Oxygen therapy
with liquid oxygen
Oxygen therapy with medicinal liquid oxygen is an advanced and effective solution for patients with respiratory problems. It offers a highly efficient way to ensure a continuous supply of oxygen.
This method stands out for its adaptability and ease of use, which makes it a preferred option for those who need to maintain constant oxygenation.
It is supplied in fixed and mobile cryogenic containers to adapt to the patient's needs at all times. The fixed tank has a capacity of 32 liters of liquid oxygen (equivalent to 27,000 liters in gas state) at a very low temperature (-183ºC).
It can be used to fill the portable oxygen backpack (capacity of 1.2 liters of liquid oxygen), which weighs little, is small and has autonomy for a few hours depending on the prescribed flow. It must be taken into account that liquid oxygen, if not used, evaporates.
Key Benefits of Liquid Oxygen Oxygen Therapy
- Compact and portable: the portable oxygen backpack allows for greater mobility, as its lightweight design facilitates transport, ideal for those looking to maintain an active life.
- Extended duration: liquid oxygen, being stored at high density, provides a longer supply compared to traditional compressed oxygen systems.
- Stable and personalized flow: they offer a constant and adjustable flow, and it adapts to the respiratory needs of each patient, both at rest and during activity.
- Improved quality of life: by ensuring optimal levels of oxygen in the blood, this treatment relieves dyspnea, increases energy and reduces fatigue, and promotes better general well-being.
Main applications
- Chronic respiratory diseases: such as COPD, pulmonary fibrosis and severe asthma.
- Post-COVID-19 rehabilitation.
- Respiratory failure.
- Lung transplant recipient patients.
How to use a liquid oxygen flask
Connect the tube on the nasal cannula or mask to the oxygen outlet on the flask.
Insert the nasal cannula or put on the mask.
Adjust the flow rate by turning the knob until reaching the value prescribed by the doctor.
How to fill a liquid oxygen flask
Make sure the flow rate knob is at zero.
Connect the flask to the tank by pressing down.
Pull down the lever on the flask and hold it there until you hear the alert sound due to the gas escaping, which indicates that the flask is full. The flask will take a minute to fill up.
You will know when it is full because a dense white vapour will come out of the bottom.
Once the flask is full, return the lever to the upright position. Remove the flask from the tank while pressing the release button on the tank.
If removing the flask is difficult, do not force it. Wait a few minutes and try again.
If any liquid oxygen is leaking, connect the flask to the tank again, wait a few minutes, then try separating the units again. If there is still a leak, connect them again and contact the technical team. If they cannot be connected, make sure the room is well-ventilated.
How long liquid oxygen tanks last
| Flow rate | How long the tank lasts (approx. number of days) | How long the flask lasts (approx. number of hours) |
|---|---|---|
| 0,5 l/min | 36,16 h | 25 h |
| 1 l/min | 18,06 h | 16 h |
| 1,5 l/min | 12,05 h | 10,70 h |
| 2 l/min | 9,04 h | 8 h |
| 2,5 l/min | 7,23 h | 6,40 h |
| 3 l/min | 6,03 h | 5,30 h |
| 4 l/min | 4,52 h | 4 h |
| 5 l/min | 3,62 h | 3,20 h |
The times calculated in this table may vary and are based on the following conditions: room temperature of 20°C, well-maintained equipment in good condition, normal evaporation rate (NER) within the limits indicated by the manufacturer, and proper filling in a fixed position without any movement. In any other conditions, the indicated data and results may vary.
