Pulmonary Conditions

Pulmonary conditions prevent you from breathing well. Our pulmonologist at O2 Pulmonary and Sleep Group can provide an accurate diagnosis and prompt treatment to improve your respiratory condition.

Some of the pulmonary conditions our pulmonologist treats include:

  • COPD
  • Asthma
  • Bronchiectasis
  • Pulmonary Hypertension
  • Pneumonia
  • Interstitial Lung Disease
  • Cough
  • Bronchitis
  • Sarcoidosis
  • Tuberculosis
  • Lung Cancer
  • Smoking Cessation
  • Lung Nodules


At O2 Pulmonary & Sleep Group, we perform a variety of pulmonary services, including:

  • Bronchoscopy – a visual examination of the air passages leading into your lungs
  • Thoracentesis – the removal of fluid from the pleural space between the chest wall and lungs for laboratory testing
  • Pulmonary function tests – non-invasive tests that measure how well your lungs take in, absorb and release air
  • Bronchial thermoplasty – a new FDA-approved treatment option for asthma


Sleep Disorders

The sleep specialists at O2 Pulmonary & Sleep Group can help you discover the source of your sleep disorder. We perform polysomnogram, a test that electronically recorders certain physiological functions and physical activities as you sleep.

Our sleep specialists can diagnose any sleep disorders you may have so that you can get the rest you need. Some sleep disorders, such as insomnia and restless leg syndrome, can cause poor sleep, lead to daytime sleepiness and diminish the quality of your life. Narcolepsy and sleepwalking disturb sleep but also cause significant life disruptions.

Sleep disorders that cause you to stop breathing while you sleep, such as obstructive sleep apnea and central sleep apnea, can cause your oxygen levels to drop. Frequent drops in blood oxygen coupled with poor sleep can release stress hormones, which raise your heart rate and increase your risk for high blood pressure, stroke, heart attack and more. The sleep specialists at O2 Pulmonary & Sleep Group can also help you choose a continuous positive airway pressure, or CPAP, machine to help you overcome sleep apnea.
