Ventilators, When Breathing Is Not Enough For Covid-19 Patients!

Ventilators. A device few had heard of before the pandemic.

This life saving machine is desperately sought after by hospitals around the world. COVID patients with the most severe symptoms require ventilator support to survive and recover. But what is this machine? And what does it actually do?

THE BASICS

Breathing is a simple task, one that we do not think about. When we breathe our chest expands, and air is pulled into our lungs. Here oxygen is exchanged into the blood and transported by the pumping heart throughout the body. In our cells the oxygen is used to release energy from our food, and drive every process and reaction that keeps us alive and functioning.

COVID-19 is a respiratory disease caused by the coronavirus. Its symptoms include a dry cough, fever, feeling tired and more. In most patients the disease is mild. However some suffer from severe disease, causing havoc in their lungs. It can cause viral pneumonia in both of the patients lungs, which reduces the amount of lung able to bring in oxygen to the lung. The patient’s respiratory rate increases, as they struggle to draw in oxygen.

If a person is struggling to breathe on room air doctors can provide them extra oxygen. This is given through a mask they wear on their face. Normal air only has 21% oxygen, but in hospitals it is possible to give air that is 100% oxygen. This means more oxygen reaches the blood, and the patient has to put in less effort to breathe to get the same amount of oxygen to their cells.

In severe cases it can cause widespread inflammation in the lungs, causing fluid to build up and making breathing harder and more laborious. The patient can become tired having to breathe quicker and harder, and this is when doctors look to intensive care specialists and ventilator support.

VENTILATION

If a person is unable to breathe for themselves, it is possible to do this manually or mechanically. Specialists can insert a tube into the mouth of an unconscious patient that enters their windpipe. A bag pump can be attached to this, which a doctor can squeeze to push air into the patient’s lungs. But a person cannot continuously squeeze this bag to keep ventilating someone, as this is time consuming and tiring.

Ventilators are composed of a compressible reservoir or turbine that can push air into the patients lungs. Unlike regular pumps that continuously push air or water, ventilators have to mimic how we breathe. We inspire air in, then expire air out. Ventilators achieve this by pushing in air for a few seconds, inflating the lungs, then releasing the pressure. The natural elasticity of the patients ribs and lungs squeezes the excess air out, mimicking exhalation.

Modern ventilators are very smart, and have many configurable settings. They can be set to deliver defined quantities of air, change the rate of breathing and other advanced settings.

Hospitals regularly use ventilators for patients who are struggling to breathe, patients who are in a coma and have lost the ability to breathe, and also for anaesthetised patients in operating theatres. During the pandemic hospitals are cancelling unnecessary or non-emergency operations, redistributing these ventilators to be used for COVID patients instead.

MAKE MORE VENTS

It is estimated that up to 30% of patients that are admitted to hospital require ventilators. Most hospitals across the world do not have enough ventilators because they have never needed to ventilate so many patients. Governments have recruited the help of manufacturing companies to ramp up production of ventilators. In the UK F1 teams, military aircraft constructors and hoover manufacturers have all taken up the challenge and repurposed their factories.

There have also been innovations to create new ventilator designs that are cheap and easy to produce. This often involves off-the-shelf equipment that is already present in hospitals, and 3D printed parts. Such machines often do not require electricity or circuit board electronics, and can even be powered by the high pressure oxygen flowing from gas canisters or hospital walls.

NEVER A SIMPLE SOLUTION

But as always its not always this simple. Ventilators are complex machines requiring specialist training to function and maintain, as ventilation and respiratory physiology is quite complicated. Ventilators will be of limited use if hospitals do not have enough staff trained to use them safely.

Ventilators are not without risk either. Because they push air into the lung, continuous use, excessive pressures and improper use can cause some damage to the delicate anatomy inside the lung, causing problems in itself. The plastic tube can also be a source of infection. Some hospitals that have had a sharp increase in ventilated patients have encountered problems supplying all their patients with pressurised oxygen. The patient load is overwhelming their infrastructure.

Unfortunately like most things in medicine, ventilators are not a magic cure. Due to the shortage of ventilators not everyone who needs one is able to get it. Most patients who end up needing ventilation are severely ill. The longer a person is on a ventilator the less likely they are to survive. This means that current mortality is rather high.

As more ventilators become available this treatment may become available to those with less severe symptoms, who are more likely to survive especially with this extra help. It is difficult to make these predictions because so many different variables can have an effect. For now we will have to wait and see.

WHAT DOES IT MEAN FOR ME?

The best way to help in these situations is by not catching the virus. This is especially true for those who are elderly, have diabetes, cardiovascular issues or lung diseases. These high-risk patients are more likely to have more serious symptoms, requiring hospitalization. This is why so many countries have enforced lockdown measures. The fewer that are infected, the fewer that need ventilation.

If you do need to leave the house, always follow the following procedures:

- Wash your hands regularly for 20 seconds with soap or alcohol

- Wear a mask outside: This is now official WHO policy

- If you need to cough or sneeze do so into your arm or a tissue

- Only leave the house for essential activities, shopping or to visit the doctor.

Virtual Cooking Class with a Dietitian: Why It’s a Powerful Corporate Wellness Benefit

Corporate wellness programs in India are undergoing a meaningful transformation. What once revolved primarily around annual health checkups and gym memberships is now shifting toward sustainable lifestyle-based interventions. Among these, the virtual cooking class with a dietitian has emerged as one of the most practical and high-impact wellness initiatives for modern workplaces.

Poor dietary habits are a leading contributor to lifestyle-related conditions such as diabetes, obesity, hypertension, and heart disease. According to the Indian Council of Medical Research (ICMR) and the National Family Health Survey (NFHS-5), a significant proportion of India’s working population consumes excess refined carbohydrates, sugar, and unhealthy fats, while falling short on protein, fibre, and essential micronutrients.

