Overview
Overview
Hypercarbia means to have more than normal CO2 (Carbon dioxide) levels in the blood.
Pathophysiology
Pathophysiology
- Value is usually obtained while performing a basic Chem-7 blood test, which tests for basic electrolyte levels from a blood sample.
- Normal values of CO2 for anyone over 2 years of age is between 22 and 26 mmol/L.
- Increased levels of serum CO2 are found in some disease processes such as COPD and emphysema and is related to the lung’s decreased capacity for effective gas exchange.
- Hypercarbia has been used to induce NDE-like experiences in patients, and to treat mental disorders.
- VA = (VT-VD) X breaths/min is a formula that can calculate ventilation in the alveolar (VA).
Causes
Causes
- Hypercarbia can be caused by decreased tidal volume (VT), increased dead space (VD), or decreased breaths per minute.
