This document provides information on interpreting arterial blood gases (ABGs), including:
1) How to identify acidosis or alkalosis based on pH levels.
2) The Rome method for determining if a pH change is due to respiratory or metabolic causes based on pCO2 and HCO3 levels.
3) Examples of respiratory acidosis, respiratory alkalosis, and metabolic alkalosis and how they may present on ABGs.
4) How the body can partially or fully compensate for acid-base imbalances through changes in HCO3 or pCO2.
5) Formulas like Winter's formula and the Anion Gap that can help evaluate compensation and identify causes of metabolic acidosis
This presentation discuss about acid-base-gas normal ratio and its indication in relation to varying abnormal level and how to manage it. This includes clinical analysis practice.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
2. 1. Iidentify Acidosis or alkalosis
2. PH 7.35 to 7.45
3. Ph <7.35 Acidosis
4. Ph >7.45 Alkalosis
5. Ph =7.40 absolute
6. Ph 7.35 to 7.40 Acidosis Range
7. Ph 7.40 to 7.45 Alkalosis range
3. METABOLIC OR RESPIRATORY
• Rome Method
• Ph decreased, pco2 Increased =respiratory disorder
• Ph decreased pco2 decreased = metabolic disorder
• 2. More co2 more H+ Acidosis ph will be less
• More hco3 alkalosis more ph
• Tic tac toe mathod
7. COMPENSATION
• Partially or fully compensated
• In case of respiratory Acidosis hco3 will inc to compensate
• In case of respiratory alkalosis Hco3 will dec
In case of metabolic Acidosis co2 will decrease
In case of metabolic alkalosis co2 will increase
8. EXAMPLE
• Ph 7.30 co2 50 hco3 49
• ph dec Acidosis
• Co2 inc.. Leading to increase in H+
• Hco3 inc to compensate
• respiratory Acidosis partially compensated
10. FULLY COMPENSATED
• PH shoull be i with in normal range
• e. G
• ph7.44 Pco2 48 hco3 35
• Ph is normal but more in alkalosis range so alkalosis
• hco3 s increased. So it’s metabolic
• Co2 inc
• Metabolic alkalosis fully compensated
12. WINTERS FORMULA
• Pco2 )(1.5 * hco3) +8 +- 2
• Eg if hco3 is 10
• Pco2 21 to 25. So.
• Co2 21 to 25 = adequate compensation
• Co2 < normal range = associated respiratory alkalosis
• Co2 > normal range = associated respiratory Acidosis
15. ANION GAP METABOLIC ACIDOSIS
• Anion gap = NA – (HCO3 +CL)
• NORMAL RANGE - 6 12
• NORMAL AG METABOLIC ACIDOSIS
• LOOS OF NAHCO3 OR GAIN HCL
• EG NS DIARRHEA Rta CAI
16. • Inc anion gap metabolic Acidosis
• HA ~H+ A-
• Dka Lactic Acidosis toxins
• Dec anion gap metabolic Acidosis
• Mm / HYPERPARATHYRIDISm
17. DELTA DELTA GAP
• Diff in AG / diff in Hco3 = Ag – 12/ 24-hco3
• HA~ H+. A-
• H+ + HCO3 = H2CO3
• SO,.
• DIFF IN AG / DIFF IN HCO3 =1 ~~ PROPTIONAL LOSS OF HCO3 FOR EVERY
H+ ( PURE ANION GAP METABOLIC ACIDOSIS)
18. • Diff in AG /diff in Hco3 >1 less loss of hco3 than h+ generated (Superimposed
metabolic alkalosis)
• Diff in AG!/ diff in Hco3 < 1 more hco3 lost than h generated (Superimposed
metabolic Acidosis)
