What is the flow factor for 70/30 Heliox?
Flow Meters 5 The heliox correction factors are generally rounded off to 1.4 for 60:40, 1.6 for 70:30, and 1.8 for 80:20.
How is Heliox flow calculated?
When using Heliox, how would you calculate the actual Heliox flow from the observed O2 flow on the flowmeter (10 L/min)? Observed flow on flow meter (10 L/min) X factor (1.8) = 18L/min of actual Heliox flow.
Why is Heliox used in diving?
An appropriate mixture of helium and oxygen for saturation diving. Saturation divers need mixtures of helium and oxygen (Heliox) to breathe and work at depths – usually up to more than 200 feet below sea level for longer periods of time. Synthetic air can be used for recreational scuba diving.
What does 70/30 Heliox mean?
Heliox 70/30 is a supportive respiratory therapy treatment in upper airway obstruction, used when hypoxemia is present or when trauma to the airway occurs. Our Heliox 70/30 Health Canada approved blend (DIN 02416468) consists of 70% helium and 30% oxygen.
How long will a heliox H tank last?
For example, a respiratory therapist wants to make sure the patient on heliox (H cylinder) running at 10 LPM will not run out of gas over the change of shift. The gauge reads 600 PSI. Entering these data and hitting Calculate Duration yields a duration of 126 minutes….Oxygen Tank Duration.

What is heliox gas?
Heliox is a helium–oxygen gas mixture that reduces work of breathing by decreasing airway resistance by decreasing turbulent flow and thereby decreasing airway resistance. From: Handbook of Supportive and Palliative Radiation Oncology, 2017.
How do you administer heliox?
Heliox can be administered via a well-fitting face mask at flows high enough to prevent entrainment of room air. The effectiveness of heliox in reducing the density of administered gas and improving laminar airflow depends on the helium concentration of the gas.
What is heliox made of?
Heliox, a mixture of helium and oxygen, has a density that is less than that of air.
How long will an H tank last on 2 LPM?
When full, it contains enough oxygen to supply a person using a flow rate of 2 liters per minute for about 4 hours.
How long will h cylinder last?
For example, a respiratory therapist wants to make sure the patient on heliox (H cylinder) running at 10 LPM will not run out of gas over the change of shift. The gauge reads 600 PSI. Entering these data and hitting Calculate Duration yields a duration of 126 minutes….Oxygen Tank Duration.

What do you administer Heliox for?
Heliox, a helium-oxygen gas mixture, has been used for many decades to treat obstructive pulmonary disease. The lower density and higher viscosity of heliox relative to nitrogen-oxygen mixtures can significantly reduce airway resistance when an anatomic upper air-flow obstruction is present and gas flow is turbulent.
What do you administer heliox for?
Which is better for a scuba tank helium or nitrox?
And since it has a lower percentage of oxygen than nitrox, the risk of toxicity is also reduced. On the downside, the thermal conductivity of helium is six terms higher than that of nitrogen. This means that a diver using Heliox will lose heat faster than the one breathing Nitrox or air.
Is the gas in a scuba tank oxygen?
Many divers incorrectly call the gas in their scuba tank oxygen. Some even call the gas cylinder ‘oxygen tank’. While that statement is not entirely correct, it does have some truth in it. Yes, oxygen is one of the gases you will find in a scuba tank.
What are the conversion factors for an oxygen tank?
Oxygen Cylinder Conversion Factors • D Tank = 0.16 • E Tank = 0.28 • G Tank = 2.41
What kind of gas is nitrox in diving?
Nitrox is a gas mixture of oxygen and nitrogen, but with a higher oxygen percentage than found in ordinary air. As a result of its higher oxygen concentration, the percentage of nitrogen in nitrox is always lower than in air. There are two standard mixtures of Nitrox recognized by NOAA for diving: Nitrox I and Nitrox II (see Table 1).
