First, look at the patient, not only the number. If the patient is struggling to breathe or looks seriously unwell, seek urgent medical help. If the patient is stable, repeat the reading correctly, check the cannula or mask and tubing, confirm the oxygen device is running, and contact the treating team. Do not increase the prescribed flow independently.
“The concentrator is on, but the oximeter still shows a low number—should I turn the flow up?” This is a high-stress moment. A pulse oximeter is an estimate, and the reading can be affected by movement, cold hands, nail products, circulation and device limitations. But a low reading with symptoms can also indicate genuine deterioration.
Let the patient rest if possible. Warm a cold hand, remove obvious nail obstruction where practical, keep the hand still and wait for the pulse indicator and number to stabilise. Try another finger if the signal is poor.
Compare the oximeter pulse rate with the patient’s actual pulse if you know how. A wildly mismatched pulse can suggest a weak signal. Never use one number in isolation when the patient’s condition looks worse.
Confirm the concentrator is powered, running and not showing an alarm. Make sure tubing is connected, not kinked, trapped under furniture or filled with water. Check that the nasal cannula is positioned in the nostrils or the prescribed mask sits correctly.
If using a cylinder, check that the main valve is open, the regulator is correctly fitted and the contents gauge is not empty. Do not attempt repairs to high-pressure connections.
If the patient has severe breathlessness, cannot speak normally, becomes confused or unusually sleepy, develops blue or grey lips, chest pain or rapidly worsening symptoms, seek emergency help. Do not wait for several more readings.
For a stable patient with repeated readings outside the target range given by the clinician, contact the treating team promptly. Some conditions have individual oxygen targets, which is why generic internet thresholds should not replace the prescribed plan.
Use the flow rate, duration and delivery device prescribed by the treating clinician. If the patient is breathless, unusually drowsy or confused, has blue or grey lips, chest pain, or is deteriorating, seek urgent medical help. Equipment checks must not delay emergency care.
Yes. It estimates oxygen saturation and can be affected by several factors. Repeat carefully and consider symptoms.
No. Changing flow without clinical advice can be unsafe, especially in some chronic respiratory conditions.
Tubing length, kinks, leaks and connections can affect delivery. Use the setup approved for the device and prescription.
The cause may be measurement error, the patient’s condition or another part of the setup. Contact the clinical team and escalate urgently if symptoms are severe.
Keep the prescription ready, including flow rate and duration, then compare Sanjeevia’s oxygen-support options. Confirm the exact equipment, backup plan, accessories, demonstration and current availability before booking.
