Brief summary
Exercise is undertaken as part of usual physiotherapy care following heart surgery. While it is considered safe, the exact effects of exercise which is commony prescribed following heart surgery by physiotherapists on heart function, breathing rates and oxygen levels are unknown. Establishing this information will further inform exercise prescription guidelines for physiotherapists who care for people following heart surgery. The aim of this study is to determine the relationship between heart rate, respiratory rate and oxygen saturation and measures of physical function and exercise intensity following heart surgery. People who have undergone heart surgery and require physiotherapy following surgery will be recruited for this study. During the usual physiotherapy tasks which involves exercise, and tests of balance and leg strength, measurements of heart function, breathing rate and oxygen levels will be extracted from the continuous monitoring system of which all people following cardiac surgery are connected to. Participants will be asked to rate their level of breathlessness and exertion following exercise. The relationship between exercise intensity and measures of heart function, breathing rate and oxygen saturations will be assessed.
Interventions
The participants will undertake a test of their physical function and exercise (mobilisation). Although the exercise is considered usual physiotherapy care after cardiac surgery, completing the test of physical function is not part of usual care.
The test of physical function will be the short physical performance battery and will include a measure of walking speed, lower limb strength assessment during a sit-to-stand activity and a measure of balance.

The participants will undertake a test of their physical function and exercise (mobilisation). Although the exercise is considered usual physiotherapy care after cardiac surgery, completing the test of physical function is not part of usual care. The test of physical function will be the short physical performance battery and will include a measure of walking speed, lower limb strength assessment during a sit-to-stand activity and a measure of balance. The exercise undertaken will be walking performed on the ward, the distance and intensity determined by the physiotherapist. The exercise prescription and completion of the short physical performance battery will be administered by the participant's treating physiotherapist. The exercise and test of physical activity will take approximately 20 minutes maximum to complete and will be undertaken at Day 3 post cardiac surgery, on the ward. During the exercise and test of physical function, cardiorespiratory parameters (heart rate, respiratory rate and oxygen saturation) will be measured and the levels of perceived exertion and dyspnoea will be recorded.
