How Much Oxygen to Give a Patient

Oxygen is the most commonly used drug in emergency medicine, and when used judiciously in treating hypoxemia, it undoubtedly saves a life. But unfortunately, oxygen is often misused, and the dangers of over-oxygenation are unappreciated How Much Oxygen cylinder bd to Give a Patient.

In 2008, the British Thoracic Society produced the first formal guidance on emergency oxygen use. The guideline is objective, evidence-based, and peer-reviewed.

Advocating safe use of oxygen by encouraging target saturation levels to be prescribed for each patient, based on what is believed to be safe and regular or near-normal. A target saturation range of 94–98% is advised in most patients.

The importance of recognizing patients at risk of type 2 respiratory failure is highlighted, and, in such patients, a target saturation range of 88–92% is recommended.

Oxygen Therapy

Oxygen therapy is the administration of oxygen at concentrations more significant than that in ambient air (20.9%) with the intent of treating or preventing the symptoms and manifestations of hypoxia, which includes agitation, personality change, headache, nausea, increase in pulse, increase frequency or Sob, cyanosis.

How to assess the need for oxygen therapy

Patients need oxygen therapy based on specific clinical conditions. Examples include post-operative patients, shock, trauma, acute myocardial infarction, or cyanide poisoning. How Much Oxygen to Give a Patient

Lab measures to document hypoxia 

It includes invasive and non-invasive methods such as hemoglobin saturation, arterial blood gas analysis, and pulse oximetry.

Oxygen Delivering Systems

  1. High flow system

The gas flow of a device that is adequate to meet all inspiratory requirements. By providing the complete Insp. Volume, the high flow system delivers its FiO2 very accurately. High-flow systems can deliver both high and low concentrations of O2. It includes: venturi mask, venturi type nebulizers (Fail > .50 FiO2), high flow blender system. Gas injection nebulizer (GIN) -works for all FiO2s.

  1. Low flow system

It is the one through which O2 is delivered to supplement the patient’s tidal volume. It includes a cannula, simple mask, reservoir, or non-rebreather (highest FiO2).

Is there a typical amount of oxygen therapy?

Your healthcare team will monitor your oxygen needs while on oxygen therapy. They may adjust the dose or rate to make sure you get the amount that’s right for you.

The amount of oxygen differs for each person and is based on how well your lungs work.

Oxygen equipment safety

  • Be careful with portable oxygen tanks – don’t drop, drag, or roll them.
  • Don’t adjust the knobs or valves on the wall above your hospital bed or portable oxygen tank. This can:
  • change your dose, and you may get too much or too little oxygen therapy
  • increase the risk of damage to the portable oxygen tank (some types of damage can be dangerous)

ARE OXYGEN CONCENTRATORS ENOUGH?

A typical oxygen cylinder lasts about four hours for patients requiring HFNC support. Despite oxygen supply shortages, there are extended outside oxygen refilling centers in several states.

This has pushed the demand for oxygen concentrators very high. There is an acute scarcity of oxygen concentrators, and reports of black-marketing of the machine are standard. Oxygen concentrators use environmental oxygen to produce concentrated or purified oxygen to be inhaled using a cannula.
