Pulmonary Medicine

At Norwalk Hospital, we’re committed to providing the educational opportunities that enable our fellows to pursue careers in clinical care, administrative leadership and academic medicine.

The education of fellows occurs in diverse sites that capitalize on the strengths of our affiliates. The pulmonary training is based primarily at Norwalk Hospital. Fellows also rotate through the pulmonary consultation service at Yale-New Haven Hospital, which is the primary teaching site at Yale. Fellows pursuing additional critical care training at Yale University rotate through Surgical, Neurosurgical and Medical Intensive Care Units and the Thoracic Interventional Program at Yale-New Haven Hospital as well as through the West Haven Veterans Administration Medical Center Pulmonary/ICU Service. Fellows also perform a rotation at the University of Connecticut-affiliated Hospital for Special Care, an outstanding pulmonary rehabilitation hospital.

Norwalk Hospital graduates are highly prepared to meet the clinical and academic expectations of our profession.

During the two-year Pulmonary Fellowship, fellows complete 16 months of clinical training. Again, training occurs primarily at Norwalk Hospital. Fellows also rotate in their second year on the Yale-New Haven Hospital Consult Service and attend weekly continuity clinics in both a private office and clinical settings, except when on critical care rotations. Technical training in cardiac echo is performed at Norwalk Hospital.  Norwalk Hospital also hosts an accredited Fellowship in Sleep Medicine, in which many Pulmonary fellows have trained following completion of their Pulmonary training at Norwalk and Critical Care training at Yale.

Program Information

Intensive Care Unit

The Intensive Care Unit (ICU) is a 16-bed state-of-the-art medical-surgical unit. Along with a teaching attending, fellows conduct daily radiology and work rounds with a multidisciplinary team that includes residents, medical students, a pharmacist, dietitian, nurses and respiratory therapists. Daily rounds with physical rehabilitation staff and nurse managers promote early mobilization and awake mechanical ventilation. In addition to overseeing the care of all medical patients, fellows work closely with the surgical team on selected cases.

Pulmonary Consultation Service

The Consultation Service provides pulmonary consultations to all units of the hospital including Medicine, Surgery, Post-operative Care, Rehabilitation, Obstetrics and Emergency Medicine.  Fellows are supervised by the nine attending pulmonologists. Case review and didactic sessions are conducted by a dedicated teaching attending, who also interprets pulmonary function tests with the fellow. Medical students and residents on elective join the fellow on the service and teaching rounds.

Yale-New Haven Consultation Service

Second-year fellows rotate on the Pulmonary Consultation Service at Yale-New Haven Hospital. This rotation provides exposure to transplantation-related pulmonary disorders and also introduces the fellow to the systems of care at Yale-New Haven Hospital. During this rotation, the fellows may have the opportunity to interact with the specialty clinics in interstitial lung disease, pulmonary hypertension and adult cystic fibrosis.

Critical Care Ultrasound and Cardiac Echo

This rotation is divided into two two-week blocks, one at the beginning of the first year and the other toward the end. The fellows spend half of each day at Norwalk Hospital learning the basics of performance of echocardiography in the Cardiology Section. The remainder of the time is devoted to self-study utilizing videos and texts and practical applications with echo simulation using SonoSim®.  The fellow reviews echocardiograms performed at Norwalk Hospital with the attending cardiologist.  The second rotation provides the fellows the opportunity to refine their echo technique after employing it clinically during the intervening rotations. Dr. Ian Weir oversees the fellows’ performance during this rotation.

Sleep Medicine

In their second year, fellows spend two months in Sleep Medicine at Norwalk Hospital’s accredited Sleep Disorders Center. This busy service housed in new facilities just offsite performs more than 1,000 sleep consultations, 1,500 polysomnograms, and 100 MSLT and MWTs per year. The fellows work with three board-certified attendings, including a pediatric sleep specialist and insomnia expert on all sleep disorders. Fellows attend the lectures of the Sleep Fellowship. This experience provides the Pulmonary fellows with the opportunity to decide whether to pursue further training in Sleep Medicine.

Pulmonary Function Laboratory

Fellows in their first year spend a two-week block learning how to conduct and interpret pulmonary function tests, challenge testing, and cardio-pulmonary exercise testing under the direction of Brian Mitchell, RPFT, Director of the PFT Laboratory.

Pulmonary Rehabilitation

Pulmonary Rehabilitation at Norwalk Hospital is a nationally recognized service directed by Dr. Amy Ahasic. Fellows spend two weeks working in this ambulatory service to learn how to provide this essential and uplifting part of comprehensive pulmonary care. Fellows also have the opportunity to pursue research related to pulmonary rehabilitation.  

Long Term Acute Care (LTAC) rotation

Conferences & Research

Norwalk Hospital’s commitment to education is evidenced by its highly active conference schedule that combines workshops, faculty and invited speakers, and fellow-led activities. Weekly conferences include:
Connecticut State Chest Conference hosted at Yale New Haven Pulmonary, Critical Care, and Sleep Department. This one-hour weekly conference features exceptional case presentations and lectures from internationally renowned pulmonary-critical care physicians. During the summer months, State Chest is devoted to lectures on common pulmonary and critical care disorders.

Norwalk Pulmonary Section Conference. This weekly series entails a rotating format of invited expert speakers, topical lectures from Section members and fellows as well as Morbidity and Mortality, Pathology, and Quality and Safety lectures.

Ambulatory Case Conference. Dr. Amy Ahasic, Section Chief, conducts this broad-ranging weekly session, in which ambulatory cases and topics are examined in depth.

Pulmonary Physiology Lecture Series. Each year, the fellows and faculty participate in a 12-lecture course that provides grounding in respiratory physiology.

Research Conference. This conference focuses on the research of the Pulmonary and Sleep fellows. Fellows also participate in Norwalk Hospital’s bi-weekly multidisciplinary Thoracic Tumor Board. Additional conferences include journal club, POCUS conference, Interstitial Lung Disease case conference, weekly Sleep Medicine conferences and Internal Medicine Grand Rounds.

By integrating our comprehensive clinical training experience with the opportunity to engage in clinically-oriented research, our fellowship program prepares fellows to combine excellent patient care with investigational endeavors. All fellows participate in clinically related research endeavors in a variety of areas including critical care medicine, pulmonary medicine, outcomes research, sleep medicine and quality improvement. The research training at Norwalk has successfully prepared fellows for university-based positions as well as hospital leadership posts. Fellows have access to statisticians and receive close mentoring by faculty.

Examples of previous projects pertain to the study of 30 day readmission of COPD, management of environmental hypothermia, evaluation of pulmonary embolism, and implementation of ARDS protocol. The Section also participates in NIH-sponsored trials such as the PROCESS study, which evaluated the outcome of sepsis treatment with Early Goal Directed Therapy versus routine care and the Procalcitonin Antibiotic Consensus Trial. High-level statistical support and professional coordinators are available to assist the fellows in their research.
