Pulmonary Workload Basics
Pulmonary workload reflects the effort required to breathe and increases when compliance decreases or resistance rises leading to greater energy expenditure and potential respiratory fatigue.
Muscle Demand
Respiratory muscles must generate sufficient force to overcome resistance and maintain ventilation and increased demand can lead to muscle exhaustion.
Workload Indicators
Indicators include accessory muscle use rapid shallow breathing and increased respiratory rate which signal rising respiratory effort.
Workload Measurement
Clinicians assess workload using ventilator data respiratory patterns and patient effort.
Therapeutic Management
Management includes reducing resistance improving compliance and providing ventilatory support when needed.
