What functions of the respiratory tract are lost with use of a ventilator and trache tube?

The upper respiratory tract also functions to warm and humidify the air you breath so this is one function that is lost. To counter this the air/oxygen mix should be warmed and humidified. If not the lining of the respiratory tract would become dried and damaged as a result.\n\nThe upper respiratory tract also serves to filter particles from the air so filters must be attached to the ventilator.

Lung is a special organ which allows gas exchange. Air passes through trachea, bronchi, bronchioles and finally alveoli. Oxygen will diffuse form the alveoli into the blood plasma whereas the diffusion of carbon dioxide occurs in opposite direction.

When we breathe in, we take in O2 which is distributed to all around our body via the red blood cells. Every cell needs O2 to survive, therefore without the respiratory system, cells would not receive O2 and therefore would die. O2 is also used in many other metabolic pathways in the human body, and so without it we would die.

These are three different conditions and could take pages to describe. \n \nAsthma:  Is a reaction of the the small tubes in the lungs to a virus, an allergen, cold air, or various other factors.  The tubes react in three ways.  One they narrow and therefore produce a wheezing sound when breathing out, two they produce mucus thus clogging the tubes even more then three they swell.  The best way to prevent asthma is keep the tubes in good shape. (e.g.. use a preventative)Asthma is treatable but if acute can make it difficult to talk so it is a good idea to not leave it too long before seeking help.  (A good friend died on his neighbours front step unable to call out)\n\nEmphysema:  Is a deterioration of the the air sacs at the end of the tubes described above.  Commonly caused by smoking for years (both by direct smoking or second hand smoking).  The air sacs loose there elasticity and do not work as well as they used to therefore limiting the persons ability to exchange oxygen by limiting the amount of air breathed in.  Emphysema is not reversable.\n\nLung cancer:  A growth of cancerous cells within the lungs that destroys good lung tissue and eventually will take over if not treated.\n\nAll these conditions have the ability to severely limited your life and have the capacity to kill you.  The tubes of a person who has died of an asthma attack when dissected are like solid branches of a tree made of mucus, therefore not letting any air in or out.

There are problems that can crop up.  The biggest would be food or drink going down the wrong way.  Usually pain full and distressing but only rarely serious as the bodies natural defences tend to stop it quickly.\n\nThe biggest risk is probably from inhaling saliva especially if it is contaminated with gastric juice.   This can cause inhalation pneumonia but it is highly unlikely and if it did happen is likely to be mild.  Recommend that you avoid alcohol, or spicy food in the evening. \n\nTwo important things.  Firsts is common sense - if in any doubt about contamination of the bronchial tubes or lungs seek advice.\n\nSecondly - keep swallowing.  Repeated use of the muscles will strengthen them and may well act to restore more feeling and mobility.\n\nGood luck.

Here is some info.  You can find more on the site...\nEar tubes are small tubes made out of plastic or metal that are placed into the ear drum to ventilate the middle ear. The middle ear is that part of the ear between the ear drum and the hard bone surrounding the inner ear. The middle ear is, under normal circumstances, filled with air at the same pressure as the surrounding atmosphere. The pressure is maintained at this normal level by a natural tube called the eustachian tube. When pressure gets greater or less in the middle ear (for example, when changing altitudes in a plane) the eustachian tube opens, causing the ears to "pop" and the pressure to equalize. The eustachian tube also opens during swallowing, chewing, or other jaw movement without producing the pronounced popping sensation.\n\nIf the eustachian tube is not functioning properly, it will not open. This causes the pressure in the middle ear to drop. High negative pressure in the middle ear will draw fluid out from the surrounding tissue and cause fluid to accumulate in the middle ear. This fluid can become infected, setting the stage for recurrent ear infections (otitis media). The infection causes swelling, making it even more difficult for the eustachian tube to open.\n\nEar tubes are placed to break this cycle, allowing the ears to drain and to ventilate. The drainage acts in the short term to remove any fluid in the middle ear. The ventilation function is the more important long term benefit of the tube. With ventilation the lining of the middle ear can return to normal. Since the pressure in now equalized with the surrounding air, there is no accumulation of new fluid and the chances of additional infections is reduced.\n\n \n\nThese are examples of two type of ear tubes. The diameter and the width of each tube is about 3 mm (one-eighth inch).\n\nEar tubes can also help out in those cases in which there is negative pressure in the ear but no fluid. The negative ear can lead to feelings of discomfort or fullness and hearing loss. If the symptoms do not improve with medical treatment, an ear tube can equalize the pressure in this case as well.

haha the answer above me is funny...what what exactly do you want to know about it? theres a lot to do with respiration...theres inspiration where the air is taken in..this is caused by a contraction of the diaphragm..thens there structures like the epiglotis, trachea, pharynx...then the oxygen goes to your lungs..where gas exchange occurs in the alveoli's...this is done by some complicated process that i dont understand really..i didnt really pay attention during this part of physiology/biology class. haha. anyway, the oxygen is picked up by the pulmonary artery and goes to the rest of the body through the aorta...uhh, i can think of anything else..hope this helps!