For corporate wellness initiatives to create lasting impact, they must move beyond awareness and actively support behaviour change. Dietitian-led virtual cooking classes address this gap by turning nutritional knowledge into daily practice.

Why Nutrition Is a Critical Corporate Wellness Priority

1. Rising lifestyle disease burden among employees

ICMR data highlights the growing health challenge within India’s workforce:

Over 100 million Indians live with diabetes
Nearly one in four adults has hypertension
Obesity rates are rising even among younger professionals

These conditions directly affect productivity, absenteeism, insurance claims, and long-term healthcare costs.

2. Desk-bound and remote work culture

Sedentary routines, irregular meal timings, and reliance on processed or convenience foods have become common in corporate environments, especially with hybrid and remote work models.

3. Knowledge does not translate into action

Many employees are aware of what constitutes healthy eating but struggle to apply this knowledge in everyday cooking. Virtual cooking classes bridge this gap by offering hands-on, real-world guidance.

What Is a Virtual Cooking Class with a Dietitian?

A virtual cooking class with a dietitian is an interactive online session led by a qualified nutrition professional who:

Demonstrates healthy, practical recipes
Explains ingredient choices and substitutions
Teaches portion control and meal balance
Addresses common dietary myths
Answers real-time participant questions

Unlike generic cooking shows or wellness webinars, these sessions are evidence-based and aligned with preventive health goals. They are designed specifically for corporate audiences, ensuring simplicity, cultural relevance, and scalability.

Why Virtual Cooking Classes Work Better Than Traditional Nutrition Talks

1. Practical skill-building

Employees learn how to:

Plan balanced meals
Cook quick, healthy dishes
Reduce excess sugar, salt, and oil
Read food labels with confidence

Skill-based learning leads to stronger habit formation than passive education.

2. Higher engagement and participation

Interactive cooking sessions are:

More engaging than lecture-style talks
Suitable for virtual and hybrid teams
Inclusive across age groups and roles

Participants actively cook, ask questions, and engage rather than passively listening.

3. Cultural relevance

Dietitians tailor recipes to Indian food habits, regional preferences, and household realities, making healthy eating feel practical and sustainable rather than restrictive.

Key Benefits for Employees

Improved daily nutrition

Employees gain confidence in preparing balanced, nourishing meals at home.

Better energy and focus

Stable blood sugar levels and improved nutrient intake support sustained energy and mental clarity during work hours.

Reduced lifestyle disease risk

WHO and Lancet research confirms that dietary improvements significantly reduce the risk of chronic diseases.

Stress reduction

Cooking itself can be therapeutic, contributing positively to mental wellbeing.

Family-wide impact

Healthy habits learned by employees often influence household food choices, extending benefits beyond the workplace.

Why Employers Benefit from Virtual Cooking Classes

1. Reduced absenteeism

Healthier employees tend to experience fewer illness-related absences.

2. Improved productivity

Better nutrition supports cognitive performance, stamina, and focus.

3. Lower long-term healthcare costs

Preventive nutrition initiatives reduce the burden of chronic disease-related claims.

4. Stronger wellness culture

Interactive and practical programs demonstrate genuine employer commitment to employee wellbeing.

5. High return on investment

Compared to large-scale medical interventions, virtual cooking classes are cost-effective, scalable, and easy to implement.

EY–FICCI corporate wellness reports consistently show that nutrition-focused preventive programs deliver higher engagement and long-term impact.

Topics Commonly Covered in Corporate Cooking Classes

Balanced Indian meals
Focus on protein, fibre, and micronutrient adequacy
Quick workday recipes
Healthy meals prepared in under 30 minutes
Disease-preventive diets
Heart-healthy, diabetes-friendly, and weight-conscious cooking
Smart ingredient swaps
Replacing refined grains, excess oil, and added sugar
Portion control techniques
Understanding serving sizes without calorie obsession

Identifying hidden sugar, sodium, and trans fats

How Virtual Cooking Classes Support Preventive Healthcare

Preventive healthcare focuses on addressing risk factors before disease develops, and nutrition plays a central role in this approach.

According to WHO and NITI Aayog:

Dietary modification is among the most cost-effective preventive strategies
Workplace interventions significantly influence adult eating habits

Virtual cooking classes help:

Reinforce preventive screening insights
Support chronic disease management
Improve adherence to dietitian recommendations

Role of AI-Guided Insights in Corporate Nutrition Programs

Modern wellness programs increasingly use data-driven tools to strengthen impact. AI-enabled health insights can:

Identify common nutritional gaps across employee populations
Personalise dietary recommendations
Support dietitians with evidence-based insights
Track long-term wellness outcomes

This ensures cooking sessions are aligned with real employee health needs rather than generic advice.

Why Virtual Delivery Works Best for Corporates

Easy scalability across multiple locations
No physical infrastructure required
Ideal for remote and hybrid teams
Flexible scheduling
Consistent quality delivery

Virtual formats ensure uniform wellness experiences regardless of employee location.

Long-Term Impact on Corporate Wellness

Organisations that consistently implement nutrition-focused wellness initiatives observe:

Higher employee engagement
Improved biometric health indicators
Reduced burnout
Stronger employer branding

Lancet workplace health studies indicate that nutrition-based interventions show measurable benefits within 6–12 months.

Conclusion

A virtual cooking class with a dietitian is more than a wellness activity—it is a powerful preventive health intervention. By equipping employees with practical nutrition skills, these sessions drive meaningful behaviour change, reduce lifestyle disease risk, and support long-term wellbeing. For organisations seeking impactful, scalable, and evidence-based corporate wellness solutions, dietitian-led virtual cooking classes represent a forward-thinking investment in workforce health.
