![]() Growing awareness of the possible health risks of an altitude sojourn motivates a rising number of people to seek medical advice prior to travel.Ĭonsequently, clinicians are regularly confronted with difficult questions about the health risks of mountain travel or altitude sojourn by their patients. ![]() Acute mountain sickness (AMS), with headache, gastrointestinal symptoms, weakness and sleeping difficulties, in the mild form to acute high altitude cerebral oedema (HACE), in the most severe form, as well as high altitude pulmonary oedema (HAPE) can develop when travelling to high altitude. Previous literature has shown that all individuals travelling to moderate (> 1500 m) or high altitude (> 2500 m) regions are at risk of experiencing dyspnoea, disturbed sleep with periodic breathing and exercise limitation, especially when combined with rapid ascent. Although age in itself is not a risk factor for altitude intolerance, older patients are more prone to pulmonary comorbidities. A tourist enquiry in 2015 showed that 11.8% of Valais visitors is over 65 years of age. Older patients constitute a significant part of the population in mountain resorts located at moderate to high altitude (1500–2500 m). Rapid evolution in travel options by expanding road, rail, cable cars and airway networks have made moderate to high altitude destinations increasingly accessible and affordable for people of varying age, health condition and fitness. Second, we seek to summarise for each underlying lung disease, a personalized pre-travel assessment as well as measures to prevent, monitor and mitigate worsening of underlying respiratory disease during travel. First, we aimed in this review to evaluate health risks of moderate and high terrestrial altitude travel by patients with pre-existing lung disease, including chronic obstructive pulmonary disease, sleep apnoea syndrome, asthma, bullous or cystic lung disease, pulmonary hypertension and interstitial lung disease. A comprehensive literature search was conducted. However, limited data are available on the risks faced by patients with pre-existing lung disease. These changes, as well as general altitude related risks have been well described in healthy individuals. Exposure to a hypobaric hypoxic environment at altitude challenges the human body and leads to a series of physiological adaptive mechanisms. As a result, more and more individuals with varying degrees of respiratory conditions wish to travel to altitude destinations. “If anything the mistake is in nature.Once reserved for the fittest, worldwide altitude travel has become increasingly accessible for ageing and less fit people. Everything is on hold while you are being centrifuged.” ![]() ![]() Cutting all connection to the world we live in communication, responsibility, weight. Laslowicz and his colleagues persisted and eventually produced a number of impressive devices such as the Spheroton Centrifuge (1982), the Wedding Cake (1985), the High Altitude Conveyance (HAC 1991), the Expander (1993), the Dandelion prenatal ride (1996), the SPC Steam-Pressure Catapult (2003) and others. Nick Laslowicz from the Instutue of Centrifugal Research in Florida, takes us through the story of investigating the effects of kindergarten rides on the learning curve of four-year-old children.Eventually the researches came up with the idea of building a larger, stronger and faster device that would allow them to examine the effects on adults.ĭespite the initial setback of the first prototype falling apart after reaching 6 g’s, Dr. The Centrifuge Brain Project is a 6 min short mdockumentary about the scientific experiments with amusement park rides in general and their effects on the brain in particular.
