What is a normal oxygen level on a gas monitor? ›

OXYGEN GAS SENSOR ALARMS

Normal oxygen levels range between 19.5% and 23% (normal 20.8%). Serious health effects, fires or death by asphyxiation can occur quickly when oxygen levels are unsafe (below 16% or above 21%).

Accurate oxygen (O2) measurements are essential to prevent injuries or deaths in situations with potentially high or low levels of oxygen. O2 gas detectors will typically trigger an alarm when the oxygen level drops below 19.5 percent volume.

An oxygen analyzer is used to measure trace or percent levels of oxygen concentration in gas streams or the surrounding atmosphere.

Oxygen deficiency monitors will go into alarm mode at readings below 19.5%. This enables audible/visual alarms to indicate to personnel that an action needs to be taken prior to injury. Humans will not detect ill effects for short duration exposures until oxygen levels reach 14-16 %, but caution is required.

People should contact a health care provider if their oxygen saturation readings drop below 92%, as it may be a sign of hypoxia, a condition in which not enough oxygen reaches the body's tissues. If blood oxygen saturation levels fall to 88% or lower, seek immediate medical attention, says Dr. Lutchmansingh.

4) What is the typical measuring range for an Oxygen Analyser? The analyzer is capable of measuring from zero to 100% oxygen in the gas phase.

Ultrasonic oxygen sensors use sound speed to measure the amount of oxygen in a gas or liquid sample. In liquid, upstream and downstream sensors measure the velocity difference between high-frequency sound waves. The change in velocity is proportional to the amount of oxygen in the sample.

Do not allow the instrument to draw liquid through the tube and into the meter. 7. Readings must be above 19.5% O2 and below 23.5% O2, 10% LEL, 25 ppm CO, and 10 ppm H2S for legal entry into a space.

For most people, a normal pulse oximeter reading for your oxygen saturation level is between 95% and 100%. If you have a lung disease such as COPD or pneumonia, your normal oxygen saturation level may be lower. Your healthcare provider will let you know what levels are acceptable.

A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The time taken for the voltage to change from 0.1 V to 1.0 V (referred to as the lean to rich response time) should be about 300 milliseconds.

Normal Results

Values at sea level: Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mm Hg), or 10.5 to 13.5 kilopascal (kPa) Partial pressure of carbon dioxide (PaCO2): 38 to 42 mm Hg (5.1 to 5.6 kPa) Arterial blood pH: 7.38 to 7.42.

Low oxygen level, also called hypoxemia, is considered a reading between 90% and 92%. A reading this low means you might need supplemental oxygen or that there may be challenges that affect how your lungs function. A result below 90% indicates that you should seek medical attention.
