ويژگي هاي انتقال با هلي كوپتر سرعت قابليت دسترسي محدوده عملياتي اندازه كابين ارتعاش سروصدا
امنيت از جنبه هوانوردي و فني از جنبه پزشكي
چه وقت ازAMTاستفاده ميشود ؟ ـ امداد ـ انتقال بين بيمارستاني فوري
جنبه هاي پزشكي پرواز در انتقال هوايي بيماران اتمسفر تركيبات اتمسفر فشار درجه حرارت هيپوكسي
جنبه هاي پزشكي پرواز در انتقال هوايي بيماران • تغييرات حجم گازها • رطوبت هوا • شتاب • ارتعاش • صدا
AIR EVACUATION • Physiological Considerations Of Air Evacuation • 1-Changes In Barometric Pressure • 2-Variation In Partial Pressure Of Oxygen • with Altitude pressure • 3- Effect Of Acceleration/Deceleration and • Angle of Climb/Descent 4- Noise, Vibration, humidity , light problems , • Spase limitations
Changes in barometric pressure 1-Open Head Injuries 2-Facial Fracturel/Specially Involving Sinuses 3-Open Eye Injuries 4-Pneumothorax 5-Decompression Sickness 6-Air Emboil 7- GasGangrene
سه راه براي پيشگيري از عوارض ناشي از تغييرات فشار بارومتريك يكي حفظ ارتفاع پروازي در نزديكترين نقطه ممكن به سطح دريا دوم استفاده از آمبولانس هوايي داراي كابين هواي فشرده سوم پيش بيني و تخليه فضاهاي حاوي گاز آزاد تا حد امكان

Considerations in the scen of accident : 1 - The need for an air evacuation 2 - Aircraft selection 3 - Preflight comunication with flightcrew 4 - Preflight comunication with ambulance dispatch and hospital 5 - Checklist prior to aircraft arrival 6 - safty procedures around hellicopter and fixed-wing aircraft 7- pre take-off checklist 8 - Inflight patient monitoring 9 - Backup procedures in the event of equipment failure. Unavailability of aircraft poor weather conditions.
