One of our facilities is developing a hyperbaric chamber service. Pharmacy was not initially consulted on this and we recently found out they have bought IV pumps for use in the hyperbaric chambers. Since they are monoplace chambers the pumps have to be able to generate 30 psi or more without alarming. Something most cannot do. The pumps they purchased are Zyno Medical Z-800F pumps. From a DERS standpoint the Zyno pump does not appear to have that capability, which is against our policy. What are others using for pumps in monoplace hyperbaric chambers and if using the Zyno medical pump have you been able to program any safeguards into the pump?
