Mark met representatives on Asthma + Lung UK in Parliament to hear about their new 'Mission for Lung Health'.
They call for action to cut air pollution, faster diagnosis of respiratory conditions, and more money for lung health research.
Respiratory diseases are England's third biggest killer, behind cancers and heart disease.
The Government's target is for 100% of respiratory patients to be seen by the NHS within 18 weeks. In The Wrekin, only 61% of patients are being seen in that time, with 39% waiting longer.
Following his meeting with Asthma + Lung UK, Mark has submitted a parliamentary question to the Health Ministers to ask how they plan to improve services for respiratory patients across Shropshire, Telford & Wrekin.
