Additionally, the calculations captured the temporal variability and the physical cause of ventilation airflow in the cavities reasonably well.
Ventilated patient characteristics included age, sex, primary reason for ICU admission, comorbidities, date of admission to the hospital and to the ICU, date of intubation and cause of ventilation.
Fourth, pathology that causes absence of ventilation, including severe bronchospasm, patient apnea, or plugged ETT will result in absence of expired carbon dioxide and a falsely negative diagnosis that the ETT is not in the trachea.
Also in accordance with the literature, chronic pulmonary diseases were the most frequent causes of mechanical ventilation in our patients.
The common causes of continued ventilation at 6 h were 'too drowsy' (70%) and 'poor gases' (28%), but at 24 h were 'inotropic support' (86%), 'confusion' (43%) and the use of 'intra-aortic balloon pump' (37%) were cited by the attending nurse.
Acute respiratory failure was the most frequent cause of noninvasive ventilation used (71.3%), followed by pulmonary expansion (10.24%), after mechanical ventilation weaning (6.14%) and sleep obstructive apnea (8.6%).
The cause of the ventilation decompensate has been:respiratory 77,1 %, septic 16,8 %, and miscellaneous in all the other cases.
Acute respiratory failure was the main cause of mechanical ventilation use.
PSV was the principal mode used, while acute respiratory failure was the main cause of mechanical ventilation's use.
The main cause of intubation/mechanical ventilation was acute hypoxemic respiratory failure (35%) followed by depressed level of consciousness (34%), post high-risk surgery (19%), airway obstruction (3%), hemodynamic instability (5%) and respiratory fatigue (01%).
