Are Pacemakers Affected At All By Long Distance Flights Or Particularly High Altitude
A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more
Water and cardio: It is important to drink more water. Also, doing cardiovascular exercises can help aclimate you to the new environment sooner. I'm presuming that we are discussing places like colorado or similar mountain areas which are typically a mile above sea level. For extreme high altitudes, such as himalayan mountains, there are significant dangers from altitude and that is a more complicated answer. ...Read more
What do YOU mean by: "well controlled"? Asthma in america study reveals that most patients rating their asthma well controlled are not in control by the standards of allergists & pulmonologists. A simple yardstick is the rule of twos. Asthma is in control when albuterol use <3x/week & waking up at night from asthma <3x/month & exacerbation of asthma requiring Prednisone or er visit <2x/year. Pass & you're good to go. ...Read moreSee 1 more doctor answer
Can high altitude cause hypertension or aggravate it if it already exists? If so what causes this?
No, Internal Control: Bp: a result of cardiac output vs. Average resistance of the 20, 000 to 30, 000 end arteries (arterioles) which determine blood flow to each capillary bed, both co ; size of all arterioles (degree of constriction) are under split-second control from brain ; constantly being adjusted. BP is just a momentary result. Brain integrates many variables, including perceptions/feelings ; adjusts accordingly. ...Read more
Do people with hemoglobinopathy E need to take precautions when traveling to places at high altitude?
Depends : If you are hetero-zygote for Hb E, you need not be concerned. If you are homozygous, then it would depend on your hemoglobin level and associated issues such as alpha thalassemia. It would be prudent to discuss it with your doctor. ...Read more
What could it be to have high hemoglobin? No smoke, no live on high altitude, no kidney issues. Please help!
Agree and...: P vera is rare ; genetic. Be sure you are talking about truly high number. Other causes are sleep apnea, lung disease, non smoking chronic carbon monoxide exposure, liver disease, kidney cysts or obstruction that may be unknown, adrenal causes, very rare tumors that put out epo (which tell the body to make more hemoglobin) no need to guess though--your provider will be able to sort it out for you. ...Read moreSee 1 more doctor answer
Hypoxia: When a person goes to high altitude, they are naturally exposed to hypoxia as oxygen content decreases with elevation. Most who climb can to aclimatize to this change. However, in certain people they are not able to compensate. The proton pumps that maintain the blood brain barrier cease to function and there is extra fluid (edema) in the brain that leads to brain swelling. This can lead to death. ...Read more
Unknown: Studies are in progress. Some illnesses act differently making this tough to gauge. Asthma may be better due to less pollutants up high. Altitude makes immune systems slightly less strong and can delay wound healing. High blood pressure can be a bit harder to control but not always--is it because the medicines are less effective or the altitude impacts the body? Still being sorted out. ...Read more
Best very expensive: Elite athletes use methods to fool the body it is training at altitude to stimulate erythropoietin to make more red cells and to increase 2.3-dpg, a chemical that impacts oxygen movement from red blood cells to working muscles. This requires sleeping in oxygen low rooms at night (pumped in nitrogen gas) etc.The mask based system has potential but is not to be used during exercise only at rest. ...Read more
Yes: Travel to high altitude (above 8000 ft / 2400 m) can be very stressful on both parents and babies. Babies have a limited ability to communicate if they are having difficulty at high altitude. Older children and adults are fatigued, have nausea & headache, and are short of breath. Waiting until the child is able to talk makes monitoring for altitude sickness symptoms easier. Symptoms mean descend. ...Read moreSee 1 more doctor answer
Hemoglobin at altitu: Weeks to months depending on the altitude. The immediate response to altitudes over 10, 000 feet is an increase in the depth and rate of breathing to help maintain the level of oxygen in the blood. As the length of exposure persists, the kidneys will start producing a hormone to increase the rate of production of red blood cells to pick up and carry more of the available oxygen at that altitude. ...Read more
Altitude Sickness: Leh, altitude 11500 ft (3500 m), is at the defined border between high and very high altitude. Low o2, pulmonary and cerebral edema are the main concerns with altitude sickness, which is made worse by rapid ascent. Precautions and treatment will depend on your health. You should consult with your physician about specifics. ...Read moreSee 1 more doctor answer
My BP suddenly went dangerously high after living at high altitude for over 6 months. What is the reason for this?
Not the cause: It's unlikely that altitude is the cause. See this science-based article from the u of hawaii: http://www.Ncbi.Nlm.Nih.Gov/pubmed/10453102. ...Read more
As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your ...Read more
