Brief summary

Up to 20% of patients over 50yr presenting for elective surgery may have episodes of obstructed breathing e.g. snoring, which is likely to worsen and become a significant risk after surgery. Use of a recorder to continuously monitor breathing for the 12 hours immediately after surgery may help us to identify the most useful risk factors to look for during the assessment of patients at the clinic prior to surgery.

Interventions

Continuous respiratory monitoring 8 hours with Somte portable monitor. Identification of risk factors at pre-operative assessment.
