PHTY300 Lecture Notes - Lecture 3: Sputum, Edema, Respiratory Acidosis
Document Summary
Case studies reasons for intubation and mechanical ventilation. Reasons for intubation: maintain patency of the upper airway. Is upper air(cid:449)a(cid:455)s are(cid:374)"t ope(cid:374) the result is suffocation: protect the lower respiratory tract (cuff between the trachea and outside of breathing tube form a barrier to minimise things going into the lungs) Suctioning (tracheobronchial toilet: allow (invasive) mechanical ventilation. Reasons for mechanical ventilation: provide a gas source. O2 gas movement: replace the function of the respiratory muscles (the pump) Pharmacological paralysis e. g. a full general anaesthetic during abdominal surgery: rest the respiratory muscles. A 36yo male is admitted to icu with 60% burns to his upper body including his chest, face and neck. The burns are a combination of full and partial thickness. Compression on outside of trachea e. g. tumour, haematoma. Patient has burns and this may involve smoke inhalation chemical injury to airway lining inflammation. One of the consequences of inflammation is swelling and oedema.
