in a human ventilator how much percentage of oxygen is given?
363965
It depends on the ventilator.  Some ventilators can only deliver 100% FiO2 (fraction of inspired oxygen). Other ventilators have a dial for selecting the FiO2.  On those, you can choose just about any % you want, and the % you select will depend on the patient's condition.

oxygen is removed and replaced by co2

Your depth of breathing and rate of breathing is adjusted by your body to keep your arterial blood oxygen saturation level about 95+% (this can be checked with a simple oximeter) and the arterial carbon dioxide at 40 mm Hg (this usually requires an arterial blood sample to check).

Many oxygen bars use a concentrator, which filters out the nitrogen and other gases in the air circulating in the room, and then delivers the concentrated oxygen, about 95 percent pure, through a hose at a continuous flow rate. But oxygen users inhale the surrounding air along with the oxygen pumped through the nose hose, which decreases the concentration. The concentration is further decreased when oxygen is pumped through an aroma. According to one oxygen bar supplier, the customer gets less than 50 percent pure oxygen.\n\nFor further reading please visit: -

CO2 is carried through the blood in the body to the lungs to be exhalated.

The answer is D. oxygen\n\n"Oxygen is given with a small amount of continuous positive airway pressure ("CPAP"), and intravenous fluids are administered to stabilize the blood sugar, blood salts, and blood pressure. If the baby's condition worsens, an endotracheal tube (breathing tube) is inserted into the trachea and intermittent breaths are given by a mechanical device."

There are two oxygen carrying mechanisms in the blood. One is dissolved oxygen in the plasma. The other is hemoglobin, the red colored stuff in the red blood cells. It combines with oxygen in the lungs, and releases it in the tissues, where it picks up CO2. CO2 also dissolves in the plasma, and both tend to give it up in the lungs. \n\nSaturation is a measure of how much oxygen is in the blood sampled as compared to the maximum possible. In hospitals, it is non-invasively measured by optical sensing through a finger tip. It's that little glowing clamp thing they stick on a finger. \n\nThis works because oxygen carrying hemoglobin is 'redder' than non-oxygen carrying hemoglobin. But it doesn't include the oxygen carried by the plasma, since plasma with oxygen isn't noticeably different in color than plasma with less oxygen in it. So this measurement isn't (quite) accurate since it's not really measuring all the oxygen present. \n\nBut this is clinically useful because it's a reasonable measure of what's really the point of bothering with oxygen saturation at all. some lung conditions interfere with the transfer of oxygen and CO2 in the lungs. Since the hemoglobin saturation participates in that transfer, how well it's been saturated can be used for practical clinical indications. We don't really need to know exactly what the oxygen saturation is, since, if it's good enough, that's all we need to know. Only if there's some major problem, will we need to know anything more detailed.

respiration..\n\nco2 is given off, it goes through our blood stream, reabsorbed by the alveoli, switched out with o2 by respiration

oxygen helps in breathing of the million cells in your body.Blood transfers oxygen to the cells & the cells can carry out their processes with help of oxygen.Since everything requires energy to carry on its processes,human require oxygen to carry out its process of living

Normal air is composed of about 78% nitrogen, 21% oxygen, .93% argon, and around .03-.05% carbon dioxide, among other gases.\n\nGood luck!

There are way too many variables for anyone to be able to give you a good answer from the information you gave. I'm an RT & take care of patients on ventilators in the ICU. If you have specific questions, and can share more info, you can email me & I'll try to answer them for you.

I don't understand your question. Tidal volume is measured using a respirometer. I'm not familiar with the other term.

most of the carbon dioxide gas is transported as bicarbonate in blood.(about 70 %).around 20 % as carbamino compound and rest 10% is transported in dissolved physical form.

Every time you exhale, you breathe out most of the air you breathed in. While the air is in your lungs, oxygen travels from air to blood and CO2 from blood to air, in each case moving naturally to where it is less concentrated.\n\nHow long it takes the average oxygen molecule from being absorbed to being breathed out again as part of a carbon dioxide molecule is a really good question - I have no idea if anyone has even calculated it, but we can try.\n\nMost people pass out if their blood oxygen level drops below about 80% - and most people can hold their breath for maybe 4-5 minutes (the record is almost 9 minutes by Houdini, but that's someone trained and a bit freakish). That implies you use 20% of the oxygen in, say, 5 minutes - so it would take 25 minutes to use it all, if that were physically possible.\n\nBTW, I'm prettty sure it's 8-9 pints of blood. The normal O2 reading in arterial blood is around 10-13 kPa, but I'd have to admit I don't know how to convert that to a mass (or free volume) of oxygen.\n----\nOoh, here you go: arterial blood contains about 20ml of oxygen per 100cc. Your blood volume is about 5 litres, so that would mean your body contains rather less than a litre of oxygen (because not all of your blood is fully oxygenated).
