The l (RHH) recently opened its new Department of Diving and Hyperbaric Medicine, featuring a state-of-the-art dual-capability hyperbaric chamber. Designed by and powered by a compressed air system, the chamber is reported to be a first for the Southern Hemisphere 鈥� delivering patient treatment and a world-class research and training facility.

Treating patients with a medical hyperbaric chamber

A medical hyperbaric chamber is used to deliver hyperbaric oxygen treatment (HBOT) 鈥� a well-known therapy for treating decompression illness; as such it is essential for commercial and recreational diving industries. HBOT is also used to treat patients with medical conditions such as diabetic ulcers, tissue injury from radiation after treatment for cancer, osteoradionecrosis and serious infections such as gangrene.

HBOT works by increasing the partial pressure of oxygen in the blood and tissues. The patient sits or lies in a hyperbaric chamber, where the pressure is increased to 2.4 atmospheres, and is given 100% oxygen to breathe via a mask or hood system. The high partial pressure of oxygen increases the diffusion distance that oxygen can penetrate into tissues. Repeated hyperoxic stimulation has proven to accelerate the healing process 鈥� on average a patient undertakes around 20 to 40 treatments over the course of four to eight consecutive weeks.

A first for the Southern Hemisphere

Queensland-based Fink Engineering designed and engineered the rectangular shape for hyperbaric chambers in 1994 and was reportedly the first company internationally to design such a chamber, which has been used effectively ever since.

Unlike traditional cylindrical-shaped and double-locked hyperbaric chambers with a typical patient capacity of two to five patients, the rectangular-shaped hyperbaric chambers feature a triple lock and can simultaneously treat up to 10 patients.

The hyperbaric chamber now in operation at the RHH is fitted with a depressurisation capability to simulate altitude. There are currently only a few dual-capable chambers like it in the world. Said to be a first for the Southern Hemisphere, this can pressurise (hyperbaric) and depressurise (hypobaric), meaning that aside from treating patients with its hyperbaric capabilities, the chamber can be used for altitude research and training using its hypobaric capabilities. It will be possible for researchers, for example in the aerospace sector, to study the effects of high altitude on the body, in particular low oxygen levels and low ambient air pressure.

Clinical Professor David Smart, Royal Hobart 黑料吃瓜群网 hyperbaric facility medical co-director, prepares the hyperbaric chamber for patients.

Delivering high quality and high volumes of clean and medical breathing air

High-quality, dry and clean compressed air is essential for a medical hyperbaric chamber to operate. Once patients have been fitted with a breathing mask or hood system, the doors to the hyperbaric chamber are closed. The atmospheric pressure inside the chamber is then increased by opening values that allow high-pressure air to enter.

For many years, Fink Engineering has chosen Kaeser compressed air equipment. In the case of RHH, two CSD 125 T rotary screw compressors with integrated refrigerant dryers along with a comprehensive air treatment package were chosen.

鈥淭he hyperbaric chambers require high quality and high volumes of clean and medical breathing air that meets Australian and New Zealand standards. It is essential that the air is medical grade and clean,鈥� Fink Engineering Project and Maintenance Supervisor George Fink explained.

鈥淪taff inside the chamber breathe pressurised air while attending to patients. Patients receive hyperbaric oxygen treatment while breathing from a mask or a hood. They also breathe the hyperbaric chamber air when taking short breaks during treatment.

鈥淚t is essential that the compressed air system is reliable. Ultimately the last thing you would want is a compressor failure to stop the chamber functioning mid-treatment. That鈥檚 also a reason we chose to install a double redundancy system. That way there is always a backup compressor if required to supply the compressed air needed to finish a treatment,鈥� Fink said.

A reliable and efficient solution

鈥淲e鈥檝e found the Kaeser compressed air equipment to be very reliable and efficient in delivering absolutely clean and dry compressed air to these hyperbaric units,鈥� Fink said.

鈥淚n fact, many of our installations in hospitals throughout Australia operate with a Kaeser compressed air system 鈥� some for as long now as 15 years. They just keep working!鈥�

Clinical Professor David Smart, RHH hyperbaric facility medical co-director, added, 鈥淲e are delighted with our state-of-the-art hyperbaric facility which has been manufactured by Fink.

鈥淔ink recommended the Kaeser compressed air system due to their proven track record. We have been operational now for three months and the system is going well. Our staff are looking forward to welcoming more patients with our greater treatment capacity and opening our facility for research and teaching.鈥�
