Harvest the cucumbers when young. Slicing cucumbers should be about 6 to 8 inches (15.24 to 20.32 cm) long. Cucumbers can usually be twisted off the vine without the use of shears. Pickling cucumbers should be harvested at 2 inches (5 cm) and dills should be harvested at 4 to 6 inches (10 to 15.24 cm).
Assist-Control Ventilation (ACV) Also known as continuous mandatory ventilation (CMV). Each breath is either an assist or control breath, but they are all of the same volume. The larger the volume, the more expiratory time required. If the I:E ratio is less than 1:2, progressive hyperinflation may result.
A negative pressure ventilator, often referred to colloquially as an iron lung, is a form of medical ventilator that enables a person to breathe when normal muscle control has been lost or the work of breathing exceeds the person's ability. Examples of the device include both the Drinker respirator, the Emerson respirator, and the Both respirator. The negative form of pressure ventilation has been almost entirely superseded by positive pressure ventilation or negative pressure cuirass ventilation.
