| Preparation |
| Clinical Standards for Procedures and Interventions. |
|
|
| Verifies the ordered oxygen concentration and target saturation and identifies the exact location where delivered oxygen must be measured. |
|
|
| Inspects the analyzer, sensor, cable, sampling adapter, battery, calibration status, sensor expiration, and service condition. |
|
|
| Calibrates or verifies the analyzer with known gas concentration(s) exactly as specified by the analyzer manufacturer and local quality-control policy. |
|
|
| Implementation |
| Places the sensor or sampling adapter at the actual patient-delivery point while preventing ambient-air dilution, leaks, excessive pressure, and contamination. |
|
|
| Allows the reading to stabilize and records the measured FIO2, then compares it with the prescribed concentration and the device setting. |
|
|
| Verifies high and low oxygen alarms when continuous analysis is used and confirms alarm limits are clinically appropriate. |
|
|
| Monitoring & Modifications |
| Repeats oxygen analysis after changes in flow, blender setting, circuit, interface, humidification, gas source, or patient-delivery configuration. |
|
|
| For an unexpected value, assesses the patient first and then checks calibration, sampling location, leaks, condensate, source gas, flow, and device function before changing therapy. |
|
|
| Titrates oxygen only within an authorized order or protocol while monitoring oxygen saturation and clinical response. |
|
|
| Post-Intervention |
| Documents analyzer identification or quality-control status when required, sampling location, device setting, measured FIO2, patient response, and corrective actions. |
