What could be the causes for basal crepitation?

What could be the causes for basal crepitation?

Lung auscultation?: If you refer to findings while examining breathing sounds with an stethoscope, basal crepitation or crackles could be due to atelectasis ( small desufflated areas of the lung), pneumonia, edema (fluid accumulation), or other lung pathology. ...Read more

Patient 75 yrs  hypertensive diabetic with coarse crepitation and bilateral lower limb oedema 
ECG RBBB
X_RAY cardiomegaly with congestion?

The question?: Hi, what is the question, it seems the patient has a CHF exacerbation with fluid overload, needs evaluation and treatment at the ER or even hospital setting. Also one needs to find out the cause of exacerbation which is usually is non-compliance with medication and diet. ...Read more

How is it possible to have a negative inspiratory reserve volume?

How is it possible to have a negative inspiratory reserve volume?

Pressure vs volume: There is an episode of the Simpsons in which their bodies turn inside out, which is what I would picture happening if one had a negative RV. However, negative inspiratory force (NIF) is a useful tool to assess respiratory muscle strength. Inspiration is an active movement, requiring mainly your diaphragm. In folks with neuromuscular diseases or paralysis, their NIF would be closely monitored. ...Read more

What is inspiratory wheezing?

What is  inspiratory wheezing?

Severe wheezing: Wheezing is typically heard on expiration - when breathing out. Inspiratory wheezing - wheezing when breathing in - usually occurs with severe asthma. Another sound heard on inspiration is called stridor. Stridor sounds like crowing and indicates obstruction around the vocal cords. Severe airway obstruction in croup or laryngospasm generates stridor. Wheezing occurs further down in the bronchi. ...Read more

Can I exercise with inspiratory strider?

Can I exercise with inspiratory strider?

Depends on cause...: If the cause of stridor is viral, as in a bad case of laryngitis, or in a child with croup, then exercise would make the person sicker and might be dangerous. The same goes for bacterial causes of stridor. If the cause is exercise-induced-stridor (eis) or paradoxical-vocal-cord-dysfunction (pvcd) in an otherwise healthy athlete, then exercise is ok but he should get treatment from specialists. ...Read more

What are the inspiratory reserve volume, tidal volume. and expiratory reserve volume?

What are the inspiratory reserve volume, tidal volume. and expiratory reserve volume?

Respiratory volumes: Tidal volume is the amount of air you inspire (bring in) with a normal breath. Usually around 500ml. Inspiratory reserve volume is the max amount you can suck in after a normal inspiration. Expiratory reserve volume is the max amount you can push out after a normal expiration. Vital capacity is the most air you can breathe out after taking the deepest breath in. ...Read more

What is the importance of inspiratory pause for ARDS patients?

What is the importance of inspiratory pause for ARDS patients?

MDT: Mean duration of gas exchange which increases the elimination of co2. Current strategies for ventilation in ARDS include low tidal volumes with rapid respiratory rates and permissive hypercapnia, which leads to a respiratory acidosis in most patients. Increasing the inspiratory pause or including one periodically decreases pac02 by increasing gas exchange time. Survival effects are not studied. ...Read more

In status asthmaticus, what is the cause of inspiratory wheezing?

In status asthmaticus, what is the cause of inspiratory wheezing?

Airway constriction: With any asthma attack, the airway is constricted, which increases the flow velocity and causes the noise, which we call wheezing. Of course the real problem is the increased work of breathing and decreased oxygenation. Medications open the airway, decreasing the flow velocity, reducing the noise and allowing you to breath easier. ...Read more
