How To Estimate Oxygen Consumption For A Hospital?

May 11, 2022

There are several methods for purifying oxygen from the atmosphere. A separator membrane is the simplest technique to manufacture small amounts of practically pure oxygen. The air is compressed and forced across the membrane, which allows the smaller oxygen molecules to pass but not the bigger CO2, M2, and Ar molecules and atoms.

However, most hospitals do not adopt this strategy for two reasons. It uses a lot of energy, so if the hospital lost power, it wouldn't be able to run much oxygen on its generator. The second reason is that the oxygen concentrators are noisy and emit a lot of heat when the compressor is running. Hospitals contain a lot of thermal load, therefore adding a kilowatt of thermal load to every oxygen patient would almost certainly necessitate a major revamp of the HVAC system.

Instead, oxygen is produced in an industrial gas facility offsite. The most abundant gases in the atmosphere are oxygen, nitrogen, and argon, which have common industrial applications. There, air is compressed and cooled using special refrigerators (often helium blocks) until it liquefies.

Once the components have liquefied, they divide into layers similar to oil and water, which are fed through insulated pipes into massive vacuum flasks known as dewars. Many small enterprises, farms, and offices have a tiny dewar for liquid nitrogen used for medical/veterinary operations or machine repair, hence this is clinical chevalier.

To keep up with the demand for oxygen, hospitals began performing laborious computations to determine the remaining capacity. This method has the potential to be imprecise and error-prone. To address this problem, many hospitals have begun to use flow meters to measure oxygen levels. Flow measurements can provide real-time, accurate data, allowing the facility to operate at full capacity during the epidemic. Another issue was the increased need for liquid oxygen, which might cause the evaporators to become clogged. Accurate monitoring ensures that demand never exceeds system capacity, resulting in breakdowns.

The National Health Service in the United Kingdom wanted to equip hospitals with flow meters for the primary oxygen supply so that emergency response capacity could be assessed. The system now relies on pressure from cryogenic oxygen tanks. This method sends a notification to the supplier so that supply can be scheduled. With the COVID-19 epidemic, oxygen demand soared dramatically, causing a threat of shortages. The hospitals now have a better understanding of the oxygen capacity and the rate at which supplies are required. They can also create a good backup plan based on the information provided. Estate managers are notified the moment a threshold is exceeded, giving them peace of mind and allowing them to focus on other matters.

How To Estimate Oxygen Consumption For A Hospital?

The following equation represents total O2 content:

? [SaO2 x Hgb x 1.31 ml/dl blood] + ([0.003 ml/dl blood per mmHg x PO2]) = CaO2.

where Hgb represents hemoglobin concentration and SaO2 represents hemoglobin saturation at the specified PO2.

Both respiratory and circulatory function are required for oxygen transport. The result of arterial O2 content and cardiac output is total O2 delivery (DO2) to tissues (QT).

CaO2 x QT = DO2

It's worth noting that arterial O2 content is influenced by both PaO2 and hemoglobin concentration. As a result, low PaO2, low hemoglobin concentration, or insufficient cardiac output may cause O2 delivery problems.

The link between O2 consumption, O2 content, and cardiac output is expressed by the Fick equation:

VO2 = QT x (CaO2 - CvO2) = O2 consumption


Curve Of Oxyhemoglobin Dissociation

As a result, the arteriovenous difference is an excellent indicator of overall O2 delivery sufficiency. The typical arteriovenous difference is determined to be about 5 ml O2/dl blood with a normal O2 consumption of roughly 250 ml/min and a cardiac output of 5000 ml/min. Because the usual extraction ratio is around 25%, the body only utilizes around 25% of the oxygen carried by hemoglobin. When demand for oxygen exceeds supply, the extraction fraction rises beyond 25%, and when supply exceeds demand, the extraction fraction falls below 25%.

Because of enhanced O2 extraction when DO2 (oxygen supply) is considerably lowered, VO2 normally remains normal (meaning mixed venous O2 saturation decreases). Further reductions in DO2 reach a tipping point beyond which VO2 becomes exactly proportional to DO2. This supply-dependent O2 condition is usually connected with lactic acidosis that develops as a result of cellular hypoxia.

Remember the oxygen-hemoglobin dissociation curve: a rightward shift (raising P50) decreases O2 affinity, displaces O2 from hemoglobin, and increases O2 availability in tissues. A shift to the left (lower P50) increases hemoglobin's affinity for oxygen, lowering its availability to tissues. In adults, the normal P50 is 26.6 mmHg.
