Understanding Your Oxygen Prescription

An oxygen prescription is a written directive from a physician detailing the kind of oxygen therapy to be used and the quantity of additional oxygen the patient needs. A medical procedure called oxygen therapy gives the body extra oxygen to aid with respiratory issues brought on by various medical problems. When a person’s oxygen requirements cannot be satisfied by breathing regular air, supplemental oxygen is utilized, which can enhance their quality of life and general health.

Understanding your oxygen prescription is crucial because it guarantees the appropriate amount of oxygen to satisfy your needs and prevent issues. The flow rate, duration, and frequency of oxygen therapy, as well as any other instructions or safety considerations, may all be included in your prescription.

Flow Rate

  • The flow rate describes how much extra oxygen you require each minute. Liters per minute are used to measure it (LPM). Your specific demands and condition will determine the flow rate that is recommended for you. You could need a more significant flow rate than someone with mild respiratory distress if you have severe distress.


  • The duration is how long you must utilize supplementary oxygen each day. Typically, it is expressed in daily hours (HOD). Your specific demands and conditions will determine the time recommended for you. You might need to stay longer than someone with mild respiratory distress if you have severe respiratory distress.


  • The frequency describes how frequently you require extra oxygen each day. The standard unit of measurement is sessions per day (SPD). Your specific demands and condition will determine the frequency that is recommended for you. You could need more frequent sessions if your condition is severe compared to someone with minor respiratory distress.

Special Instructions or Precautions

Your prescription may also include particular directions or precautions tailored to your health or circumstance. For instance, your prescription may specify how to utilize your oxygen therapy during exercise or physical activity if you have chronic obstructive pulmonary disease (COPD). Your medication may determine how to use your oxygen therapy while you sleep if you have sleep apnea.

Following Your Prescription

Suppose you have any questions or concerns regarding your oxygen therapy. In that case, you must follow your prescription and inform your doctor. If you don’t take your medication as told, you could experience side effects like hypoxemia (low blood oxygen levels), hypercapnia (high blood carbon dioxide levels), or even death.

Speak with your practitioner if you are having problems following your prescription. To better suit your needs, they might be able to modify the flow rate, duration, or frequency of your oxygen therapy. They could offer further help and resources, such as therapy or instruction.

Deciding Which Oxygen Delivery Device is Right for You

Selecting the appropriate oxygen delivery system is essential for people who need medical-grade oxygen to manage their medical conditions. The involvement of healthcare professionals in assisting patients in choosing the best oxygen delivery system for their particular needs is crucial. Medical-grade oxygen can be given in several ways, including liquid oxygen systems, compressed gas cylinders, and portable oxygen concentrators.

Compressed Gas Cylinders

Patients who employ different types of delivery systems yet want a dependable source of supplementary oxygen frequently uses compressed gas cylinders as a fallback alternative.

Liquid Oxygen Systems

An additional method for delivering medical-grade oxygen is through liquid oxygen systems. These systems keep liquid oxygen in reservoirs that can be topped off at home or by a licensed service provider. Patients requiring higher flow rates of supplementary oxygen than portable concentrators or compressed gas cylinders can frequently use liquid oxygen devices.

Medicaid Coverage

Medicaid-eligible patients might have few options, but they should still talk to their doctor about their particular requirements to discover the best solution. It’s vital to check with the provider for options because Medicaid typically only covers specific equipment and services.

Patient Needs

The patient’s specific demands and the advice of their healthcare physician should ultimately guide the selection of the oxygen delivery device. The best option will rely on several variables, including the patient’s lifestyle, degree of exercise, and health. A patient who must get a high flow rate of supplementary oxygen may need a liquid oxygen system. In contrast, a patient on the go may benefit from a portable oxygen concentrator.

Patients must be upfront with their healthcare professionals about their specific requirements and preferences. Patients can get assistance from healthcare professionals in navigating the different alternatives and selecting the best gadget for their needs.

AC Power Supply and External Battery Charger for Inogen One G System

The Inogen One G system is a portable oxygen concentrator that provides oxygen therapy to patients with respiratory problems.
