• Population density : 964/km2
• M:F – 100.3: 100
• Population 14 crore 79 lac (2010 – 2011)
• Current national population growth 1.35%

The proposed Tk 8889 crore in national health
budget 2011 is too little for over 150 million of people.
The per capita allocation in healthcare is Tk 590 or
$7.5 per year per person.
In USA, health budget is 8,047 US dollar per person
& In UK, 3713 US dollar per capita per year.

![Page 78: Management of Cardiovascular problems in pre-hospital settingbsmedicine.org/congress/2012/Dr._Rafique_uddin.pdf · •Population density : 964/km2 •M:F – 100.3: 100 •Population](https://reader035.vdocuments.mx/reader035/viewer/2022081607/5f0208b87e708231d4023fad/html5/thumbnails/78.jpg)
Conclusion
• Teaching should be problem based not on topic based.
• Doctors must be competent enough to address the cardiac emergences like Sudden Cardiac Death, Syncope or Dyspnoea at local setup promptly.
• They must learn when, how, where to refer after settling the acute condition.

Conclusion
• Doctors should be capable enough to individualise each patient and their local clinical facilities and feasibility of transportation to higher centre.
• BLS management training should be compulsory to all Doctors, paramedics.
• We also recommend basic life support management training should be included in general education.
