Clinical expertise

Physicians provide an array of services at the Adult Cystic Fibrosis Center, Beth Thalheim Asthma Center (ALA Network), Rehabilitation Center, Advanced Lung Disease and Pulmonary Hypertension Center, Sleep Disorders Center, and the outpatient pulmonary practice. Our faculty are leaders in applications for critical care ultrasonography and in demonstrating that people other than radiologists and cardiologists can be proficient. The division has spearheaded the development of national ultrasonography courses and organized training for most of New York City’s first-year pulmonary and critical care fellows – helping raise the level of proficiency in ICUs across the city. At North Shore-LIJ, critical care ultrasonography includes transesophageal echocardiography and training for house staff as well as fellows.

  • Sleep fragmentation — arousals or awakenings during sleep
  • Sleep deprivation
  • Circadian rhythm sleep disorders — sleep disruptions in a person's natural sleep-wake cycle
  • Cardiovascular effects of obstructive sleep apnea (OSA). OSA is a common disorder in which people have one or more pauses in breathing or shallow breaths while they sleep.
  • Effects of the CPAP machine on quality of life. CPAP stands for "Continuous Positive Airway Pressure." The machine helps a person who has obstructive sleep apnea breathe more easily during the night.

The researchers at the world-renowned Feinstein Institute for Medical Research are continually making advances in medicine.
