Your Oxygen Prescription If you require oxygen therapy, your doctor will prescribe you a given oxygen flow rate such as 2 liters per minute. An oxygen flow rate of 2 LPM means the patient will have 2 liters of oxygen flowing into their nostrils over a period of 1 minute.
The portable O2 tank you grabbed has 500 psi left in it. Do you have enough oxygen left for the trip? See the example below At 500 psi with a flow rate of 6 liters per min, there are 28 minutes of oxygen left.
Without oxygen at 6 L/min, your patient's O2 saturation on room air drops to 75%. It will take you 10 minutes to get there and back. The portable O2 tank you grabbed has 500 psi left in it. Do you have enough oxygen left for the trip?
Oxygen prescriptions generally run from 1 liter per minute to 10 liters per minute with 70% of those patients being prescribed 2 liters or less. Continuous flow oxygen always flows from the cannula and never stops until the unit is turned off.
Easy to use online calculator and mobile App for oxygen cylinder duration estimation. The free calculator & app is ideal for technicians, therapists, patients and caregivers to easily calculate the approximate available oxygen remaining in an oxygen cylinder, based on the patient’s device and cylinders size & contents.
Adjustable settings for a precise readout. Simply input your device type (Conserver or Regulator), Liter Flow Setting, Cylinder Size and Approximate Fill Level to calculate the approximate cylinder duration.

A pulse ox works like this; when you place the probe on your finger, the top of the probe contains a transmitter that emits a beam of light that penetrates through the finger. That beam of light is then absorbed by the hemoglobin in the blood cells as they pass through the the tiny blood vessels in your finger.
The more “saturated” the hemoglobin is, the brighter red the blood becomes. When the Oxygen saturation of the hemoglobin is low, ( usually below 75%), the blood actually gets darker…almost black in color (such as the blood that’s carried in your veins).
What this means, is that you can suffer a pretty nasty asthma flare and initially have normal or near normal O2 sats. Significant desaturations usually don’t usually occur in asthmatics unless the person is extremely ill, has a secondary lung problem or has a pneumonia brewing.
PCO2 ( carbon dioxide in your blood) is actually more of a concern than O2 saturation when you have an obstructive disease like asthma. We’ll talk about PCO2 the next time around. Post navigation. The OTHER Breathinsteven. Stress Break Stephen Style.
The brain only has the ability to survive for up to 4 minutes if oxygen gets completely cut off.
One of the most popular questions which people have is how low can their oxygen level go before they die. There are various reasons behind asking the question. One of the reasons is before going mountain climbing or even swimming. An understanding of how low a person’s oxygen level can go will allow them to make the right decisions ...
It is probably due to the oxygen levels dropping in the night. Sleep apnea is the cause of this or any other respiratory disorder such as UARS.
Low oxygen level indicates that the treatment you are undergoing for sleep apnea isn’t effective. Low oxygen levels in the blood are something that patients with sleep apnea suffer from. A normal blood oxygen level should be anywhere between 94 percent and 98 percent. Oxygen level drops to 80 percent or less due to not breathing for 30 seconds ...
How does Oxygen Levels Due to Sleep Apnea Impact the Body? 1 Fluid buildup in your body 2 Heart rhythm problem 3 Stroke 4 Heart Failure 5 Increasing pressure on your heart’s right side
It is important to follow up with the sleep study to ensure that the right actions are taken. Your short term memory and other cognitive functions would be damaged, as well as a heart attack and stroke in your sleep would occur with a continued drop in oxygen levels.
The normal oxygen level is 21% but by adding extra oxygen, they can increase the amount of oxygen your lung full contains, thereby increasing the amount of oxygen that gets into the body. The oxygen level can be pushed higher than the normal 21%, all the way up to pure oxygen (100%).
From that equation you will note that when the the SaO2 drops there is compensatory increases in Hb ( Haemoglobin ) and Cardiac Output to try and maintain oxygen delivery to tissues. Quite often people with Hypoxia are Polycythemic and they have increased Cardiac Outputs to increase or maintain Oxygen delivery.
Usually, these kinds of oxygen levels are seen in confined spaces or industrial applications; something external to the body is causing the amount of oxygen in the air to be low (CO2, CO, pure nitrogen, etc). More frequently, hypoxia is caused by injury/illness, or by altitude.
When oxygen saturation levels fall below the lower 80’s, organ function begins to suffer, and there is potential injury to the brain, heart, and other organs. The danger of cardiac arrest (the heart stopping) is increased when oxygen saturation is quite low. Ment. Continue Reading.
Home oxygen is given to patients mainly to improve Oxygenation and to alleviate the increases in Pulmonary artery pressures so the right heart can struggle less against an increase in afterload of the right ventricle ie increased pulmonary vascular resistance from pulmonary hypertension.
(Having high levels of CO2 in the blood is called hypercapnia. )
Since the damage is a grey-area, my answer has to be kinda 'grey' as well. sorry. Steven L. Gaudry.
The natural air we breathe contains 21% oxygen (21% FiO2) and 79% nitrogen at all times (with some trace gases). The FiO2 coming from a portable oxygen concentrator can vary anywhere from 90–96% FiO2. Hospital-grade oxygen found in a medical facility can reach >99% FiO2.
Those factors include breath size (how large or small a breath is), breath rate (how fast or slow you are breathing), and inspiratory flow rate (which is affected by both breath size and breath rate).
