Effects of atmospheric pressure conditions on flow rate of an elastomeric infusion pump.
The effects of pressure conditions, both hyperbaric and hypobaric, on the flow rate of an elastomeric infusion pump were investigated. ⋯ The flow rate of the Infusor elastomeric pump was not affected when the balloon reservoir and restrictor outlet were at the same pressure. The flow rate varied from 58.54% to 377.04% of the labeled flow rate when the pressure applied to the reservoir varied from 20 kPa below to 150 kPa above the pressure applied to the restrictor outlet, respectively. The maximum difference between observed flow rates and those calculated by applying fluid mechanics was 4.9%.

ReviewSafety and efficacy of glucagon for the relief of acute esophageal food impaction.
The safety and efficacy of i.v. glucagon for the relief of acute esophageal food impaction were evaluated. ⋯ Based on the available data, the use of i.v. glucagon for the relief of acute esophageal food impaction is not supported by the literature. In addition, glucagon has the potential to cause adverse effects and decrease the likelihood of spontaneous resolution.
