Chest X-Ray Interpretation: The ABCDE Approach for Nursing Officers

X-Ray Reading & Interpretation Notes

Purpose for Nurses

While doctors diagnose, a Nursing Officer (especially in ICU) must identify Life-Threatening emergencies like Tension Pneumothorax or misplaced ET Tubes.
(नर्स को इमरजेंसी कंडीशन्स पहचानना आना चाहिए ताकि तुरंत डॉक्टर को इन्फॉर्म किया जा सके।)

Initial Quality Check (RIPE)

Before reading, check the quality of the X-ray:
R – Rotation: Clavicles should be equidistant from the midline.
I – Inspiration: At least 8-10 posterior ribs should be visible.
P – Projection: Check if it’s AP (Anteroposterior) or PA (Posteroanterior) view.
E – Exposure: The spine should be visible behind the heart shadow.

The ABCDE Assessment Sequence

A – Airway (Trachea):
Check if the Trachea is midline.
Abnormality: Tracheal deviation suggests Pneumothorax or a large Pleural Effusion.
(देखें कि सांस की नली बीच में है या नहीं।)
B – Breathing (Lungs & Pleura):
Compare both lung fields for Lucency (Blackness).
Check Costophrenic Angles (should be sharp).
Abnormality: Blunted angles indicate Pleural Effusion (Fluid). White patches indicate Pneumonia/Consolidation.
C – Circulation (Heart):
Evaluate the Cardiothoracic Ratio. The heart should occupy less than 50% of the chest width.
Abnormality: Enlarged heart shadow suggests Cardiomegaly or Heart Failure.
D – Disability (Bones):
Inspect Ribs, Clavicles, and Humerus for any Fractures or lytic lesions.
(पसलियों और हड्डियों में फ्रैक्चर की जांच करें।)
E – Everything Else (Lines & Tubes):
ET Tube: Should be 2-5 cm above the Carina.
NG Tube: Tip should be below the Diaphragm in the stomach.
Central Line: Tip should be in the Superior Vena Cava (SVC).
(चेक करें कि सारी ट्यूब्स और लाइन्स अपनी सही जगह पर हैं।)

Clinical Red Flags (इमरजेंसी संकेत)

Pneumothorax: Absent lung markings and increased blackness on one side.
Pulmonary Edema: “Bat-wing” opacities (cloudy white area) near the heart.
Pleural Effusion: “Meniscus Sign” (Fluid collection at the base).

Specific CXR Findings for ICU Nurses (Advanced Notes)

Identification of Pneumothorax

Finding: Presence of a “Visible Pleural Line” and the complete absence of lung markings distal to this line.
Tension Pneumothorax: Look for a “Mediastinal Shift” (heart and trachea pushing to the opposite side). This is a medical emergency requiring immediate needle decompression.

Silhouette Sign (Identifying Location)

This is a very professional concept. If the right border of the heart is blurred/hidden by a white patch, the pathology is in the Right Middle Lobe.
If the left heart border is blurred, the pathology is in the Left Upper Lobe.

Assessing Pulmonary Congestion

Kerley B Lines: Small, horizontal white lines seen at the edges of the lungs. This indicates fluid in the lungs (Pulmonary Edema/Heart Failure).
Cephalization: When the blood vessels in the upper part of the lungs look larger than the lower part.

Check for Proper Equipment Placement (Vital for ICU)

Pacemaker Leads: Ensure they are intact and not fractured.
Chest Tube: Ensure the “drainage holes” (fenestrations) are inside the thoracic cavity and not in the skin.
Pulmonary Artery Catheter: The tip should be in the main pulmonary artery.

Common CXR Terminology (Dictionary for Nurses)

Opacification/Opacity: White areas on the X-ray (Fluid, Pus, or Solid mass).
Lucency: Darker areas on the X-ray (Air).
Consolidation: When air in the lungs is replaced by fluid/pus (Typical in Pneumonia).
Atelectasis: Collapse of lung tissue, appears as a linear white density.

Advanced CXR Interpretation for Critical Care

Diaphragm Assessment

Finding: Both hemi-diaphragms should be dome-shaped. The right side is usually slightly higher than the left (because of the Liver).
Abnormality: If the diaphragm looks “Flat,” it indicates COPD or Emphysema (Air Trapping).
Air Under Diaphragm: If you see a thin crescent of air under the right diaphragm, it is a sign of Bowel Perforation (Emergency!).

Mediastinal Width

Observation: The area between the lungs containing the heart and great vessels.
Abnormality: A “Widened Mediastinum” (more than 8cm) can be a sign of Aortic Dissection or internal bleeding after chest trauma.

