedure that provides diagnostic and prognostic information and evaluates an individual’s capacity for dynamic exercises
Exercise tolerance testing (also known as exercise testing or exercise stress testing) is used routinely in evaluating patients who present with chest pain, in patients who have chest pain on exertion, and in patients with known ischaemic heart disease.
Cardiac Rehabilitation has been defined as:
Coordinated, multifaceted interventions designed to optimize a cardiac patient’s physical, psychological, and social functioning so that they may, by their own efforts, resume and maintain as normal a place as possible in the community
CHEST MOBILIZATION EXERCISES, COUNTER-ROTATION TECHNIQUE, BUTTERFLY TECHNIQUE, BREATH CONTROL DURING WALKING. These Mobilization Techniques are useful to improve Chest Wall Mobility and Expansion in Patients with Restricted Chest wall movements and also Postoperative patients

This presentation will help physiotherapy students for their theory as well as practical purpose for measuring the exercise tolerance level of the individual.
This presentation includes maximal and sub maximal exercise testing with it's VO2 max formula
This presentation gives brief description of the treadmill test, am-strand cycle ergo-meter test, 6MWT, symptom limited testing, shuttle walk test
Clinical exercise testing is used increasingly in clinical practice for two main reasons (Wasserman)-Its impact in the clinical decision-making process -A growing awareness that resting cardiopulmonary measurements do not provide a reliable estimate of functional capacity. The following are the most popular clinical exercise tests, in order of increasing complexity: (a) 6-minute walk test (6MWT), (b) shuttle walk test, (c) exercise-induced bronchoconstriction (EIB), (d) cardiac stress test, and (e) cardiopulmonary exercise test (CPET). The modality is selected on the basis of clinical question to be addressed and the available equipment.
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.

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. EXERCISE TESTING
• Exercise test are used to assess a patients
ability to tolerate increased physical activity
while electrocardiographic, hemodynamic and
symptomatic responses are monitored in a
controlled environment.
3. INDICATIONS
• physiologic response of post MI and post
revascularization patients to exercise.
• Functional capacity for the purpose of exercise
prescription
• Exercise capacity for the purpose of work classification
and risk stratification.
• The efficacy of medical, surgical or pharmacologic
treatment.
• The presence and severity of arrhythmias
• Preoperative physiologic status.
• Intermittent claudication.
4. CONTRAINDICATION
• A recent change in the resting ECG suggesting
infarction or other acute cardiac event.
• Recent complicated MI.
• Unstable angina.
• Uncontrolled ventricular arrhythmias
• 3rd degree AV block
• Acute congestive HF.
• Severe aortic stenosis
5. CONTI…
• Suspected or known dissecting aneurysm
• Active or suspected myocarditis or
pericarditis.
• Thrombophlebitis
• Recent systemic or pulmonary embolism
• Acute infection
• Significant emotional distress.
6. PRETEST CONSIDERATIONS
• All patient should undergo a complete medical
history and a physical examination to identify
contraindications to exercise testing.
• Detailed verbal and written instruction,
provided to the patient in advance, it include
refrain from ingesting food, alcohol, and
caffeine or using tobacco products within 3
hrs of testing.
7. Conti….
• Patient should be well rested and avoid vigorous
activity the day of the test.
• Clothing should be comfortable and provide
freedom of movement as well as allow access for
electrode and blood pressure cuff placement.
• Properly fitting shoes with rubber soles should be
worn to ensure good traction, particularly if a
treadmill is the mode of testing.
• Provide written and verbal informed consent.
8. PREPARATION FOR ECG
• Sites of ECG electrode placement should be
rubbed with alcohol pad to remove skin oil.
• Place the electrode after applying conducting
gel.
• Mason-Likar limb lead placement is the
standard configuration clinically because it
provides a 12 lead ECG with fewer artifact and
less restriction to movement than the
standard lead placement.
11. 1. Bruce treadmill
• It has 3 min period to allow achievement of a
steady state before workload is increased.
• For Individuals with limited exercise capacity,
Bruce’s protocol can be modified by 2-3 min
warm up stages at 1.7 mph and 0% grade and
1.7mph with 5% grade and speed gradually
increased upto 5.5mph in stages.
• There are total 7 stages in Bruce protocal.
12.
13. • Limitation:-
• Large increase in O2 between stages and
traditional energy cost of running as
compared with walking at stages in excess of
Bruce’s stage III.
14. 2. BALKE TREADMILL
• The Balke protocol and modifications of it,
has been widely used for clinical exercise
testing.
• It uses constant walking speeds (2 or 3mph)
and modest increments in grade (2.5% or 5%)
and it has been used particularly often in
studies assessing angina responses.
15. Conti…
• One modification, developed by the United
States School of Aerospace Medicine(Balke
ware) consist of 5% grade increases every
2min and a constant brisk walking speed of
3.3mph(after an initial warmup of 2mph),
which has been considerd the most efficient
speed for walking.
