Study Notes

Chris discusses the utility and measurements of capnography in relation to cellular metabolism using the example of a power plant and the human body's metabolic regulators, such as the thyroid.
Low metabolism in severe hypothyroidism can be identified by a squiggling ST segment, low heart rate, and low core temperature in an ECG.
The thyroid, an often underappreciated endocrine system, regulates metabolism and can be affected by medications and surgeries.
Kidneys are responsible for maintaining the body's bicarbonate buffering system and must function properly to prevent a metabolic acidosis.
In a hypermetabolic state, such as in an agitated patient, they may breathe rapidly, producing excess carbon dioxide, and have hypertension.
During CPR, it's crucial to consider the patient's metabolic status and previous respiratory rate before providing ventilation.
In diabetic ketoacidosis (DKA), a metabolic acidosis occurs due to bicarbonate depletion, which affects the body's ability to remove hydrogen ions and regulate pH levels.
Symptoms of DKA include dry skin, fruity breath, and potential volume depletion. Treatment includes addressing hypoglycemia and maintaining renal perfusion.
Sepsis, an overarching attack on the body, can lead to metabolic acidosis, which in turn can cause cardiovascular issues, capillary leaking, and third spacing.
Septic patients can experience increased heart rates and dilated blood vessels due to the body's response to the infection.
Maintaining profusion, or end organ perfusion, is crucial for septic patients to improve their chances of survival.
Fluid resuscitation, such as administering boluses, can help maintain profusion and support the body's metabolic demands.
Contractility, or the heart's ability to pump effectively, should be addressed later in the treatment process to avoid increasing the metabolic demand on the body.
Adrenaline or epinephrine can be used to help maintain and support the circulation in septic patients.
The goal for treating septic patients is to restore end organ profusion and help the body fight the infection effectively.
Early antibiotic administration, along with fluid resuscitation, is essential for improving septic patient outcomes.
