Dear Editor,

I thank the reader ^[1] for appreciating our indigenous novel method of giving a "U" turn to infusion tubing to increase the negative pressure that would be required to aspirate air. ^[2] The basic principle of physics behind this technique is that more the length of the "U" more will be the pressure required and hence more the safety. But the length of the infusion tubing is fixed so we are giving a "U" turn of 15 cm of each side. This length adds safety without need of extension tubing. I agree with the reader that the understanding of basic principles is of foremost importance in practice of intensive care and thank for his interest and appreciation.
