Document Summary
Assessment of respiratory system: subjective data, objective data, diagnostic tests. Diagnostic tests: arterial & mixed venous blood gases, arterial blood sample which measures oxygen concentration in the blood (spo2 n: 95 . Cpap continuous positive airway pressure: purpose: to deliver continuous air to assist keeping alveoli open during sleep, nasal cpap delivered through a full or partial face mask or nasal pillows, most commonly used for obstructive sleep apnea. Intubation: placement of tubes to maintain an open airway ex. Use clean technique for oral airways, but use sterile technique caring for and maintaining endotracheal and tracheal airways to prevent health care associate infections (hais). Tracheostomy: tracheotomy: surgical incision into trachea for the purpose of establishing an airway, tracheostomy: the stoma (opening) that results. Used to obtain a closed circuit for ventilation. Cuff should be inflated just enough to allow minimal airleak. Cuff should be deflated if patient uses a speaking valve. Cuff pressure should be checked twice a day.
