🎯 Key points for quick navigation: 00:36 *🫁 Basics of respiratory regulation* - Lungs impact extracellular fluid CO2 levels. - Breathing frequency affects CO2 levels in extracellular fluid. - Higher ventilation reduces CO2 levels, while lower ventilation increases CO2 levels in the body. 05:34 *🫁 Influence of metabolism on CO2 levels* - Metabolism affects CO2 production. - Higher metabolism leads to increased CO2 and vice versa. - Understanding how metabolism impacts CO2 levels is crucial in respiratory regulation. 10:26 *🫁 Impact of ventilation on pH levels* - Ventilation affects hydrogen ion concentrations. - Changes in ventilation can lead to alterations in pH levels. - Maintaining a balance between ventilation and pH levels is essential for overall health. 23:31 *🫁 Respiratory Control Efficiency* - The respiratory control's efficiency in regulating hydrogen ion concentration ranges from 50% to 75%. 27:20 *🛡️ Role of Respiratory Regulation* - Respiratory regulation acts quickly with an efficiency of 50% to 75% in normalizing pH levels. - The respiratory system is a potent and fast aspect of the body's buffering system. 29:28 *💨 Pulmonary Function and Acidosis* - Conditions like pulmonary emphysema can lead to respiratory acidosis due to impaired CO2 removal. - Enlargement and destruction of distal airspaces in emphysema inhibit proper gas exchange, leading to increased CO2 levels in the blood.

La primera línea de regulación ácidobasica es la de los buffers, amortiguadores o tampones químicos, no el sistema renal @mddanielrodriguez

Así es. Es importante resaltar esto. Posteriormente podemos decir que a corto plazo (minutos) el sistema respiratorio es la segunda linea y por último a largo plazo (horas o días) el sistema renal.
