Oxygen administration is an important procedure that comes into action in the emergency room or ICU in light of respiratory distress. The primary goal of the oxygen therapy administration is to maintain ideal levels of tissue oxygenation and reduce cardiopulmonary work. This has also come into assistance for chronic cases where the cardiopulmonary disease is at an advanced stage. Hypoxemia, inconsistent blood circulation, and increased stress during breathing – they all call for implementing administration of oxygen through various delivery systems. From venturi mask to nasal cannula, there is a wide variety of oxygen delivery devices available. The factors that choose the delivery device to be implemented include patients’ prescribed limits of oxygen, reliability of the device as a solution, ease of application, and very importantly, patient’s comfort and acceptance of the same. Let’s have a look at the popular choices and their ideal usage:
Nasal Cannula, for Low-Flow Delivery The primary purpose of typical low-flow oxygen delivery is to provide supplemental oxygen that is less the patient’s total minute ventilation. The oxygen that reaches the respiratory system will be diluted with the surrounding air composition and as a result, oxygen delivery is less than anticipated. These systems are ideal for patients with a relatively stable respiratory pattern and require low oxygen percentage. Nasal cannulas are used by those requiring additional oxygen during operative and diagnostic procedures as well as for chronic home care. You can get a nasal cannula here. Transtracheal catheters and nasal catheters are two other popular forms of low-flow delivery systems, albeit they fall in the higher end of the low-flow delivery system.
Face Masks, for Reservoir Systems Such delivery systems incorporate a mechanism of storing oxygen during the respiratory process, such that the patient can comfortably draw from the oxygen reservoir the moment minute ventilation flow exceeds the flow of the oxygen delivery. Cannulas and masks are the most recommended forms of reservoir delivery systems. However, there are certain delivery systems that rely on laryngeal masks to assist with supplementary oxygen delivery in the patients’ recovery room. However, this is a very specific design with supporting equipment that should be implemented only in a professional environment. These are widely used in patients requiring chronic therapy and wish for a greater degree of mobility. These masks are also known for their significant financial savings for long-term usage.

Venturi Masks, for High-Flow, Controlled Delivery Such systems employ oxygen concentration at a flow equalling or exceeding the amount inhaled by the patient. Often an air-entrainment or a blending system such as a venturi mask is used. This mask mixes the oxygen content with the air in the surrounding, creating high-flow enriched oxygen. They are used for patients requiring a monitored dosage of oxygen supply. Clinicians and doctors buy venturi mask online and administer them in cases where there might be a significant chance of the patient’s hypoxic drive getting affected, or when their respiratory drive is inconsistent.
