Blood  Pressure  Monitor  (Automatic)    Preventative  Maintenance  
Preventive  Maintenance  

• Check  power  supply.   If   the  machine  uses  batteries,   check   their  voltage  and  replace  when  output   is  low.  If  wall  input  is  utilized,  ensure  that  the  proper  power  is  being  used.  • Inspect  power  cords  and  plugs.  Check  AC  plug  for   loose  or  damaged  parts.  Verify  proper  insulation  and  integrity  of  cords.  • Assess   for   leaks,   cracks,   and   occlusions   in   the   cuff,   connections,   and   tubing   inside   and   outside  apparatus.  Inspect  all  fittings  and  connectors.  • Inspect  inside  circuitry.  Verify  that  all  switches  operate  properly  as  well.  • Check  that  any  alarms  go  off  when  the  measured  blood  pressure  is  outside  of  an  acceptably  healthy,  that   is   if   the  NIBP  has   this   capability.   The   clinical   staff   should   establish   this   range.   To   test   this   on  yourself,   set   the  parameters  such   that   they  should  go  off  when  you   take  your  own  blood  pressure.  Once  you  are  assured  that  the  alarms  are  functional,  be  sure  to  set  the  parameters  back!  • Perform  a  self-­‐test  on  the  BP  cuff  to  ensure  cuff  is  working  properly  and  within  reasonably  accuracy  (±5  mmHg).  Accuracy  can  be  determined  by  having  the  clinical  staff  take  your  blood  manually.    
How  To:  Taking  Blood  Pressure  1. Prepare  the  patient.  o Sitting  or  lying  down  o Arm  unobstructed  o Ask  about  blood  pressure  history  o Ensure  that  it  is  a  quiet  space  and  that  the  patient  doesn’t  move  too  much  –  many  NIBPs  are  sensitive  to  noise  and  movement  2. Wrap  the  cuff  around  the  upper  arm  with  leads  facing  the  brachial  artery.  Be  sure  that  it  is  the  proper  cuff  size  for  the  patient’s  arm.  The  cuff  should  be  about  1-­‐2  cm  above  the  elbow  and  about  level  with  the  patient’s  heart.  3. Turn  on  the  machine,  and  press  “start”  when  ready  to  measure  blood  pressure.  4. Have  the  patient  remain  still  and  quiet  until  a  blood  pressure  is  displayed.  Often  times  a  pulse  rate  will  also  be  measured  and  displayed.  5. If  the  patient  has  a  higher  than  usual  blood  pressure,  many  NIBPs  will  allow  the  user  to  hold  the  start  button  until  the  monitor  inflates  30-­‐40  mmHg  higher  than  the  expected  blood  pressure.  6. If  the  cuff  needs  to  be  deflated  or  reset  during  inflation  for  any  reason,  press  the  off  button.  7. Record  the  blood  pressure.   Examples of ranges for healthy blood pressures: Age   BP  (Systolic/  Diastolic)  Child,  <6  months   90-­‐105/70  Child,  6  months  to  7  years   105-­‐117/70  Adult   120/80
