2l/m ideally, up to 4/5 can be given but not for long as it dries and burns nostrils

What happens to the breathing rate if blood concentration of oxygen decreases?
Decreased breathing rate > more Co2 and less O2 in blood > more acidity > Lower PH level
How wiil you describe the sequence of oxygen carbon dioxide and blood flow?
Blood flows in a circle from lungs to tissues and back. At the lungs O2 gets into the blood and CO2 gets out - at the tissues O2 leaves the blood and CO2 enters.
Which is most stable in the followings O22 or O2 plus or O2 or O2?
The most stable element chosen from the group of O22-, O2+ (plus), O2, or O2- is O2. This is because O2 is a very stable form of oxygenated ozone that is in the least danger of being depleted.
How many moles in 150.0 g O2?
150.0 g O2 x 1 mole O2/32 g O2 = 4.688 moles O2
What are the products of a non-cyclic electron flow?
In photosynthesis, the noncyclic electron flow produces enzymes called cytochrome b6f complex. Its function is to catalyze the electron transfer of plastoquinol to plastocyanin.
What percentage of oxygen is delivered by a 5 liter nasal cannula and a 50 percent venturi mask when used together?
Why would you need to do that anyway? If you need the concentrated O2 that a mask provides, then a nasal cannula is not affective.
Can a nasal cannula be used on trauma patients?
You could unless maxfax trauma is present. You wouldn't use nasal cannulae in trauma patients as well, you would probably give 15L/min O2 via a non-rebreather mask until stabilised, sats aim for 94-98%. (British Thoracic Society guidelines)
What is the normal oxygen concentration of a man?
A normal O2 Sat on room air is 96-100% . When a patient is on O2 by nasal cannula, the Sat level will of course be higher due to O2 is continuous @ 2 liters/NC. Some patients with high anxiety will demand the need for O2 when Sat level on room air is 97%. It always depends on the individual person, because some people may not be short of breath @95% O2 Sat on room air. Again, those with COPD must be assessed very freq, because they should only recv up to O2 2L/NC on a cont flow. The same patient may recv an MD order for PRN O2 ie: O2 2L/NC if Sat< 96% on RA @ night only. Look up online re: COPD and the reasons for recv only a certain amt of O2 everyday.
What is the highest liter of o2 that should be administered by nasal canula?
10
What is the maximum O2 for nasal cannula?
The delivery of external oxygen (O2) depends on the condition. To prevent shock, O2 is often set high, such as 8 L /min. (liters per min). But, in someone with emphysema, for example, anything higher than 2 L/min can kill because the brain reacts differently to CO2 in the lungs in emphysema (reverse feedback than normal... normally we breathe in response to higher Co2 levels, triggering us to exhale and inhale).
Two ways to increase oxygenation to the myocardium?
nitroglicerin and providing nasal O2
Proper o2 flow for a non-rebreather mask?
A nonrebreather mask (NRB) should have an oxygen flow rate of at least 10 liters per minute in order to deliver the maximum oxygen concentration.
What are the effects of exercise on peak flow rate?
yes it does in many ways such as Exercise will effect your breathing and your heart rate by making them both faster. It does this because you need more oxygen to your muscles so you are breathing faster to get in more o2 and your heart beats faster to circulate that o2 to the muscles in your body.
When blood o2 decreases what happens to respiratory rate?
It will increase.
Examples of a sensor in a car?
Mass air flow sensor, O2 sensor
How do you calculate heat rate in gas power plant?
E=MC2 + o2 + H20 = Heat rate
How does O2 and nutrients enter the cells?
Through blood flow. O2 and other gases enter the cell by inspiration. there is some reactions that occurs in the lung. O2 is given to blood cells. there is a special pigment that is specialized for o2 captuing.it is a homeoglobin.So o2 transported to cells by this pigment.
