Airway management emt practice test6/15/2023 they are at risk of hypercapnic respiratory failure - often referred to as type 2 respiratory failure). In a subgroup of patients with COPD, high concentrations of oxygen may depress breathing (i.e. Nevertheless, all critically ill patients should be given oxygen. The specific treatment of respiratory disorders depends upon the cause.Feel the chest wall to detect surgical emphysema or crepitus (suggesting a pneumothorax until proven otherwise).pneumothorax, lung fibrosis or pleural fluid). Check the position of the trachea in the suprasternal notch: deviation to one side indicates mediastinal shift (e.g.Auscultate the chest: bronchial breathing indicates lung consolidation with patent airways absent or reduced sounds suggest a pneumothorax or pleural fluid or lung consolidation caused by complete obstruction.Percuss the chest: hyper-resonance may suggest a pneumothorax dullness usually indicates consolidation or pleural fluid.Stridor or wheeze suggests partial, but significant, airway obstruction. Listen to the patient’s breath sounds a short distance from his face: rattling airway noises indicate the presence of airway secretions, usually caused by the inability of the patient to cough sufficiently or to take a deep breath.If the patient is receiving supplemental oxygen, the SpO2 may be normal in the presence of a very high PaCO2. The pulse oximeter does not detect hypercapnia. Record the inspired oxygen concentration (%) and the SpO2 reading of the pulse oximeter.in acute severe asthma or a tension pneumothorax) note the presence and patency of any chest drains remember that abdominal distension may limit diaphragmatic movement, thereby worsening respiratory distress. Note any chest deformity (this may increase the risk of deterioration in the ability to breathe normally) look for a raised jugular venous pulse (JVP) (e.g.Assess the depth of each breath, the pattern (rhythm) of respiration and whether chest expansion is equal on both sides.A high (> 25 min -1) or increasing respiratory rate is a marker of illness and a warning that the patient may deteriorate suddenly. Look, listen and feel for the general signs of respiratory distress: sweating, central cyanosis, use of the accessory muscles of respiration, and abdominal breathing.acute severe asthma, pulmonary oedema, tension pneumothorax, and massive haemothorax). Take bloods for investigation when inserting the intravenous cannula.ĭuring the immediate assessment of breathing, it is vital to diagnose and treat immediately life-threatening conditions (e.g.
