I have observed a type of breathing which resembles the Cheyne-Stokes respiration in its first phase, but differs from it in its second phase, thereby constituting a type by itself.
The Cheyne-Stokes type of breathing is usually represented in a graphic manner, as in Figure 1, in which ab corresponds to the period of apnea, which is followed by a series of respirations (bc) at first short and shallow and then gradually increasing in rate and volume until a maximum is reached, after which a gradual return to the apneic state takes place.
The type of breathing which I have observed is graphically represented by Figure 2. In it we have the same apneic state (cb) followed by a gradual increase period (bc); but the period ca (Fig. 1) of gradual decrease is lacking, being replaced by the period of apena, which sets in immediately afther the
