Totally unreliable. Signal disappears for days at a time.
The o2 arena is in wales, Cardiff ok
The best network is ORANGE, because there is signal everywhere. T-MOBILE doesn't pick up signal anywhere. O2 is OK. So the best network is ORANGE.
The brain adjusts breathing rate in response to various factors, primarily the levels of carbon dioxide (CO2) and oxygen (O2) in the blood. Increased CO2 levels or decreased O2 levels signal the brain's respiratory centers to increase the breathing rate to enhance gas exchange and maintain homeostasis. Additionally, physical activity, emotional states, and environmental factors can also influence breathing adjustments. These responses help ensure that the body meets its metabolic demands efficiently.
Chemical factors, such as levels of carbon dioxide (CO2), oxygen (O2), and pH in the blood, significantly influence breathing patterns. Increased CO2 levels or decreased O2 levels stimulate chemoreceptors that signal the respiratory center in the brain to increase the rate and depth of breathing, enhancing gas exchange. Conversely, a rise in blood pH (alkalosis) may slow respiration, while a drop (acidosis) typically accelerates it. These adjustments help maintain homeostasis and ensure that the body's metabolic needs are met.
The O2 chart provides information about the levels of oxygen in a particular environment over time. This data can be used to analyze trends, identify patterns, and make predictions about oxygen levels in the future.
On a Lexus IS300, the O2 sensor signal can typically be found in the engine bay, connected to the exhaust system. The upstream O2 sensor is located in the exhaust manifold or just after it, while the downstream sensor is located after the catalytic converter. You can access the wiring harness connector for the O2 sensors by following the exhaust pipes and locating the sensors. For precise identification, consulting the vehicle's service manual is recommended.
Breathing, CO2 and O2
Yes & no in certain circumstances. As o2 sensors age, the signal they produce becomes lazy (doesn't fluctuate as much). A lazy signal is inaccurate & the PCM will adjust based on the lazy signal. The PCM doesn't know any better, it just adjust the air/fuel based on the signal from the O2 sensor. Now o2 sensors can go bad or just get worn out. A bad sensor will likely turn the check engine light on. A worn out one may be hindering gas mileage but not sufficient enough for the check engine light to come on. If you have over 120k miles with the original o2 sensor, then I'd suggest to change it. You may get an increase in mpg
Anaerobic respiration occurs only in the absence of O2. When O2 is present, aerobic processes take over; so it can be said that O2 'poisons' anaerobic biochemistry.
Chemoreceptors play a crucial role in regulating breathing by detecting changes in the levels of carbon dioxide (CO2), oxygen (O2), and pH in the blood. Central chemoreceptors, located in the brainstem, primarily respond to rising CO2 levels, which signal the body to increase the rate and depth of breathing. Peripheral chemoreceptors, found in the carotid and aortic bodies, monitor O2 levels and also contribute to the respiratory response. Together, these chemoreceptors help maintain homeostasis by ensuring adequate oxygen supply and efficient removal of carbon dioxide.
You can be unconcious and have a SaO2 of 100%.... but say your having difficultys breathing, if your O2 level drops below 94% Oxygen is needed, about 15% on a Nasal Canula. But if your passing out due to lack of O2, then it would have to be down around 85-90% but mind you.. that's not good. Plus, you cannot hold your breath and bring your O2 levels down. You will on the otherhand pass out if you hold your breath too long, not because your O2 levels are low, but because your body takes over so it can make itself breath again. Sometimes, your body can outsmart you.
More avalible light and heat so the rate of photosynthesis speeds up - releasing more o2.
