Figure 1 Schematic diagram depicting changes in flow and subglottic pressure during the inspiratory, compressive (COMP), and expiratory phases of cough. CHEST 2006 129, 48S-53SDOI: (10.1378/chest.129.1_suppl.48S) Copyright © 2006 The American College of Chest Physicians Terms and Conditions

Figure 2 Expiratory pressures are reduced with partial curarization (lower panel). Expiratory flows are only mildly reduced, but the peaks in flow are absent with partial curarization.31 CHEST 2006 129, 48S-53SDOI: (10.1378/chest.129.1_suppl.48S) Copyright © 2006 The American College of Chest Physicians Terms and Conditions
