Atelectasis development of atelectasis include: type of surgery (thoracic, cardiopulmonary surgeries), use of muscle relaxation, obesity, high oxygen, the lower lung segments. Factors not associated with the development of atelectasis include: age, presence of COPD or asthma, and type of anesthetic. In the early 1950s, in UK aviation medicine, the condition "acceleration atelectasis" was given the name "Hunter Lung" due to its prevalence in pilots of the transonic fighter jet the Hawker Hunter, which used a 100% oxygen schedule. Clinically significant atelectasis is generally visible on chest X-ray; findings can include lung opacification and/or loss of lung volume. Post-surgical atelectasis will
Cold and heat adaptations in humans Cold and heat adaptations in humans Cold and heat adaptations in humans are a part of the broad adaptability of "Homo sapiens". Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and cultural practices, but less research on genetic adaptations to cold and heat temperatures. The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F).
