ABSTRACT

En el presente trabajo, se ha analizado el Programa de Entrenamiento Fisiológico en el Departamento de Medicina Aeroespacial de la Dirección de Sanidad de la Fuerza Aérea de Chile, en lo que respecta a incidentes producidos durante el desarrollo de dicho programa y al que fueron sometidos tanto pilotos alumnos como instructores de vuelo de cámara hipobárica, durante los años 1983-1992. En este período se entrenó a 2.118 alumnos en vuelos de hipoxia y vuelos de descompresión rápida no registrándose ningún accidente, teniendo presente además, que los incidentes que se produjeron fueron sin consecuencias graves, tanto para alumnos como instructores. En el período analizado se produjeron un total de 274 incidentes en los alumnos correspondiendo a barotitis, barotitis tardía y barosinusitis, los porcentajes más altos. Asimismo, en los instructores el número total de incidentes fue de 56, siendo barotitis, barotitis tardía y barosinusitis los más frecuentes. Otros hechos importantes son la realización de 23 vuelos médicos y de 24 vuelos de prueba, todos sin consecuencia y con resultados altamente positivos. Cabe destacar que durante este período los incidentes han sido superados efectiva y oportunamente gracias a la preparación, capacidad y a las medidas de seguridad que en cada circunstancia específica se aplicaron

ABSTRACT

Medical certification standards to return to work after coronary bypass surgery in airline, other civilian and military pilots is reviewed. The risk to public safety is assessed, metods used to identify a subgroup of operated pilots with a very low risk of cardiac events are descrihed a well a the follow up requirements. The national and international regulations are reviewed

ABSTRACT

With the advent of a permanently manned Space Station, the longstanding problems of radiation protection in manned spaceflight have acquired an immediacy. This paper endeavors to emphasize the gaps of our knowledge which must be closed for effective radiation protection. The information that is required includes the accurate determination of the exposure inside the space station to the various components of the ionizing radiation, the evaluation of the biological importance of the different radiation qualities and the depth-dose distribution of the less penetrating component. There is also the possibility of an interaction with weightlessness. It is necessary to establish adequate radiation protection standards and a system of dosimetric surveillance. There is a need for studies of methods on the possibilities of hardening selective shielding of the space station. Spaceflight experiments, which might contribute to the solution of some of these problems are discussed.
