This video presents: Anatomical and Physiological Dead Spaces Composition of gases in the respiratory zones Composition of gases at the end of inspiration and expiration Minute ventilation rate Alveolar ventilation rate
This video discusses: Atmospheric gas pressures Water vapor pressure and its effect on the atmospheric pressure Pressure changes during inspiration Composition of the exhaled gases Factors affecting partial pressure of the oxygen Factors affecting partial pressure of the carbon dioxide
This video presents: Anatomical and Physiological Dead Spaces Composition of gases in the respiratory zones Composition of gases at the end of inspiration and expiration Minute ventilation rate Alveolar ventilation rate
This video presents: Tidal Volum (TD) Insipratory Reserve Volume (IRV) Expiratory Reserve Volume (ERV) Residual Volume (RV) Inspiratory Capacity (IC) Functional Residual Capacity (FRC) Vital Capacity (VC) Total Lung Capacity (TLC)
This brief video presents: Apneustic breathing pattern Biot/Ataxic breathing pattern Cheyne Stoke breathing pattern Kussmal breathing pattern
This video presents: Pressure dynamics in the alveoli and pleura during the restful breathing cycle. Pleural pressures are discussed at: a) Restful state (breath held) b) Inspiration c) Expiration
This brief video presents: Quite breathing Chest wall mechanics including: Pump handle movement Bucket handle movement Muscles of quite and forced inspiration Muscles of quite and forced expiration
This video presents: Lung Mechanics. Following topics are discussed: Lung environment Inward or recoil forces Outward or expansile forces Terminology to express various pressures Laplaces law Atelactasis Special case of premature babies

This video presents pneumothorax
The following topics are discussed:
- Pleural cavity formation
- Simple Pneumothorax
- Tension Pneumothorax
This video presents: Postivie Pressure Ventilation (PPV) Positive End Expiratory Pressure Ventilation (PEEPV) Advantages and disadvantages of these methods
This video presents: Chest wall compliance Lung tissue compliance Combined compliance of the chest wall and lung tissue Pathological conditions that change compliance.
This video presents the relationship of the flow, pressure, and resistance in the lung airways.
This video presents: Ficks law of diffusion of gases Ficks equation Calcuating oxygen diffusion rate Assessing respiratory interface health
This video discusses: Gas pressure gradient across respiratory membrane Causes of the pressure gradient Capillary diffusion dynamics Adaptation during the exercise
This video discusses: Structure of the Hemoglobin Hb dissociation curve Factors affecting the dissociation curve Oxygen buffering by Hb
This video discusses: Total volume of the carbon dioxide transport to the lungs Three forms of the carbon dioxide transport Chloride shift Carbonic anhydrase Carbon dioxide pressure gradients in the tissue and lungs
This video discusses Bohr Effect Increased carbon dioxide pressure in the tissue helps unload oxygen in the tissues. This is opposite to the Haldene effect where increased oxygen pressure helps unload carbon dioxide in the lungs.
This video discusses: Alveolar ventilation Blood flow through lungs Calculating the ratio Evaluating the V/Q ratio Generalizations
Dr. Mobeen discusses oxygen pressure changes to help load or unload carbon dioxide from the hemoglobin.
Oxygen pressure changes are critical for CO2 movement in and out of the body.
In lungs, we have more oxygen pressure which favors unloading of the carbon dioxide. This will help carbon dioxide eject from the body.
On the other hands in the peripheral tissues oxygen pressure is less. This allows carbon dioxide to be loaded on to the hemoglobin and move away from the tissue.
This video presents the lung function tests.
This video discusses: Control of respiration by a) Chemoreceptors, both central and peripheral. b) Neuronal control c) Respiratory rhythm d) Nerves involved in the respiratory control e) Effect of carbon dioxide and oxygen pressure changes on breathing rate and rhythm
This video introduced the normal protective mechanisms of the respiratoty system. Mechanism introduced are: Protections in the nose, mouth, pharynx, and upper airways Mucocilliary elevator Antibodies Macrophages Moisture on the airway surfaces Etc.
