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.

Pressure Sensing in Healthcare

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

Pressure Sensing in Healthcare

When we’re young, it seems that the thermometer is the essential measurement to determine well versus sick. As we age, pressure becomes increasingly important. Initially, it determines a proper blood pressure level—with less than 120 over 80 (mm Hg) being the desired range.

Proper eye care involves glaucoma testing that uses pressure to determine the onset of this disease. Normal intraocular pressures average between 12-22 mm Hg.

A common tool for detecting the onset of respiratory problems is the spirometer or pneumotachograph. In this case, the reading is airflow rate calculated from a change in pressure drop (∆P) during inhaling and exhaling and can also be used for indirect measurement of lung volumes and capacities. The actual differential pressure measurement is quite low, typically requiring a sensor with as low as ±500 P (±3.75 mm Hg) range to obtain acceptable resolution.

These are the more common pressure measurements that separate a heathy from a sick person. Those with health problems may learn the difference between in vivo and ex vivo pressure measurements, and the use of pressure measurements in respirators, ventilators and more.
