    KK Aggarwal

    In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will talk about the evaluation in a patient with COPD. He says that in every patient of asthma or COPD, they are made to walk for 6 minutes and measure the distance travelled during these 6 minutes. The baseline SPO2 levels are checked along with before and after walking. If the SPO2 levels falls more than 4%, then he is not stable.

  • At what levels, oxygen is given?
    At what levels, oxygen is given?
    KK Aggarwal

    In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will discuss the levels at which oxygen is started. He says that this question is asked by nurses or junior doctors whether each patient has to be started oxygen when admitted in the hospital. The indication for oxygen is when the SPO2 level is less than 88%. SPO2 level is abnormal if it is less than 95%.

    Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will explain in details about obstructive sleep apnea in this video. It means the patient has snoring and with it he also has episodes of apnea spells. The person’s respiration stops during sleep and can be checked by a sleep study.

  • Explain overnight pulse oximetry?
    Explain overnight pulse oximetry?
    KK Aggarwal

    Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will explain overnight pulse oximetry in details in this video. Many a times, the patient’s overnight oxygen desaturation needs to be checked. It is generally done in patients with asthma, sleep apnea, COPD, heart failure, etc. and check for more than 4% desaturation. If the patient has more than 10 levels of desaturation levels in an hour then it is a positive desaturation index.

  • In which situations of carbon monoxide poisoning is the patient shifted to hyperbaric oxygen?
    In which situations of carbon monoxide poisoning is the patient shifted to hyperbaric oxygen?
    KK Aggarwal

    In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will talk about the situations of carbon monoxide poisoning and when is the patient shifted to hyperbaric oxygen. Carbon monoxide poisoning is generally lethal but there are times where they are survived and have end organ ischemia, severe metabolic acidosis, overt respiratory failure, etc. In all these situations, hyperbaric oxygen is necessary.

  • What is AHI?
    What is AHI?
    KK Aggarwal

    The video will explain about AHI by Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks. Apnea–Hypopnea Index is measured to indicate the severity of sleep apnea. He will explain the parameters of the study and the values according to the saturation levels. If AHI is more than 5 and is symptomatic then he needs treatment. And if the AHI is more than 15, then he needs treatment.

  • How is pulmonary embolism diagnosed?

  • What is the management of acute respiratory distress syndrome (ARDS)?
    What is the management of acute respiratory distress syndrome (ARDS)?
    Anil Gurnani

    Dr. Anil Gurnani, Group Director, Intensive Care & Anesthesiology, Kailash Group of Hospitals, will discuss the management of acute respiratory distress syndrome (ARDS) in this video. In mild ARDS, if the patient is hemodynamically stable and conscious, then non invasive ventilation can be tried. He will further explain that if the patient is hemodynamically unstable and is drowsy and PaO2:FiO2 ration is less than 150, then do not wait for non invasive ventilation to continue. Immediately start early invasive ventilation. He will further explain the invasive ventilation management is ARDS patients.

  • What is the management of acute respiratory distress syndrome (ARDS)?
    What is the management of acute respiratory distress syndrome (ARDS)?
    Rajesh Chawla

    In this video, Dr. Rajesh Chawla, Senior Consultant, Institutes of Critical Care Respiratory and Sleep Medicine, Indraprastha Apollo Hospitals, New Delhi, will talk on the management of acute respiratory distress syndrome (ARDS). He will explain that if a person has got acute illness which is less than 7 days and it recurs in less than 7 days after the initial infection and if cardiogenic shock is ruled out then probably he has ARDS. Dr. Chawla will explain that in ARDS, the causative factor should be treated and the management given to them.
