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 air temperature from reaching the skin. There has been very little research done in the genetics behind adaptations to heat and cold stress. Data suggests that certain parts of the human genome have only been selected for recently. Research on gene-culture interaction has been successful in linking agriculture and lactose tolerance. However, most evidence of links between culture and selection has not been proven. 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
