Choose a spokesperson

All students in the group are to work on all of the following questions/sections included in the Padlet

You can use diagrams/images other visual resources to explain each respiratory condition.

When we come back to the whole class, the spokesperson will feedback the groups findings, with the teams support

Chronic airway inflammatory airway disease causing bronchoconstriction and increased mucous secretion.

Because of swelling of smooth muscles in alveoli, overproduction of mucus which narrows the lumen. This makes expiration harder than inspiration.]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714852 paulinewong1 https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714853 Allergens ----- activation of immune response---release inflammatory mediators
cause
1) Inflammation of lower airway--secretion of mucus--irritation --increase capillary permeability--
2) Bronchoconstriction --tachypnea, air trapping,

Ventilation in decreased however have full perfusion so V/Q ratio is low.]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714854 paulinewong1 https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714856 -inflammation of lower airway-- more mucus production--Dyspnea
-Bronchoconstriction--Air trapping--cause decrease O2 delivery to alveoli (increase intra-alveolar pressure)-- decrease in alveoli ventilation]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714856 paulinewong1 https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714858 Initially type 1 (hypocapnic) leading to type 2 RF for severe asthma]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714858 paulinewong1 https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714859 Respiratory Acidosis due to high pH, low pa02 and normal Pco2 later stage high paCO2, failing to ventilate properly]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714859 paulinewong1 https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714861 *SOB and Wheezing due to narrowing of airway
*Cough sec to increased mucous production
*Loss of consciousness, Confusion and drowsiness -due to hypoxia 
*Tachycardia, central cyanosis
Initially expiratory wheeze on auscultation.. in late stage a silent chest develops as ventilations cease
Use of accessory muscle]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714861 paulinewong1 https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714862 Pulsus Paradoxus
Pulsus paradoxus is a phenomenon when your blood pressure decreases with inhalation (breathing in)

Inspiration -> increased venous return -> RV enlargement -> Septum pushes into LV -> Decreased filling of LV -> Decreased stroke volume, BP

Inspiration -> Lungs expand -> Pulmonary vasculature expands -> More blood pools in lungs -> Decreased LV filling -> Decreased SV, BP]]> 2023-03-08 00:24:06 UTC https://padlet.com/paulinewong1/e94xoy1gjhnbvwek/wish/2507714862
