Pressure for Oxygen Therapy

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure for Oxygen Therapy

Patients short of breath may need an oxygen concentrator to provide sufficient oxygen to make their breathing easier. Underlying health issues that could require the extra oxygen or oxygen therapy include asthma, lung cancer, chronic obstructive pulmonary disease (COPD), the flu and, most recently, COVID-19. Without requiring oxygen stored in tanks or containers, oxygen concentrators provide a continuous supply of oxygen that comes from the surrounding air.

Modern oxygen concentrators delivering about five to 10 liters of the gas per minute, typically at about 93% purity, are designed for either stationary (home) or portable usage. While a home oxygen concentrator may weigh less than 20 pounds, many portable oxygen concentrator models weigh less than 5 pounds.

Oxygen Concentrator

The oxygen concentrator uses a pump to compress the oxygen, filters or sieves to separate out nitrogen and other impurities, and pressure reducers to provide low pressure oxygen for patients to breath. With varying pressures and flow rates, different pressure sensors can be used at various points in the system. Any of the sensors for portable units need to be both small and light weight making microelectromechanical systems (MEMS) sensors ideal for these applications.

The low differential pressure measurements for flow are typically only a few kPA. Essentially, any of All Sensors DLHR, DLVR, ELVR, ELV and MLV series products that have respiratory pressure ranges will work for O2 concentrators in these ultra-low pressure applications.

Pressure Sensors in Medical Applications

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure Sensors in Medical Applications

According to a recent market report from Mordor Intelligence, a market intelligence and advisory service, the medical sensors market was valued at USD 12.36 billion in 2019 and is expected to reach a value of USD 20.72 billion by 2025, increasing at a compound annual growth rate (CAGR) of 9.07% over the forecast period (2020 – 2025). The report identifies the significant role that pressure sensors play in medical sensor market. Specific pressure sensor applications include:

  • respiratory breathing circuits (nebulizers, spirometers, patient monitoring)
  • flow/pressure control (therapeutic hospital beds)
  • gas collection (hospital gas supply, oxygen concentrators)
  • sampling/gas flow (blood analysis, gas chromatography, analytical instrument sampling systems)

A specific example of a home health system is continuous positive airway pressure (CPAP) respiratory therapy equipment that can use high sensitivity and accurate pressure sensors.

Also, to avoid poor inhaler techniques that prevent patients from receiving their full therapeutic benefits when using inhalers, some medical equipment manufacturers use pressure sensors in inhalers so individuals can receive proper asthma treatment.

All Sensors offers different types of pressure sensors for many medical applications.
