Status Messages
The following information messages are included in the var:VarValue or var:Validity fields of messages that are generated by the MedicalDeviceInput node.
General status messages
Value | Meaning |
---|---|
CM_POSITIVE | Boolean true |
CM_NEGATIVE | Boolean false |
CM_NO_VALUE_YET | The device is connected correctly, but a value is not yet available. For example, if the measurement must be taken manually by using the device and this has not yet happened. |
CM_VALID | This means that the measurement shown in the var:VarValue field is valid. |
CM_UNCERTAIN | This value is used in the var:Validity field if the var:VarValue field contains CM_NO_VALUE_YET. |
CM_NO_CONNECTION | Communication with the device is incorrect (due to bad settings, or connected to the wrong device), or is receiving no information at all. |
CM_NO_DATA | The device is communicating with the driver properly, but cannot supply the value requested. |
CM_NO_SENSOR | The device requires a certain sensor which is not connected to the device. If the device cannot generate this specific message, the CM_NO_DATA message is generated. |
CM_NO_MODULE | The device requires a certain module which is not connected to the device. If the device cannot generate this specific message, the CM_NO_DATA message is generated. |
CM_OUT_OF_RANGE | The value is not within certain limits (either user set or hardware defined). If the device cannot generate this specific message, the CM_NO_DATA message is generated. |
CM_UNKNOWN_VARIABLE_ID | The device does not recognize the requested parameter. This does not indicate that the parameter is invalid, only that the driver cannot request the parameter from the medical devices it was designed for. |
Ventilator modes
Value | Meaning |
---|---|
CM_VENTMODE_SPONT | Spontaneous respiration without mechanical help |
CM_VENTMODE_CPAP | Spontaneous respiration with Continuous Positive Airway Pressure |
CM_VENTMODE_BIPAP | Spontaneous respiration with Biphasic Positive Airway Pressure |
CM_VENTMODE_IPPW | Intermittent Positive Pressure Ventilation |
CM_VENTMODE_CMV | Continuous Mandatory Ventilation |
CM_VENTMODE_IRV | Intermittent Positive Pressure Ventilation with longer inspiratory than expiratory phases |
CM_VENTMODE_IMV | Intermittent Positive Pressure Ventilation with pauses between breaths to permit spontaneous respiration |
CM_VENTMODE_SIMV | Synchronized Intermittent Mandatory Ventilation |
CM_VENTMODE_INSP_ASSIST | Assisted Ventilation during the inspiratory phase |
CM_VENTMODE_PRESS_RELEASE | Ventilation in which airway pressure is maintained at a nominal value and intermittently released to permit expiration |
CM_VENTMODE_PSV | Assisted Ventilation with increased airway pressure following initiation of the inspiratory phase. Increased pressure may be maintained at the end of expiration. |
CM_VENTMODE_MMV | Intermittent Positive Pressure Ventilation set to guarantee delivery of a Mandatory Minute Volume |
CM_VENTMODE_PROP_ASSIST | Spontaneous respiration in which the patients breathing is assisted by increasing airway pressure in proportion to their inspiratory effort |
CM_VENTMODE_HFV | Ventilation at rates greater than 60 breaths/min. using HFJV or HFO |
CM_VENTMODE_HFJV | Jet Ventilation at frequencies between 60 and 240 cycles/min |
CM_VENTMODE_HFO | Ventilation at frequencies between 480 and 2400 cycles/min |
CM_VENTMODE_PEEP | Positive End-Expiratory Pressure applied during Intermittent Positive Pressure Ventilation |
Infusion pump modes
Value | Meaning |
---|---|
CM_PUMPMODE_NOMINAL | The pump is in the nominal mode. It may be operated manually or computer controlled and reports flow rates and status information. |
CM_PUMPMODE_DELAYED | The pump is programmed to start infusing after a programmed delay interval or at a specific time of day. |
CM_PUMPMODE_MULTI_STEP | The pump is pre-programmed to several infusion rates and sequentially stepped through. |
CM_PUMPMODE_TITRATION | The infusion rate is increased or decreased in order to keep some physiological parameter constant. |
CM_PUMPMODE_BOLUS_DOSING | A pre-programmed bolus (small volume fast infusion) rate and time or bolus volume/dose exists, which can be delivered to reach some physiological effect. |
CM_PUMPMODE_DRUG_DOSING | The infusion rate is chosen in drug units in relation to some physical parameter of the patient, mass (weight) or surface area. |
CM_PUMPMODE_MULTI_DOSING | The pump is programmed to infuse doses of a drug (boli) in regular periods. Amount of drug, interval between doses (boli) and number of doses is pre-programmed. |
CM_PUMPMODE_RAMP_TAPER | The Pump is programmed to speed up infusing from an initial rate to a plateau rate during a defined ramp time duration or with a defined ramp steepness, stays in steady state at plateau rate for a programmed duration and tapers down to a final rate with defined steepness or duration of taper down |
CM_PUMPMODE_PCA | The pump starts with an initial bolus dose and switches to a continuous dose (maintenance level). The patient has the possibility to request additional bolus doses on demand. The pump can override the requests according to some rule, for example, minimum interval between boli, maximum dose over some interval. |
CM_PUMPMODE_MULTI_CHANNEL | This mode allows the pump to infuse a group of drugs in specific sequence. |
CM_PUMPMODE_CLOSED_LOOP | The infusion rate is automatically adjusted based on some external parameter or physiological effect. |
CM_PUMPMODE_CIRCADIAN | The infusion rate is profiled based on a 24 hour cycle. |
CM_PUMPMODE_KVO | The pump is infusing fluid at a very low rate, to keep vessels open. |
CM_PUMPMODE_TCI | The pump is giving a target controlled infusion in order to achieve a user-defined drug concentration in a body compartment of interest or tissue of interest. |
Infusion pump status
Value | Meaning |
---|---|
CM_PUMPSTATUS_INACTIVE | The pump is inactive. No drug is currently being delivered. |
CM_PUMPSTATUS_INFUSING | The pump is delivering high flow rate after a demand, for example, in PCA mode. |
CM_PUMPSTATUS_KVO | The pump is infusing fluid with an individually set rate. |
CM_PUMPSTATUS_BOLUS | The pump is infusing fluid at a very low rate, to keep vessels open. |
CM_PUMPSTATUS_PCA_GOOD | The patient demand for a bolus in PCA mode is granted by the pump. |
CM_PUMPSTATUS_PCA_BAD | The patient demand for a bolus in PCA mode is rejected by the pump because of rejection criteria, for example, interval between boli. |
CM_PUMPSTATUS_RAMP_UP | The pump is speeding up fluid rate linearly to reach a higher level in Ramp and Taper Mode. |
CM_PUMPSTATUS_TAPER_DOWN | The pump is tapering down fluid rate linearly to reach a lower level in Ramp and Taper Mode. |
