A. Inventions: Dr. Virendra Singh invented three instruments that have immense utility in cure of respiratory patients. Government of India awarded patent of invention to these  instruments ((Invention Patent No. 160580/86, 160764/86 and164780/87)).

  1. He invented Pink city flow meter to measure severity of asthma and smoking induced lung disease emphysema. It helped in diagnosis and treatment of asthma and other respiratory diseases, popularly it is nick named as thermometer of asthma. National Research Development Corporation (NRDC) of the Government of India awarded the Independence Day Award,(Rs 50.000/) the highest award given for the best invention in the country, to Pink City Flow Meter in 1989.    (Published in: Invention Intelligence: Jan 1991:35-37).
  2. Pink city lung exerciser was his second invention. It  is an equipment to perform lung exercises. It is based on principles of pranayama.  Regular use has been shown to cure asthma and other respiratory diseases. National Academy of Medical Science graded it the best bio-engineering work in the country for year 1990-91, and awarded the S S Memorial award. (Published in: Am Review Resp Disease 1990;141:A24, J Asthma 1987;24:355-59).
  3. Hydration attachment to lung exerciser was his third invention.  When used with a Lung Exerciser this invention relieves symptoms and improves lung functions in asthmatic patients. (Published in: J Asthma 1987;24:355-59).


B.Discoveries: He made couple of original discoveries which have been acknowledged by leading international scientists.

  1. Nervous reflex: He discovered a nervous reflex relating patency of nostrils. When we breathe, only one nostril is patent while the other nostril remains blocked. Though this phenomenon was known since long but its mechanism was not known. Dr. Virendra Singh discovered a nervous reflex to explain the mechanism of this phenomenon. The results of experiment were considered very significant at international level and therefore  published in the leading international journal of physiology (J Appl. Physiology 1987:62:91-94). This discovery was among the best discovery and therefore included and appreciated in the year book of pulmonary medicine. (Year book of Pulmonary Diseases 1988-PP 34-35).
  2. Hypothesis: He also evolved a hypothesis relating Asthma and gastro esophageal reflux (GER) or acidity. These are closely linked but the mechanism was poorly understood. Dr Singh discovered an interesting hypothesis to explain the relationship of asthma and GER. It was thought that GER triggers asthma in patients. However, his experimentation showed a reverse relationship. He showed that medicines providing relief in asthma also improves GER. His findings were published in the leading international journal of asthma as original article (J. Asthma 1983; 20:241-43). This hypothesis was proved in the subsequent Western studies. The hypothesis was considered a landmark discovery and was discussed in the editorials of the top international journals with commendable remarks (editorials of  J. Asthma 1983;20:237-38 and Am Rev Respir Dis 1990;141:1391-92). It was also quoted in Respiratory Medicine Book by Murray & Nadel IInd Edition Vol.2 Pg.2424).
  3. Scientific proof of yoga: He also provided scientific proof that yogic breathing (pranayama) helps in  asthma: It was believed that Yoga improves asthma but could not be proved in authentic scientific studies therefore yoga was never advised in treatment of asthma at international levels. Dr Singh carried-out the authentic studies including the first ever double blind placebo controlled study of the yoga. This study showed that yoga improved asthma. (Published in J. Asthma 1987;24:355-59; LANCET 1990;335:1381-83;  Am Review Resp Disease 1990;141:A24, GINA guidelines for Asthma Management 2002 Pg.).
  4. New mechanism of asthma: He discovered a new mechanism in pathogenesis of asthma. Normally allergens cause asthma by inducing inflammation in airway mucosa. However, it is still not known why airway inflammation persists despite removal of allergens? What continues airway inflammation for such a long period is still a mystery. Dr Singh discovered that friction generated during activities causing fast breathing such as coughing may be very high and it may cause injury to airway mucosa. Repeated mucosal injury during coughing in asthmatic airways is the cause for continuance of airway inflammation. (Published in: Am Rev Respir Dis: 1993;147:A832; J Asthma 1999;36:419-426; JAPI 2000;48:501-504; JAPI 2000;48:343-45.)


C. Public welfare activities: Not only scientific works but Dr Virendra Singh has been very active for patient welfare activities.

  1. State of art center creation: He has established the state of art center of division of allergy and pulmonary medicine at SMS Hospital., Jaipur.
  2. Patients motivated to care themselves: During his practice he realised that asthmatic patients passes through phases of well-again and sick-again cycles. These phases are quite painful and patient often stops treatment out of frustration, to further suffer from agony. Simple measures of lifestyle modification and learning about the nature of the disease can protect a patient from the agony of recurrent attacks of asthma. Dr Singh designed life style programs to mitigate asthmatic conditions which have benefited lacs of patients. His audio & video programs on asthma education were graded very useful for millions of asthmatic patients. They are now developed in nine Indian languages and are available free of cost on website
  3. Crusade against tobacco: While treating patients suffering from severe COPD (smoking induced lung disease called dama in hindi) he realised that cessation of smoking was the most effective treatment. Therefore he established Indian Asthma Care society in 1986 to help needy asthmatic patients and to launch a campaign against tobacco. Through IACS pamphlets, booklets, hoardings, audiovisual slides and CD programs were designed and presented at various public platforms benefiting lacs of people. He motivated Sh Dharamveer ji Katewa present secretary IACS, who has filed a number of writ petitions in the courts and persuaded authorities for ban on tobacco, which helped in formation of anti tobacco laws in Rajasthan and ban on gutakha in the country. To help needy patients of respiratory diseases and patients with addiction through IACS he was instrumental in establishing Asthma Bhawan. It is a charitable institution having most advanced center for treatment of respiratory patients and tobacco related patients.
  4. Motivating students to imbibe moral values: In order to motivate children to imbibe good moral character, a program based on principles of Mahtma Gandhi was designed and named “Satvikta ek pahal”. The program is presented to school children apprising them the strength of Gandhi’s character and its relevance to them as students.
  5. Motivating public to work hard and imbibe moral values: Worked as superintendent of SMS Hospital from 1st July 2012 - March 2014. During his tenure the hospital became the biggest hospital of the Country with highest number of OPD patients (over 25 lacs) and number of investigations (over 45 lacs). The number of CT scans done in one day made a world record in Limca book. He tackled the heavy rush by motivation of staff through individual and group meetings. Staff infightings were tackled with regular discussions. Mistake committed by employees were addressed by innovative method of "prayashchit", practiced by Gandhi ji. Tobacco and alcohol addictions of staff and patients were also addressed through innovative skills. The problem of strike was tackled with help of public of Jaipur. People volunteered to work in the hospital and did work of computer, trolley pulling and even cleaning.
