    Dear Sir, it is said that in ILD / restrictive lung disease lings become hard and do loose it's elasticity. Under this circumstances, may lung rehabilitation exercises like incentive Spirometer exercises, pursued lip exercises, diaphragm exercises, water bubbling exercise, balloon 🎈 exercise may be beneficial or not to increase lung capacity/ lung problem due to restrictive lung disease?

      Dear @sukhendu1974,
      Thank you for your insightful question! You're correct that in Interstitial Lung Disease (ILD) and other restrictive lung diseases, the lungs lose elasticity and become stiff. Lung rehabilitation exercises, including those you mentioned such as incentive spirometry, diaphragm exercises, water bubbling exercises, and balloon exercises, can indeed help improve lung capacity, muscle strength, and breathing efficiency. These exercises may not reverse the damage but can enhance the patient's quality of life by improving lung function, preventing further decline, and promoting better oxygenation.
      Balloon exercises, for example, strengthen the diaphragm and intercostal muscles, while pursed-lip breathing helps in controlling shortness of breath. However, the effectiveness of these exercises can vary depending on the severity of the disease, so it's always best to follow a rehabilitation program tailored by a specialist.
      I hope this helps, and feel free to reach out with any more questions!
      Best regards,
      Med Madness

      For the bronchodilator test, commonly used doses are:

      Ipratropium Bromide: 80-160 mcg, delivered via MDI or nebulizer. thank you. let me know if you have any more question.

    Hello, in VC volume test of my machine, it measures the following parameters below, but unfortunately it is not calculating TLC , RV, FRC, RV/TLC. So how can i calculate them? so my machine measures the following automatically: vital capacity,inspiratory volume,expiratory reservevolume,inspiratory reserve volume,expiratory vital capacity,inspiratory vital capacity,tidal volume,minute ventiation, resp rate,tidal inspiratory time,tidal expiratory time,total respiratory time, ti/te, ty/ti,ti/ttot,te/ttot. Which of these are importantparameter to decide restricitve or obstructive?

    • @MedMadness
      @MedMadness  2 ปีที่แล้ว

      In restrictive disease, all volumes and capacities are reduced . FEV1/FVC ratio is 70 % or more. In Obstructive disease, residual volume, total lung capacity, functional residual capacity is increased. FEV1, FVC, ERV, IRV, IC, VC are all decreased. FEV1/FVC Ratio is also less than 70 %.

    Should we do spirometry test to covid patients to detect post covid fibrosis? Is that covid fibrosis different from restrictive lung diseases?

    • @MedMadness
      @MedMadness  7 หลายเดือนก่อน

      Yes, performing spirometry tests on COVID-19 patients can help detect post-COVID fibrosis. This is because spirometry can assess lung function and identify restrictive patterns, which are characteristic of lung fibrosis. Post-COVID fibrosis is a type of restrictive lung disease, similar to other forms of lung fibrosis, where lung volumes are reduced and lung compliance is decreased. thank you. let me know if you any more questions.

    How do you get rid of those fibrosis?

    • @MedMadness
      @MedMadness  5 หลายเดือนก่อน +1

      Fibrosis can be challenging to treat and is often managed rather than completely cured. Treatment options may include antifibrotic medications such as pirfenidone or nintedanib, particularly for idiopathic pulmonary fibrosis. Addressing underlying conditions, such as controlling inflammation with corticosteroids or immunosuppressants, can also be beneficial. It's essential to work with a healthcare provider to determine the best treatment strategy based on the specific type and cause of fibrosis

    How to treat lung fibrosis as GP?

    • @MedMadness
      @MedMadness  7 หลายเดือนก่อน

      thanks for your question. As a General Practitioner (GP), treating lung fibrosis involves a combination of approaches:
      Referral to a Specialist: Lung fibrosis often requires specialized care. Refer the patient to a pulmonologist for detailed evaluation and management.
      Medications: Prescribe medications like antifibrotic agents (e.g., pirfenidone, nintedanib) as recommended by a specialist.
      Oxygen Therapy: Provide supplemental oxygen if the patient has low blood oxygen levels.
      Lifestyle Changes: Encourage smoking cessation, healthy diet, and regular exercise to improve overall health.
      Vaccinations: Ensure the patient is up-to-date with vaccinations like influenza and pneumococcal vaccines to prevent respiratory infections.
      Pulmonary Rehabilitation: Recommend pulmonary rehabilitation to improve the patient's physical condition and quality of life. Let me know if you have any more doubts.

    How could FEV1 ever be greater than FVC? Isn't that saying you are breathing out more in that first second than you breath out at all, which would be impossible? Like you can't breath out 3L in the first second if you only breathed out 2L total. Or am I misunderstanding it?

      @@MedMadness Thanks for the quick reply! I think I understand the overall idea so I see how the % can increase, but I'm referring to what you wrote at 4:00. You put the FEV1 as 3 with the FVC as 2. That would make the ratio 1.5 or 150%. If I'm understanding it correctly, then that would be saying in the first second the exhaled 3L of air, but the entire volume of the FVC was only 2L which wouldn't make sense.

      @@pohelloop Numbers are just an example to explain the ratio easily. In restrictive disease ( in this example ) FVC decreases from 5 to 2 and Fev1 decreases from 4 to 3 . This clearly shows that Fvc is more decreased than FeV1 because of the underlying pathology ( say fibrosis ) . Don't take the numbers as real . Thank you

      @aswinikumar9416 Thank you for the clarification. If your FEV1/FVC ratio is calculated as 83% when using predicted values, it falls within the normal range, which is typically above 70% for adults. The 70.30% you mentioned might be based on absolute measured values rather than predicted percentages. Since your doctor has confirmed that the report is normal and you do not have concerning symptoms like breathlessness or wheezing, there's no need to worry. If you're still uncertain or have symptoms, consider discussing this further with your healthcare provider for more clarity
