|
|
| Verifies the oxygen order or protocol, patient-specific oxygen-saturation target, required flow range, and intended patient interface. |
|
|
| Inspects the blender, high-pressure hoses, gas-specific connectors, outlet, flowmeter, alarm or bypass function, and service status; removes damaged or overdue equipment from use. |
|
|
| Connects medical air and oxygen to the correctly labeled gas-specific inlets and confirms both source pressures are within the manufacturer-specified operating range. |
|
|
| Connects a calibrated oxygen analyzer at the actual blender outlet or downstream point of delivery and allows the system to stabilize. |
|
|
| Implementation |
| Sets the prescribed fraction of inspired oxygen (FIO2) and total flow, using a flowmeter designed and oriented for the mixed gas and operating pressure. |
|
|
| Measures delivered FIO2 at the point of delivery and confirms agreement with the blender setting within the device and institutional tolerance before patient connection. |
|
|
| When permitted by the manufacturer and local policy, verifies the source-failure alarm or bypass one source at a time without interrupting patient care, then restores both sources. |
|
|
| Monitoring & Modifications |
| Continuously or intermittently monitors delivered FIO2, flow, alarm status, patient oxygen saturation, respiratory status, and clinical response as appropriate to acuity. |
|
|
| Investigates discrepancies by checking source pressure, hose and connection integrity, flowmeter orientation and calibration, downstream resistance, leaks, analyzer calibration, and blender function. |
|
|
| Reanalyzes delivered oxygen after any change in FIO2, flow, interface, circuit, source pressure, or equipment configuration. |
|
|
| Post-Intervention |
| Documents prescribed and measured FIO2, total flow, source and alarm verification, patient response, and any troubleshooting or equipment removal. |
