What is the difference between hypoxic and hypercapnic respiratory failure?


Intensive Care Nephrology

ESRD ptns are particularly vulnerable to severe COVID-19 (older age & high frequency of co-morbidity, e.g. DM & HT, in this cohort. The ASN & ISN hv issued guidelines and a list of resources to guide nephrologists to provide life-sustaining DX care. These resources that continue to evolve are frequently updated, including the following: early recognition & isolation of individuals with respiratory Sm(s); ptn separation & cohorting within waiting areas and within DX unit; use of personal protective equipment in DX unit; with added measures for ptns with confirmed/suspected COVID-19.

Q.429. What is the difference between hypoxic & hypercapnic respiratory failure?

 A. Hypoxic Resp. failure c Failure to maintain adequate oxygenation.

Hypercapnic Resp. failure c inadequate ventilation c Co2 retention.

Q.430. What are the possible modes of mechanical ventilation in I.C.U.?

A. Modes of Mch.v.:

I. Volume-cycled: certain “tidal volume” delivered by the ventilator: SIMV (Synchronized Intermittent Mandatory Ventilator) & CMV (Continuous Mandatory Ventilation).

II. Pressure-cycled ventilation: volume is delivered until pre-set maximum pressure is reached = P.C.V. = pressure controlled ventilation.

III. Flow-cycled ventilation : “inspiration” continued until a pre-set flow rate is reached ( P.S.V.) = Pressure Support Ventilation.

CMV: Minimizes the work of breathing done by the ptn., it is used in ptn. é  myocardial ischemia or profound hypoxemia, e.g. COPD & tachypnea ptn..

Q.431. What is the etiology of ARDS?