Depends on where the fluid is located\n\n1. In the airway - any infectious or inflammatory process - pneumonia (bacterial or viral), abscess, long-standing uncontrolled asthma, fungal infections\n\n2. Between the airways and alveoli - edema from leaky capillaries or protein loss, interstitial disease from rheumatic conditions (lupus, sarcoidosis), infections (viral, fungal)\n\n3. Next to the lungs in the chest cavity (A.K.A. a pleural effusion)  This can also be due to infection or inflammation (pneumonia, rheumatic disease, protein loss)\n\nProtein loss can be from renal failure (acute or chronic) or liver disease (acute failure or chronic - cirrhosis, etc...)

These are very different aspects of functional biology.\n is the obstruction of the flow of air into a person's lungs by a foreign object, commonly food. Choking can become a medical emergency, as choking prevents breathing and will thus starve the brain and other organs of oxygen.\n\nIf the casualty can still cough effectively they will probably be able to cough up the offending object. The first aid at this point is to stand by and encourage coughing.\nA cough is a sudden, often repetitive, spasmodic contraction of the thoracic cavity, resulting in violent release of air from the lungs, and usually accompanied by a distinctive sound. Cough is an action your body takes to get rid of substances that are irritating the air passages. A cough is usually initiated to clear a buildup of phlegm in the trachea; air may move through this passage at up to 480 km/h (300 mi/h) during a contraction. Coughing can also be triggered by a bolus of food going down the trachea instead of the esophagus, due to a failure of the epiglottis, although this may result in choking instead. Frequent or chronic coughing usually indicates the presence of a disease. Provided the patient is a non-smoker and has a normal chest xray, the cause of chronic cough in 93% of all patients is due to asthma, reflux (heartburn) or post-nasal drip. Other causes of chronic cough include chronic bronchitis and medications such as ACE inhibitors. Coughing can happen voluntarily as well as involuntarily.

The respiratory system starts with the nose and mouth where we breathe in oxygen and expel carbon dioxide. The oxygen travels down the windpipe(trachea) and into the bronchi contained in each lung. The windpipe splits into two bronchi which go into each lung. Each bronchi spreads into smaller structures called bronchioles. These spread through each of the lungs. Each bronchiole has a number of smaller structures known as alveoli. The alveoli have a very large surface area and is where gas exchange occurs. Oxygen replaces carbon dioxide and is taken to all parts of the body via the bloodstream. Carbon dioxide is toxic to humans in high concentrations which is why it is breathed out. \nThe main structures are nose, mouth, windpipe, lungs, bronchi, bronchioles, alveoli.

first: air is warmed by the rich vascular net in the nasal mucosa. Second, air is humidified by nasal secretions. Third, air is filtrated and some gross particles are captured by the endoturbinates, to prevent tehir entrance into the larynx.\n\nThe accesory muscles expand (internal intercostal)or contract (external interconstal)the thoracic box like a pump. that´s the way they help .\n\nCarbon monoxide is very dangerous because it has several times more affinity with the hem group of hemoglobyn than oxygen. So, in an environment rich in carbon monoxide, when inspirated it binds to hemoglopbyn, displacing oxygen molecules from the Hem group and  preventing them to reach the organs, causing tissue anoxia and sometimes death. Treatment involves oxygen therapy, and sometimes a hyperbaric chamber( a place with high concentrations of oxygen in the air, and at a higher atmospheric pressure).

The skin is one of the major organs. Cilia in the nose prevents inhalation, the normal bacteria in the body that live there, white blood cells in the bloodstream, eyelashes and tears in the eyes, etc, etc. Our bodies come with self-healing structures unless they are pushed beyond their limits and can no longer function properly.

The Respiratory tract is vulnerable to dessication.\nTo prevent dessication, air is naturally "warmed" by the upper respiratory tract before it enters the lower tract.\nDuring winter, the air is colder may not be sufficiently "warmed".\nThis dessicates the respiratory tract lining causing it to crack.\nThese tiny cracks allow foreign bacteria and viruses to enter and cause infection or inflammation.

Respiration is performed using tracheae, air-filled tubes which open at the surfaces of the thorax and abdomen through pairs of spiracles. The spiracle valves only open to allow oxygen and carbon dioxide exchange. The tracheoles, found at the end of the tracheal tubes, are insinuated between cells and carry oxygen throughout the body.

A few things I can think of right off my head, without reviewing physiology.  Very basic info here, for more details, you can find it in any good physiology textbook.\n\nSmoke in cigarrettes decreases the capacity for hemoglobin to carry O2, and thus decreases the efficiency for O2 diffusion.\n\nCO2 decreases the surfactant in the lungs, making them less efficient in CO2/O2 exchange.\n\nCO2 also damages cells lining the blood vessels (capillaries) that are important in the diffusion process.
