Understanding Oxygen Devices and Delivery Systems
Advancements in respiratory care have led to a range of oxygen devices and delivery systems now available in the healthcare market. Their usage was initially confined to inpatient environments but, today, are extensively used in outpatient settings as well. Particularly for patients with chronic pulmonary diseases and complications of hypoxaemia. Understanding each device's features and functionality will aid in tailoring patient-based solutions for oxygen therapy.
Oxygen Use: From Inpatient to Outpatient Settings
Chronic lung ailments often necessitate long-term oxygen therapy, with the goal being to ensure the right amount of oxygen reaches the lungs. Notably, studies indicate that women tend to have higher occurrences of long-term oxygen therapy due to their high numbers in middle-aged smokers.
Understanding Oxygen Concentrators
These devices, also known as oxygen generators, essentially filter and enhance room air. It removes particulates and much of the nitrogen, producing a high-oxygen flow that can be continuously delivered to the patient. There are two primary types of oxygen concentrators: stationary and portable. They support flow rates up to 10 to 15 litres per minute and 2 litres per minute respectively.
Differences between Stationary and Portable Oxygen Concentrators
Although both types perform the same function, the choice of a stationary or portable concentrator hinges on several factors: oxygen output, size, weight, power options, and price. Because of their mobility, portable oxygen concentrators are most suitable for active patients frequently away from AC power sources.
Drawbacks of Oxygen Concentrators
As effective as oxygen concentrators are, an inherent disadvantage is their dependence on electrical power. It thus necessitates backup arrangements in case of power outages. Patients using stationary concentrators also have to account for factors like regular servicing, noise, and vibration.
Understanding Compressed Gas Cylinders
Compressed gas cylinders, although less preferred compared to oxygen concentrators, can still offer patient-tailored solutions. On the downside, due to their size and weight, their portability can be an issue that may necessitate the use of trolleys, wheel carts, or backpacks.
Exploring Liquid Oxygen
Liquid oxygen systems are highly convenient. This system brings two main factors into play when choosing an oxygen supply: convenience and efficiency. With the oxygen lasting longer, more straightforward filling process, and lighter portability, it's an option that might appeal to many patients.
Oxygen delivery systems: Low-flow vs. High-flow
Delivery systems for oxygen are split into two main categories: low-flow and high-flow. The classification is based on how much oxygen it provides - enough for a patient's peak inspiratory flow or less. Understanding these systems will further aid healthcare providers in providing suitable solutions for their patients.
