Oxygen Gauge Normal
A normal oxygen tank pressure for a full welding cylinder is around 2,200 psi (pounds per square inch), while normal working delivery pressure ranges from 5 to 15 psi depending on your torch tip size and task
Description
Oxygen Gauge Normal
A normal reading on a pulse oximeter (oxygen gauge) is 95% to 100% oxygen saturation (SpO₂).
Normal Features & Readings
- Oxygen Saturation (SpO₂): 95% – 100% for healthy individuals at rest.
- Pulse/Heart Rate: 60 – 100 beats per minute (bpm) for a normal resting adult.
- Display Elements: A standard digital screen shows two primary metrics: percentage of blood oxygen (SpO₂%) and pulse rate (PR bpm), often accompanied by a plethysmograph (pulse wave/amplitude bar).
- Factors Affecting Accuracy
- Low Readings: Levels consistently below 92% may indicate hypoxemia (low blood oxygen) and require medical evaluation.
- Interferences: Cold hands, dark nail polish, artificial nails, or movement can cause false or low readings
Specification
| Specification Parameter | Typical Medical Standard / Value | Description |
|---|---|---|
| Inlet Pressure Range | 0 to 3,000 PSI (0 to 200 bar) | Measures the high pressure inside the oxygen tank. |
| Outlet/Delivery Pressure | 50 PSI (approx. 3.5 bar) | The constant working pressure delivered to the flowmeter. |
| Flow Rate Selection | 0 to 15 Liters Per Minute (LPM) | Pediatric models may offer lower ranges like 0–4 LPM. |
| Inlet Connection Type | CGA 540 (Bulk tanks) or CGA 870 (Pin-index for portable D/E cylinders) | Standardized fittings to prevent cross-connection with other gases. |
| Outlet Connection | DISS 1240 (Diameter-Index Safety System) or Hose Barb | Connects directly to oxygen tubing or humidifiers. |
| Gauge Dial Diameter | 1.5 inches to 2 inches (38 to 50 mm) | Sized for clear readability of pressure levels. |
| Material Construction | Anodized Aluminum Body with Brass Core/High-Pressure Components | Ensures durability and strict safety in high-pressure oxygen environments. |
| Safety Features | Built-in Relief Valve & Internal Sintered Bronze Filter | Protects against over-pressurization and blocks microscopic contaminants. |
| Compliance Standards | FDA Registered, CE Certified, ASTM G175 | Meets international cleanliness and safety standards for oxygen service. |
