HIGH AND LOW FLOW OXYGEN DEVICES
- 1. NON INVASIVE VENTILATION LOW AND HIGH FLOW OXYGEN DEVICES Unnikrishnan.sv90@gmail.com 9995274650
- 2. NON INVASSIVE VENTILATION WHAT IS NON INVASSIVE VENTILATION ?
- 3. ADVANTAGES • Avoids intubation • Reduces patients work load • Provides adequate oxygen • Improves quality of sleep • Allows patient to communicate • Allows patient to drink and eat • Reduces the chance of infection • Inexpensive
- 4. uses • Weaning trial • A/C Respiratory failure • Neuro muscular diseases • Copd • Pulomonary edema • Bronchiectasis • Poliomyelitis • Muscular dystrophy etc ..
- 5. Contraindications • Respiratory arrest • Uncoperative patients • Inability to protect airways • Trauma or burns in face • Facial or GI Surgery • Apnoea • Extreme anxiety • Obesity
- 6. Types of non invasive ventilators • Generally classified into 2 1. Volume pre set ventilators 2. Pressure preset ventilators Pressure pre set ventilators 2 modes • CPAP • BiPAP
- 7. NURSING RESPONSIBILITY • Check patients breath rate and ausculate • Maintain spo2 100% • Inform the physician regarding any abnormality in ABG Values • Always check for air leake • Give more importance to patients needs like suctioning ,or giving sputum cups if secretions are present • Maintain a ABG CHART
- 8. Complications of CPAP and BiPAP • Insufficient ventillatory support • Mask leake • Skin trauma • Sputum retention • Nutritional deficiencies • Abdominal discomfort
- 9. OXYGEN DELIVERY METHODS /SYSTEMS • 2 SYSTEMS • LOW FLOW DELIVERY SYSTEMS • HIGH FLOW DELIVERY SYSTEMS
- 10. LOW FLOW OXYGEN DEVICES • NASAL CANNULA • SIMPLE FACE MASK • PARTIAL REBREATHER MASK
- 11. HIGH FLOW DEVICES /SYSTEMS • TRANS TRACHEAL CATHETRES • VENTURI MASK • AEROSOL MASK • TRACHEOSTOMY COLLARS • T –PIECE • NON REBREATHING MASK WITH RESERVOIR AND ONE WAY VALVE • HIGH HUMIDITY FACE TENTS
- 12. Formula for calculating percentage of Fio2% • Fio2= 20% + (4 X oxygen liter flow) • 1 liters = 24 % • 2 liters =28 % etc
- 13. • Suppose if we deliver 6 litres of oxygen per min ,what is the Fio2 • ANS- Fio2 = 44% with 6 litres of O2 P/M
- 14. NASAL CANNULA • Flow rate - 2-6 litres per min • 24-45 percentage • Advantage – light weight ,comfortable,inexpensive and continuous use with meals and activity. • Disadvantage – nasal mucosa drying
- 15. Nasal cannula
- 16. Oropharyngeal catheter • Flow rate – 1-6 Litres • Deliver 22-44 % • Adv – inexpensive and no need for tracheostomy • Dis adv – mucosal drying ,catheter should be changed frequently to both nostrils
- 17. Oropharyngeal catheter /air way.
- 18. Simple face mask • Flow rate – 6-8 Litres • Deliver 40-60% • Adv – inexpensive and simple to use • Dis adv – mucosal drying ,poor fitting
- 19. Simple Face mask
- 20. Partial rebreather mask • Flow rate – 8-11 Litres • Deliver 50-75 % • Adv – moderate oxygen concentration • Dis adv – mucosal drying ,poorly fitting , must remove to eat.
- 22. Non rebreather mask • Flow rate – 10-12 Litres • Deliver 80- 100 % • Adv – High oxygen concentration • Dis adv – poorly fitting ,must remove to eat
- 25. Trans tracheal catheter • Flow rate – 4 Litres/min • Deliver 60=100 % • Adv – more comfortable , concealed by clothings ,less o2 is needed to achieve 100% saturation • Dis adv – requires frequent and regular cleaning and needs surgical intervention
- 27. Venturi mask • Flow rate – 4-6 l/min • Deliver 24-40 % • Adv – precise fio2 and additional humidity available • Dis adv – must be removed to eat Colour Fi O2 O2 flow Blue 24% 2 l/min White 28% 4 l/min Orange 31% 6 l/min Yellow 35% 8 l/min Red 40% 10 l/min Green 60% 15 l/min
- 29. Trans tracheal catheter • Flow rate – 4 Litres/min • Deliver 60=100 % • Adv – more comfortable , concealed by clothings ,less o2 is needed to achieve 100% saturation • Dis adv – requires frequent and regular cleaning and needs surgical intervention
- 30. Aerosol mask • Flow rate – 8-10 Litres/min • Deliver 21- 100% fio2 based on nebulizer setting • Adv – good humidity and accurate Fio2 • Dis adv – uncomfortable for some
- 31. Aerosol mask
- 32. Tracheostomy collar • Flow rate – 8-10 Litres/min • Deliver 30- 100 % • Adv – good humidity , comfortable ,fairly accurate Fio2 • Dis adv – requires surgical intervention
- 34. T-piece • Flow rate – 8-10 Litres/min • Deliver 60=100 % • Adv –good humidity , comfortable ,fairly accurate Fio2 • Dis adv – heavy with tubings
- 35. T-piece
- 36. Face tent • Flow rate – 8-10 Litres/min • Deliver 30- 100 % • Adv –good humidity , comfortable ,fairly accurate Fio2 • Dis adv – bulky and cumbersome
- 37. Face tent
- 38. Complications Of Oxygen therapy • Infection • Combustion • Oxygen toxicity • Atlectasis • Retrolental fibroplasis • Retinal damage • Asphyxia
- 39. • Thank you • Count down starts now ………. • Study well ,future of India is in our hands ……..
