A surgical stapling apparatus (stapler) including a housing, elongated member, and a reload is disclosed. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.

Aspects of this disclosure describe methods and systems for evaluating phrenic nerve integrity of a patient and a ramp-up pulse string for nerve stimulation. Integrity of a nerve may be assessed and therapy may be slowly introduced to the patient. To determine integrity, a nerve is electrically stimulated and a return signal is evaluated. For example, a time lapse and a band width of the return signal may provide information about nerve damage and a location of the nerve damage. In addition to assessing nerve integrity of a patient, a stimulation burst (e.g., an electrical stimulation) may be delivered as a ramped-up pulse string (e.g., a series of pulses with increasing voltages) to achieve smooth breathing. The voltages of a stimulation burst may be increased based on a target tidal volume for the patient. The stimulation burst may be delivered during an inhalation phase of a breath.

In an example, the low-profile humidifier includes a humidifier body that includes a liquid port; a pump in fluid communication with the liquid port; a valve in fluid communication with the pump; a nozzle in fluid communication with the valve; a controller that controls the valve and the pump. The low-profile humidifier also includes a removable flow channel that is removable from the humidifier body. The removable flow channel includes a gas inlet sized for connection to a conduit from a medical ventilator; a gas outlet; a conduit between the gas inlet and the gas outlet; a heated surface within the conduit to vaporize liquid droplets injected by the nozzle; and a through hole to receive the nozzle into the conduit.
