Evaluation of a ventilator with fixed volume control and variable regulated pressure

A study of chloroform anaesthesia in a precision system: I The effect on anion-catlon balance in man

“…3, 4, 5). DISCUSSION The minor alterations accompanying chloroform-N~O anaesthesia which were observed during this study were almost identical to those seen in a similar study in which trichlorethylene-N20, halothane-N~O, and the azeotropic mixture of halothane-ether were used (7,8,9). On the basis of anion-cation balance, therefore, no difference is evident ,between these three agents as long as adequate pulmonary ventilation is assured throughout the period of administration of chloroform anaesthesia.…”

“…later in the recovery room. They were analysed immediately for pH, total COs, haematocrit value, and in most clases, for oxygen saturation, employing standard laboratory techniques t h a t Were described in previous reports (7,8,9). Plasma CO2, pCO2, plasma bicarbonate, and fixed acid changes were calculated from the above data.…”

The changing pattern of anesthesia, 1954-2004: a review based on the content of theCanadian Journal of Anesthesia in its first half-century

“…63 Many ventilators were introduced as a result of the introduction of curare in 1942 and the respiratory effects of the poliomyelitis epidemics of the early 1950s. Of ventilators referred to in the Journal in the 1960s, [64][65][66] that invented by Dan Revell 67 may be noted because he worked in Winnipeg and later in Victoria. Epidemics of poliomyelitis stimulated ideas on respiratory care of medical patients with ventilators, and the very first issue of the Journal noted the role of the anesthesiologist in managing respiratory poliomyelitis.…”
