To use an oxygen flow meter, follow these steps:
1. Connect the oxygen source: Ensure that the oxygen source (such as a cylinder or concentrator) is securely connected to the flow meter's inlet.
2. Set the flow rate: Adjust the flow control knob to the prescribed flow rate. Some flow meters have a rotating knob or a sliding mechanism to select the desired flow rate. Align the indicator on the flow rate scale to the prescribed value.
3. Monitor the flow rate: As the oxygen flows through the flow meter, check the flow rate indicator. It will display the actual flow rate in liters per minute. Ensure that the indicated flow rate matches the prescribed rate.
4. Attach the oxygen delivery device: Connect the oxygen delivery device, such as a nasal cannula or mask, to the flow meter's outlet.
5. Monitor and adjust as needed: Throughout the oxygen therapy session, continue to monitor the flow rate to ensure it remains consistent with the prescribed rate. If necessary, make adjustments to the flow control knob.
