|
|
Tidal volume:6-8 ml/kg body weight
|
|
PEEP is set at 80% of auto-PEEP
|
|
Inhalation time:0.6-1.2 seconds
|
|
Breathing frequency:8-16 breaths/minute
|
Detailed explanation-1: -Pulmonary barotrauma is a frequent complication of PEEP therapy. Pneumothorax, pneumomediastinum, and interstitial emphysema may lead to rapid deterioration of a patient maintained on mechanical ventilation with an already compromised respiratory status.
Detailed explanation-2: -Initial ventilator settings are recommended like that; TV: 6–10 ml/kg, FiO2: 1.0, RR: 10–14 breaths/minute, no PEEP, inspiratory flow rate: 80–100 liter/minute with square waveform [1, 2, 4].
Detailed explanation-3: -The majority of patients with acute respiratory failure due to acute exacerbations of COPD (AECOPD) should undergo a trial of noninvasive mechanical ventilation (NIV) because intubation can be successfully avoided and mortality reduced with this intervention [1-7].
Detailed explanation-4: -Initial settings for ventilation may be summarized as follows: Assist-control mode. Tidal volume set depending on lung status-Normal = 12 mL/kg ideal body weight; COPD = 10 mL/kg ideal body weight; ARDS = 6-8 mL/kg ideal body weight. Rate of 10-12 breaths per minute.
