Pulmonary Flashcards
Diagnostic test for bronchiactesis?
HRCT
Patient with dyspnea and dry cough, O/E dullnes in lower left lung zone with decreased breath sound, reduced lung expansion, best next step??.
Erect CXR
lateral decubetus
CT chest
Lateral decubetus CXR are the most sensitive x-ray and can detect small PE
this is pleural effusion case
Erect CXR detect >300ml fluid
Lateral CXR detect >50ml fluid
US detect >5 ml fluid 😱

Challenge
Mention all the 5 indication of diagnostic thoracosentesis (aka pleurocentesis )😏
You did diagnostic thoracocentesis for patient with PE, the result are inconclusive and you still don’t know the diagnosis 😣, next step?
Rule out malignancy
Ddx of pleural effusion with low glucose? And which one has the lowest glucose level ever?
RA pleurisy has the lowest, veeerrrrry low (<30)
What is the indication of THERAPEUTIC thoracocentesis ?
Large effusion with dyspnea and/or cardiac decompensation
Complicated parapneumonic effusions
Patient with large pulmonary effusion due to TB, was treated in king Khalid hospital were they drained 3L at once, after 3hr patient developed dyspnea, frothy sputum and cough, what is the next step??
CXR
Re-expansion syndrome
Pleural fluid criteria for complicated parapneumonic effusion
PH ?
LDH ?
Glucose ?
pH (very acidic ) < 7.2
High LDH
Low glucose <60mg
Alcoholic patient with poor dental hygiene, developed acute cough dyspnea fever with currant jelly sputum, CXR show consolidation
What is the organism.
Patient developed pneumonia after 7 days of intubation, most likely organism?
Areej ☺️
Patient with fever and productive cough
You do CXR shows cavity, next imaging?
CT
When to consider failure of TB management?
Positive culture at 5 months
You diagnosed a patient with active TB, next step immediately to prevent disease spread😱😱
airborne negative pressure isolation 😷
+N95 mask
Young person got COPD, what is your differential !
Patient with COPD and FEV1 is 35, this is GOLD class what?
3
What is the Indications for NIPPV in COPD patient
Respiratory acidosis: PH <7.35 or
hypercapnia → PCO2 >45 2)
RR > 25/min with fatigue of respiratory muscles
Procedure: BiPAP (M/C used)
In COPD you should maintain O2 in range of ?
88-92
Mention as much as you can from the indication of mechanical ventilation in COPD
FEV1/FVC =78 , TLC =40 , diagnosis.
Restrictive lung disease
Patient with acute pulmonary edema , best way to deliver O2 ?
Face mask
Venturi mask
High flow O2 nasal canula
Low flow nasal canula
Best O2 mask for COPD patient?
When its better to use CPAP and when to use BIPAP
COPD patient , not well controlled with albeturol , what to add?
COPD patient with O2 85% at rest, what to add?
Long term o2 therapy is indicated if
2 readings of ABG (when patient is not in attack ) are paO2 <55
Asthmatic patient in acute attck
He can speak in words, agitated, sitting in tripod position, O2 88%,
Is it mild , moderate, severe or life-threatening attack?
Severe
If you have no time just remeber the severe and life-threatening, many Q on this topic
Remember : PEFR, HR, Po2
Vaccines recommended for asthmatic patient?
Influenza + pneumococcal for all
Which drug from asthma drug increases risk of death if used alone ! ☠️
LABA (formoterol, salmoterol )
Patient in acute asthma attach
Yoy noticed that th CO2 level changed form low to normal, next step?☠️☠️☠️☠️
Intubation
Normal or high CO2 is sign of respiratory failure 😞
Indication of intubation ( respiratory acidosis + normalization or high CO2 )
In patient with obstructive pattern in PFT, all parameter usually low except one thin is high, what is it??
TLC
Young patient with SUDDEN onset and OFFSET or recurrent episodes of SOB + STRIDOR with exercise, with no allergy family history of asthma and no response to ventolin.
, DX?
vocal cord dysfunction
Remeber , stridor = URT symptoms
Differential diagnosis of difficult to control asthma?.
When is positive methacholine test ?
If there is fall in FEV1 > 20%
In any asthma pt who don’t respond to medications, you need to check for?
Proper Use of the inhaler
Add spacer
Medication adherence
Last drug we can try to help patient in acute severe asthma attack before going for intubation?
Mg sulfate
Drugs that are contraindicated in asthamtic patient ?
Mention 5
Management of exercise induced asthma
SABA 30 min before exercise
Most important parameter to monitor progression of COPD??.
FEV1
What measures improve survival = reduce mortality in COPD ?
Smoking cassation + O2 therapy + NPPV + vaccination (MCC of exacerbation is infection)
Only
What changes in ECG you found in COPD patient ?
And ttt
Dx: MAT
Mx: amiodarone
COPD patient developed a secondary pneumothorax (size 2cm) , Mx?
Any secondary pneumothorax is treated by chest tube regardless of size
Patient with incidental finding of solitary lundpg nodule, there was no previous imaging so, CT obtain and nodule measured 1cm , next step?
Any nodule >8mm ===== biopsy
Lung cancer + low PTH + high Ca
What is the cause?
PTH related peptide
Gives -ve feedback and inhibit PTH hormane + rise the level of Ca
Common in non-small cell lung cancer (sqaumous cell cancer )
Lung nodule in non-smoker, with popcorn calcification
