How to fix no oxygen flow through oxygen flowmeter in Smiths Medical Equipment?

  Laurie WalkerAug 2, 2025
  If there is no oxygen flow through the oxygen flowmeter, several factors could be at play. First, ensure the oxygen tank isn't empty; if it is, use a full one. Also, verify that the oxygen tank is turned on. If the regulator is defective, press the Flush Valve to check if the machine is receiving oxygen. Check the oxygen hose to ensure it is properly connected and tightened at both the machine and the oxygen source. Finally, a damaged Needle Valve could be the culprit, requiring replacement.

What to do if patient does not respond to anesthetic agent with Smiths Medical Equipment?

  If a patient isn't responding to the anesthetic agent, several factors should be investigated. Initially, check for leaks in the anesthesia machine by performing a Pressure Test using the Daily Machine checklist. Ensure that the oxygen flow is adequate, increasing it to at least 1 LPM. Verify that the vaporizer has an adequate amount of agent, filling it to the top fill line. Also, check for excessive draw or vacuum from the Active Waste Gas Scavenger, and reduce it if necessary. Lastly, check the service due date on the side of the vaporizer.

Why rebreathing bag over inflates (Pressure is over 5 cm H O) 2 in Smiths Medical Equipment?

  caitlyn09Aug 14, 2025
  If the rebreathing bag over inflates, with pressure exceeding 5 cm H2O, several potential causes exist. First, the bag size might be inappropriate for the patient; check the bag size and replace it if necessary. The pop-off valve might be partially or completely closed or malfunctioning; ensure it is fully open. An obstruction in the Charcoal Canister could also be the issue; position it to allow proper gas flow. Lastly, a defective Flush Valve could be the cause, requiring inspection and replacement if needed.

  If the machine fails the Pressure Test on the Daily Machine Checklist, it indicates a leak within the anesthesia machine. Begin by inspecting the absorber canister. Check for loose granules underneath the absorber gasket and ensure the vaporizer end caps are securely in place. Examine silicone hose connections for punctures, and inspect the bag and circuit hoses for any damage. Finally, verify that the vaporizer fill cap is tight.

  If the rebreathing bag does not inflate, it may be due to a leak in the anesthesia machine; perform a Pressure Test using the Daily Machine checklist to identify any leaks.
