Brief Summary
Anesthesia providers are taught to "test" that they can properly ventilate a patient's lungs before administering a neuromuscular blocking drug (NMBD), rendering the patient apneic. This is a traditional teaching, not based on empirical evidence. The investigators primary hypothesis is that ventilation after the administration of NMBDs is non-inferior with that before their administration with respect to the composite safety endpoint of inadequate (MVi) and dead-space only (Vds) ventilation.
