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.
The Pressure in Hyperbaric Chamber Healing
In Hyperbaric Oxygen Therapy (HBOT), a patient breathes 100% oxygen intermittently while inside a treatment chamber maintained at a pressure higher than sea level pressure (>1 atmosphere absolute). The patient inhales the oxygen within the chamber, where the pressurization could be 1.4 atmosphere absolute or higher.
HBOT can be a primary treatment or used to supplement surgical or pharmacologic approaches to healing. Specific medical uses include:
- Air or gas embolism
- Carbon monoxide poisoning
- Gas gangrene
- Crush Injuries, compartment syndrome (excessive pressure inside an enclosed muscle space in the body) and other acute traumatic ischemias (inadequate supply of blood to organs and body tissues)
- Decompression sickness
- Inadequate blood flow in arteries
- Severe anemia
- Intracranial abscess
- Dermatological disorders, such as Necrotizing Soft Tissue Infections
- Compromised grafts and flaps
- Acute thermal burn injury
- Sudden deafness
Effective HBOT treatment involves controlling three parameters: %O2, pressure, and time. While, mechanical analog gauges are the standard method for measuring pressure in commercially available hyperbaric chambers and are typically accurate only to within ±2% of full scale, digital pressure gauges with considerably greater accuracy and remote monitoring and control capability are being considered. A recent patent for a hyperbaric chamber suction system, including hyperbaric oxygen chamber, proposes the use of two electrically connected digital pressure gauges with an externally connected digital display as well as electrical solenoid valves and a programmable logic controller (PLC) to maintain desired pressure levels.
