Lecture 6 Monitoring Equipment

Question 1

IDC (Indwelling catheter)

Answer 1

• Measures the amount of urine produced

- soft tube that’s placed up the urethra and collects urine from the bladder

Question 2

Nasogastric tube

Answer 2

• flexible tube that goes via nose/mouth and into stomach
• removes bodily fluids from stomach to prevent vomiting/aspiration
• to delive meds/food when the pt is ventilated/can’t swallow

Question 3

Central line/Central venous catheter

Answer 3

• used to deliver fluids/medications (some meds cant be put into peripheral arteries bc they are too toxic so must be put into larger vessels to dilute)
• inserted into large vein (jugular or subclavian)

Question 4

Arterial line

Answer 4

• usually radial (can also be femoral/dorsalis pedis)
• radial line usually splinted to avoid excess movement
• arterial line used for ABG samples

Question 5

Pulmonary Artery Catheter

Answer 5

• balloon tipped flow directed catheter (balloon inflated and put in artery; blood flow pulls balloon and therefore catheter to where it needs to go; then deflated)
• measures pressure at various locations along the way
• used for:
  > Heart Failure
  > Meds delivery
  > optimise fluid rx
  > peri/postoperative surgical procedure with DV/pulmonary dysfunction
  FOR A VERY SICK PATIENT

Question 6

Modifications needed due to PA

Answer 6

• if just had PA catheter removed - delay intervention
• pt generally confined to bed
• monitor changes during treatment

Question 7

PiCCO Monitoring

Answer 7

Pulse Contour Cardiac Monitorying

• continuous
• gives a lot of info about cardiac function
• for a very sick patient
  > used in shock, sepsis, major surgery, cardiac dysfunction, ARDS
• 2 catheters needs - central venous and femoral catheter

Question 8

Name the different types of Respiratory Monitoring

Answer 8

Pulse Oximetry
ABG
EtCO2
Airway pressures

Question 9

EtCO2

Answer 9

• non invasive
• indicator of ventilation
• continuous
• non invasive

Question 10

What are the different types of airway pressures?

Answer 10

1. Peak inspiratory pressure (< 40cmH2O) (max pressure in a set Vt)
2. Mean airway pressure (avg pressure over the entire ventilatory period)
3. End Expiratory pressure (pressure @ end of expiratory phase)
