Although appropriate sedation is recommended during colonoscopy, patients are at risk for adverse events e.g hypoventilation and hypoxemia due to inadvertent oversedation. The aim of this study was to evaluate the benefit of additional quantitative capnography monitoring ( respiratory rate )in management of patient undergoing colonoscopy under sedation in preventing or reducing the incidence of adverse events and also determine when to start the procedure and when to give and not to give increments of sedative drugs during the procedure.

| Standard capnography | Procedure | Patients undergoing colonoscopy under sedation were randomly assigned to receive standard capnography monitoring or modified capnography monitoring which can be achieved by tucking capnography probe under the face mask.74 patients were enrolled. Patient characteristics were well balanced between the two groups 37 patients in each group. |

| Modified capnography | Procedure | If Respiratory rate below 14 b/m: more sedation isn't not advised and the patient may develop airway obstruction and needs airway intervention ( like jaw thrust or oral airway) If respiratory rate more than 20 b/m it means this patient is prone to awake or to move and this patient in need for incremental dose of sedative drug ( e.g 20 to 30 mg propofol) Also roughly speaking respiratory rate from 16 to 18 b/m is the target |
