Breathing is an important process in life. The body uses the lungs for oxygen delivery into its organs via respiration; every organ relies on this source of energy. If the lungs are unable to provide oxygen for some reason or if they cannot eliminate carbon dioxide effectively, this can lead to respiratory failure.
Respiratory disorders are on the rise due to pollution, cigarette smoke, infection, and chronic lung conditions. Early recognition of common causes of respiratory failure and symptoms of lung disease is crucial for treatment and improved recovery.
What is Respiratory Failure?
When your lungs cannot provide enough oxygen and remove enough carbon dioxide from the blood, you will experience respiratory failure.
The respiratory system’s primary function is to bring oxygen into our bodies and remove carbon dioxide through our lungs. Any damage that is sustained to your lung tissue, from your airways or to your breathing muscles, will hinder the normal functioning of the respiratory system, resulting in respiratory failure.
Acute respiratory failure:
Acute respiratory failure occurs when symptoms arise very rapidly, and treatment is needed instantly.
Chronic respiratory failure:
This failure is a gradual condition, normally arising with long-term lung disease or a long-term respiratory condition.
Types of Respiratory Failure
There are two main types of respiratory failure as identified by doctors:
1. Hypoxemic Respiratory Failure
This respiratory failure can occur in a variety of conditions, where blood oxygen levels drop dangerously low. Common causes can include pneumonia, extreme COVID-19 infection, ARDS, or pulmonary oedema.
2. Hypercapnic Respiratory Failure
This involves the increase of carbon dioxide levels in the blood, as the lungs struggle to clear the body and are unable to push it out as breath. Chronic obstructive pulmonary disease (COPD) is a common condition that contributes to this type of failure.
Both Hypoxemic and Hypercapnic failure may be present in a patient at the same time.
How the Respiratory System Works
The respiratory system consists of a series of organs, including the lungs, airways, and diaphragm. When we take in a breath, air enters our lungs and is then transferred to our bloodstream. Our body gets rid of carbon dioxide from our body through a breath of air leaving our body. The health of our lungs is crucial for good overall lung health.
Respiratory Failure Causes:
1. Chronic Lung Disease
The risk of respiratory failure is highest in people with chronic lung disease. Diseases include COPD, asthma, pulmonary fibrosis, bronchiectasis, and interstitial lung disease. They affect oxygen transport by damaging the lungs.
2. Severe Pneumonia
Pneumonia causes inflammation of the lungs, which can block oxygen supply, and if severe, it can cause respiratory failure.
3. COVID-19 and Viral Infections
COVID-19 and viral infections, such as influenza and RSV, damage your lungs significantly, which can cause respiratory failure and affect oxygen supply.
4. Smoking
Smoking is damaging the lungs through smoke and increases the risk of developing diseases such as emphysema, COPD, and other forms of respiratory failure.
5. Heart Failure
If you suffer from heart failure disease your lungs may fill with fluid, which may reduce oxygen levels and cause respiratory failure.
6. Drug Overdose
Alcohol, narcotics, or any other form of medication will slow your breathing rate, causing your oxygen levels to drop, which may lead to respiratory failure.
7. Neuromuscular Disorders
A disease that has attacked the brain, nerves, or muscles will severely impair the workings of your breathing muscles, potentially causing respiratory failure.
Lung Disease Symptoms
Many people ignore lung disease, considering a mild cough a normal illness, yet if left undiagnosed they can lead to respiratory failure and other serious problems. If you have noticed any of these lung disease symptoms, you should go and see a doctor.
- Persistent cough
- Shortness of breath
- Wheezing
- Tightness of the chest
- Fatigue
- Rapid breathing
- Frequent lung infections
- Bluish skin colour on your lips or fingertips
- Inability to talk clearly without becoming breathless
The symptoms listed above need to be taken into consideration for lung disease, as if they persist, you will be best to see a doctor.
When to seek Emergency Care
It is always recommended to seek medical care promptly. Respiratory failure can become extremely dangerous very quickly. You should immediately seek medical care if you observe any of the following:
- Difficulty getting breath.
- Blue coloured lips/face.
- Sudden pain in your chest.
- Confusion or unconsciousness.
- Sudden decline in health.
- Low oxygen readings on a blood monitor.
- Ability to only speak through gasps.
- Diagnosis of Respiratory Failure
The diagnosis is made from;
- Physical Examination
- Pulse Oximetry
- Arterial Blood Gas (ABG) Test
- Chest X-ray or CT Scan
- Pulmonary Function Tests
- Bronchoscopy
- Treatment of Respiratory Failure
Treatment for respiratory failure varies depending on the case and may include;
- Oxygen Therapy
- Mechanical Ventilation
- Medications (bronchodilators, steroids, antibiotics, antivirals, and diuretics)
- Non-Invasive Ventilation
- Pulmonary Rehabilitation
It is important to maintain good lung health, so here are some tips that could help you.
- Quit smoking and refrain from smoking.
- Try to exercise at least 3 times a week and drink enough water to stay hydrated.
- Eat a healthy, balanced diet with enough nutrients.
- Reduce your exposure to air pollution and try to get your vaccinations if available against respiratory infections.
Also, always get any chest conditions treated as quickly as possible.

Frequently Asked Questions
What is respiratory failure?
Respiratory Failure is the failure of the lungs to provide enough oxygen to the body or to get rid of the carbon dioxide it produces.
What are the most important factors causing respiratory failure?
These causes include lung disease (chronic), pneumonia, smoking, heart failure, and severe asthma.
What are the initial indications of lung disease?
Initial symptoms are shortness of breath, wheezing, a persistent cough, extreme fatigue, chest tightness, or infections in the respiratory system.
How dangerous is respiratory failure?
Respiratory Failure can potentially be a fatal medical condition. Immediate medical treatment must be sought.
Can smoking cause respiratory failure?
Smoking damages lung tissues, causing chronic lung disease, which then may lead to respiratory failure.
How is respiratory failure determined?
Blood gas tests and pulse oximetry are common, and other diagnostics include chest X-rays, CT scans, and pulmonary function tests.
Is it possible to prevent respiratory failure?
Yes, through giving up smoking, getting infections and other lung diseases treated quickly, along with preserving lung health through positive living.
Which are the best hospitals for pulmonology in Delhi?
Venkateshwar Hospital has emerged as one of the best hospitals for pulmonology in Delhi, along with other hospitals offering pulmonary treatment services.
