Are pacemakers affected at all by long distance flights or particularly high altitude?

Pacemakers: The function of a pacemaker is not affected by long distance flights or altitude. The patient's underlying disease process depending on what it is, could however be affected by either. ...Read more

Pacemaker (Definition)

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

What diet and exercise changes do I need if I am going into a high altitude environment?

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

Is it advisable for one whose asthma is well controlled to travel to places of high altitude?

Is it advisable for one whose asthma is well controlled to travel to places of high altitude?

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 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 more

Help docs! I'm trying to find out what causes high altitude cerebral edema?

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

Does living at high altitude cause any drugs to be less effective?

Does living at high altitude cause any drugs to be less effective?

Unknown: Studies are in progress. Some illnesses act differently making this tough to gauge. Asthma may be better due to fewer 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

What are some ways to simulate high-altitude conditions while training at sea-level?

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

Is it safe to bring my baby into a high altitude?

Is it safe to bring my baby into a high altitude?

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 more

How quickly can your hemoglobin rise in high altitude?

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

I'm wondering if I have any neurologic complications after HACE at high altitude.  Is this possible if I don't have any symptoms I'm aware of?

Possible, not likely: There is always microvascular damage in cases of HACE. After recovery people usually do not have ongoing problems. There are rare cases of vision damage that might subtle. Here is a place to go for information: http://www.altitude.org/altitude_sickness.php
Most importantly, condition yourself and adapt to high altitude situations in the future because damage is cumulative. ...Read more

Drivingfrom 1100ft to 4200 ft tomorrow. Will be at 4200for a few hr I've never been at a high altitude.  I'm overweight and a smoker. Should I worry?

Probably not: Must people at age 27 have normal lungs and even if you are a smoker, must likely you have good lung reserve to be able to breath comfortably at this altitude. Also, people tend not to get in trouble just by "driving" to high altitude. If you stay at high altitude, you can indeed develop high altitude pulmonary edema. But if you are just driving by, it should be ok. Stop smoking/lose weight. ...Read more

How can high altitude affect blood pressure?

Varies: Often unchanged, sometimes hypertension temporarily worsens for the 1st 1-2 weeks at altitude and then returns to normal. We guess this is related to stress hormones or unknown cause and more often in those with unstable pressure to begin with. In rare situations, it may drop. Stay on your medicine, cautious with salt, & get seen if headache, chest pain, short of breath, or concerns beyond that. ...Read more

Holiday at high altitude (7, 000 to 8, 000 ft). What effect will this have on my sleep apnea?

Not a problem: Assuming your general health is good enough to permit higher altitudes, just use your CPAP machine as usual. It will work as it always does. Of course, you will have less oxygen in the ambient air, but it will continue to do its job. If you don't have a cpap, get one, or if intolerant of its use, see your dentist about having an oral appliance made as an alternative. ...Read more

High Altitude (Definition)

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
