CVRESP Week 3: From Airflow to Acid Base to Autonomics

Описание: This video is the third installment in a three-part CVRESP series and delivers a high-yield, mechanism-driven review of respiratory physiology, acid–base balance, and autonomic cardiovascular pharmacology, emphasizing how ventilation, gas exchange, neural control, and drug effects integrate into predictable clinical and exam patterns.

Rather than memorizing isolated formulas or receptor lists, this review focuses on physiologic logic: how lung mechanics determine airflow and resistance, how ventilation–perfusion gradients shape oxygen delivery, how carbon dioxide transport links directly to acid–base regulation, how altitude and exercise stress the system in patterned ways, and how autonomic receptors and cardiovascular drugs manipulate the same core pathways.

Topics covered (in order) include:

• Lung volumes and capacities, and what spirometry can and cannot measure
• Obstructive vs restrictive physiology and compliance patterns
• Laplace’s law and surfactant mechanics
• Airway resistance and small-radius effects
• Pulmonary vascular resistance and the U-shaped curve
• V/Q gradients (apex vs base), dead space, and shunt physiology
• Oxygen dissociation curve shifts and tissue unloading logic
• CO₂ transport and bicarbonate buffering
• Central vs peripheral chemoreceptor control of breathing
• Exercise physiology and anaerobic threshold transitions
• Altitude adaptation: hyperventilation, renal compensation, 2,3-BPG, and polycythemia
• Decompression sickness and Henry’s law
• Acid–base analysis: respiratory vs metabolic disorders, compensation rules, anion gap logic
• Mixed disorders (including aspirin toxicity)
• Autonomic pathways: cholinergic vs adrenergic signaling
• Receptor physiology (α1, α2, β1, β2, M2)
• Baroreceptor reflex integration
• High-yield cardiovascular drugs: dobutamine, amlodipine, verapamil, nitroglycerin, digoxin

Moose Med is a medical-student-run review channel focused on breaking down complex systems into clear, integrated, mechanism-based explanations. The emphasis is always integration before memorization building frameworks that connect ventilation, perfusion, acid–base physiology, neural regulation, and pharmacology into one coherent system.
