Hyperbaric oxygen therapy
- 1. Preparing patients for Hyperbaric Therapy Aby Chacko Thomas Clinical Instructor SDU Farwaniya Hospital abychackothomas@icloud.com
- 3. Objectives By the end of this class participants will be able to; define Hyperbaric oxygen therapy enumerate the mechanism of HBOT identify the types of HBOT describe the indication and contraindication of HBOT list down the side effects of HBOT explain Nurses responsibilities of HBOT. abychackothomas@icloud.com
- 4. Introduction Hyperbaric Oxygen Therapy (HBOT) is a means of providing additional oxygen to body tissues, by intermittently increasing the amount of oxygen in the tissues, thereby enhancing the healing process. The therapy is painless and has the potential for good results for certain medical conditions abychackothomas@icloud.com
- 6. Definition Hyperbaric oxygen therapy (HBOT) is an inhalation of 100% oxygen at pressure greater than atmospheric pressure. abychackothomas@icloud.com
- 8. Indications Difficult to heal wounds Diabetic foot ulcers Long term side effects of radiotherapy problematic skin grafts Chronic bone infections. Air or Gas Embolism Carbon Monoxide Poisoning Compartment Syndrome / Crush Injury / Other Traumatic Ischemia’s Cerebral Palsy CVA Migraine Multiple Sclerosis abychackothomas@icloud.com
- 9. Indications Skin Grafts and (Compromised) Flaps Thermal Burns Sensory neural hearing loss Near Drowning Recovery from Plastic Surgery Sports Injuries Stroke Traumatic Brain Injury Exceptional Blood Loss (Anaemia) Gas Gangrene Intracranial Abscess Necrotizing Soft Tissue Infection Osteo radio necrosis and Radiation Tissue Damage Osteomyelitis (Refractory) abychackothomas@icloud.com
- 11. Contraindications Absolute Pneumothorax Relative Cardiac Disease COPD with air tapping Emphysema with Co2 retention History of thoracic surgery Malignant diseases abychackothomas@icloud.com
- 12. HOW DOES HYPERBARIC OXYGEN THERAPY WORK? 'Hyper' means increased and 'baric' relates to pressure. Oxygen makes up 21% of the atmosphere air that we breathe. During HBO the patient breathes 100% oxygen intermittently, usually through a hood or mask, while inside a pressurised chamber. abychackothomas@icloud.com
- 13. Breathing 100% oxygen under pressure causes oxygen to be dissolved into plasma. By intermittently increasing the amount of oxygen in the tissues, the healing process is enhanced. HBO can encourage new growth of capillaries, increases the ability of the body to fight infection and kill bacteria, and can reduce swelling as well as other effects. abychackothomas@icloud.com
- 16. Types of HBOT Monoplace Monoplace chambers are designed to treat a single person pressurized with 100% oxygen. Multiplace Multiplace chambers are designed to hold several people at one time and oxygen is delivered through a mask, head hood or endotracheal tube. abychackothomas@icloud.com
- 19. Kuwait football team getting Hyperbaric Oxygen Therapy abychackothomas@icloud.com
- 21. Side Effects Barotrauma to the ears and sinuses caused by the change in pressure. Oxygen Toxicity (Rare case) Changes in vision: this can occur as a result of multiple treatments abychackothomas@icloud.com
- 22. Patient Preparation Educate the Patient about the benefits and side effects of HBOT Provide psychological support if he/she is anxious Check RBS (should be more than 10mmol/L) and vital signs prior to therapy Patient must wear clean cotton(100%) clothing inside the chamber. The technician needs to know if any medications, including non-prescription drugs, are being taken by the patient, Teach the techniques for adequate clearing of the ears (Valsalva maneuver) abychackothomas@icloud.com
- 23. Avoid cosmetics, perfumes, hair preparations, deodorants, or jewellery in the chamber. Lighters/matches Cigarettes Newspapers Perfume/aftershave Hairspray/oil Nylon clothing Ointments/liniments Make-up/nail varnish Wigs/hairpieces Watches Petroleum/Vaseline products Hearing aids, Fountain Pens, Hard Contact lenses, Heat Pads, Hand Warmers Metal-Framed Spectacles Cosmetics Eat a meal before treatment, especially if you have diabetesabychackothomas@icloud.com
- 25. Techniques for adequate clearing of the ears As soon as the air flows into the chamber patient need to start making ears ‘pop’. The easiest method of clearing the ears is to try to very gently blow through nose while holding the nose and lips tightly closed, Moving lower jaw from side to side or an in or out motion abychackothomas@icloud.com
- 26. Nurses Responsibilities Maintain checklist for oxygen supply and air cylinder Verify the written consent form during each session Prepare patient trolley with 100% cotton bed sheets and gown Make sure of emergency breathing apparatus Make sure the microphone is properly working inside and outside the chamber Observe patient safety measures strictly before entering the chamberabychackothomas@icloud.com
- 27. Nurses Responsibilities Start the session under the supervision of doctor and record patient data including past medications Observe the patient for any discomfort before and during session Record the data in nursing notes with date and time Observe the patient for any complications like hypoglycaemia, giddiness after the session Close the chamber after proper cleaning abychackothomas@icloud.com
