PCD Infusion Pump WGContainment / Mode / Status

Discussion (rev. 2)

Updated: 2012.04.23 Monday

www.ihe.net2

DS-IP-xyz Containment/Mode/StatusDiscussion Scope:

Review proposed containment models for : DS – Infusion Pump – LVP DS – Infusion Pump – Syringe DS – Infusion Pump – PCA

Define role and values for pump Mode parameter Define purpose and values for pump Status parameter

www.ihe.net3

DS-IP-LVP Containment Model

VMDs are paired with technology-specific delivery channels

Source Channels package semantics that define / drive the behavior of a Delivery Channel

Multiple source channels can be “active” at any point in time.

www.ihe.net4

DS-IP-Syringe Containment Model

Syringe-specific parameters are contained in the Syringe Delivery Channel

Source Channels are the same as those available for LVP Delivery Channels

www.ihe.net5

DS-IP-LVP-PCA Model

PCA specific parameters are packaged in a PCA Source Channel

PCA Source Channel can be combined with other Source Channels as needed

PCA Source Channel can be combined with any Delivery Channel (LVP or Syringe)

PCA Source Channels may operate exclusively, sequentially or concurrently with one or more other Source Channels.

DS-IP-Syringe-PCA Containment Model

Only difference is the choice of the Syringe Delivery Channel “mechanism”

Pump Mode & Status ParametersDiscussion Points:

Operational Mode & Status contained in delivery channels Mode reflects …

what source channels are actively determining the operation of their associated delivery channel

What the user would “see” as the configured “mode” All source channels OR only currently active source channels?

Status reflects … primarily what is observed in the distal line … ?

ISSUE #1: What do we want these values to be for DS-IP-xyz? Including active / concurrent source channel indication

ISSUE #2: Harmonization with the 11073-10101:2004 Definitions

Proposed Resolution Define two Operational Mode parameters + 1 status parameter MDC_PUMP_MODE_SETTING (proposed)

Indicates the configured infusion “protocol” Enumerations include: pump-mode-continuous / -piggyback / -

pca / … Multiple mode “bits” can be set

MDC_PUMP_MODE_CURRENT (proposed) Indicates the actual operational – including simultaneous –

operational modes Enumerations - same as MDC_PUMP_MODE_SETTING

MDC_PUMP_STAT (… can we make this _STATUS?) Indicates what the pumping mechanism is doing Does NOT include alarm status indication (separate parameter) Enumerations include: pump-status-ready / -infusing / -paused /

-delayed / -standby / -off / …
