Catheters are thin, flexible tubes that are commonly used in medical procedures. They can be made of silicone or other materials like latex or polymers. Catheters are often required for patients with kidney, bladder, or neurological disorders or during surgical procedures to decrease invasiveness. They are widely used in fields like cardiology, urology, and nephrology. Common types include indwelling catheters, permcaths, and those used for urinary catheterization or hemodialysis. Pulmonary artery catheters are inserted into the pulmonary artery and can measure pressures, oxygen saturation, and cardiac output. Placement sites like the internal jugular, femoral, and subclavian veins each have

5. LITTLE MORE ABOUT
CATHETERS…………
All our Cliny catheters are made from medical
grade silicone which is well known for its
biocompatible properties.
Silicone is "gentle on the body" and less likely
to cause irritation,
OTHER MATERIALS ARE ALSO USED:
LATEX
POLYMERS
METALS(early catheters)

6. WHY CATHETER ARE REQUIRED?
?

7. For a patient who is suffering from a disease of the kidney
or bladder
For a patient who is suffering from a neurological disorder
For diagnosis where high precision level is desired
In surgical process in order to decrease the level of
invasiveness degree
Anesthetic control and infusion
IV line
Catheters are widely used in fields of
cardiology,urology,nephrology ,ENT

9. indwelling catheter: An
indwelling, or Foley catheter is
a thin, flexible drainage tube
that drains body fluid or urine

11. Permcath: A Permcath is a flexible
plastic tube that can be put into a vein
or in required body part for a long
time period.

13. Location Advantage Disadvantage
Internal Jugular • Bleeding can be recognized • Risk of carotid artery puncture
and controlled • PTX possible
• Malposition is rare
• Less risk of pneumothorax
• Easy to find vein • Highest risk of infection
Femoral
• No risk of pneumothorax • Risk of DVT
• Preferred site for • Not good for ambulatory
emergencies and CPR patients
• Fewer bad complications
• Most comfortable for • Highest risk of PTX, should not
Subclavian do on intubated pts
conscious patients
• Should not be done if < 2 years
• Vein is non-compressible

14. NOW CATHETERIZATION
TECHNIQUES…….

15. TYPE OF CATHETERIZATION:
CARDIAC CATHETERIZATION
Central Venous Catheterization
Pulmonary Artery
Catheterization
Urinary catheterization
Coronary catheterization
Hemodailysis catheterization

17. Pulmonary Artery Catheterization

25. Also known as a “Right Heart Catheter”. The position
from distal end to proximal end is: Pulmonary Artery,
Right ventricle, right atrium, vena cava, subclavian vein.

1. Balloon
2. Openings:

b. Proximal
c. Injectate

6. Oximeter

30. Measurements recorded in “mmHg”
These values are a measurement of the fluid
pressure in the Pulmonary Artery, and Vena Cava
respectively. These values are useful in
quantifying and diagnosing cardiopulmonary
disease.

32. SvO2
Saturation of Venous Oxygen
Measured in the Pulmonary Artery
This reading is the Only TRUE mixed
venous.
