Chapter 6 - M & C AINTENANCE ALIBRATION Operating Theory ® The LTV 1200, 1150, and 1100 ventilator utilizes an electromechanical pneumatic system under the control of a microprocessor to deliver patient ventilation. The following diagram and descriptions illustrate the major components of the ventilator and their respective functions.
Page 41 Ventilation gas exiting the Flow Valve is connected to the Wye and Exhalation Valve by a patient circuit. The Flow Sensor at the Wye measures the exhaled flow using a fixed orifice type transducer. Transducer sensor ports are located between the patient and ventilator connection ports. The Exhalation Valve provides the following functions: 1) Closes the exhalation port during inspiration to divert gas to the patient.

Page 65: Flow Valve Calibration (Vhome Trim)
Flow Valve Calibration (VHome Trim) The flow valve should not normally require recalibration from its factory set values. However, some circumstances, such as mechanical shock, may cause the flow valve calibration to change from its factory-set condition. This flow valve calibration procedure can be used to adjust the flow valve calibration setting to compensate for improper flows measured during the Performance Checkout procedure.
Page 66 Read the flow value from the flow meter. Correct flow shall be 9.4 to 9.8 Lpm (ATP) or 9.7 to 10.0 Lpm (BTPD).  If the flow is between 9.4 to 9.8 Lpm (ATP) or 9.7 to 10.0 Lpm (BTPD), no flow vlave calibration is needed ...

Advanced FiO Diagnostic Procedures (LTV 1200 Only) ® Delivery of the correct percentage of oxygen (FiO ) is dependent on correct calibration of the oxygen pressure transducer, flow valve and O blender. If the FiO appears incorrect, perform the following diagnostic procedures. When instructed to replace a subassembly or component that fails any of the following checks, verify the original problem is resolved once the item has been replaced.
Page 105 If the flow output is out of the acceptable output flow range, perform the following, in the order shown.  Check all flow valve flexible tubing for leaks or occlusions and replace any damaged components.  Recalibrate the flow valve transducer (see Valve Differential Calibration in Chapter 6 for instructions).

Page 339: Tools, Required
Tools, Required ® Service, Calibration and Testing require instrumentation tools or test equipment with documented calibrated traceability to NIST standards. The instrumentation and test equipment must also have sufficient accuracies to attain industry standard performance levels. Instrumentation accuracy is typically specified “percent of full scale” or “percent of reading”. The required minimum accuracy levels are typically the specification tolerance divided by four (4).
Page 340 Flow rate measurements 10 Lpm When measuring a flow rate of 10 Lpm with a tolerance of ± 1.5 Lpm, the minimum accuracy level for instrumentation would be 1.5 Lpm / 4 = 0.375 Lpm. If the instrument accuracy is 2% of reading, at 10 Lpm the resulting accuracy is 10 Lpm x 2% = 0.2 Lpm.
Page 341 When measuring oxygen blending of 60% with a tolerance of ± 5%, the resulting minimum accuracy level for instrumentation would be 5% / 4 = 1.25%. If the instrument accuracy is 2% of reading, at 60% the resulting accuracy is 60% x 2% = 1.2%.
