Respiratory Physiology

Operating from both City Hospital and Sandwell Hospital sites, we are a large respiratory physiology and sleep physiology service providing your doctor with a diagnosis of your condition. This will include lung function tests and home oxygen assessment and reviews (HOSAR).

We also carry out sleep studies to assess whether you will need Continuous Positive Airway Pressure (CPAP) or Domiciliary Non-Invasive Ventilation (NIV) therapy.
