The foot pump was used to drive a 'Minineb' nebulizer for 10 minutes with 2 ml of solution. It was found that when the operator employed a rate of his own choosing the output varied from 0.9 to 1.9 ml and the oxygen uptake doubled. With a stroke rate of 30/min the output was 1.2 ml and at 60/min 1.4 ml. At 60 strokes/min the average flow rate is 9.1 litres/min which would give a suitable particle size for administration of bronchodilator therapy. It is concluded that the foot pump is useful for occasional use in emergencies as the energy expenditure necessary limits its value in regular therapy and that a fixed stroke rate should be employed.
使用脚踏泵驱动“迷你雾化器”，加入2毫升溶液，持续10分钟。结果发现，当操作人员自行选择频率时，输出量在0.9至1.9毫升之间变化，氧气摄取量翻倍。当冲程频率为每分钟30次时，输出量为1.2毫升；每分钟60次时，输出量为1.4毫升。每分钟60次冲程时，平均流速为每分钟9.1升，这将产生适合支气管扩张剂治疗给药的颗粒大小。得出的结论是，脚踏泵在紧急情况下偶尔使用是有用的，因为所需的能量消耗限制了其在常规治疗中的价值，并且应采用固定的冲程频率。
