Personal Biography

Dr Susannah Bloch is a respiratory physician and her NHS practice is at St Mary’s Hospital in Paddington, Imperial College’s busy acute hospital. She is the lead for Lung Cancer for Imperial College Healthcare NHS Trust and runs the Imperial Lung Cancer MDT working closely with the wider thoracic and oncology teams. She is also responsible for managing the lung cancer pathway for patients from pre-diagnosis, supporting patients through their diagnosis and then on to referral for treatment.

Dr Bloch also runs the acute Non-Invasive Ventilation service and the Acute Respiratory Unit. She does acute general medical on calls and looks after general medical and respiratory inpatients. She also leads the tracheostomy ward round and manages inpatient tracheostomy weaning off ICU. Her experience includes management of obesity hypoventilation and obstructive sleep apnoea with NIV and CPAP. Besides this, she also does a general respiratory clinic diagnosing and treating all general respiratory diseases and has a weekly bronchoscopy list.

Dr Bloch trained at St Mary’s Hospital, Imperial College School of Medicine in London and since qualifying has also gained both an MSc in respiratory medicine and a research PhD in the field of post critical illness muscle wasting.

“….. A massive thank you for looking after me.. you have gone above and beyond, have been so caring and understanding. I really appreciate it and just wanted to let you know how incredibly special you are.”  – Patient LI 2018
