  • It is essential to maintain the blood supply and the function of vital organsHigh blood pressure (hypertension) may indicate coronary heart disease, heart failure, stroke, kidney failure and many other health problemsLow bl pre hypotension my indicate heart problems endocrine or neurological disorders. Or may be an indication of dehydration It can vary with age typically the new born will have a reading of 80/50 while a constant rise will see a young adult have a blood pressure of 120/80, blood pressure as a rule will rise with ageForces. 1 is created by the heart as it pumps blood into the arteries 2 is the force of the arteries as they resist the blood flow
  • Arm is slightly flexed and the cuff placed around the bicep area, most cuffs have arrows pointing showing which where to place the cuff. Place a stethoscope just under the crease of the elbow. Ensuring the screw cap is tight you can inflate the cuff.Inflate the cuff until the radial pulse disappears Slowly unscrew the cap and let the air seep out slowly Listen for when blood passing through the arteris can be heard again and make a note of the number the pressure gauge is at this is the systolic or top number.When the blood can not be heard any more through the stethoscope this is the diastolic reading/ the bottom number
  • The cuff of this meter is placed in the same place as the others, but it digitally inflate and take the appropriate measurements it’s self
  • Transcript

    • 1. MONITORING
      Pulse Oximeter
      ECG
      Blood Pressure
      Arterial Pressure
    • 2. PULSE OXIMETER
    • 3. Pulse Oximeter
      Pulse Oximeter’s have created economical, compact, non-invasive and efficient methods of monitoring both pulse rate and oxygen saturation in the patient.
      How is it Used?
      • Connected to the patient via a small lead, attaching to a probe usually to the index finger or ear lobe.
    • How does it work?
      • Oxygenated haemoglobin and deoxygenated haemoglobin have different absorbable colours at different light wavelength.
      • 4. Comparison of absorbencies at different wavelengths leads to an estimation of relative concentrations of oxygenated and oxygenated haemoglobin
      • 5. Non-invasive and work regardless of skin pigmentation
      • 6. Provides an overall assessment of the oxygen being delivered to the patients internal and external respiration mechanisms throughout procedures
    • Problems?
      • Been reports of burns, particularly with the prolonged use of finger probes on children
      • 7. The readings can be inaccurate. Inaccurate readings may result due to nail varnish or colouring is present, and if venous congestion occurs
    • ECG Monitoring
    • 8. What is it used for?
      Shows the heart rhythm
      Enables us to read the electrical impulses of the heart
      Gives Heart rate
      Can indicate myocardial Ischaemia (Shields & Werder, 2002)
    • 9. How is it done?
      Usually performed when patient at rest
      Upto 10 ECG sticky pads/self adhesive electrodes are attached on the skin of the arms leg and chest.
      Three lead ECG is most common and the 12 lead ECG gives 12 points of view so heart activity can be accurately analysed.
      (chest may need to be shaved)
    • 10. Normal Sinus Rhythm (NSR)
      According to Wicker & O neil (2006)-
      The sinus node produces an electrical impulse launching a normal heart rhythm
      Signal radiates through right and left atrial muscles producing electrical changes
      stimulating atria causing atrial contraction (P wave)
      Impulse continues through AV node conducting electricity at slower pace (PR interval)
      Pause between atrial and ventricular systole-blood empties from atria into ventricles
      Ventricular contraction (QRS) –blood propels towards aorta and pulmonary artery
      T wave- ventricles relaxing
    • 11. Ventricular relaxation/repolarisation
      Atrial contraction/ depolarisation
      (systole)
      QRS: Ventricular contraction
    • 12. This cardiac cycle repeats to create a rhythm
      Normal Heart rates:
      ADULT 60-80 BPM
      CHILD 100BPM
      INFANT 150BPM
      *Depends on health, mental state and BMI
    • 13. Sinus Bradycardia
      Slow heart rate with normal sinus rhythm
      Can be benign but can be caused by beta blockers, hypothermia, stimulation of the vagus nerve, hypothyroidism etc
      Sinus Tachycardia
      Fast heart rate at normal rhythm
      Caused by shock, drug actions (e.g. Atropine), anxiety, hypovolaemia etc
    • 14. Other Abnormal heart rhythms:
      Supraventricular tachycardia (SVT)
      impulse stimulating heart not coming from Sinus node, instead comes from tissue around AV node. HR up to 280 BPM
      Ventricular tachycardia
      tisues in ventricles casuing rapid irregular Heart rhythm
      Atrial Flutter
      Rapid heart rhythm. Abnormal. Impulse bypasses AV node
    • 15. Other Abnormal heart rhythms:
      Atrioventricular block (AVB)
      Block in conduction between Sinus node and AV node.
      2nd degree heart block- some signals from atria don’t reach ventricles= dropped beats
      3rd degree= AV block means no impulses passing through AV node so ventricles create own rhythm
      Premature atrial contraction (PAC)
      Sinoatrial node fires early= early atrial contraction
      Premature ventricular contraction (PVC)
      Av node fires early- ventricles contract early
    • 16. Other Abnormal heart rhythms:
      Atrial Fibrillation
      Electrical impulses fired irregularly from many sites in atria
      Asystole
      End of heartbeats, lack of electrical activity but not straight line so still some continuing residual activity
    • 17. Blood pressure monitoring
    • 18. Blood pressure - what is it?
      • Adequate blood pressure is essential to the body
      • 19. Blood pressure is the force exerted on the arteries.
      • 20. It results from two forces
    • Blood pressure types of measurement
      Blood pressure cuff manual or
      • aneroid monitor.
    • Types of monitoring
      • The digital reader

    • 21. Arterial pressure monitoring
    • 22. Why is it needed?
      To show beat to beat variation in the arterial trace.
      Other parameters that can be measured.
      Myocardial contractility.
      Vascular tone.
    • 23. When would it be needed?
      Constantly changing clinical parameters in sick patients.
      Blood sampling- helpful multiple samples are needed.
      Acute interventions-major surgery.
    • 24. Where is it used?
      Arm- radial, brachial and axillary arteries.
      Leg- dorsalis pedis, posterior tibialis and femoral.
      Transducer should be positioned level with heart to give accurate reading.
    • 25. How is it measured?
      Transducer energy one form to another.
      Pressure change causes movement within transducer.
      This creates electrical current to be displayed on oscilloscope.
    • 26. Placing the line
      Decide the anatomical site
      Palpate the artery.
      Clean area thoroughly-local anaesthetic?
      Seldinger technique- guidewires can be used to assist in insertion of the cannula up the lumen of the artery.
      Remove the needle, thread a cannula over the wire and up the artery before removing the wire.
    • 27. Mark the arterial line to indicate it presence
      So as not to be mistaken for a venous line
      Ensure there is no air within the line
      Use heparinised saline to flush
    • 28. Complications!!
      Disconnection causing bleeding
      Incorrect injection of drugs
      Arterial occlusion
      Haematoma
      Nerve damage
      Embolis
      Aneurysm formation
