Spiration Valve System

Freeman is the first and only health system in the area to offer the Spiration Valve System (SVS), which can help alleviate your emphysema symptoms. This safe and effective minimally invasive treatment option is proven to improve lung function, reduce shortness of breath and restore quality of life in those suffering from severe emphysema.

How it works

Air breathed in is redirected away from the diseased part of the lung to the healthier parts. Air and fluids trapped in the diseased part of the lung can then escape. Surgery is not required to place the valve in the airways because the doctor uses a bronchoscope to place the spiration valve. Valves are placed inside the airways using a catheter. The valve then expands and contracts with breathing. More information on SVS can be found at svs.olympusamerica.com.



Freeman now offers MONARCH®!

Using the bronchoscope and sheath telescoping design, MONARCH provides stability and control as a skilled pulmonologist navigates tortuous airways. Each component of the bronchoscope can be independently articulated, advanced, retracted and positionally locked, enabling physicians greater control and maneuverability deep in the lung, where most small nodules are found. This means doctors can detect and biopsy nodules and confirm lung cancer earlier, which results in more effective treatment.

MONARCH® reinvents the concept of the bronchoscope using robotics and a novel telescoping design, enabling it to reach deeper into the lung than conventional methods.

Freeman is the first and only hospital in Missouri, Southeast Kansas and Northeast Oklahoma to use the MONARCH® platform by Auris. The MONARCH® platform integrates the latest advancements in robotics, software, data science and endoscopy. It helps our pulmonologists find lung nodules earlier through the least invasive approach.

Pulmonary Function Testing (PFT)

What is PFT?

PFT is a non-invasive, painless test demonstrating how well the lungs are working.

PFT measures lung volume, capacity, rates of flow and gas exchange.

Testing is completed by a plethysmograph where patients sit or stand in an air-tight box, which looks similar to a small telephone booth.

Not only does PFT save patient time, peace of mind and money, but PFT also provides immediate results and instant treatment, if needed.

Who benefits from PFT? 

While testing can be completed during a routine physical, most of the time it is for patients with a lung condition. PFT assists healthcare providers to determine diagnoses, such as:

  • Allergies
  • Respiratory infections
  • Chronic lung conditions, such as asthma, bronchiectasis, emphysema or chronic bronchitis
  • Asbestosis
  • Sarcoidosis
  • Restrictive Airway problems from scoliosis, tumors, inflammations or scarring of the chest wall
