Mechanical ventilation provides positive pressure of larger airways and premature collapse of bronchioles and stabilizes alveoli.complication are barotruama rupture of lungs bleeding.vq scans available from PE.
Dead space means that part of airways which do not take place in gas exchange o2 and co3.anatomical DS includes upper airways +those bronchioles which do not take place in gas exchange.that,s the reason fr reducing dead space by opening up trachea.
Pulm embolism is type 1 failure hence hypoxic failure. Type failure however may slip to type 2.hence clinical features of pe resembles hypercapnic breathing.pulmoary edema develops quickly.
Hypercapnia results in a life threatening condition called resp.acidosis. the acid base balance disturbance results in increased production of sodium bicarbonate.if either of the organs fail to compensate.the patient needs artificial ventilation like bipap to treat types I resp failure.type 2 is a hypercapnic resp.failure which needs invaive procedure like traceostomy and attachment to mech.ventillator.

Excellent video!! Thank you very much
Thank you. Excellent way of presenting it for the easement of understanding. 👍👍👍❤️❤️❤️
Glad it was helpful!
Videos like this make me reach for another cigarette
Omg I loled
Hall mark of copd is increased airway resistance /increased work of breathing depending on TV andRR/wasted ventilation and V/qmismatch.

Surgical removal of bullae common in copd helps when increase in dead space
and improves WOB due to more optimal diaphragm placement.

Physiological dead space is more important. It is ADS+those alveoli that do not take part in resp.

I don't think pulmonary edema is hallmark of acute PE
Wasted ventilation results in hypercapnia. Which is compensated by kidneys.

How can you prevent this
early intervention with steroids/bronchodilators +/- Abx + CPAP . stop smoking, gets your appropriate vaccination & avoid airway irritants . . .
Copd is a called in various countries cal chronic airflow obstruction coad chronic obs.airway diese
What is hypercapnia
Elevated partial pressure of carbon dioxide in arterial blood.
