Catheter PRDWho What Where When Why & How
• Who is using the catheter?• Who is it being used on?• What procedures?• What are the indications? contraindications?• What are the sizes or dimensions?• When is it used?• How is it sold?sterile, non sterile, 6’s, 10’s• What other devices is it used with or
compatible with?• What does it do?• What quality or manufacturing tests may be
important? Try to list 3• What standards exist? ASTM, ISO, ANSI

Homework Assignment
• Define & Provide Example(s), if possible, with your catheter and consider for PRD– Accuracy– Actual Value– Deviation– Nominal– Range– Resolution

Catheter ComplaintHazard/Risk/Solution
• Risk Analysis– Identify the hazard– What is the risk? Estimate risks– Where or when did it happen?
Company, Hospital, Doctor, Surgery• Risk Evaluation—determine/decide risk acceptability• What do I do about it?
CAPA (Corrective Action & Preventative Action)• Recall• Do more tests• Change specifications or label/instructions• Nothing but Monitor• Nothing

Severity Level
Description
S1 Neglible; Little or no potential to injuryS2 Marginal; Potential to InjuryS3 Critical; Potential of death or serious injuryS4 Catastrophic; Multiple deaths or serious injury
Risk Level
Risk Acceptability
R1Broadly acceptable, no need to consider further risk reduction
R2Risk is unacceptable and should be reduced as low as reasonably pracricable (ALARP); both economic and technical practicability are balanced against risks/benefits
R3Same as R2 except risk is reduced even at considerable costs
R4 Unacceptable; risk MUST be reduced