16. 3. NAUGHTON TREADMILL
• It is a low level test that has become common
for multicenter trials in patients with chronic
heart failure.
• The test begins with 2 min stages at 1 and
2mph and 0%grade, then continually increases
grade in approximately 1 MET increaments at
a constant speed of 2mph for the next 8min.
17. Conti…
• Speed then increase to 3mph with a slight
drop in grade, followed by increases in grade
equivalent to approximately 1 MET.
• This protocol has been used extensively in
patient with congestive heart failure.
18. 4. RAMP TESTING
• It uses a constant and continuous increase in
metabolic demand that replaces the “staging”
used in conventional exercise test.
• The uniform increase in work allows for a
steady rise in cardiopulmonary responses and
permits a more accurate estimation of oxygen
uptake.
19. 5. PHARMACOLOGIC STRESS
TECHNIQUE
• Used for patients Who are unable to do exercise
on a treadmill or cycle ergometer to and
adequate level.
This includes patients having:-
• Orthopedic limitation
• Peripheral vascular disease
• COPD
• Elderly patient with low functional capacity
• DM patient with severe neuropathy
• Patient with neuromuscular
20. Two types of pharmacologic stress agents have
been used:-
• Those that increase coronary blood flow
through coronary vasodilation.
• Those that increase myocardial oxygen
demand by increasing heart rate.
21. 1.increase coronary blood flow
through coronary vasodilation.
• The commonly used coronary vasodilators are
adenosine and dipyridamole (persantine),
where as dobutamine is used to increase
myocardial oxygen demand.
• The vasodilator cause greatly increased
endocardial and epicardial blood flow in
normal coronary arteries but not in stenotic
segment.
22. 2.increase myocardial oxygen demand
by increasing heart rate.
• Dobutamine is used which can create an
imbalance between myocardial oxygen supply
and demand by increasing heart rate and
contractility.
23. • These drugs are administered IV and when
associated with an imaging technique such as
thallium-201 scintigraphy, sestamibi or
echocardiography, can provide important
information about coronary artery stenosis.
24. INTERPRETATION OF EXERCISE
TESTING
Heart rate:-
• Heart rate increases linearly with oxygen
uptake during exercise.
• The inability to appropriately increase heart
rate during exercise has been associated with
the presence of heart disease.
25. Blood pressure:-
• Assess the BP at rest and during exercise.
• BP should be assessed during last minute of
each exercise stage and more frequently if
hypotensive or hypertensive responses are
observed.
• Systolic > 250 mmHg and diastolic >115mmHg
is an indication of termination of exercise.
• A decrease in systolic BP with progressive
exercise suggest that cardiac output is unable
to increase in accordance with the work rate
and is reflection of ischemia.
26. Exercise capacity:-
• Exercise capacity is expressed in METs
(metabolic equivalents).
• MET value can be ascribed to any speed and
grade on a trademill or workload achieved on
a cycle ergometer; therefore exercise capacity
can be compared uniformly between protocol.
• MET refers to a unit of O2 uptake. 1MET is
3.5mlO2/Kg/min of body wt.
27. ECG responses:-
ECG should be repeated every 3 min.
In CAD cases exercise can cause an imbalance
between myocardial O2 demand which can
result in alteration in ST segment.
28. Subjective responses:-
• Angina and dyspnea are the subjective
responses.
• Angina and dyspnea are carefully explained to
patient.
29. ANGINA SCALE:-
• 1+ onset of discomfort.
• 2+ moderate
• 3+ moderately severe
• 4+ severe
30. DYSPNEA SCALE:-
• 1+ mild, noticeable to patient but not to
observer.
• 2+ mild, some difficulty, noticeable to
observer
• 3+ moderate difficulty, but can continue
• 4+ severe difficulty, patient cannot continue.
31. TEST TERMINATION
• Drop in systolic BP>10 mmHg from baseline.
• Moderate to severe angina
• Increasing symptoms of ataxia, dizziness or
syncope.
• Subject desire to stop
• Sustained VT
• ST elevation (1mm) without diagnostic Q wave.
32. RECOVERY PERIOD
• Active recovery consist of walking on the
treadmill at a speed of 1.5 – 2mph.
• An active recovery decreases the risk of
hypotension and dysrhythmias.
• A passive standing recovery should be avoided
because of potential complication of venous
pooling.
• Patient should be monitored for 6-8min after
exercise.
33. • BP, ECG and other symptoms should be
monitored and recorded at 2min intervals .
• Recovery period can be extended to resolve
the symptoms.
34. INSTRUCTIONS
• Avoid long standing, hot showers.
• Patient may experience fatigue and muscle
soreness
• Avoid heavy exertion on same day.
• Any discomfort or pain day after test should
be reported.
Editor's Notes
Intermittent claudication also known as vascular claudication, is an pain, cramping, numbnes, sense of fatigue burning sensation in calf muscle which occur during exercise, walking and is releived by short period of rest. It occur due to poor circulation of blood in the arteries of legs.