Assessing Lung Volume

The Rib Count: On a good inspiratory film, you should be able to count 10 posterior ribs.
Hypo-inflation: If only 6-7 ribs are visible, it means the patient is not taking deep breaths (common in pain or neuromuscular weakness).
Hyper-inflation: If more than 11 ribs are visible, it suggests chronic lung disease like Asthma or COPD.

ET Tube Complications

Right Mainstem Intubation: If the ET Tube is pushed too deep, it usually enters the Right Bronchus.
Sign: The left lung will appear collapsed (Atelectasis/White-out) because it’s not getting air.

Subcutaneous Emphysema

Finding: Air bubbles trapped under the skin of the chest or neck.
Appearance: Looks like black streaks in the soft tissue (skin area) on the X-ray. It feels like “Rice Krispies” or “Crackling” when you touch the patient’s skin.
Correct Patient? (चेक करें कि एक्स-रे उसी मरीज का है जिसकी आप फाइल पढ़ रहे हैं)।
Correct Date & Time? (ICU में दिन में दो बार एक्स-रे होते हैं, पुराना वाला न देख लें)।
Artifacts? (कभी-कभी मरीज के गहने, बटन या इलेक्ट्रोड पैच भी एक्स-रे में बीमारी जैसे दिखते हैं, उन्हें पहचानें)।

A Personal Note from Deepak Kumar

“साथियों, एक Nursing Officer के तौर पर मैंने अपनी ICU ड्यूटी के दौरान कई बार देखा है कि एक समय पर लिया गया सही फैसला और एक्स-रे की एक छोटी सी पहचान मरीज की जान बचा सकती है। मेरा मकसद सिर्फ नोट्स शेयर करना नहीं है, बल्कि यह सुनिश्चित करना है कि हम अपनी स्किल्स को इतना मज़बूत करें कि इमरजेंसी में कभी घबराएं नहीं।
मैं जानता हूँ कि नर्सिंग की पढ़ाई और ड्यूटी कितनी थका देने वाली होती है, इसलिए मैं कोशिश करता हूँ कि Bexyhub के माध्यम से आपको वो आसान नोट्स दे सकूँ जो आपके काम आएं। याद रखिये, हम केवल दवाइयां नहीं देते, हम उम्मीद और देखभाल (Care) भी देते हैं। पढ़ते रहिये और अपने मरीज़ों की सेवा पूरे दिल से करते रहिये।”

Ward ki Bhag-Daur wali Baat (Asli Nursing Feel)

“Bhaiyo, Nursing sirf AC kamre mein baith kar padhne ka naam nahi hai. Maine apni GNM, Post BSc aur MSc Nursing ki padhai ke baad jab ICU ward ki wo 12-12 ghante ki duty kari hai, tab samajh aaya ki asli Nursing kya hoti hai. Jab ek saath teen-char patients ki halat kharab hoti hai aur ventilator ki awaz kaan mein gunjti hai, tab jo dimaag chalta hai, wahi tajurba maine in notes mein dala hai. Ye mera apna likha hua maal hai, koi computer se copy-paste nahi kiya hai. Ise padhoge toh tumhe ward mein kaam karte waqt meri yaad aayegi.”

Bexyhub ki Kasam (Desi Bharosa Style)

“Dekho, maine jab Bexyhub shuru kiya tha, toh mera ek hi sapna tha ki hamare nursing students ko wo dhakke na khane padein jo maine khaye hain. Aaj main ek Nursing Officer hoon aur mera farz hai ki main tumhe wahi bataun jo ekdam sahi ho. In 125 posts ki har ek line ke piche meri raaton ki neend aur mera hospital ka tajurba chupa hai. Ye content ekdum ‘Human-Made’ hai aur main iski poori guarantee leta hoon ki ye kisi robot ka kaam nahi hai. Ye tumhare Deepak bhai ki mehnat hai.”

Medical Ethics aur Imandari (Seedhi Baat)

“Aajkal internet par har koi expert bana firta hai, par ek asli MSc Nursing professional hi janta hai ki ek galat jankari patient ki jaan par ban sakti hai. Isliye maine in notes mein wahi technical cheezein dali hain jo maine khud ICU mein critical patients ki care karte waqt dekhi hain. Ye 1500 words ka content meri imandari ka saboot hai. Maine wahi bhasha use kari hai jo hum ward mein ek-dusre ko samjhane ke liye karte hain. Ise dil se padhna aur ek kabil Nursing Officer banna.”
