Definition of COPDDefinition of COPD
Chronic obstructive pulmonary disease(COPD) is a disease state characterized by airflow limitation that is not fullyreversible. The airflow limitation is usuallyboth progressive and associated with anabnormal inflammatory response of thelungs to noxious particles or gases.

While smokers who are unable orunwilling to quit may derive limited
benefit from partial smoking reduction, complete smoking
cessation remains a necessity forthose wanting to minimise all of
the harmfuleffects of smoking.

A total of 86 cases and 86 control subjects were included, (FEV1 39% prd)
Multivariate logistic regression showed the following risk (or protective) factors of COPD hospitalization:
• three or more COPD admissions in the previous year (oddsratio [OR] 6.21, p<0.008);
• FEV1 (OR 0.96 per percentual unit, p<0.0005);
• underprescription of long-term oxygen therapy (LTOT) (OR 22.64, p<0.007);
• and current smoking (OR 0.30, p<0.022).

Time course of pulmonary function before admission into ICU.A two-year retrospective study of COLD patients with hypercapnia
M Vitacca, K Foglio, S Scalvini, S Marangoni, A Quadri and N Ambrosino
Controlled study:Time course of 2 years before admission in ICU for 16 pts vs 15 controls.
The results indicated that:
Basal body weight,Rate of deterioration over time in:•FEV1•VC,•blood gas values,•bicarbonates, •RVD
may be related to the necessity of ICU admission in COLD patients with hypercapnic respiratory insufficiency.

Risk stratification of NPPV failure was assessed in 1,033 consecutive patients admitted toexperienced hospital units, including two intensive care units, six respiratory intermediate care units, and five general wards. NPPV was successful in 797 patients.

CONCLUSIONI
Grazie al miglioramento delle cure, sempre più pazienti respiratoriarrivano a vivere una condizione di prolungata sopravvivenzacon problematiche di grave cronicità
La gestione della BPCO è divenuta ormai una complessa presa in carico(di tutte le figure professionali) di sintomi fisici e psicosociali,dipendenze, problematiche multidisciplinari e multifattoriali.
Operatori sanitari e famiglia devono sempre più collaborare per prendere comuni decisioni cliniche ed etiche
