In aviation, pressure suits protect fighter pilots from hypoxia / altitude sickness, and g-suits from the adverse effects of acceleration (gravity-induced loss of consciousness, or G-LOC). The most extreme environmental suits are used by astronauts to protect them during ascent and while in the vacuum of space: space suits and space activity suits. Such suits are self-supporting, and include a supply of oxygen for the wearer.
Obesity hypoventilation syndrome is defined as the combination of obesity (body mass index above 30 kg/m2), hypoxia (falling oxygen levels in blood) during sleep, and hypercapnia (increased blood carbon dioxide levels) during the day, resulting from hypoventilation (excessively slow or shallow breathing).[2][3] The disease has been known since the 1950s, initially as "Pickwickian syndrome" in reference to a Dickensian character but currently under a more descriptive name.[2]

"A salad’s healthy, right?” she asked. Of course the objective answer is yes. But my answer was more complicated."
"The problem in obesity is not excess weight," Lustig says, in the central London hotel that he has made his anti-metabolic illness HQ. "The problem with obesity is that the brain is not seeing the excess weight." The brain can't see it because appetite is determined by a binary system. You're either in anorexigenesis – "I'm not hungry and I can burn energy" – or you're in orexigenesis – "I'm hungry and I want to store energy." The flip switch is your leptin level (the hormone that regulates your body fat) but too much insulin in your system blocks the leptin signal.
Obesity hypoventilation syndrome (also known as Pickwickian syndrome) is a condition in which severely overweight people fail to breathe rapidly enough or deeply enough, resulting in low blood oxygen levels and high blood carbon dioxide (CO2) levels. Many people with this condition also frequently stop breathing altogether for short periods of time during sleep (obstructive sleep apnea), resulting in many partial awakenings during the night, which leads to continual sleepiness during the day.[1] The disease puts strain on the heart, which eventually may lead to the symptoms of heart failure, such as leg swelling and various other related symptoms. The most effective treatment is weight loss, but it is often possible to relieve the symptoms by nocturnal ventilation with positive airway pressure (CPAP) or related methods.[1][2]

缺氧（hypoxia），即生物的組織或細胞不能獲取足夠的氧，或能獲取但無法運用。缺氧可能是全身性的，也可能只有身體部份部位缺氧。缺氧多半是病理過程，不過正常人動脈內的氧氣濃度也會因劇烈運動或是低換氣培訓[1]而降低。
一般人在高海拔下也會有缺氧的情形，也就是高山症，可能會造成以下嚴重的併發症：像是高山肺水腫症（HAPE）或是高山腦水腫症（HACE）[3]。一般人在呼吸氣體中氧氣濃度過低時，也會有缺氧的症狀，尤其是在使用控制呼吸氣體氧體濃度的再生式氧氣系統進行潛水時。另外在高原訓練時會刻意用輕微且沒有傷害性的間歇性缺氧來訓練運動員，可以訓練耐力以及新陳代謝[4]。
缺氧也是早產兒的重症之一，會出現缺氧的主要原因是因為肺是胎兒在體內最晚發育的器官。為了讓肺部可以將氧氣擴散到血液中，再運送到人體。有缺氧風險的早產兒一般會放在有持續性正壓呼吸器的保溫箱內[來源請求]。
