Calibration & Service

Our most popular option for clinical research, training, and routine ventilator quality assurance

1. Cylinder Leak Test (valid result is less than 40 mL/min leakage)
2. Barometric pressure test (valid result +/- 0.5 kPa)
3. Cylinder Pressure (cmH₂O) high pressure (valid result +/- 0.5 cmH₂O
4. Cylinder Pressure (cmH₂O) low pressure (valid result +/- 0.2 cmH₂O
5. Temperature sensor (˚C) (valid result +/- 0.5 ˚C)
6. Volume calibration (mL) (valid result +/-  20 mL)
7. Full quality inspection with greasing and lubrication of moving parts

For customers who are performing device testing according to very strict protocols

1. Pressure sensor verification – temperature drift uncertainty – measure analog output of pressure sensor in 15 minute intervals (for 1 hour)  (valid result – pressure change of less than 0.15 cmH₂O or +/- 5mV)
2. Pressure sensor verification – zero calibration for pressure and volume (valid result – volume deviations of less than +/- 10 mL and pressure deviations of less than +/-0.1 cmH₂O)
3. 1L syringe volume verification – adult (valid result – less than 20 mL error at nominal volume)
4. 10 mL syringe volume verification – neonatal (valid result – less than 1 mL error at nominal volume)
5. Compliance verification for C50, C10, C1 (valid result – compliance within 5% or +/- 0.2mL/cmH₂O, whichever is greater)
6. Dynamic volume verification – spontaneous breathing error (valid result – peak volume levels within +/- 30mL of target volume of 1.7L)
7. Dynamic volume verification – pump mode validation error (valid result – deviation of +/- 10mL from target volume of 500mL)
8. Peak Flow validation – piston vs. model (valid result – model and piston are within +/- 2% at peak flows of 200L/min)
9. Resistance verification for parabolic and linear resistance at 5, 20, 100, 500 cmH₂O/L/s (valid result – +/- 10% of expected pressure drops at flows per ASTM F-1100)
