•1. Patients who have a single intercostal chest drain in situ and which the treating clinician has determined requires removal.
•2. Willingness to give written informed consent and willingness to participate in and comply with the study.

•1.Patients who have any radiological evidence of a residual pneumothorax prior to chest drain removal.
•2.Patients who have more than 200mls of residual pleural fluid prior to chest drain removal as estimated on plain chest radiograph.
•3.Patients who have had an air leak into the underwater seal within 24 hours prior to chest drain removal.
•4.Patients with resting hypoxaemia (defined as a partial pressure of oxygen - PaO2 - of less than 55mmHg or saturation - SaO2 - of less than 90% on room air prior to the removal of the chest drain).
•5.Patients who have undergone a pleurodesis procedure.
•6.Patients who have more than one chest drain in situ at the time when one drain is to be removed. This applies to bilateral drains in patients who have undergone bilateral lung or heart-lung transplantation as these patients have a continuous communication between right and left hemithoraces; however once there is only one remaining drain for removal these patients would then become eligible for inclusion in the study.
•7.Patients who are unable to clearly understand or comply with the nurse’s instructions with regard to the technique of breath holding during the removal of the chest drain.
