How do we monitor mechanical ventilation?

Modern ones are easy (show numbers - pressure/ volume/ flow...) Set acceptable parameters limits: Low ventilation ->ventilator disconnection, apnea alarm, high airway pressure alarm [ PIP seen for resistance, it increases in case of parenchymal disease, pneumothorax, obesity, increased abdominal pressure] Lung mechanics (measure Pplat (hold breath at end of expiration - same auto-PEEP) Ventilatory Synchrony (ineffective triggering arrow, common cause is auto-PEEP , airwflow obstruction (bronchospasm) and high ventilation)
