Oxygen therapy

OXYGEN THERAPY

Indications

  • For severe acute respiratory diseases causing hypoxia and hypoxemia
  • For ventilation- perfusion mismatch (Eg. Pneunconia and air by respiration)
  • Supportive care for animals in shock
  • For any disease causing hypoxia
  • Animals with poor ventilation require tracheal intulation and pressure intulation.
  • → Hyperventillation is not an indication for nasal oxygen.

Procedure

  • With nose pointing upwards, 1 ml Lignocaine is instilled into the nostrils. Repeat this after a minute. Measure tubes from external nares to the inner canthus of the eye. Lubricate the catheter with sterile lubricant. Insert it into the ventral nasal meatus to distance already marked on catheter.
  • Apply suture on the skin near the nostrils. Position the tube between  the eyes and secure it at forehead and top of the head. Connect the extension tubing with nasal catheter, liquefy the passage, start administering oxygen.

Rate of Administration of Oxygen

  • 50 – 100 ml / min / kg body wt or 4 litres/min in small animals
  • 12 litres / min in large animal
  • 0.5 litres / min in birds
