When you are jogging, do your muscles use more oxygen and thus release more carbon dioxide into the blood?

When you are jogging, do your muscles use more oxygen and thus release more carbon dioxide into the blood?

Yes: Jogging definitely increases oxygen consumption by the muscles and production of multiple products from this including carbon dioxide. One of the ways we compensate for this is by breathing harder as we exercise. ...Read more

Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more

How do muscles become efficient at extracting oxygen from blood?

How do muscles become efficient at extracting oxygen from blood?

The muscles must: Deliver adequate microcirculatory vessels to the muscle group...Exercise may stimulate the cytokines (vegf) to do so. ...Read more

What carries oxygen to the muscles?

What carries oxygen to the muscles?

The blood.: Blood gets oxygenated as it passes through the lungs. The blood then carries that oxygen to the organs and structural elements of the body, including the muscles, where that oxygen is released and utilized. ...Read more

I am exercising to try and heal from an accident, but I keep feeling fraying/tearing. Muscles on sides of neck feel like they are not getting oxygen.?

I am exercising to try and heal from an accident, but I keep feeling fraying/tearing. Muscles on sides of neck feel like they are not getting oxygen.?

Whiplash: Healing is directly proportional to the energy absorbed during the injury. So, harder impact=longer healing time. Generally speaking, this is purely a muscular problem and worsens for a day or two, and then improves thereafter over days or weeks. Rarely does whiplash produce lasting symptoms over 2-3 months (unless a lawsuit is involved, then all bets are off). ...Read more

What is the oxygen carrying protein of muscle cells?

What is the oxygen carrying protein of muscle cells?

Oxygen: The oxygen carrying protein in the whole body is hemoglobin, found in the blood. ...Read more

Can pinched nerve in the neck cause low blood flow to the body along with less oxygen to the muscles. Feel like I might have a pinched nerve in the n?

Can pinched nerve in the neck cause low blood flow to the body along with less oxygen to the muscles. Feel like I might have a pinched nerve in the n?

Nerve impingement: Can be caused by being sandwiched between two spinal bones, pressed by a bulging disc. It can cause muscle spasm and back pain. This condition must be professionally managed. See an interventional pain management specialist for definitive diagnosis and management. See your dentist for tooth pain. ...Read more

Do your muscle need oxygen I lose muslce in my legs and shoulder?

Yes: Muscles need oxygen & nutrients from food to create energy to keep the cells that make up your muscles alive. The most likely reason for your muscle loss is inactivity. If you are not using those muscles, they go away. Another common reason for muscle loss is not eating enough. If your body is not getting enough calories, it takes protein from your muscles to make energy to keep your organs alive. ...Read more

If my anemia has gone undiagnosed 2 years or more could irrepairable damage have been done to my oxygen deprived heart muscle?

If my anemia has gone undiagnosed 2 years or more could irrepairable damage have been done to my oxygen deprived heart muscle?

Unlikely: Anemia often produces symptoms before it can cause anyorgan damage. Heart is quite sensitive to low oxygen and will produce symptoms of pain in the chest called angina which comes on physical strain and goes away on rest. Unless you have such symptoms of angina you have not risked your heart for any damage.
What is your hemoglobin (HB) level? If it is >8 grams, you are not going to have any damage. ...Read more

If a lack of oxygen hurts and damages your heart muscle, then how bad is it to hold your breath?

If a lack of oxygen hurts and damages your heart muscle, then how bad is it to hold your breath?

Depends: In general a person can not hold their breath long enough to cause heart damage because1: a neurally mediated reflex triggered by the buildup of carbon dioxide is present and will override the breath hold and 2: the duration of time absent complete oxygen required to damage heart muscle is 15-30 minutes. ...Read more

No: No, it is caused by byproducts of the accelerated metabolism during exercise. ...Read more

I know that inhaled diesel exhaust particles that get deep into the lungs have been shown to trigger episodes of reduced oxygen supply to the heart muscle. Is this something that will simply be short term only while exposed or will it be permanent?

I know that inhaled diesel exhaust particles that get deep into the lungs have been shown to trigger episodes of reduced oxygen supply to the heart muscle. Is this something that will simply be short term only while exposed or will it be permanent?

Pollution: Such inhalation affects the lungs primarily and would not be expected to cause permanent heart damage once you remove yourself from this type of air pollution. However chronic low oxygenation of the blood does in time affect heart function by creating strain on the right ventricle. Hopefully you will avoid this type of pollution. ...Read more

How do they test for arterial insufficiency in a leg where the calf muscle cramps or reflects oxygen insufficiency, when there is a pulse at the foot.

How do they test for arterial insufficiency in a leg where the calf muscle cramps or reflects oxygen insufficiency, when there is a pulse at the foot.

Ultrasound first: First, a doppler exam of your pulses is performed. There are 3 major arteries below the knee. If 1 or more are missing or of poor amplitude, an arteriogram is perfomed. Sometimes at the same sitting, a narrowed artery can be dilated. ...Read more

Can turbinate hypertrophy cause neck muscle twitching due to lack of oxygen and sleep apnea? Is nasonex (mometasone) effective?

Can turbinate hypertrophy cause neck muscle twitching due to lack of oxygen and sleep apnea? Is nasonex (mometasone) effective?

2 separate problems: 1. See ENT for turbinate problem evaluation and treatment. You also should ask for the overnight sleep study (PSG) to diagnose OSA. Nasonex (mometasone) is not effective for obstructive sleep apnea. 2. Muscle twitching is a potential side effects of fluoxetine. Good luck. ...Read more

I'm 18 & my oxygen saturation is 95. Is this bad?

I'm 18 & my oxygen saturation is 95. Is this bad?

No: Any oxygen saturation above 90% is ok, but most healthy people have oxygen sats between 95-100%. But, even being 94% can be normal.

Oxygen saturation varies minute to minute, so one simple measurement may not give the whole picture. Moreover, pulse oximetry can be notoriously inaccurate, so make sure the measurement is truly accurate.

But, in general, 95% saturation is great. ...Read more

I'm 59 years old can low oxygen at night cause headaces that don't go away doing the day?

Check with your doc: Low oxygen shows there is a problem and your brain cells and heart cells are at risk. A sleep study is certainly useful to fix the problem. Check with your sleep doc asap. ...Read more

I'm wondering why are heavy smokers with damaged lungs put on pure oxygen to keep them alive?

I'm wondering why are heavy smokers with damaged lungs put on pure oxygen to keep them alive?

Easier to breathe...: "room air" is approximately 21% oxygen. People need oxygen to make their vital organs (brain and others) function well. If a person's lungs are damaged, that person may not absorb oxygen well. By administering oxygen to the patient, the percentage of oxygen in the "air" is increased allowing for the person to oxygenate their blood more readily and thereby deliver oxygen to vital organs. ...Read more

Oxygen (Definition)

Oxygen is a gas that the cells in your body need to work properly. The air we breathe normally has 21% oxygen. A maximum of 100% oxygen can be given. Babies with heart or lung problems may need ...Read more
