Techniques to monitor the respiratory system during mechanical ventilation have evolved significantly over the years. When integrated with the physical examination, these tools aid the management of respiratory disease, ultimately leading to safer and more effective care for all mechanically ventilated critically ill patients. Respiratory monitoring tools allow for titrating therapeutic interventions to the patient’s disease state, if used correctly can facilitate optimal respiratory support and aid in weaning to extubation. With close monitoring, aberrations or changes in physiologic states can be detected before disease progression, allowing for early interventions and prevention of worsening disease.
Paramount to optimal management is not only selecting the correct mode and ventilator settings for the underlying disease (e.g. ARDS, COPD, Asthma, broncho-pleural fistula), but also monitoring physiologic changes that occur from the disease state, or in response to therapeutic interventions. Monitoring respiratory mechanics is essential to reduce complications related to mechanical ventilation and to monitor recovery from respiratory failure. In intensive care, common means of respiratory monitoring used are work of breathing measurements, and flow-volume and pressure-volume loops.
The availability of ventilator graphics and waveform analysis has had a tremendous impact on the science of mechanical ventilation. Through the analysis of these pressure, volume an flow waveforms, intensive care physician can now more accurately assess not only the current state of lung function but the status of patient-ventilator interaction as well.
