Hyperkalaemia
Definition Mild hyperkalaemia: >5.5 – 6.0 mmol/L Moderate hyperkalaemia: >6.0 – 7.0 mmol/L Severe hyperkalaemia: >7 mmol/L 💡Tips– Check formal RP result, to look for documentation of ‘haemolysed blood‘ in the formal report. If so, the ‘hyperkalaemia’ might not be reliable and RP should be repeated prior to giving treatment. – Do ECG! If ECG […]
Blood Gas – ABG, VBG
Normal Range Notes: Some blood gas machines can analyse additional parameters such as lactate, Hb, potassium, calcium levels which would be helpful for decision making during emergencies Respiratory acidosis Features in ABGpH <7.35 + pCO2 >45 mmHg + HCO3- >30 mmol/L —–(i) Acute respiratory acidosis – For every 10 mmHg increase in pCO2, HCO3- will […]

Cardiac Ultrasound
Preparation Patient’s position: supinePreset: cardiacProbe: Sector probe, B mode Indications / Uses • Cardiac tamponate• Massive acute pulmonary embolism• Estimation of left ventricular ejection fraction 4 Standard Cardiac Views • Parasternal long axis: 2 – 4th left intercostal space just next to sternum • Parasternal short axis (parallel to long axis of left ventricle): rotate […]
Lung Ultrasound
Preparation • Patient’s position: supine• Preset: lung• Probe: curvilinear B and M mode• Probe position: anterior chest wall mid clavicular line, sagittal plane; R1 / L1 Signs ⚽️ A-lines– Repetitive horizontal artifacts that recur at recur at regular intervals that are equal to distance between probe-skin interface and pleural-subpleural air interface – Not representing any […]
