Conditions
Interventions
This study has been designed to compare camera monitoring against two established methods of measuring cardiac output (amount of blood pumped out by the heart per minute). As this is a pilot/proof of
a physical exercise using an exercise bike and cold pressor test where a hand is placed in cold water. The monitors are recording the participant s physiological variables including: heart rate, strok

Inclusion criteria
Inclusion criteria: 1. Healthy volunteers 2. Age 18-60 3. Participant is willing and able to give informed consent for participation in the study.
Exclusion criteria
Exclusion criteria: 1. Patient whose anatomy, condition, or other required monitoring precludes the use of the camera equipment, transthoracic echocardiogram, or thoracic bioimpedance monitor kit. Examples include thoracic wall deformity not allowing transthoracic echocardiography. Equally, difficulty obtaining an adequate transthoracic echocardiography window due to breast tissue will be taken as a relative contraindication for enrolment 2. History of cardiovascular disease 3. Any current or previous leg injuries which precludes the use of a bicycle-like device
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Changes between face to hand pulse transit time/skin colour change/skin temperature change is measured using a camera at baseline and throughout the recording period of 60 minutes, and compared to gold standard monitoring using a bioimpedance monitor. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Changes between Face to hand pulse transit time/Skin Colour change/Skin temperature change is measured using a camera at baseline and throughout the recording period of 60 minutes, and compared to gold standard monitoring using transthoracic echocardiogram 2. Stroke volume estimates throughout the recording period of 60 minutes are compared using the three methods: camera, bioimpedance monitor, transthoracic echocardiogram | — |
