Stages of Disease

Hemodynamic instability, generalized edema, and hypoxemia characterize the early stage of the disease.
Mediator-induced disruption of the vascular bed and increasing interstitial and alveolar edema are evident in the intermediate stage.
Progressive lung fibrosis, difficulties in ventilation management, increased airway pressures, and multiorgan involvement occur in the late stage of the disease.

pH Levels

Uncompensated pH levels indicate an acid-base disturbance that the body cannot correct.
Compensated pH levels show that the body has adjusted either Paco2 or HCO3 to stabilize the pH but original disturbance is still present.

pH Level Measurement

The pH level is assessed to determine whether it is above or below 7.40, establishing acidemia or alkalemia.

Ventilation/Perfusion Mismatches

Causes of ventilation/perfusion mismatches include various lung diseases, pulmonary embolism, and conditions affecting air movement or blood flow in the lungs.
Conditions causing low ventilation/perfusion ratios can include severe asthma, pneumonia, and chronic obstructive pulmonary disease (COPD).

Pulmonary Causes of Impaired Lung Integrity

Non-pulmonary causes of impaired lung tissue integrity may include conditions like heart failure or systemic infections, rather than direct lung damage.
