Presentation Transcript

  1. Oxygen Rx apparatus • 2 broad classification: • Fixed performance mask • Variable performance mask

  2. Fixed performance mask • FiO2 – ‘Fixed’ and constant • 24%, 28%, 31%, 35%, 40%, 60% • High flow (>PIFR) • No risk of CO2 retention • Easier to monitor patient progress • Uncomfortable, poor patient compliance

  3. Fixed performance mask

  4. Fixed performance mask

  5. Fixed performance mask 40% Oxygen - 40 l/min Air - 29 l/min Oxygen - 10 l/min

  6. Variable performance mask (medium concentration) • FiO2 variable • patient • breathing pattern • Usually supplies 30-60% oxygen (4-10 l/min) • If RR high, FiO2 tends to be lower • Risk of CO2 rebreathing • fresh O2 flow < 4L/min

  7. Variable performance mask (medium concentration)

  8. Variable performance mask(high concentration) • Reservoir bag (non rebreathing mask) • increased FiO2 (10-15 l/min) • risk CO2 retention if <10 l/min • Sometimes called ‘100% oxygen’ mask

  9. Variable performance mask(high concentration)

  10. 100% Oxygen

  11. Nasal cannula • Variable performance - FiO2 unknown • 25%-40% (flow rate 1-4 l/min) • Advantages: • No CO2 retention • Comfortable, high patient compliance • Disadvantage: • Only for mild to moderate hypoxaemia

  12. Nasal cannula

  13. 35y male brought in by ambulance. Unresponsive. BP 160/90. P 110. Needle puncture marks in arms. Given 60% Oxygen on arrival.

  14. After intervention by the very clever doctors……

  15. 65 male with Acute MI… Breathing room air

  16. 6 hours later on 5l/m O2 via simple facemask ….

  17. 12h later on 8 l/m O2 via facemask and treatment……

  18. 22y female asthmatic & SOB.

  19. 3 hours later

  20. 6 hours later

  21. In ICU

  22. A patient with COAD is admitted with SOB

  23. Treated on the ward 5l/m simple facemask ……..(by a doctor who missed Dr Khaw’s lecture !!)

  24. FiO2 - 24% Ventimask

  25. FiO2 - 28% Ventimask

  26. 77y female admitted with ‘IO’

  27. 6h later breathing room air (4 hrs after examination by medical students….)

  28. Post op in ICU……

  29. 19y girl found confused and drowsy…given 60% Oxygen on arrival

  30. Post treatment ….

  31. Discharged on insulin • Three weeks later readmitted with fever, vomiting and lethargy. • …had not taken insulin as she had not been able to eat for 2 days.

  32. 6 hours later…quite unwell
