Bronchial asthma (or asthma) is a lung disease. Your airways get narrow and swollen and are blocked by excess mucus. Medications can treat these symptoms.
Asthma is a chronic disease involving the airways in the lungs.
Asthma is a condition in which your airways narrow and swell and may produce extra mucus.
This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out, and shortness of breath.

Clinical manifestation
Diagnostic evaluation
Bronchoprovocation Testing: Testing that is done to identify inhaled allergens; mucous membranes are directly exposed to suspected allergen in increasing amounts. Skin Testing: Done to identify specific allergens. Exercise Challenges: Exercise is used to identify the occurrence of exercise-induced bronchospasm. Radio allergosorbent Test: Blood test used to identify a specific allergen. Chest Radiograph: May show hyper expansion of the airways.
Managemnet
Goal- Promote bronchodilationn Reduce inflammation Remove secretions Prevent ongoing symptoms Prevent asthma attack Maintain normal lung function Avoid triggers
Pharmacological therapy 1. Long term control medication- Inhaled corticosteroid Leukotriene modifiers Long acting beta agonist Methylxanthines Combine inhaler
2 Quick relief medication Short acting beta agonist Anticholinergic Oral or I/V corticosteroid
3 Bronchial thermoplasty- Form severe asthma that does not respond to medication
Non- pharmacological
Oxygen therapy Postural drainage & chest physiotherapy Coughing & deep breathing exercise Avoidance of allergen relaxation technique acupuncture
Prevention
Patients with recurrent asthma should undergo tests to identify the substances that precipitate the symptoms. Possible causes are dust, dust mites, roaches, certain types of cloth, pets, horses, detergents, soaps, certain foods, molds, and pol- lens. If the attacks are seasonal, pollens can be strongly sus- pected. Patients are instructed to avoid the causative agents whenever possible.
Complications Complications of asthma may include status asthmaticus, respiratory failure, pneumonia, and atelectasis. Airway obstruction, particularly during acute asthmatic episodes, often results in hypoxemia, requiring the administration of oxygen and the monitoring of pulse oximetry and arterial blood gases. Fluids are administered, because people with asthma are frequently dehydrated from diaphoresis and in- sensible fluid loss with hyperventilation.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.

stimuli.
http://www.merriam-webster.com/dictionary/asthma
7. When cough is the only asthma symptom, this is known as
cough variant asthma (CVA)
8. A common respiratory condition that results from exposures in the
workplace
Examples of the occupations and the potential irritants include:
a) Dental hygienists: latex
b) Bakers: flour
c) Welders and metal workers: metals: metals (nickel, platinum and
chromic acid)
d) Plastic manufacturer.
e) Farmers and veterinarians: animal proteins
f) Carpenters: wood dust
9. A type of asthma triggered by exercise or physical exertion.
11. The chances of having asthma symptoms are much higher
during sleep because asthma is powerfully influenced by the
sleep pattern.
Causes : Exposure to allergens, cooling of the airways, heart
burn at night .
12. Genetic factors
Environmental factors
a) House dust mites
b) Exposure to tobacco smoke.
c) Predisposed to animals, pollens and dust.
Dietary changes – junk food and fast food .
13. Lack of exercise - Less stretching of the airways

PEFR is used to assess the severity of wheezing in those who have
asthma. PEFR measures how quickly a person can exhale air from the
lungs
Peak expiratory flow rate (PEFR)
22. It measures how much air you can exhale.
FEV1(force expiratory volume) > 80% = normal
Confirms the presence of airway obstruction and measure the
degree of lung function impairment.
Monitor your response to asthma medications

28. Antiinflammatory drugs
◦ Corticosteroids (e.g., beclomethasone, budesonide)
Suppress inflammatory response
Inhaled form is used in long-term control
Systemic form to control exacerbations and
manage persistent asthma
29. Asthma nebulizer
Changes asthma medications from a liquid
to a mist, so that they can be more easily
inhaled into the lungs.
30. Impaired breathing pattern
Ineffective airway clearence
Risk for infection
Activity intolerence
Imbalanced nutrition
Fear and anxiety
Sleep pattern disturbance
Knowledge deficit
