PHTY300 Lecture Notes - Lecture 3: Tracheal Tube, Necrosis, Modes Of Mechanical Ventilation
Document Summary
Phty300 week 3 lecture a: effects of intubation and ppv on the cardiorespiratory system. Learning outcomes: discuss the issues and complications of intubation and mechanical ventilation on gas movement, secretion movement, respiratory muscle function and respiratory mechanics, discuss the issues and complications of intubation and mechanical ventilation on the cardiovascular system. Implications for physiotherapy: treatment to prevent/ minimise complications. Damage to vocal cords: increased risk of infection. Nosocomial pneumonia (ventilator associated pneumonia vap: increase in non-gas movement area ( dead space - issue for spontaneous breaths) Minimise the effects of intubation: remove secretions, time with bronchodilator ( gas movement, careful handling of et tube/ head and neck movement, take care with suction, sterile technique, non-traumatic, cuff check: inflated/ pressure, past medical history- awareness. Pulmonary consequences of ppv: compliance of lung (cl) Frc: frc due to: Cephalad displacement of diaphragm = less air to dependant regions: strategies: peep.
