Brief summary
Emerging evidence indicates that elective cardiac surgery patients may benefit from inspiratory muscle training (targeted strengthening of the respiratory muscles) to reduce the incidence of post-operative pulmonary complications (PPCs). However, little is known about the baseline (pre-operative) inspiratory muscle strength of patients undergoing elective cardiac surgery. It is unlikely that every patient requires inspiratory muscle training,and it would be helpful to clarify the proportion of patients who are likely to benefit from such training. This can be easily done through measuring their inspiratory muscle strength pre-operatively as part of their preparation for surgery. However, such measurement is not yet standard practice. We hypothesise that the prevalence of inspiratory muscle weakness may be 30% or greater in a cohort of patients preparing for elective cardiac surgery.

Inclusion criteria
Patients presenting at the pre-admission clinic for assessment prior to elective cardiac surgery (e.g. coronary artery bypass grafting, valve replacements, or any other major open cardiac surgery via sternotomy). Must be able to follow instructions and provide informed written consent.
Exclusion criteria
Patients will be excluded if they cannot provide informed written consent (eg due to physical or intellectual disability). Patients with recent lung surgery, a known pneumothorax, or an inability to maintain a lip seal on the assessment device will also be excluded.
