In the case of a medical emergency such as an out of-hospital cardiac arrest, the chances of a person's survival decrease rapidly if they are not attended to immediately. Modern hospitals well equipped to deal with such a situation however, an ambulance may get stuck in traffic and it may take responders time to reach locations deep within a building. Each year between 180,000 and 400,000 people die due to cardiac arrest. However, it is possible to reduce this number. Unmanned Aerial Vehicles (UAV) has regularly been used for remote sensing and aerial imagery collection, but the technology exists to allow the use of drones to respond to medical emergencies. To ensure that drones can reach the victim and provide medical aid, a framework for reacting to emergency circumstances, is required. This paper proposes a system-of systems-based framework that is capable of responding to one of the most acute medical emergencies, a heart attack. The proposed architecture consists that work in coordination to ensure that the drone can achieve safe flight and provide medical aid. An autonomous command and control system is discussed. This system also allows manual control from a remote location.

ALRTI are one of the commonest causes of morbidity and mortality in children in developing countries. Aim of the study was to evaluate children with severe LRTI (pneumonia) correlate it with radiological findings and bacteriological examination, to identify the risk factors and to study the efficacy of various antibiotics that were used routinely in our sector. This was a prospective clinical study of severe LRTI(pneumonia) conducted on 200 children who were admitted to Pediatric ward from Oct 2010 to Sept 2012 at Govt. General Hospital, Guntur, AP. Children from 1month to 60 months included in the study. Detailed history and clinical examination findings were documented. Routine investigations like CBP, ESR and CXR were done for all cases and blood cultures were done in relevant cases. All patients received antibiotics and supportive care. We found most common age group from 1 month to 1year, males were more affected than females with ratio 1:1.9. Almost all patients presented with symptoms and signs like hurried breathing, cough, fever, chest retractions, crepitations. Symptoms and signs mentioned by WHO, ARI control programme were very sensitive and can be applied to Hospitalized children. Most common type of sever LRTI was Bronchopneumonia (83%). Most common risk factor was PEM of various grades (52%) and anemia, incomplete immunization being other risk factors. Blood culture was positive only 7.8% of cases. Majority (83%) responded to first line antibiotic like crystalline penicillin and amikacin.
